交锁髓内钉内固定治疗股骨干骨折

Outcomes of closed reduction with interlocking intramedullary nails in treatment of femoral shaft fractures

目的探讨闭合复位交锁髓内钉内固定治疗股骨干骨折的疗效。方法回顾性分析48例股骨干骨折内固定治疗资料。其中,32例使用交锁髓内钉内固定治疗(A组),16例采用传统切开复位(B组)。比较两组疗效。结果 A组获得随访30例,B组15例。A组术中出血量和骨折愈合时间均明显少于B组[(196±54)ml vs.(480±63)ml和(4.5±2.1)个月vs.(5.8±2.9)个月](P<0.05)。A组术后股骨干骨折功能评定优良率高于B组(90.0%vs.86.7%)(P<0.05)。两组手术时间和骨折远端旋转畸形发生情况相仿(P>0.05)。结论应用交锁髓内钉闭合复位治疗股骨干骨折疗效优于传统切开复位。

Objective To evaluate the clinical outcomes of closed reduction with interlocking intramedullary nails in treatment of femoral shaft fractures.Methods Data of 48 cases with femoral shaft fractures treated with interlocking intramedullary nails were retrospectively analyzed,of whom 32 patients underwent close reduction with interlocking intramedullary nails（group A） and 16 patients underwent conventional open reduction（group B）.The outcomes were compared between two groups.Results A total of 32 cases in group A and 16 cases in group B were followed up for averaged 6 months.The blood loss during surgery was less in group A than that in group B [（196±54） ml vs.（480±63） ml]（P0.05）.So did the time of union after operation [（4.5±2.1） months vs.（5.8±2.9） months]（P0.05）.The excellence rate of the joint function after operation was higher in group A than that in group B（90.0% vs.86.7%）（P0.05）.There were no significant differences in operative time and rotational stability after surgery.Conclusion Closed reduction with interlocking intramedullary nail is better than conventional open reduction in treating femoral shaft fractures.
