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.
