Chronic spontaneous dislocation of the sternoclavicular joint occurs more frequently in athletes than nonathletes, causing weakness and sometimes pain during prolonged stress upon the arm. Five such joints were successfully treated in 4 patients by means of a dynamic method of repair--tenodesis of the sternal head of the sternomastoid muscle. The sternal origin of the sternomastoid muscle in continuity with its muscle belly and strip of sternal periosteum is looped under the first rib, back through a drill hole in the clavicle and sutured to itself to replace the damaged costoclavicular ligament. Dislocations of the joint should not be repaired for purely cosmetic reasons as the risk of keloid scar formation in this region is notoriously high. All the patients who were young and athletically inclined, recovered fully within 4 months of the operation and returned to their sporting activities. Follow-up has ranged from 12 to 38 months. There have been no late complications or failures of the technique.
慢性自发性胸锁关节脱位在运动员中比非运动员更常见，在长时间手臂用力时会导致虚弱，有时还会疼痛。4例患者的5个此类关节通过一种动态修复方法——胸锁乳突肌胸骨头腱固定术成功得到治疗。胸锁乳突肌的胸骨起点与其肌腹及胸骨骨膜条相连，绕过第一肋下方，再穿过锁骨上的钻孔，然后缝合至自身，以替代受损的肋锁韧带。不应仅出于美容原因修复关节脱位，因为该区域形成瘢痕疙瘩的风险非常高。所有年轻且有运动倾向的患者在术后4个月内完全康复，并恢复了体育活动。随访时间为12至38个月。该技术没有出现晚期并发症或失败情况。
