Purpose Displaced lateral end fracture of clavicle and acromioclavicular dislocation type Ⅲ∼Ⅵ may be required surgical treatment. Material and Methods : From May 1998 to March 2001, we operated with Welter plate with minimal incision by one surgeon. Immediately, pendulum and passive exercise was initiated after surgery. The shoulder function was evaluated using UCLA score. Average follow up was on 28(12∼45) months. Results : All 11 patients were regained satisfactory function. Average UCLA score was 31.9(29~35) at last follow up. Conclusion . The merit of Welter plate fixation with minimal incision is simple technique, reduced surgical time, smaller scar than large plate, strong fixation, early exercise, reduced implant failure. The disadvantage is expensive, skin irritatatation by long hook. But Welter plate fixation with minimal incision is a good method of internal fixation and excellent clinical result in surgical treatment of type H displaced lateral end fracture of the clavicle and type Ⅲ∼Ⅵ acromioclavicular dislocation.

Purpose: Unstable Neer type II lateral end fracture of clavicle may be required operation. The purpose of this study is the effectiveness of the use of Hook plate in the management of unstable Neer type II fractures. We preliminary reported the results of Unstable Neer type II lateral end fracture of clavicle using by Hook plate. Material and Methods: From May 1998 to May 2002, we operated 6 cases unstable Neer type II lateral end fracture of clavicle with Hook plate by one surgeon. We checked radiologic evaluation and disappearance of pain per 1 week, and evaluated improvement of range of motion per 2 week. And we followed up at each interval 3 months,6 months, 12 months and after that per 6months interval, at that each time we checked stress radiogram of shoulder and functional evaluation. The shoulder function was evaluated using Modified Shoulder Rating Scale (MSRC) for Distal Clavicle Fracture and UCLA score. Average follow up was on 37.2 (12∼57) months. Results: All 6 patients were regained satisfactory function. Average MSRC for distal clavicle fracture was 17.3 (15∼20) and average UCLA score was 33.2 (31∼35) at last follow up. Conclusion: There are many advantage of the use of Hook plate on management of unstable Neer II distal clavicle fracture in spite of several disadvantage. There have not yet been reported in our country. So we obtained good to excellent clinical result in surgical treatment of 6 cases on type II displaced lateral end fracture of the clavicle. But we think that more cases will be review and longer follow up will be needed in the future.
