腹外斜肌—前1/2腹直肌—阔筋膜张肌联合重建屈髋伸膝功能

Muscles transfer restore functions of flexion of hip and extension of knee

本文报告了对4例连枷腿片腹肌肌力减弱的患者行腹外斜肌—前1/2腹直肌—阔筋膜张肌联合重建屈髋伸膝功能,效果满意。该术式原动力为三肌肌力的几何和,使原动力明显增加;弥补了腹肌肌力减弱的缺陷。在切取腹直肌时,改成取前1/2,留后1/2不动;这样不减少其冠状面覆盖面积,当向外下方牵拉时,便和后1/2腹直肌构成交迭状协同方向,可增强腹壁力量。避免了腹直肌在同一矢状面被分开,当向外下方牵拉时下腹壁形成薄弱间隙。近期随访证明:该术具有一定的特点和临床应用价值,是治疗连枷腿并腹肌肌力减弱患者的新的有效方法;值得提倡。

4 cases with flail leg and weakness of abdominal muscular forces were restored functions flexion of hip and extensiou of knee by combined muscles transferring of the musculi obliques externus abdominis, the anterior half musculi rectus abdominis and fasciae latae, which would increase motive power greatly by the geometry sum of the three muscular forces to remedy the weakness of abdominal muscular forces. All have a good or excellent result. The anterior half musculi rectus abdominis were incised and transferred downward, which interweave with the later half fibre of musculi rectus abdominis that was to increase the power of abdominal wall retained and avoid weakness of the inferior abdominal wall. Follow-up Showed it is a new and effective method to treat patients with flail leg and weakness of abdominal muscular force.
