biological plating in comminuted subtrochanteric fractures

Background: Comminuted subtrochanteric fractures have been a challenge for orthopedic surgeons in terms of appropriate reduction and stable fixation. Numerous methods have been used for the fixation of comminuted subtrochanteric fractures among which some are accompanied with technical difficulties and complications of their own. Regarding the results of previous studies, we decided to evaluate the biological fixation method in comminuted subtrochanteric fractures. Methods: In this prospective study, we evaluated 20 men with comminuted subtrochanteric femoral fractures. The patients underwent indirect reduction with dynamic hip screw (DHS) or dynamic condylar screw (DCS) fixation within one week of injury. The patients were evaluated clinically for pain, hip and knee range of motion, leg-length discrepancy and angular and rotational deformities, in addition the radiographic assessment of the ::::union::::. Results: According to Seinsheimer's classification of subtrochanteric fractures, four patients had type III, nine had type IV and seven had type V fractures. Fracture fixation was performed by DCS in eight and by DHS in 12 cases. The average time of the operations was 79.4 (ranging from 60-125) minutes. Mean blood loss was 634 (ranging from 340-1160) milliliters. Uneventfully, ::::union:::: occurred in all patients with no clinical pain or dysfunction. Conclusion: Submuscular plating with either DCS or DHS is a viable option to treat comminuted subtrochanteric fractures. The results of this study highly suggest use of submuscular plating in the treatment of comminuted subtrochanteric fractures, especially in the third world countries.
