钢板髓外固定与髓内钉固定治疗股骨转子下骨折的比较研究

Comparative study of plate external fixation with intramedullary fixation in the treatment of femoral trochanter fracture

目的比较微创内固定系统(LISS)钢板髓外固定与髓内钉固定治疗股骨转子下骨折的手术方法与疗效。方法回顾性分析32例股骨转子下骨折患者资料,根据患者内固定方式分成髓内钉组(18例)和钢板组(14例),比较两组患者手术时间、出血量、骨愈合时间及Harris评分情况。结果髓内钉固定患者的出血量、骨愈合时间均明显少于LISS固定患者,差异有统计学意义(t分别=2.61、2.12,P均<0.05),且髓内钉固定患者6个月后Harris评分亦明显优于LISS固定患者,差异有统计学意义(χ2=4.23,P<0.05)。结论在治疗转子下骨折患者中,髓内钉固定的疗效可能优于LISS钢板固定。

Objective To compare the operation method and curative effect of the LISS plate external fixation with intramedullary fixation in the treatment of femoral trochanter fracture. Methods Retrospectively analyzed the data of 32 patients with femoral trochanter fracture. According to the fixation method, patients were divided into the intramedullary group（18 cases） and LISS group（14 cases）. The operation time, blood loss, bone healing time and the Harris score were compared between the two groups. Results The blood loss was significantly less and bone healing time was shorter in the intramedullary group than those in the LISS group（t =2.61,2.12,P 〈0.05）. The Harris score of patients after 6 months treatment was also significantly better in the intramedullary group than that in the LISS group（χ^2=4.23,P〈0.05）. Conclusion For patients with femoral trochanter fracture, the curative effect of intramedullary fixation may be superior to the LISS plate external fixation.
