"Journal of Clinical and Diagnostic Research is at present a well-known Indian originated scientific journal which started with a humble beginning. I have been associated with this journal since many years. I appreciate the Editor, Dr. Hemant Jain, for his constant effort in bringing up this journal to the present status right from the scratch. The journal is multidisciplinary. It encourages in publishing the scientific articles from postgraduates and also the beginners who start their career. At the same time the journal also caters for the high quality articles from specialty and super-specialty researchers. Hence it provides a platform for the scientist and researchers to publish. The other aspect of it is, the readers get the information regarding the most recent developments in science which can be used for teaching, research, treating patients and to some extent take preventive measures against certain diseases. The journal is contributing immensely to the society at national and international level."

" Journal of Clinical and Diagnostic Research (JCDR) is a multi-specialty medical and dental journal publishing high quality research articles in almost all branches of medicine. The quality of printing of figures and tables is excellent and comparable to any International journal. An added advantage is nominal publication charges and monthly issue of the journal and more chances of an article being accepted for publication. Moreover being a multi-specialty journal an article concerning a particular specialty has a wider reach of readers of other related specialties also. As an author and reviewer for several years I find this Journal most suitable and highly recommend this Journal."

"It gives me great pleasure to be associated with JCDR, since last 2-3 years. Since then I have authored, co-authored and reviewed about 25 articles in JCDR. I thank JCDR for giving me an opportunity to improve my own skills as an author and a reviewer.
It 's a multispecialty journal, publishing high quality articles. It gives a platform to the authors to publish their research work which can be available for everyone across the globe to read. The best thing about JCDR is that the full articles of all medical specialties are available as pdf/html for reading free of cost or without institutional subscription, which is not there for other journals. For those who have problem in writing manuscript or do statistical work, JCDR comes for their rescue.
The journal has a monthly publication and the articles are published quite fast. In time compared to other journals. The on-line first publication is also a great advantage and facility to review one's own articles before going to print. The response to any query and permission if required, is quite fast; this is quite commendable. I have a very good experience about seeking quick permission for quoting a photograph (Fig.) from a JCDR article for my chapter authored in an E book. I never thought it would be so easy. No hassles.
Reviewing articles is no less a pain staking process and requires in depth perception, knowledge about the topic for review. It requires time and concentration, yet I enjoy doing it. The JCDR website especially for the reviewers is quite user friendly. My suggestions for improving the journal is, more strict review process, so that only high quality articles are published. I find a a good number of articles in Obst. Gynae, hence, a new journal for this specialty titled JCDR-OG can be started. May be a bimonthly or quarterly publication to begin with. Only selected articles should find a place in it.
An yearly reward for the best article authored can also incentivize the authors. Though the process of finding the best article will be not be very easy. I do not know how reviewing process can be improved. If an article is being reviewed by two reviewers, then opinion of one can be communicated to the other or the final opinion of the editor can be communicated to the reviewer if requested for. This will help one’s reviewing skills.
My best wishes to Dr. Hemant Jain and all the editorial staff of JCDR for their untiring efforts to bring out this journal. I strongly recommend medical fraternity to publish their valuable research work in this esteemed journal, JCDR".

"I wish to thank Dr. Hemant Jain, Editor-in-Chief Journal of Clinical and Diagnostic Research (JCDR), for asking me to write up few words.
Writing is the representation of language in a textual medium i e; into the words and sentences on paper. Quality medical manuscript writing in particular, demands not only a high-quality research, but also requires accurate and concise communication of findings and conclusions, with adherence to particular journal guidelines. In medical field whether working in teaching, private, or in corporate institution, everyone wants to excel in his / her own field and get recognised by making manuscripts publication.


