卷曲式股方肌骨瓣植骨治疗股骨颈骨折

Curved Musculus Quadratus Femoris Flap with Bone Transplantation to Treat Femoral Neck Fracture

目的增加股方肌骨瓣血运，减少股骨颈骨折术后股骨头坏死及骨折不愈合发生率。方法将传统的股方肌骨瓣宽度由原来1．0-2．5cm扩大至3．5～4．0cm，长度不变，这样骨瓣的骨膜供血可增加1倍以上，再将骨瓣纵向劈开变成数份，每份宽约0．5cm，将劈开的骨瓣卷曲后植入股骨颈骨槽。结果应用卷曲式股方肌骨瓣治疗青壮年股骨颈骨折36例，33例获1-5年随访，尚未发现有股骨头坏死及术后骨折不愈合发生，骨折平均愈合时间为7．2个月，其中优28例，占随访者84．8％；良4例，占随访者12.1％，中1例，占随访者3．1％。结论卷曲式股方肌骨瓣可增加股方肌骨瓣血运，减少股骨颈骨折术后股骨头坏死及骨折不愈合的发生率．

Objective To enhance the blood supply of musculus quadratus femoris （MQF） and reduce the post operative necrosis and disunion rate to treat femoral neck fracture（FNF）. Methods The width of classical flap was increased to 3.5 - 4.0 cm to increase the blood supply and then split into segments with 0.5 cm to curved and transplanted. Results 35 cases of FNF adult patient were treated with this method and 33 cases were followed up 1 - 5 years. There was no post operative necrosis and disunion. The average healing time was 7.2 months. There were 28 cases excellent and 4 cases good effect. Conclusion This method might increase the blood supply so that to decrease the post operative necrosis and disunion rate.
