Acromio clavicular acute dislocation. Results with double endobutton technique without ligament reconstruction

Abstract

Background: The acromioclavicular (AC) joint injuries are common, accounting for 9% of all injuries to the shoulder girdle. The multitude of techniques describes and illustrates the fact that the ideal technique to treat a symptomatic AC joint dislocation remains to be found.
Materials & methods: From January 2011 to December 2013, 15 patients with acute acromioclavicular joint dislocation were surgically immobilized with the double Endobutton® technique without ligament reconstruction. All the patients had type V AC dislocations according to Allman-Rockwood classification. Among the patients, 12 patients were male and 3 patients were female, with an average age of 35 years (ranged from 22 to 56 years). The therapeutic effects were evaluated with postoperative X-ray, at 1, 3 and 12 months.
Results: From fifteen patients in this study, seven patient lost radiographic reduction during the first year of postoperative procedure compared with the first post-operative Rx. There were no other complications reported.
Discussion: We obtained with the double Endobutton® AC reduction without ligament reconstruction a 46% of loosening reduction in the first year. This technique has a high percentage of loss of reduction in this type of patient.
Evidence level: IV.