Authors are the souls of any journal, and deserve much respect. To publish a journal manuscripts are needed from authors. Authors have a great responsibility for producing facts of their work in terms of number and results truthfully and an individual honesty is expected from authors in this regards. Both ways its true "No authors-No manuscripts-No journals" and "No journals–No manuscripts–No authors". Reviewing a manuscript is also a very responsible and important task of any peer-reviewed journal and to be taken seriously. It needs knowledge on the subject, sincerity, honesty and determination. Although the process of reviewing a manuscript is a time consuming task butit is expected to give one's best remarks within the time frame of the journal.
Salient features of the JCDR: It is a biomedical, multidisciplinary (including all medical and dental specialities), e-journal, with wide scope and extensive author support. At the same time, a free text of manuscript is available in HTML and PDF format. There is fast growing authorship and readership with JCDR as this can be judged by the number of articles published in it i e; in Feb 2007 of its first issue, it contained 5 articles only, and now in its recent volume published in April 2011, it contained 67 manuscripts. This e-journal is fulfilling the commitments and objectives sincerely, (as stated by Editor-in-chief in his preface to first edition) i e; to encourage physicians through the internet, especially from the developing countries who witness a spectrum of disease and acquire a wealth of knowledge to publish their experiences to benefit the medical community in patients care. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help. JCDR provides authors help in this regards.
Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc. This is one of the great reasons for authors to submit their work with JCDR. Another best part of JCDR is "Online first Publications" facilities available for the authors. This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers.
Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.JCDR is indexed with Embase & EMbiology, Google Scholar, Index Copernicus, Chemical Abstracts Service, Journal seek Database, Indian Science Abstracts, to name few of them. Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn.
In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. Of course there is always a scope for improvement in every field and none is perfect. To progress, one needs to identify the areas of one's weakness and to strengthen them.
It is well said that "happy beginning is half done" and it fits perfectly with JCDR. It has grown considerably and I feel it has already grown up from its infancy to adolescence, achieving the status of standard online e-journal form Indian continent since its inception in Feb 2007. This had been made possible due to the efforts and the hard work put in it. The way the JCDR is improving with every new volume, with good quality original manuscripts, makes it a quality journal for readers. I must thank and congratulate Dr Hemant Jain, Editor-in-Chief JCDR and his team for their sincere efforts, dedication, and determination for making JCDR a fast growing journal.
Every one of us: authors, reviewers, editors, and publisher are responsible for enhancing the stature of the journal. I wish for a great success for JCDR."

Dr. Shankar P.R.

"On looking back through my Gmail archives after being requested by the journal to write a short editorial about my experiences of publishing with the Journal of Clinical and Diagnostic Research (JCDR), I came across an e-mail from Dr. Hemant Jain, Editor, in March 2007, which introduced the new electronic journal. The main features of the journal which were outlined in the e-mail were extensive author support, cash rewards, the peer review process, and other salient features of the journal.
Over a span of over four years, we (I and my colleagues) have published around 25 articles in the journal. In this editorial, I plan to briefly discuss my experiences of publishing with JCDR and the strengths of the journal and to finally address the areas for improvement.
My experiences of publishing with JCDR: Overall, my experiences of publishing withJCDR have been positive. The best point about the journal is that it responds to queries from the author. This may seem to be simple and not too much to ask for, but unfortunately, many journals in the subcontinent and from many developing countries do not respond or they respond with a long delay to the queries from the authors 1. The reasons could be many, including lack of optimal secretarial and other support. Another problem with many journals is the slowness of the review process. Editorial processing and peer review can take anywhere between a year to two years with some journals. Also, some journals do not keep the contributors informed about the progress of the review process. Due to the long review process, the articles can lose their relevance and topicality. A major benefit with JCDR is the timeliness and promptness of its response. In Dr Jain's e-mail which was sent to me in 2007, before the introduction of the Pre-publishing system, he had stated that he had received my submission and that he would get back to me within seven days and he did!
Most of the manuscripts are published within 3 to 4 months of their submission if they are found to be suitable after the review process. JCDR is published bimonthly and the accepted articles were usually published in the next issue. Recently, due to the increased volume of the submissions, the review process has become slower and it ?? Section can take from 4 to 6 months for the articles to be reviewed. The journal has an extensive author support system and it has recently introduced a paid expedited review process. The journal also mentions the average time for processing the manuscript under different submission systems - regular submission and expedited review.
Strengths of the journal: The journal has an online first facility in which the accepted manuscripts may be published on the website before being included in a regular issue of the journal. This cuts down the time between their acceptance and the publication. The journal is indexed in many databases, though not in PubMed. The editorial board should now take steps to index the journal in PubMed. The journal has a system of notifying readers through e-mail when a new issue is released. Also, the articles are available in both the HTML and the PDF formats. I especially like the new and colorful page format of the journal. Also, the access statistics of the articles are available. The prepublication and the manuscript tracking system are also helpful for the authors.
Areas for improvement: In certain cases, I felt that the peer review process of the manuscripts was not up to international standards and that it should be strengthened. Also, the number of manuscripts in an issue is high and it may be difficult for readers to go through all of them. The journal can consider tightening of the peer review process and increasing the quality standards for the acceptance of the manuscripts. I faced occasional problems with the online manuscript submission (Pre-publishing) system, which have to be addressed.
Overall, the publishing process with JCDR has been smooth, quick and relatively hassle free and I can recommend other authors to consider the journal as an outlet for their work."

