Unstable trochanteric fracture, Proximal femoral nail, Dynamic hip screw


Background: Treatment of unstable trochanteric fracture is much more challenging than stable fracture. These fractures require stable fixation to minimize the fracture and implant related complications. Need of this study is to assess the suitable implant for stable fixation of unstable trochanteric fracture with less intra and postoperative complications and good functional outcome.

Methods: In this prospective randomized comparative study, 64 patients were distributed into two groups. Group A consisted of patients treated by proximal femoral nail (PFN) (n=32) and group B treated by dynamic hip screw (DHS) (n=32). All the patients were evaluated preoperatively and surgery was done according to the group they were allotted. Post-operative follow up was done at 6 weeks, 3, 6 and 12 months.

Results: Average age of the patients in this study was 51.26±10.24 year. In this study patients were followed up for an average of 10.87±2.61 month. The duration of surgery was shorter in PFN group. Weight bearing was earlier in PFN group than DHS group. Mean functional ability score was better in PFN group with significant gain in function earlier as compared to DHS group.

Conclusions: PFN is a better implant for internal fixation of unstable trochanteric fractures which allows early mobilization and has got better functional outcome score in early postoperative period than DHS
