Item Reverse total shoulder arthroplasty for failed treatment of proximal humerus fractures(TURKISH ASSOC ORTHOPAEDICS TRAUMATOLOGY, 2021-01-01) Karademir, Gokhan; Tunali, Onur; Ersen, Ali; Akpinar, Sercan; Atalar, Ata CanObjective: The aim of this study was to evaluate the functional and radiological outcomes and complications of reverse total shoulder arthroplasty (RTSA) for failed treatment of proximal humerus fractures (FTPHF). Methods: In this retrospective study, 20 patients (17 female, 3 maleItem A Clinical Comparison of Home-Based and Hospital-Based Exercise Programs Following Arthroscopic Capsulolabral Repair for Anterior Shoulder Instability(HUMAN KINETICS PUBL INC, 2020-01-01) Eren, Ilker; Canbulat, Nazan; Atalar, Ata Can; Eren, Sule Meral; Ucak, Ayla; Cerezci, Onder; Demirhan, MehmetContext: Ideal rehabilitation method following arthroscopic capsulolabral repair surgery for anterior shoulder instability has not been proven yet. Although rapid or slow protocols were compared previously, home- or hospital-based protocols were not questioned before. Objective: The aim of this prospective unrandomized controlled clinical trial is to compare the clinical outcomes of home-based and hospital-based rehabilitation programs following arthroscopic Bankart repair. Design: Non-randomized controlled trial. Setting: Orthopedics and physical therapy units of a single institution. Patients: Fifty-four patients (49 males and 5 females) with an average age of 30.5 (9.1) years, who underwent arthroscopic capsulolabral repair and met the inclusion criteria, with at least 1-year follow-up were allocated into 2 groups: home-based (n = 33) and hospital-based (n = 21) groups. Interventions: Both groups received identical rehabilitation programs. Patients in the home-based group were called for follow-up every 3 weeks. Patients in the hospital-based group admitted for therapy every other day for a total of 6 to 8 weeks. Both groups were followed identically after the eighth week and the rehabilitation program continued for 6 months. Main Outcome Measures: Clinical outcomes were assessed using Disabilities of Arm Shoulder Hand, Constant, and Rowe scores. Mann-Whitney U test was used to compare the results in both groups. Wilcoxon test was used for determining the progress in each group. Results: Groups were age and gender matched (P= .61, P = .69). Average number of treatment sessions was 13.8 (7.3) for patients in the hospital-based group. Preoperative Disabilities of Ann Shoulder Hand (27.46 {[}11.81] vs 32.53 {[}16.42], P= .22), Constant (58.23 {[}14.23] vs 54.17 {[}10.46], P = .13), and Rowe (51.72 {[}15.36] vs 43.81 {[}19.16], P= .12) scores were similar between groups. Postoperative scores at sixth month were significantly improved in each group (P = .001, P = .001, and P = .001). No significant difference was observed between 2 groups regarding clinical scores in any time point. Conclusions: We have, therefore, concluded that a controlled home-based exercise program is as effective as hospital-based rehabilitation following arthroscopic capsulolabral repair for anterior shoulder instability.Item Do we need to stabilize and treat the os acromiale when performing reverse shoulder arthroplasty?(ELSEVIER MASSON, CORPORATION OFFICE, 2019-01-01) Ersen, Ali; Bayram, Serkan; Atalar, Ata Can; Demirhan, MehmetIntroduction: The purpose of this study is to investigate the incidence of os acromiale in patients who had reverse shoulder arthroplasty (RSA) for rotator cuff tear arthropathy and the effect of presence of os acromiale on the functional results. Hypothesis: We hypothesize than in the presence of os acromiale, the contraction strength of the deltoid would decrease due to the dynamic downward depression of the bony fragment leading to less favorable clinical results. Material and method: A total 46 patients with a mean age of 70.8 who had RSA and a minimum follow-up of 24 months were included in this study. Preoperative radiographs, computerized tomography scans and magnetic resonance images were examined to determine the presence of os acromiale. Results: A total of 10 patients out of 46 (22\%) with os acromiale, all of which were of mesoacromion type, were followed up for 59.7 months. While both groups had significant improvements in Constant, Q-DASH and VAS scores compared to their preoperative status, a significant difference between the groups could not be found. The radiological evaluation showed that the average acromiohumeral distance significantly increased postoperatively in both groups. The acromiohumeral distance was significantly shorter in patients with os acromiale. Discussion: While the presence of os acromiale does not have an adverse effect on the clinical results of the RSA, the loose fragment can migrate distally in the postoperative period due to the tension in the deltoid.

Open pectoralis major (PM) tendon Z-plasty and arthroscopic subscapularis (SS) release are 2 options for the release of internal rotation contractures to enhance muscle transfers. This study compared the functional results of LD and TM tendon transfers with open PM tendon Z-plasty or arthroscopic SS release. Methods: The study included 24 patients who underwent LD and TM tendon transfers for OBPP (9 arthroscopic SS release, 15 open PM tendon Z-plasty) with a mean follow-up of 41.33 months (range, 3660 months) and 47.2 months (range, 36-60 months), respectively. Functional evaluation was made according to range of motion and Mallet scoring system. Results: Shoulder abduction-external rotation degrees and scores in all sections of the Mallet scoring system significantly increased in both groups (P < .001). Postoperatively, the arthroscopic SS release group had significantly better abduction degrees (P = .003), total Mallet scores (P < .001), and superior abduction (P = .043), active external rotation (P = .043), hand-to-head (P = .043), and hand-to-mouth (P < .001) scores for the Mallet scoring system. Discussion: Transfer of LD together with TM tendons combined with one of the internal rotation contracture release procedures yielded good clinical and functional results in patients younger than age 7, regardless of the type of release method. However, arthroscopic SS release, although requiring an experienced surgeon, revealed better clinical and functional outcomes and is considered to be a less invasive and superior method.
