逆行髓内钉与髁部钢板治疗股骨髁部粉碎性骨折的比较

目的比较逆行髓内钉与髁部钢板治疗股骨髁部粉碎性骨折的效果。方法回顾性分析2000-2005年收治的36例股骨髁部粉碎性骨折病例，分别采用逆行髓内钉（n=19）与髁钢板（n=17）两种内固定方法治疗，比较两种方法的骨折愈合时间及膝关节功能恢复情况。结果逆行髓内钉固定股骨髁部粉碎性骨折后，其骨折愈合时间平均为102天，膝关节功能评分为84．59，而踝部钢板固定骨折愈合时间平均为91．35天，膝关节功能评分为91．10，两组比较差异均有统计学意义（P〈0．05）。结论髁钢板对股骨髁部粉碎性骨折的固定效果优于逆行髓内钉。

A comparison of therapeutic effect of retrograde interlocking intramedullary nail and condylar plate fixation in the treatment of comminuted fracture of femoral condyle

Objective To compare the treatment effect of internal fixation with retrograde interlocking intramedullary nails or condylar plates in the treatment of comminuted fracture of the femoral condyle. Methods 36 cases of comminuted fracture of femoral condyle admitted from 2000 to 2005 were treated with retrograde interlocking intramedullary nails (n=19) or condylar plates (n=17). Union time of fracture and the recovery of knee function were observed respectively. Results The average union time of fracture of the cases treated with retrograde interlocking intramedullary nails was 102 days, and the score of knee function was 84.59. Whereas in the cases treated with condylar plates the union time of fracture was 91.35 days, and the score of knee function was 91.10. Significant differences in both union time of fracture and knee function between the two therapeutic methods were observed (P<0.05). Conclusion Condylar plate is superior to retrograde interlocking intramedullary nail in treating comminuted fracture of femoral condyle.
