ABSTRACT
BACKGROUND: Rockwood Type III acromioclavicular joint injuries are treated both conservatively and surgically. There is still no consensus on an optimal fixation method. The aim of this study was to evaluate which of the surgical methods used in our Department produces the best outcomes in long-term follow-up. MATERIAL AND METHODS: The study involved 27 patients. Wire cerclage was used in 12 patients, 11 patients were operated on by the Ladermann method, and a hook plate was used in 4 patients. The patients were assessed at a late follow-up visit after a mean of 22 months post-operatively. The Constant Shoulder Scale (CSS), Oxford Shoulder Scale (OSS), and PROMIS v1.2 for the upper limb were used to assess the long-term effects of the treatment. RESULTS: There were no statistically significant differences between the Ladermann method and wire cerclage for the scales applied (p=0.98 at α=0.05). The functional CSS showed a significant advantage of the outcomes of the Lader-mann method and wire cerclage in comparison to the hook plate (p=0.014 and p=0.004, respectively, at α=0.05). The quality of life scales OSS and PROMIS showed no significant difference between the methods. CONCLUSIONS: 1. The outcomes of treatment with the Ladermann method and wire cerclage are excellent and com-parable with regard to both clinical outcomes and the quality of life. 2. The use of a hook plate may substantially contribute to worse clinical outcomes. 3. No considerable difference was found in the quality of life between the different groups, but a study involving a larger number of patients would be necessary for a complete evaluation.