Abstract

Introduction: Tibia, being anatomically placed subcutaneously throughout its length, is very prone to fractures. Incidence of extra-articular proximal tibia fractures accounts for 5-11% of all tibia shaft fractures. Among the various treatment modalities available, locked intramedullary nailing is a safe and adequate modality with fewer complications. Expert tibia nail is anatomically designed with multi-directional locking, which attains better angular stability and thereby allowing fixation of very proximal fractures.

Aim: To analyse and assess the functional and radiological outcome of expert tibia nailing used for treating extra-articular proximal-third tibia fractures.

Materials and Methods: A longitudinal cohort study was conducted for a duration of three years and five months, which included 31 patients. Standard descriptive statistical method was used to describe parameters. All these patients had extra-articular proximal-third tibia fractures and were managed with expert tibia nail. All patients underwent clinical and radiological evaluation based on the Klemm and Borner scoring system at a regular interval of six weeks, three months, six months, and at one year.

Results: The most common mode of injury was road traffic accidents (80.64%). Patients were in the age group of 26-63 years with an average mean of 41.80±9.7 years. The male to female ratio was 4.16:1, suggestive of male predominance. According to the Klemm and Borner scoring system, 71.42% of patients belonged to the excellent group, 17.85% were in good, 7.14% in fair and 3.57% in poor. Radiological union was achieved in an average period of 20.9±2.09 weeks.

Conclusion: In this study, scores obtained on the basis of Klemm and Borner scoring system, depicts that intramedullary expert tibia nailing is a good treatment modality for the management of extra-articular proximal-third tibia fractures, which provides good angular stability and adequate fixation resulting in early rehabilitation and union with excellent functional outcome and mere complications. It is also a safer treatment modality in case of compromised surrounding soft tissue.

Fracture of the tibia is a common long bone injury due to high energy trauma occurring secondary to motor vehicle accidents and fall from height with an annual incidence of 26 per 1,00,000 individuals (1). Extra-articular proximal tibia fractures account for 5-11% of all tibia shaft fractures (2). Due to the tibia’s presence in subcutaneous location, its structural anatomy, and sparse anteromedial soft tissue coverage, the tibia is subjected to frequent injuries. It is also commonly associated with compound fractures than any other long bone in the body (3).

Various treatment modalities present for the management of tibia fractures include both conservative and surgical methods. The conservative method comprises of closed reduction and cast application, which commonly results in delayed union, malunion, and restricted range of motion at the ankle and knee joint (4). To reduce the complications associated with conservative treatment, there is an increasing trend towards surgical management, which involves methods like open reduction and internal fixation with plates, Intramedullary Nailing (IMN), and external fixation, each having their own indications, advantages, and disadvantages (5),(6),(7).

