Congenital pseudarthrosis of the clavicle, as observed in a review of the literature, is a rare condition of uncertain etiology which usually presents on the right side. Four of 10 cases were treated by surgical repair of the pseudarthrosis with excision of the non-union and internal fixation with a Steinmann pin and cancellous bone graft. A major postoperative complication in one case consisted of an acute massive neuropraxia of the brachial plexus (recognized 6 hours postoperatively), and was successfully treated by immediate removal of the internal fixation. Ten months postoperatively, the patient was experiencing only minimal weakness of the right opponens muscle. Roentgenograms at this time showed that the pseudarthrosis had healed but with angulation of the clavicle.
根据文献综述，先天性锁骨假关节是一种病因不明的罕见病症，通常出现在右侧。10例病例中有4例接受了假关节手术修复，切除骨不连并使用斯氏针和松质骨移植进行内固定。1例主要术后并发症为臂丛神经急性严重失用症（术后6小时确诊），通过立即取出内固定成功治疗。术后10个月，患者仅右侧对掌肌有轻微无力。此时的X线片显示假关节已愈合，但锁骨有角度。
