Arthroscopic Coracoclavicular Reconstruction Combined with Open Acromioclavicular Reconstruction Using Knot Hiding Clavicular Implants Is a Stable Solution

Abstract

Shoulder dislocation is a common injury, usually caused by falling. The prevalence in Western countries is about 18/100 000. The severity of the injury is measured on the Rockwood scale. Conservative treatment is used for Rockwood class I and II and some class III injuries. IV-VI class injuries are usually surgically treated. There is no consensus on the best treatments and surgical techniques. In this study, the recovery of traumatically dislocated scapulas treated arthroscopically was examined. A total of 32 patients with Rockwood class III and V were included in the study. The patients were operated on arthroscopically using CC clip® graft, which were used to bind the scapula, coracoid, and acromion together. The total follow-up time was two years after surgery. The healing of the surgical wounds, complications, the patients' own feelings and satisfaction with shoulder use and surgery and few different scores that measure usability of the shoulder in daily life was monitored. X-ray and CT imaging were used also. Based on the results of our study, it seems that the CC-clip® graft and arthroscopic surgery are suitable for treating Rockwood class III and V shoulder dislocation injuries. The results of the questionnaire and scores show that the usability of the shoulder and pain improved during the follow-up period. The substitute and surgical technique seem to have a positive effect on the recovery of the injured shoulder. There were some complications during the follow-up period, but they were small and did not affect the overall result significantly.