The preferred surgical modality for such fractures is Intramedullary fixation, being less invasive, load sharing, preserves extra-osseous blood supply, and fracture haematoma (8),(9),(10),(11). With the advent of new modern implants like Expert Tibia Nail, an anatomically customised IMN system which allows multidirectional interlocking of nail below the tibia plateau, thereby facilitating the surgeon to address and fix very proximal tibia fractures (12). Option of multidirectional locking and end caps, which blocks the most proximal oblique screw, helps attain absolute angular stability. Thus, expert tibia nailing system has led to significant advancement in the fixation of extra-articular proximal tibia fractures. The study aims to assess the functional and radiological outcome of expert tibia nailing technique in extra-articular proximal-third tibia fractures.

Material and Methods

A longitudinal cohort study was conducted at a tertiary care centre from August 2017 to December 2020 with a sample size of 31 patients after obtaining approval from Institutional Ethics Committee. Informed consents of patients were taken.

Inclusion criteria: The inclusion criteria for selecting patients in the study included skeletally mature patients ranging from 26-63 years with fractures classified as AO 41 A2/A3 (13), including both closed and compound fractures with grade 1 and 2 according to Gustilo-Anderson classification (14).

Exclusion criteria: Patients with intra-articular fracture, pathological and stress fracture, and those associated with ipsilateral limb fracture and neurovascular injury, and patients not willing or unfit for surgery were excluded from the study.

Patients who were fulfilling inclusion criteria and suspected fracture were adequately stabilised, and relevant X-rays were done. Closed fractures with severe swelling were adequately splinted with an above-knee slab and were given oral proteolytic enzymes and limb elevation along with ice pack application. Surgery was done after the subsidence of swelling. Open fractures after thorough primary debridement were dressed daily and were given broad-spectrum Intravenous (i.v) antibiotics. Once the wound condition was favourable for interventions, then surgery was planned.

Surgical Technique

Under spinal anaesthesia, in supine position on a radiolucent table with the leg positioned in a semi-extended position in 20-30 degrees of flexion by putting a small bolster under the thigh, vertical patella tendon splitting approach was used.

In the anteroposterior view, the entry was taken in line with the lateral tubercle of the intercondylar eminence and in lateral view, the proximal entry point was taken at the tibia plateau’s ventral edge to gain the maximum length of nail in the proximal fragment, under c-arm using curved bone awl. It is of utmost importance that the entry point is in the line of medullary canal is in order to place the nail adequately.

During the procedure, difficulties in reducing the fracture like apex anterior angulation of the proximal fragment and malalignments in coronal plane were encountered. To tackle the apex anterior angulation, the patient was placed in a semi-extended position, and blocking k-wires were placed in proximal fragment from medial to lateral cortex, anterior to fibula under fluoroscopy guidance (Table/Fig 1).

Similarly, one or two blocking k-wires were placed instead of poller screws in anteroposterior direction to counter coronal plane malalignments in such way that they neutralised the deforming forces during canal reaming and nail placement. Also, slight lateral entry was undertaken to avoid valgus malalignment. Same Anteroposterior blocking k-wires aided in preventing apex anterior angulation by applying downward directed force. Additional k-wires and AO reduction clamps were used for provisional fixation.

After appropriate alignment, guide-wire was passed anterior to the blocking k-wire, and reduction was achieved. Reaming was done over the guide-wire. After choosing the appropriate size nail, the whole assembly was passed over the guide-wire, followed by proximal and distal locking (Table/Fig 2), (Table/Fig 3). At the end, all blocking k-wires were removed.

On postoperative day 2 or 3, patients were mobilised and started with quadriceps strengthening exercises, knee and ankle mobilisation exercises, and non weight bearing-crutch walking. Initially, active knee flexion from 0 to 45 degrees was started and eventually was increased to 90 degrees, followed by passive range of motion exercises. Patients were discharged on day 5 after check dress. Patients with wound complication were discharged after adequate wound care and suture removal. After the completion of four weeks, patients were advised to start toe-touch weight bearing followed by partial weight-bearing from the sixth week with the help of walking aid and were shifted to full weight-bearing after eight weeks.

