PURPOSE To evaluate the clinical and radiological result of surgical treatment of acromioclavicular joint dislocation, using modified Phemister technique with tension band wiring. MATERIALS AND METHODS We chose 17 patients who were able to follow up 1 year or more among the patients who were diagnosed as acromioclavicular joint dislocation in our hospital through January 2000 to Feburary 2005 and took modified Phemister technique with tension band wiring. Evaluation of the surgical results was done with the condition of pain, activity of daily living, range of motion, muscle tone by constant score system, and with preoperative, postoperative and last follow up radiographs. RESULTS Clinical evaluation was average 92 point by Constant score system from 84 point to 100 point. Subjective evaluation was 11 excellent (65%), 6 good (35%). Radiological evaluation was 9 excellent (54%), 6 good (38%), 2 fair (12%), and no poor group. On the final follow up, two cases showed inflammatory reaction at where pins were inserted, but after the removal of the pins, the inflammation was subsided. CONCLUSION The modified Phemister surgery for acromioclavicular dislocation is one of effective techniques, we can obtain firm fixation, exercise full range of motion early and there is no complication of re-dislocation.

PURPOSE To evaluate the follow-up result of 11 cases that were operated with internal fixation of scapular neck and internal fixation of clavicle or acromioclavicular dislocation for severely displaced floating shoulder which was high energy injury and unstable. MATERIALS AND METHODS We examined the scapular neck fracture with clavicle fracture or acromioclavicular joint dislocation by multidisciplinary research from August 1997 to July 2004. The scapular neck fractures were operated in the case of translational displacement of more than 25 mm and angular displacement of more than 45 degrees with 3.5 mm reconstruction plate fixation and internal fixation for clavicle fracture or acromioclavicular joint perpormed simultaneously. And we evaluated 11 cases that can be followed up for more than 9 months. RESULTS We achieved bony union in all cases. In ASES functional score, we got average 89.2 (75~95) points. In Rowe functional score, we got average 89.1 (75~100) points. In complication, there was external rotation weakness in 1 case. CONCLUSION In severely displaced floating shoulder due to high energy injury, we got good clinical and functional result after internal fixation for scapular neck and clavicle or acromioclavicular joint.
There are various kinds of operative methods for the treatment of acute acromioclavicular dislocation but many complications such as posttraumatic arthritis, limitation of shoulder motion, and recurrence of dislocation would be developed.
We have experienced 23 cases of acute acromioclavicular dislocation treated by modified Phemister technique from January 1992 to January 1997 and followed-up at least 1 year at Department of Orthopaedic Surgery, Pusan City Medical Center.
The results were as follows: 1. The clinical results were evaluated by Weaver and Dunn were good in 19 cases, fair in 3 cases, poor in 1 case.
2. The radiological results were evaluated by the difference of the distance from the coracoid process to the clavicle between normal and injured site. The comparison of coraco-clavicular distance after surgery(1.76 mm) with that of follow up(2.41 mm) showed no significant difference(P>0.05, by Student t-test).
3. There was no posttraumatic arthritis and limitation of shoulder motion in all cases. So we suggest that modified Phemister technique is a good method for aute acromioclavicular dislocation.
There are many procedures for the treatment of acute A-C injury which have many complic ation such as limitation of shoulder motion, post traumatic arthritis and recurrence of dislocation etc. From July 1992 to June 1996 at National Medical Center, 21 patients with A-C injury had been treated by modified Phemister operation. The mean follow up time was 14.6 months.
The following results are obtained. 1. There was no limitation of shoulder motion in 20 cases. 2. The comparison of coraco-clavicular distance after surgery ( 2.24 mm ) with that of fallow up ( 3.95 mm ) showed no significant difference. 3. Clinical resuls showed that good in 18 cases, fair in 2 cases, poor in 1 case. From the above result, we suggest that Modified Phemister method is simple and good procedure in the treatment of acute A-C dislocation.
Acoromioclavicular dislocation occurs frequently in young athletes and recently in automobile accident victims and laborers, and there are various kinds of operative methods for this injury. Authors performed operative treatment for 45 cases of acromioclavicular dislocation: 30 cases of modified Phemister operation and 15 cases of modified Bosworth operation from March 1992 to June 1996. Authors analysed the result of the treatment and the results obtained were as follows.
1. The clinical results evaluated by Weitzman criteria were all satisfactory in both modified Phemister method and modified Bosworth method.
2. The radiologic results were evaluated by the difference of the distance from the coracoid process to the clavicle between the normal and the injured site. And the result was more satisfactory in modified Bosworth method.
3. There were less complications in modified Bosworth method.
There has been considerable controversy as to the method of treatment of acromioclavicular joint especially in grade III injury. We treated 27 cases of the complete dislocation of acromioclavicular dislocation with operative method(15 cases) and conservative method(12 cases) from October 1989 to November 1995. The purpose of this study is to compare the clinical and radiological result of two treatment method. The average follow up period was thirty nine months and the result as follows.
1. Of the 27 cases, there was 18 male and 9 female patients, and peak incidence was in 3rd and 4th decades(51%).
2. The most common causes of the injury was traffic atcident(49%).
3. The functional results were similiar to all treatment modalities, and coracoclavicular interval ratio was well manintained regardless of treatment.
4. Complication rate was more lower in the group of conservative treatment.
5. The conservative treatment was proven to be a valuable method for acromioclavicular dis- location except in a few situations.
Acromioclavicular dislocation with a concomitant coracoid process fracture occurs infrequently, as only several cases have been reported in the literature. This injury usually occurs in the second or third decade of life. The mechanism of injury were sports, motor vehicle and direct trauma.
An axillary lateral radiograph of the shoulder often is needed to detect this fracture.
The authors present two cases of coracoid process fracture associated with acromioclavicular dislocation. Satisfactory function with minimal residual cosmetic deformity may be achieved by nonoperative measures. Also surgical treatment can produce good result in complete third acromioclavicular separation combined with the significantly displaced coracoid fracture.
