The superior shoulder suspensory complex is composed of glenoid fossa, coracoid process, coracoclavicular ligament, distal clavicle, acromioclavicular ligament, acromion. Traumatic double disruptions of this complex lose its suspensory action on the shoulder joint and result in functional loss and deformity. Careful radiologic evaluation and appropriate management are required for injuries to this complex. Ipsilateral fractures of clavicle and scapula create unstable anatomic situation on shoulder joint. Conservative treatment usually fails to achieve good functional recovery due to rotator cuff weakness, nonunion, delayed union, malunion and neurovascular injury. Authors studied the result of operative treatment of ipsilateral clavicle and scapular fractures to prevent such complications. Seven cases were treated with open reduction and internal fixations of clavicle alone or clavicle and scapula simultaneously and followed up for nineteen months(twelve months - thirty-eight months). All but one patient showed good or excellent functional result according to the scoring system of Rowe. Poor result was developed in the case which had brain injury. Rigid fixations of clavicle alone or clavicle and scapular fractures both can achieve stable reduction of the fractures and prevent sequelae. We concluded that operative treatment of ipsilateral fractures of clavicle and scapula is safe and yields predictable good results.

The arthroscopic bony procedures during rotator cuff repair include acromioplasty, distal clavicle resection, footprint preparation and coracoplasty. The indication of each bony procedure is based on the theoretical reasons, and various types of surgical techniques are available. The purpose of this review article is to review the backgrounds of the indication and surgical techniques in the arthroscopic bony procedures during rotator cuff repair.

Purpose: The purpose of this study is to compare the clinical and radiological outcomes of two surgical treatments, transacromial pin fixation and hook plate fixation, for unstable distal clavicle fractures. Materials and Methods: Twenty four patients with Neer type II distal clavicle fractures who underwent surgery with transacromial pin fixation (Group I: 12 patients) and hook plate fixation (Group II: 12 patients) were included. Reduction and union were evaluated using plain radiographs. Functional evaluation was performed according to UCLA score and Constant-Murley score at last follow-up. Results: All 24 cases showed bone union. Complete union took an average of 10 weeks for group I and 11.7 weeks for group II. Average UCLA score was 33 (group I) and 32.8 (group II). Average Constant score was 88.5 (group I) and 88.8 (group II). No significant difference for each variable was observed between the two groups. Conclusion: For the surgical treatment of Neer type II distal clavicle fractures, transacromial pin fixation and hook plate fixation are both useful methods.

Purpose: This study examined the clinical results of the treatment of type 2 distal clavicle fracture with using a Wolter plate. Materials and Methods: Between 2004 and 2007, 16 patient treated for type 2 distal clavicle fracture using a Wolter plate were included in this study. Their average age was 32.6 years and the postoperative mean follow-up period was 22.9 months. The reduction and union were qualified according to the immediate post-operative and final radiographs. The functional outcome was evaluated by Kona's system and the Constant score Results: By Kona's functional evaluation, there were 12 cases with excellent results, 3 cases with good results and 1 case of fair results and the average Constant score was 90. All 16 cases showed bony union. As complications, there was 1 case in which the protruded hook of the plate could be palpated at the skin, and 1 case showed an acromial fracture, but all the cases dispalyed successful bony union and there was no acromioclavicular joint arthritis, infection or any other complications. Conclusion: Wolter plate fixation for type 2 distal clavicle fracture is a reliable surgical method for satisfactory reduction and rigid fixation, a lower incidence of nonunion and excellent clinical result.

Purpose: To evaluate and report the clinical and radiological outcomes of open reduction and internal fixation with a mini-T plate for unstable distal clavicle fractures. Materials and Methods: From December 2004 to July 2007, fifteen patients who had a fracture of the distal clavicle (Neer type II fracture) were treated with an open reduction and internal fixation using a mini-T plate. They were followed up for a minimum of one year and the clinical and radiological results were analyzed. Results: The average time to fracture union was 3.1(3~4) months. There were no complications, such as deep infection or fixation loss. The mean ASES score was 97 points (85~100points) at the last follow up period, and 14 patients had a full range of motion of the shoulder. Conclusion: Open reduction and internal fixation with a mini-T plate for unstable distal clavicle fracture is a good surgical method with good clinical and radiological results.

Purpose: To review the clinical and radiological results after an open reduction and internal fixation with a T-shaped LCP for unstable distal clavicle fractures. Materials and Methods: From February 2005 to June 2006, ten patients with distal clavicle Neer type II fractures were treated with an open reduction and internal fixation with a T-shaped LCP. Bony union was identified by plain radiography. The clinical results were analyzed according to the UCLA scoring system. Results: The mean time to fracture union was 9weeks and union was achieved in all cases. The mean UCLA score was 33.4 (30-35); excellent in 8 cases and good in 2 cases. In one case, loosening of one distal screw was occured and mild AC joint subluxation was observed in another case. Conclusion: 3.5 mm T-shaped LCP fixation is a useful technique for treating unstable distal clavicle fractures. This procedure provide stable fixation with no further AC joint injury.

Purpose : To evaluate effectiveness of arthroscopic distal clavicle resection for chronic stage 2 acromioclavicular dislocation. Material: 6 patients who had failed to respond to physical therapy were evaluate more than 6 months prospectively, which were treated with arthroscopic distal clavicular resection from february 1998 to January 2001. Result : The median preoperative Constant score changed from 32 of 100 to 37 of 100 at 3 to 6 weeks, to 49 of 100 at 3 months and to 69 of 100 at 6months. Improvement was achived at mean follow up more than 6 months after surgery. Overal $83\%$ of patient were satisfied with this procedure. but the remained case was unsatisfied because symptom was not improved more than 6 months Conclusion : Arthroscopic distal clavicle resection is useful method to treatment for chronic stage 2 acromioclavicular dislocation.
