Background and objectives: Subtrochanteric fractures are sustained by elderly from trivial trauma such as slipping on stairs, or in the toilet, in younger patients they are caused due to high energy injuries. These fractures are complicated by mal-union, delayed union, non-union. Only recently understanding of biology, reduction techniques and biomechanically improved implants like Gamma nail, Russell-Taylor’s nail, Proximal femoral nail allowed for these fractures to be addressed with consistent success. This led us to study sub trochanteric fracture fixation with Dynamic hip screw system (DHS) and cephalomedullary nail. Materials and methods: Study consists of 40 patients of traumatic sub trochanteric fractures of femur, of which 20 patients are treated with DHS system and remaining 20 are treated with cephalomedullary nail. Results: Mean time of bone union with DHS group was 19.8 weeks and with nail was 15.2 weeks. According to Kyle’s criteria 30% patients were treated with DHS and 50% of patients were treated with nail showed excellent results. Good results were 50% in DHS and 40% in nail, Fair results 20% in DHS and 10% in nail. None of the patients showed poor results. Interpretation and Conclusion: Cases treated with cephalomedullary nail have shown minimal blood loss, early rehabilitation, early rate of fracture union as compared with those cases treated with DHS as per our study.

A retrospective study of sub trochanteric fractures of femur managed with dynamic hip screw system and cephalomedullary nail
