外固定器固定结合骨膜骨瓣转移治疗尺骨不连接

Fixators and the transposition of perioteal bone flap repair non union in ulna

目的 为尺骨中上段骨不连接的治疗提供一种改进术式。 方法 从血液供应与生物力学两方面 ,设计以骨间返动脉为蒂的尺骨上段骨膜骨瓣 ,转移植骨结合外固定 ,器固定治疗骨不连接。 结果 经采用该术式治疗尺骨中、上段骨不连 12例 ,均取得良好疗效。 结论 骨间返动脉骨膜骨瓣 ,解剖恒定、血供可靠、不损伤主要血管 ,骨外固定器创伤微小、固定牢固、操作简便 ,且可早期功能锻炼 ,防止关节僵硬 ,骨折端有生理应力刺激 ,两者结合从多方面促进骨折愈合 。

Objective This article provides a reform operative method for repairing non union in proximal or middle ulna Methods According to anatomical stady of recurrent interosseous artery from both blood supply and biology strength designs the transposition of proximal ulna periosteal bone flap, combining external fixator to repair non union in ulna Results Twelve cases of non union in proximal or middle ulna were treated by this means, these results were encouraging Conclusions Periosteal bone flap based on recurrent interosseous artery has a stable position, reliable blood supply and no injuring main vessel Moreover external fixator has many advanture, such as steady fixation, rarely damage, simply operation, function train early to prevent producing stiff joint, activate fracture with physiological force, Both can prompt the healing of fracture, It is an efficient method to cure non union in proximal or middle ulna