Data Collection, Follow-up and Evaluation

Data related to demographics, mode of trauma, details of hospitalisation, operative time, postoperative rehabilitation, complications, clinical and functional outcomes were collected during hospital stay and follow-up visits in the OPD clinic. Patients were followed-up at regular intervals of six weeks, three months, six months, and one year in the outpatient department. Functional outcome was assessed based on modified Klemm and Borner scoring system (15). Scoring was done by assessing the following factors such as pain, range of motions at knee and ankle, muscle atrophy, alignment and union on X-ray.

Statistical Analysis

Standard descriptive statistical method was used to describe parameters. Continuous variables were described using means, standard deviations, ranges, and tabulation was done accordingly.

Results

The baseline data of the 31 patients with fresh extra-articular proximal-tibia fracture is depicted in (Table/Fig 4).

It was seen that in the majority of the cases, road traffic accidents (80.64%) was the most common mode of injury, and the remaining were due to fall from height. All the patients belonged to the age group between 26 to 63 years, with the combined average age of 41.80±9.7 years. Males were more commonly affected than females with a male to female ratio of 4.16:1. Among these, 23 patients were of closed fractures, and eight were compound fractures (five patients of grade 1 and three patients of grade 2). The interval from injury to surgery ranged between 3-8 days with a mean of 5.35±1.56 days. Average hospital stay in was found to be 5.87±3.11 days. Out of 31 patients, one patient died in the postoperative period reason being not related to surgery, and two patients were lost to follow-up. The average time duration required for surgery was 111.19±10.62 minutes. In postoperative period, knee range of motion more than 90º was achieved up to six weeks in 23 (82.14%) of patients. Full weight bearing was achieved by three months in 25 patients. Among the 28 patients who were followed-up till radiological union, the union was seen in 25 (89.28%) patients. The other three cases united later on by intervening with bone grafting and revision surgery which led to delayed weight bearing at six months. After primary surgery, all those who achieved radiological union were united within 18-25 weeks with an average time duration of 20.9±2.09 weeks. In closed fractures, union was achieved earlier at an average of 20.08±1.53 weeks compared to compound fractures where it was at an average of 23.88±1.45 weeks (p-value=0.00001).

Patients’ functional outcome at each follow-up was assessed by using Klemm and Borner scoring system (Table/Fig 5), (Table/Fig 6). At final follow-up after 12 months, outcome was excellent in 20 (71.42%), good in 5 (17.85%), fair in 2 (7.14%) and poor in 1 (3.57%). Acceptable alignment was seen in 22 (78.57%) patients (criteria for acceptability was considered with average coronal and sagittal plane deformity less than 5°). The remaining 6 (21.42%) patients had coronal plane deformity (four varus and two valgus) of more than 5° but did not had any effect clinically.

The most common immediate complication in early postoperative was anterior knee pain, and mild to moderate restriction of movements was encountered in 8 cases (28.57%), which eventually resolved with physiotherapy. Other complications included surgical site infection with three superficial infections, which got cured by regular dressing and antibiotics, and one deep infection case, which was managed with debridement and antibiotic treatment. In the postoperative period, no cases of compartment syndrome or neurovascular complication were reported.

Discussion

Despite the availability of various treatment modalities for the fixation of extra-articular proximal tibia fractures, it still poses an impending dilemma to orthopedic surgeons. It is quite tough to establish and individualise a particular treatment modality for proximal tibia fractures. Thus, each and every fracture has to be assessed individually and planned accordingly.

