The purpose of this study was to report the surgical results of a distal clavicle resection. Eight patients (six male, two female) underwent surgical treatment Their mean age was thirty-seven years old. The current disease contained 4osteoarthroses,2 acromio-clavicular separations, a fracture of the distal end, and a post-traumatic osteolysis. The mean follow-up period was seven months. Pain, muscle strength, and range of motion were, assessed using the modified JOA shoulder scoring system. The impingement phenomenon, instability of the gleno-humeral joint and a complication were evaluated. The modified JOA score postoperatively deteriorated in two female patients. The outcomes of the JOA scores became better in six patients. Their gleno-humeral joints were not clinically unstable in any of the patient. Two of eight patients had numbness, a cold sensation and pain of the upper extremity on the surgical side. The upper extremity was bony connected to the trunk only via the acromio-clavicular joint. In cases with the distal clavicle resection, the scapulothracic joint was only stabilized by surrounding muscles and coraco-clavicular ligament Among patients with muscle insufficiency around the scapula, thoracic outlet syndrome might occurr postoperatively.
