Modified Phemister Technique with Mersilene Tape Augmentation in the Acute Acromioclavicular Joint Dislocation

PURPOSE: To find out the consequences of the surgical treatment of acromioclavicular joint dislocation, using modified Phemister technique with Mersilene tape augmentation. MATERIALS AND METHODS: We chose 26 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 February 2001 to March 2003 and took modified Phemister surgery with Mersilene tape augmentation. Patients with clavicle fracture were excluded. Evaluation of the surgical results was done with the condition or pain, function, range of motion by using Imatani evaluation system, and preoperative, postoperative and last follow up radiographs. RESULTS: Most of the cases showed satisfactory result. Clinical evaluations were 16 excellent (62%), 10 good (38%), radiological evaluations were 14 excellent (54%), 10 good (38%), 2 fair (8%), and no poor group. On the final follow up six cases showed vertical translation, but none had clinical symptoms. Seven cases showed a little inflammation at where pin were inserted, but after the removal of the pin, the inflammation was gone. CONCLUSION: The modified Phemister surgery for acromioclavicle dislocation is simple, but we can obtain strong fixation, and there is no burden of the removal of the metal plate, or complication of re- dislocation after the removal of the pin, so it is thought as a very effective surgery.

The Comparison of Two Different Fixation Materials In Modified Weaver-Dunn Operation / 대한정형외과학회잡지

PURPOSE: The purpose of this study was to evaluate the usefulness and difference of fixation persistence with two different fixation materials (Mersilene tape and Dall-Miles cable) in modified Weaver-Dunn operation. MATERIALS AND METHODS: Twenty-five cases of acute acromioclavicular dislocation were surgically treated with modified Weaver-Dunn operation, and followed for an average about 15.8 months. For the fixation material, Dall-Miles cable were used in 10 cases, Mersilene tape in 15 cases. Radiological and clinical evaluation were done in all cases. For clinical evaluation, UCLA shoulder function test and ASES score were used. RESULTS: Excellent results were noted in group with Mersilene tape 6 cases and Dall-Miles cable 4 cases, good in 8 cases and 6 cases, and fair in 1 case only Mersilene tape in UCLA shoulder function test. The difference of coracoclavicular distance between injury side and normal side were analysed in radiologically at before, after and 3 months after operation. Results are as follows; 11.2 mm, -0.5 mm, 0.5 mm, 0.8 mm in group with Mersilene tape, 10.3 mm, -0.5 mm, 1.4 mm, 1.7 mm in Dall-Miles cable. CONCLUSION: Two different fixation material used in the fixation of modified Weaver-Dunn operation have enough fixation power for clinical outcome. But Mersilene tape was better than Dall-Miles cable in the persistency of fixation and handling.
