股骨转子间骨折两种髓内固定方法的比较

目的比较用两种不同的髓内固定方法(Gamma钉和PFN)治疗股骨转子间骨折的临床结果。方法对2000～2003年在我院采用Gamma钉和PFN治疗的205例股骨转子间骨折进行回顾性总结分析,其中116例用Gamma钉治疗,89例用PFN治疗。结果197例患者得到随访,随访12～48个月,平均23.5个月。Gamma钉组:手术时间为68.3min(48～106min),术中失血量为261mL(180～400mL),下地行走时间为5.0周(2.3～8.9周),骨折愈合时间为8.6周(7.1～12.6周);PFN组:手术时间为48.0min(36～85min),术中失血量为192mL(120～360mL),下地行走时间为5.3周(2.5～8.1周),骨折愈合时间为8.8周(6.9～12.1周)。两组在手术时间和术中失血量方面差异有显著性意义(P<0.05)。结论两种髓内固定系统能有效地治疗股骨转子间骨折,但Gamma钉的手术时间和术中失血量较高。

A comparative study of Gamma nail and proximal femoral nail in treatment of intertrochanteric fractures of femur

Objective To compare the clinical results of the intramedullary nails (Gamma nail and the proximal femoral nail) in treatment of intertrochanteric fractures of femur. Methods A review study was conducted on 116 intertrochanteric fractures of femur treated with the Gamma nail and 89 treated with PFN in our hospital between 2000 and 2003. Results In the Gamma nail group, the mean time for operation was 68.3(48 to 106)minutes,the mean blood loss during operation was 261(180 to 400)mL,the mean time for walking after operation was 5.0 (2.3 to 8.9)weeks and the mean time for bone union was 8.6(7.1 to 12.6)weeks. In the PFN group, the mean time for operation was 48.0(36 to 85)minutes, the mean blood loss during operation was 192(120 to 360)mL,the mean time for walking after operation was 5.3(2.5 to 8.1)weeks and the mean time for bone union was 8.8(6.9 to 12.1)weeks. There were significant differences in the mean time for operation and the mean blood loss between the 2 groups(P< 0.05). Conclusion Both the Gamma nail and the PFN are reasonable choices for treatment of the intertrochanteric fractures of femur, but the operation time is longer and the blood loss is more in use of the Gamma nail.
