瘫痪性前臂旋后畸形发生于臂丛上干损伤、脊髓灰质炎和创伤性四肢瘫。其成因是主动的旋后肌与瘫痪的旋前肌肌力恢复的不平衡。一旦畸形固定,桡尺骨弓状畸形将引起远端尺骨和(或)近端桡骨头掌侧半脱位。目前最常用的手术方法之一为肱二头肌止点改道并作骨间膜松解,但该手术不适用于肱三头肌瘫痪和桡骨头已切除的病例。该文作者介绍肱桡肌肌腱改道联合骨间膜松解手术,
Paralyzed forearm pronation deformity occurs in the brachial plexus injury, poliomyelitis and traumatic quadriplegia. The cause is the imbalance in the recovery of the muscular strength of the active supinationis and paralytic pronator. Once deformity fixed, radial ulna arch deformity will cause the distal ulna and (or) the proximal radial head palm side subluxation. Currently, one of the most common surgical procedures is to divert the biceps only and to make the interosseous membrane release. However, the procedure is not suitable for cases of triceps paraplegia and radial head resection. The author introduced the brachioradialorium tendon diversion combined with interosseous membrane release surgery,