Proximal tibia fractures are associated with high-velocity injuries leading to severe soft tissue compromise. In such case, conventional method of open reduction and plating is associated with complications like infection, flap necrosis, varus collapse and knee stiffness (16). Other modalities like percutaneous plating methods (MIPO) or IMN fixation for extra-articular proximal tibia fractures are being largely recommended. The IMN fixation gives an added benefit of being a load-sharing device that allows early weight-bearing. Though they are associated with difficult reduction of proximal fragment leading to apex anterior, valgus or varus malalignment and anterior displacement of the proximal fragment (8),(17),(18),(19),(20). Hence, conventional nails has been replaced by expert tibia nail which is anatomically designed and the multidirectional interlocking screws provides better axial and angular stability to the proximal fragments.

Various previously published studies shed light on the various factors contributing to the sagittal and coronal plane deformities when IMN nailing was used to fix proximal tibia fractures. Factors associated with sagittal plane deformities includes the pull of the patellar tendon (8),(18),(19) and the muscles of the anterior compartment (17), lack of a posterior cortex (17), the “wedge effect” of the bent nail in the distal fragment (20), and a distal starting point for nail insertion (18). Similarly, there are some factors which come into play and leading to coronal plane deformities which includes an inappropriate entry point mainly a more medial entry, inserting nail with the tip directed laterally (8),(17),(18), and the various forces acting due to the pull of muscles of lateral compartment (17). Following are the studies with their outcomes in terms of malalignment, factors contributing to malunion, and various technical modifications undertaken to prevent the malalignment.

Freedman EL and Johnson EE carried out a radiographic evaluation of 133 tibia fractures treated with IMN fixation and reported that 7 (58%) of the 12 proximal tibia fractures were malaligned, compared with an overall rate of 12% in the whole cohort (17). To avoid the coronal plane deformities, they suggested practicing a slight lateral entry point.

Similarly a data shared by Lang GJ et al., reported that 27 of 32 proximal tibia fractures (84%) had an angulation of 5° or more in the frontal or sagittal plane, which were treated by conventional interlock nails and suggested that coronal plane deformities could be prevented by avoiding medial entry point and directing nail laterally (8). In contrast, sagittal plane deformities were avoided by inserting the nail as possible as parallel to the anterior cortex to minimise the extent of anterior angulation.

Tornetta P and Collins E described the use of the semi-extended position of the knee for IMN of fractures of the proximal tibia to avoid sagittal plane deformities (19). The knee was positioned in 15 degrees of flexion during the procedure. Immediate postoperative assessment for alignment was carried out in 30 patients with fractures of the proximal-third of tibia treated with intramedullary nails, found that five patients treated without using the semi-extended knee position had an average flexion deformity of 8 degrees (range 5 to 15 degrees). The remaining 25 patients were treated using the technique described, and it was found that only two patients had malalignment.

Buehler KC et al., described a lateral starting point for nail insertion to avoid the valgus malalignment (18). In order to prevent sagittal plane deformities, they suggested that the entry point should be as proximal as possible and use of femoral distractor was done to nullify the deforming forces of the patellar tendon. In this study, they practiced nailing in hyperflexion with the use of prototype outrigger handles which helped to insert the nail parallel to the anterior cortex of proximal fragment in a sagittal plane. Interlocking was carried out in full extension which helped to fix the fracture in the position of optimal fracture reduction. In this study, 14 patients were operated on by using these techniques and reported that one patient had malalignment and the other one landed up in non union for which revision surgery was carried out.

Hansen M et al., in a study of 181 patients with tibia fracture treated with ETN, found that clinical union was seen in 12.4 weeks after the surgery, and the time for radiological union was 18.2 weeks post surgery (21). He reported that the chances of valgus, varus malalignment of greater than 5 degrees in any plane on radiographic was 4.3% for shaft fracture, 1.5% for intra-articular fracture fractures distally, and 1.3% for intra-articular fracture proximally.

Zhu DC et al., conducted a study of 31 patients, which undergone expert tibia nailing and found that union was achieved in all cases at 17.6±2.5 weeks (22). The duration of surgery was 84.5±17.3 minutes and the time required to achieve union was 8.4±2.1 weeks. 90% of patients show good to excellent results according to Johner-Wruhs’ criteria.

