摘要
膝关节伸直位强直畸形多系下肢骨折或骨髓炎后固定时间过长所致。以往多用股四头肌成形术,但术后可致股四头肌肌力下降、膝关节伸直不良。作者自1988年以来对5例膝关节伸直位强直畸形患者行股前大片带蒂阔筋膜衬垫股直肌深面手术,术中采用“S”状切口。将长约25cm暴露的阔筋膜制成蒂在外侧20cm×15cm的矩形阔筋膜瓣,将游离缘从股直肌深面衬垫至股内侧肌外侧间断缝合数针固定。松解膝关节内外侧粘连,被动屈曲膝关节至120度。术后次日功能锻练,辅以理疗。术后随访8个月至2年,患肢活动范围100度以上,效果满意,无肌力减退、无跛行。
The cause of most extension contracture of knee is injury or osteomyelitis leading to fibrosis and scarring of the quadriceps.Previously quadriceps plasty was usually used,which often resulted in weak extension.Since 1988 five patients were operated on with pediceled fascia lata flap as ped below rectus femoris.Using“S”incision,fascia lata(20cm×15cm)with lateral pedicel was made from fascia lata of 25cm in length,The free edge was padded below rectus femoris,and then sewn up and fixed.The bilateral adhesion of knee was released and knee was passively flexed to 120 degree.Functional exercises as well as physiotherapy was started 24h after operation.All of the patients were followed up from eight months to two years and showed a range over 100 degree without weak extension and lameness.
