摘要

A prospective, randomised, controlled trial was performed to compare the outcome of treatment of unstable trochanteric fractures with either a short proximal femoral nail antirotation (PFNA) or dynamic hip screw (DHS). Eighty one patients with unstable fracture of the proximal part of the femur were randomised, at the time of admission, for fixation with either a short PFNA (n=42) or DHS (n= 39). The primary outcome measure was reoperation within the first postoperative year and mortality at the end of one year. Operative time, fluoroscopy time, blood loss, and any intra-operative complication were recorded for each patient. Clinical and radiological follow-up was undertaken for a minimum of 36 months. Any changes in the position of the implant or fixation failure were recorded. Hip range of motion, pain in the hip or thigh and return to work were used to compare the outcomes. There was no significant difference between 1 year mortality rates for the two groups. The mean operative time was significantly less in PFNA group (25 min) than in the DHS group (38 min). Patients treated with a PFNA experienced a shorter fluoroscopy time and less blood loss. Six patients in DHS group had implant failure while none experienced this in PFNA group. The PFNA group had a better functional outcome than the DHS group.
