Objective To compare the efficacy of 90° locking plate of distal femur and Kirschner wire in the treatment of femoral supracondylar fracture in older children.Methods The 61 older children with femoral supracondylar frac-tures were divided into observation group(31 cases were treated with 90° locking plate of distal femur)and control group(30 cases were treated with closed or open reduction Kirschner wire)by random number table.The operation status,pain VAS,fracture healing status and fracture re-displacement rate of the two groups were recorded,and the curative effect was evaluated by Johner-Wruhs criteria.Results All patients were followed up for 6～24 months.Op-eration time and intraoperative fluoroscopy frequency were shorter(less)in observation group than those in control group(P＜0.05).At 1 month after surgery,the pain VAS of the observation group was lower than that of the control group(P＜0.05).The fractures of both groups healed within 3～5 months.At the last follow-up,the observation group was higher than control group in the excellent-good rate of efficacy evaluated with Johner-Wruhs standard(P＜0.05).During the follow-up period,1 patient(3.2％)in the observation group and 8 patients(26.7％)in the control group suffered from re-displacement.The re-displacement rate in the observation group was lower than that in the control group(P＜0.05).Conclusions For treatment of femoral supracondylar fracture in older children,the 90° locking plate of distal femur don't need to shape with firm fixation,and is conformed to biomechanical characteristics,with good effect;and compared with Kirschner wire,the operation time is shorter,the intraoperative fluoroscopy times is fe-wer,the functional exercise can be performed earlier,and the fracture re-displacement rate is lower.