In the present study, it was found that these fractures were four times more commonly found in males than females, with patients belonging to a mean age of 41.8 years, which is comparable to the study conducted by Zhu DC et al., (22). The aim of the study was to study the functional outcome of the modality as mentioned above of treatment. In the majority of cases, the mode of trauma was road traffic accidents followed by fall from height highly suggestive of high-velocity injury. The average time duration required for a surgical procedure was 111.19 minutes. Zhu DC et al., in there study achieved union at 17 weeks which is comparable to present study (22). During the study, it came to the notice that union was achieved relatively earlier in closed fractures than compound fractures. Among these 28 patients, three patients’ union was delayed, which was achieved by doing bone grafting later on. The probable cause of such a prolonged union was due to malalignment and inappropriate implant fixation, which was later corrected during the revision surgery by doing exchange nailing and bone grafting to expedite the healing process. At 12 months of follow-up, the functional outcome of the patients was assessed based on Klemm KW and Borner MA scoring system (15), and according to which out of 28 patients, outcome were excellent in 20 (71.42%), good in 5 (17.85%), fair in 2 (7.14%) and poor in 1 (3.57%) which are almost comparable to a study conducted by Tijoriwala P et al., (3). In this study comparision of functional outcome at six weeks and 12 months was done, and found significant difference (Table/Fig 7).

In present study, semi-extended position of knee was used, to avoid extension of proximal fragment. The rationale of this method is that it eliminates the pull of quadriceps on proximal fragment and allows anterior placement of the nail. After appropriate proximal and distal interlocking of a nail, the blocking k-wires were removed, and no loss of reduction was seen, which is attributed to the use of snuggly fit nail. Even after using these technical, it was noted coronal pane deformities in 6 (21.42%) patients, which was because of wide canal in osteoporotic patients, comminution and inappropriate entry point, reaming and placement of undersized nail. However, these coronal plane deformities were not clinically significant. The incidence of occurring coronal plane deformities is almost similar to the study conducted by Nork SE et al., (11).

The present study malunion rates are much lower compared to the above-mentioned studies (9),(18),(19),(22), which used conventional nails, in contrast to which expert tibia nail allows multidirectional locking options providing better angular stability and also secondary to various modifications made to the techniques of reduction and nailing. The study has shown that nailing is a good option in case of compromised soft tissue status. Nailing has an added advantage in terms of less blood loss, fewer chances of infection, shorter hospital stay, early mobilisation, and rehabilitation. It came to notice that nailing is quite associated with acceptable degree of malalignments with good functional outcome and minimal complications. Thus, making expert tibia nailing an effective modality of treatment for extra-atricular proximal-third tibia fractures.

Limitation(s)

Due to poor socio-economic status of patients in our government setup and non-availability of expert tibia nail through government schemes, small number of cases were performed. Limited period of follow-up as well as comparative analysis with other treatment modalities was necessary to establish the effectiveness of expert tibia nailing in proximal-third tibia fractures was not done. To establish the role of expert tibia nail for treating simple intra-articular fracture also requires further study to find out its efficacy.

Conclusion

From the study, conducted and the results obtained, the functional outcome after treating extra-articular proximal tibia fractures with expert tibia interlock nailing in the majority of the cases is good to excellent. The study concluded that a multidirectional interlocking system and anatomically designed expert tibia nail confers angular stability and provides better hold of fragment in three planes and, thereby allowing the surgeons to address the high proximal tibia fractures. The study has shown that nailing is a good option in case of compromised soft tissue status. Nailing has an added advantage in terms of less blood loss, fewer chances of infection, shorter hospital stay, early mobilisation, and rehabilitation. It came to notice that nailing is quite associated with acceptable degree of malalignments with good functional outcome and minimal complications. Thus, making expert tibia nailing an effective modality of treatment for extra-articular proximal-third tibia fractures.
