Evaluation of functional outcome of subtrochantric fracture of femur managed by proximal femoral nail: A prospective study

Abstract

Background: Subtrochantric region is cortical in nature and vascularity is slow so healing is not as fast as highly vascular area of bone. This area of femur is subjected to stress due to its muscular insertions. So there is greater chance of fixation failure, non-union, and failure of procedure. Keeping all these in view present study has been designed to study the anatomical and functional outcome of subtrochantric fracture treated with proximal femoral nail, to access the stability of fixation and mobility of the patients and compare the result with standard treatment. Method: Patients with sub trochanteric facture admitted in the department of orthopaedics and trauma are enrolled for this study based on inclusion and inclusion criteria. Standard operative procedure was followed management of subtrochantric fracture by proximal femoral nail. Demographic, intra-operative, post-operative variavles are recorded. Result: The duration of surgery was 95.636 + 16799 minutes in present study. The mean volume of blood lost during surgery was 114.387 + 17.90 ml and regarding complication of in intra operative period 12% patient required open reduction. Regarding post operative complication no patient were presented with implant failure, malunion and delayed union was present in 10% patients. Joint stiffness and shortening of limb was present in 8% patients. Discussion and Conclusion: We can conclude that subtrochantric fracture is common in elderly and trivial fall is common cause. Intra-operative variables during proximal femoral nailing were good with less blood loss and minimum deformities. Post-operative variables like non union and joint stiffness was less. Most of the patients have good functional out come.
