Background: The comminuted and/or long subtrochenteric femoral fractures are considered as a difficult fractures to treat. The objective of this study was to evaluate the success rate of dynamic condylar screw fixation for the treatment of these subtrochenteric fractures. Methods: Total 30 consecutive patients of age 21 to 60 years with subtrochenteric fractures were included in our study. The type of fractures were classified according to AO- classification system and the patients were assessed using the Harris hip score. Results: The cases were followed up from 9 to 15 months (mean 12 months). The time required to full weight bearing was 10 to 16 weeks (mean 14 weeks ). No cases were lost to follow up. There were no cases of non-union or infection. There were two cases of implant failure due to early weight bearing and osteoporosis. With the exception of 2 implant failure cases(6.67%) , all the cases in our study had excellent (55. 3%) to good (40.0%) functional outcome. The mean Harris hip score was 86. Conclusions: We came to the conclusion that dynamic condylar screw is valuable and practical method of fixation of subtrochenteric fractures. Minimum soft tissue damage, preservation of medial blood supply, and gentle manipulation of fracture fragments along with proper fixation techniques are of paramount importance to achieve good fracture healing and to avoid complications.
