Treatment of locked posterior fracture-dislocations of the shoulder by total shoulder arthroplasty.

Total shoulder arthroplasty is indicated in the treatment of locked posterior fracture-dislocations of the shoulder where there is extensive damage to the articular surfaces of the humerus and glenoid. This report reviews the surgical technique, postoperative rehabilitation program, and functional results of seven shoulders in five patients who had locked posterior dislocations of the shoulder. Activities involving overhead positioning of the arm and heavy lifting continued to be challenging for this group of patients. The American Shoulder and Elbow Surgeons' Shoulder Score improved from 20.1 before surgery to 55.6 after surgery (p = 0.018). The extrication of the posteriorly dislocated humeral head may be difficult from an anterior deltopectoral approach. The authors describe the use of a secondary posterior incision facilitating the extrication of the humeral head. In this series total shoulder arthroplasty reliably decreased the patients' level of pain, improved their range of motion, and significantly improved their level of function.

Treatment of shoulder dislocation with ipsilateral humeral shaft fracture.

A case presentation of shoulder dislocation with ipsilateral humeral shaft fracture is presented along with a review of the literature regarding nine reported cases. In the current case, closed treatment of the humeral shaft fracture was undertaken with an unsuccessful attempt at closed reduction of the anterior shoulder dislocation, resulting in a radial nerve deficit. Successful treatment required open reduction of the humeral fracture with compression plating followed by closed reduction of the shoulder dislocation. We compare this treatment (with outcome) to other methods of treatment.

Ipsilateral dislocation of the shoulder and elbow joints with contralateral comminuted humeral fracture.

Ipsilateral dislocation of the shoulder and elbow joints is a rare and complex injury. During the last 25 years, only 3 cases have been reported in the literature. We report a 50-year-old woman who suffered ipsilateral elbow and shoulder dislocation with contralateral comminuted humeral fracture. Both shoulder and elbow joints were reduced, but the elbow was dislocated subsequently at follow-up. The reduction in the elbow was stabilized by a Kirschner wire that was removed at 3 weeks, and the elbow was then stable. A U-shaped coaptation splint was applied for the contralateral comminuted humeral fracture. At 6 months, she had acquired a nearly full range of motion of both shoulder and elbow with complete healing in the contralateral humerus. Although rare and complex, ipsilateral shoulder and elbow dislocation, which is the result of a high-energy trauma, can be treated conservatively.

Glenohumeral arthrodesis. Operative and long-term functional results.

Seventy-one shoulders of seventy patients were fused for treatment of various conditions, and the results were analyzed after an average follow up of nine years and six months. The operative technique always included the use of internal fixation. The average position of arthrodesis was 45 degrees of abduction and 25 degrees of flexion of the arm, with the flexed forearm rotated 21 degrees above the horizontal plane, measured with the arm abducted and flexed. In sixty-eight shoulders, one operation achieved a solid fusion; in the other three, a second arthrodesis was required. Complications included tenderness over the outer ends of the internal fixation device, which required its removal from seventeen shoulders; a fracture in the fused extremity in ten patients; and a post-operative infection in one. Relief of pain was adequate in three-quarters of the patients. Three-quarters of the patients could perform activities involving reaching the trunk, one-half could do activities requiring reaching the head, and one-quarter were able to do light work with the arm at shoulder level or higher. The position of fusion had little effect on the result. Eighty-two per cent of the entire group believed that they had benefited from the operation, and none of the results deteriorated with time.

[Forensic identification of floating shoulder injury].

OBJECTIVE: To discuss forensic identification of floating shoulder injury (FSI). METHODS: To analyze fifteen cases of FSI which were accepted from Jan. 1993 to Jan. 2006, including 15 shoulder neck fracture, 13 clavide stem fracture and 2 distal end clavide fracture, the function of shoulder joint was evaluated six months after injure considering the following three aspects: result of forensic examination such as X-ray photograph, CT and MRI, the injurers' symptom, objective sign and joint function, shoulder joint territory, degree of pain and local muscle power. RESULTS: Basing on the curative effect standard of Herscovic, all cases were divided into good. Modest, worst, which included 2, 4, 9 cases respectively; referring the standard of GA35-92, GB18667-2002, all cases were divided into six, seven, eight, nine and ten degree, which included 2,9,2,1,1 cases respectively. CONCLUSION: As a special powerful injure, FSI always companied with concurrent and multiple injure, and characterized by missed, incorrect and delayed diagnosis and infelicitous treatment, which lead to the high frequency and degree of injure. To prevent missed and incorrect forensic identification, we should have a full realization of the particularity of FSI, and evaluate the function of shoulder all-sidely, objectively and synseticaly.

Posterior shoulder dislocation associated with fracture of the humeral anatomic neck: treatment guidelines and long-term outcome.

OBJECTIVE: We describe here 10 cases of posterior shoulder dislocation associated with fracture of the humeral anatomic neck. METHODS: Patients were treated according to our uniform treatment guidelines, in which only the dislocated humeral head (closed, if possible) was reduced, without any concomitant repositioning or internal fixation for fractures. RESULTS: Reduction resulted in an acceptable repositioning of the fractured fragments in all but one case. Anatomic neck fractures were impacted by applying longitudinal pressure for stabilization. Although early physiotherapy was initiated, redisplacement of the bone fragments did not occur. Of nine patients who were followed for more than 2 years, complete recovery of function was achieved in all but two patients. The completely detached humeral head became avascular necrotic accompanied by subchondral collapse in one case, and in the other case the displaced lesser tuberosity caused a decreased range of movement. CONCLUSION: We recommend initially treating such patients by either open or closed reduction of the dislocated humeral head and impaction of the fracture, with neither repositioning nor internal fixation of any of the fractured fragments. A completely detached humeral head or bone fragments displaced more than 10 mm after reduction of the dislocated humeral head contraindicate the use of this method.
