The most common odontogenic tumours are odontomas, they account for 22% of them, but there apparent eruption into oral cavity is rare. We report a rare case of erupting complex odontoma coronal to impacted second molar associated with dentigerous cyst.

BACKGROUNDTotal hip arthroplasty is one of the most successful procedures introduced in twentieth century. In this study, we compared total hip arthroplasty with mini incision (modified posterior) and standard posterior approach. MATERIALS AND METHODSTotal of 96 hips were studied, 48 hips in mini incision group and 48 hips in control group. 84 patients were selected with primary total hip arthroplasty performed on a total of 96 hips during a period of June 2012 to September 2014. Out of 96 hips, 66 hips were avascular necrosis of head of femur, 3 rheumatoid arthritis, 9 ankylosing spondylitis, 3 central dislocation, 3 fracture neck of femur with broken SP nail. 48 hips were operated with mini incision and 48 hips operated with standard incision. Average age of the patients is 56 years in standard incision group and 47 years in mini incision group. Harris hip evaluation (modified) was used for recording the status of hip before surgery and postoperative results. The patients were compared with respect to the length of incision, surgical time, blood loss, acetabular cup placement, femoral stem placement, and complications. Radiological parameters included were abduction angle, stem alignment, and quality of cement mantle. Average follow up was 12 months. Patients were followed up in OPD for regular examination in three monthly intervals and functional assessment of the hip was done using the Harris hip score (modified). RESULTSThinner, healthier, and younger patient were included in mini incision group as compared to the control group. The final outcome was to be statistically insignificant expect surgical time and blood loss and cosmetically. 95% of the patients had excellent to good functional result in mini incision group and 100% had good result in standard incision group. In our series, 6 patients had intraoperative hypotension in standard group due to excessive blood loss. 3 patient had stitch abscess, which healed during subsequent dressing, 3 patient had peroneal nerve palsy, and 6 patients had dislocation in mini incision group. CONCLUSIONOur study defies most of benefits of mini incision technique. However, no improvements were seen in any of the parameters studied. Long-term studies are required to investigate the impact of the use of minimally invasive approach on the durability of replacements.

INTRODUCTION Most of these fractures except intra-articular fractures are treated with interlocking nail. 1,2 These nails are a boon for these fractures. But as the fracture nears to the joint stability the fracture fixation will be compromised due to malreduction and alignment, it leads to increased chances of delayed and nonunion. 3 Locking anatomical plates are evaluated for anatomical and relative stability fixation. Since then most intra and near intra-articular fractures are fixed with these plates with minimally invasive percutaneous plate osteosynthesis method, these plates have given excellent result 4. But again these plates have some disadvantages 5. This study is done to see the outcome of locking plates in distal tibia fracture. METHODS This study is done in the Department of Orthopaedics, Bangalore Medical College, Bangalore. This study is done from 2013 to 2015. 30 patients who came to outpatient department were treated with locking plates. All patients above 16 years having distal third tibia fracture are included. All open fractures except type 1 and elderly above 60 years and pathological fractures are excluded in our study. All patients were followed up for initial 5 months, thereafter, once in 3 months, for clinical and radiological evaluation of union status, knee range of motion, ankle range of motion and other complications. Assessment of the patient with functional recovery was done with American Orthopaedic Foot and Ankle Surgery(AOFAS) 6 minimum 5 months after injury. RESULTS Majority of the patients are from age group 18-29 years (50%). Average age group was 30 years. Majority of the patients were males 80.6% (25). All fractures were closed fractures except 2 cases which are type 1. There were 12 cases of AO type A, 8 patients were AO type B and 10 patients were type C. Majority of the patients had fracture due to road traffic accidents, 74%. All fractures were united by the end of 20 weeks. There was delayed union in (22%) 4 patients for which secondary surgery with bone grafting procedure was done after 4 months. According to AOFAS, 7 we scored the functional outcome of the patients after 5 months of injury. We had 23% of excellent result, 30.4% good and 46% fair with plate. CONCLUSION Locking anatomical plates are a boon and have started a new era in orthopaedic surgery in fixation with articular fractures. But due to lack of locking plate principle it is again cumbersome. Locking plates give relative stability for fracture and need as much as possible anatomical reduction of articular margins unlike in nail where we can do dynamisation if fracture going for delayed union in locking plates is not possible, hence doing as much as possible fracture alignment and then stabilising the fracture with screws is recommended.

Introduction: The trochanteric femur fracture are relatively common injuries. The most important goal of operative treatment is strong, stable fixation of the fracture fragment. Osteoporosis and severe communition makes fixation difficult with conventional methods leading to complications like varus malunion, implant failure and shortening. Proximal femoral nail has its own complication like screw backout, cut through etc. Hence we conducted a study to evaluate the outcome of proximal femoral locking compression plate. Materials: A prospective study of 40 cases of trochanter femur fracture from 2011 and 2017 treated with proximal femoral locking compression plate (PFLCP) was done. Patients were followed up at 1month, 3 month, 6month, 1 year and 2 year, Results were evaluated using Harris Hip Score and radiological union. Results: All the fractures united at final follow up, radiological union was noted at 16 weeks in 31 patients (76%) and remaining 9 patients showed radiological union at 20 weeks (24%). Out of 40 patients in our study 38 had normal union with only 2 patient had union in varus. No valgus deformity noted in our series. In all 40 cases there was no non-union, avascular necrosis or secondary osteoarthritis noted. In our study, 19 patients had excellent results, 15 patients had good results, 4 patients had poor result according to Harris Hip score. Conclusion:The procedure offers, faster mobilization, rapid return to activities of daily living, improves the quality of life and gave a long term solution in patients with trochanteric fracture of femur.
