Comparison of single versus double TightRope system in the treatment of acute acromioclavicular joint dislocation

BackgroundReconstruction of the coracoclavicular (CC) ligament using a single TightRope (ST) system has some complications. We attempted to use double (DT) reduce complications and obtain ideal therapeutic effect.PurposeThis investigation aimed compare ST DT systems in terms efficacy safety treating acromioclavicular (AC) joint dislocation.MethodsSixty-six cases acute AC dislocation between January 2013 2018 were retrospectively reviewed. All patients divided into 2 groups based on treatment with or system. Patients evaluated radiologically clinically Disability Arm, Shoulder, Hand, Constant, visual analog scale scores as clinical outcome measures at 1 day, 3 weeks, 6 months, year, years after surgery. The CC distance displacement ratio assessed radiologically.ResultsThe mean follow-up period was 49 months. Satisfactory outcomes obtained fixation both groups. No intergroup difference found regarding (P = .80), Hand .42), Constant score .28) years. However, there significant weeks < .0001), months year .0001) postoperatively There group, including case secondary coracoid fracture, arthrosis combined ossification ligaments, clavicular erosion. occurred group.ConclusionsBoth surgical methods are effective dislocation, but is more reliable for reduction maintenance.
