A prospective study to compare functional outcome of Dyanamic Hip screw versus Proximal femoral nail in treatment of intertrochanteric fracture of femure

Background: Trochanteric fractures account for approximately half of the hip fractures in elderly; out of this, more than 50% fractures are unstable. The choice between extra medullary or intramedullary devices for pertrochanteric fracture treatment among surgeons remains controversial and significant variation in surgeons' device choice for trochanteric fractures exists. Hence, the objective of the present study was to compare functional outcome of Dyanamic Hip screw versus Proximal femoral nail in treatment of intertrochanteri fracture of femure. Material and Methods: A total sample size of 30 patients with unstable trochanteric fractures and treated by either extramedullary or intramedullary internal fixation between July 2015 to June 2016 were included in the study. The study patients for operative procedure were randomly selected into two groups by surgeon's preference. The patients were then assessed clinically to evaluate their general condition and the local injury. The functional outcome of both the methods was evaluated by Harris Hip Score. Results: Majority of the patients were in the age group of 60-70 years i.e. in Group A (53.3%) and Group B (66.7%). Majority of patients were male in both groups. Nineteen (63.3%) had a history of road traffic injury (RTI). In group A, 9 (60%) patients and in Group B, 10 (66.7%) patients had RTI. The functional outcome in both the groups showed no statistical significance. (P>0.05) Conclusion: The intramedullary device can be used effectively to treat unstable trochanteric fractures and may be the best choice particularly in unstable trochanteric fractures because of its low re-operation rate.
