Clinical Efficiency after Fixation with Cable in Patellar Fracture

PURPOSE: To evaluate the clinical results of cable fixation in patellar fractures followed by early ROM exercise and early weight bearing. MATERIALS AND METHODS: We analyzed 46 patients who had operation for transverse or comminuted patellar fractures with cable fixation from April 1995 to January 2003. Mean term of follow up was 15 months (range, 15~24 months). We reviewed the clinical and radiologic bony unions, ROM, time of weight bearings retrospectively. All cases were fixed with Dall-Miles' cable, and additional fixation was done with K-wires in 25 cases and with screws in 11 cases. At next day after surgery, all patients started CPM, except 3 cases who had severly comminuted fractures. Full weight bearing was started 2-3 days after surgery with LMB in full extended state. RESULTS: We gained bony union in all cases, Average ROM was 115 degree(80-130 degree) at postoperative 2nd week, all patients showed more than 130 degree at 8th week and final results showed normal ROM compared with opposite knee. During follow up, K-wires were migrated in 2 cases, but there was no difference in ROM or bony union compared with other patients. CONCLUSION: Fixations using Dall-Miles' cable for transverse or comminuted patellar fractures are considered to be enough stable for early ROM exercise and early weight bearing without major complications.

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.
