Introduction. The purpose of this paper is to present and analyze the results of treatment of anterior soft-tissue shoulder instability using an open surgical technique with a minimally invasive anterior approach, as well as to emphasize the benefits of using an open surgical procedure in high-risk patients. Material and Methods. All patients underwent surgery at the Clinic of Orthopedic Surgery and Traumatology in Novi Sad in the period between January 2013 and September 2017. Out of 138 patients undergoing surgery for anterior shoulder instability, 40 patients came for follow-up examination. The average age of subjects was 27 ? 6. Medical history was taken from each patient and the range of motion and muscle strength of the operated shoulder was examined. The subjects filled out a questionnaire regarding the functional status of the operated shoulder, their experience in resuming sports activities, and their subjective feeling of pain. The Constant-Murley score was used to assess the postoperative results. Results. Postoperatively, the mean Constant-Murley score was 90.3 ? 11.5, while 87.5% patients had excellent and good results. Compared to the contralateral uninjured shoulder, there was a statistically significant difference (p < 0.05) in the Constant-Murley score, in external rotation of the abducted shoulder (13.2? ? 10.4?), as well as in shoulder adduction (10.25? ? 9.7?). Out of 35 patients who were athletes, 27 continued to actively engage in sports following the surgical treatment. Four patients had a re-dislocation (10%). Conclusion. Open surgical treatment of the anterior shoulder joint instability using a minimally invasive anterior approach is a reliable, time-tested procedure that provides favorable clinical results in young high-risk contact and overhead athletes with timely diagnosis and surgical care.

Introduction. Acromioclavicular joint has an important role in the shoulder function. Loss of joint function due to injury or disease affects the biomechanics of the shoulder. The aim of this study was to evaluate the results of surgical treatment of acromioclavicular joint injuries, identify risk groups within the age groups, and to indicate the most common mechanisms of injury. Material and Methods. A retrospective study included 20 patients with acromioclavicular injury. We analyzed the results of surgical treatment in patients with acromioclavicular injury from January 2017 to January 2019. Patients were treated using Bosworth and Phemister surgical techniques. The Constant shoulder score was used to assess the results of surgeries. We compared the results of the operated and non-operated shoulders in each patient. Statistical analysis was performed using Student?s T-test and ?? test. Results. Functional assessment was done using the Constant shoulder score: 9 patients had excellent results, 7 had good results and 3 had satisfactory results; there were no patients with poor outcome. We compared the total Constant shoulder score of the operated shoulder with the results of the opposite healthy shoulder, as well as the range of motion of external rotation, and internal rotation range of motion of the operated and the opposite healthy shoulder. There was a statistically significant difference (p < 0.05) in all compared parameters. The total Constant shoulder score of the operated shoulder was by 14% lower in relation to the healthy shoulder. Conclusion. The basic precondition for positive treatment results is timely diagnosis and early surgical intervention. Shoulder function was surgically restored and 95% of patients can perform all activities of daily living.
