膝关节镜下股骨髁上交锁髓内钉治疗股骨髁上骨折

Treatment of supracondylar femoral fracture by supracondylar locked intramedullary nail under arthroscopy

目的 评价膝关节镜下股骨髁上交锁髓内钉 (简称GSH钉 )固定股骨髁上骨折的效果。 方法 行小切口开放复位后在关节镜监视下经皮逆行击入GSH钉固定治疗 16例股骨髁上骨折。 结果 所有骨折均在 3月内达骨性愈合 ,随访6月～ 18月 ,膝关节屈曲均达 110°以上。 结论 膝关节镜下GSH钉固定股骨髁上骨折不需切开膝关节 ,不需外固定 ,对关节功能影响小 ,是治疗股骨髁上骨折的一种损伤小、固定可靠、恢复快的新方法。

Objective To evaluate the clinical value of application of supracondylar locked intramedullary nail under arthroscope for supracondylar femoral fractures. Methods Sixteen patients with supracondylar femoral fracture were treated by supracondylar locked intramedullary nail. After mini-incision open reductions were completed, the nails were inserted retrogradely into femoral intercondylar notch under arthroscope. Results Bony union was obtained in all the patients within 3 months. Follow-up for 6～18 months showed ranges of motion (ROM) of their knee joints were 110°or above. Conclusions Application of this nail for supracondylar femoral fracture is characterized by mini-invasion, reliability and rapid recovery. There is no need for traditional open operations on the knee joint, and no need for external fixation.
