逆行交锁髓内钉在股骨远端骨折的应用

目的评价股骨逆行交锁髓内钉的治疗效果。方法自2003年7月起,共收治股骨下段骨折患者31例(AO分类A1型8例,A2型16例,A3型7例),行股骨下段骨折开放或闭合复位,逆行交锁髓内钉内固定术,术后随访2～36个月,平均10个月。结果31例中29例获骨性愈合,2例固定术后不足3个月,无法评价,愈合率为93.5%,膝关节功能按Schatzker评分,优15例,良16例,无明显功能丧失。结论逆行股骨交锁髓内钉治疗股骨下段骨折具有并发症少,愈合率高等特点。

Retrograde intramedullary nailing in distal femoral fractures-results in a series of 31 consecutive operations

Objective The purpose of this study was to evaluate the therapeutic efficacy of retrograde intramedullary nailing. Method A series of 31 consecutive patients with 31distal femoral fractures (AO type: type A1 8 cases, type A2 16 cases, type A3 7 cases), who were treated with a retrograde intramedullary nailing. Operational data, per-and post-operative complications and the outcome were studied retrospectively after a mean follow-up of 10 months. Results 29 in the 31 cases achieved bone union, and the final union rate was 93.5%. According to Schatzker Scoring system, functions of knees of 15 cases were excellent, 16 cases were good, and none has evident functional incapacitation.Conclusion The results suggest that the retrograde intramedullary nailing is a reliable alternative in distal femoral fracture treatment with a low complication and high union rate.
