Background. Traumatic shoulder instability is a common sequel following first shoulder dislocation, especially in young population (< 30 y.a). Shoulder arthroscopy is getting more and more popular among orthopaedic community. Efficacy of arthroscopic treatment of shoulder instability approaches that of conventional operative techniques. <br /> Aim. The purpose of the study was the analysis of arthroscopic treatment of traumatic shoulder instability. <br /> Material and methods. Study was based on 22 patients, 24 shoulders were operated. Capsulolabral complex has been stabilized arthroscopically in all patients. <br /> Functional was assessed by means of ASES, UCLA and SST scores. Function was improved significantly. There has been no recurrence of instability in follow-up period. <br /> Conclusions. We have proved good efficacy of arthroscopic techniques in treatment of the instability. <br /> Joint stability was restored with decreased invasiveness of operation (better cosmesis, easier rehabilitation).
