Reverse Total Shoulder

Anatomical total shoulder arthroplasty (TSA) has been used widely in treatment of glenohumeral osteoarthritis and provides excellent pain relief and functional results. Reverse total shoulder arthroplasty (RSA) was created to treat the complex problem of rotator cuff tear arthropathy. RSA also has been performed for glenohumeral osteoarthritis even in cases where the rotator cuff is preserved and has shown good results comparable with TSA. The indications for RSA are expanding to include tumors of the proximal humerus, revision of hemiarthroplasty to RSA, and revision of failed TSA to RSA. The purposes of this article were to describe comprehensively the conditions under which RSA should be considered in glenohumeral osteoarthritis, to explain its theoretical background, and to review the literature.

Reverse Total Shoulder

Background Deltoid muscle function is paramount to the success of reverse total shoulder arthroplasty. The purpose of this study was to investigate the role of deltoid volume on shoulder range of motion and patient-reported outcomes following reverse total shoulder arthroplasty in rotator cuff-intact and rotator cuff-deficient conditions. Methods Retrospective review of records identified 107 patients who met inclusion criteria. The rotator cuff integrity was evaluated by two musculoskeletal-trained radiologists. Volumetric deltoid measurements were calculated from preoperative computed tomography or magnetic resonance imaging scans. Satisfactory outcomes were defined as forward elevation of at least 135°, external rotation of at least 35°, and American Shoulder and Elbow Surgeons and Single Assessment Numerical Evaluation scores of at least 70. Results Mean total deltoid muscle volume was significantly higher in patients with satisfactory forward elevation (57.8 ± 18.1 cm³) versus unsatisfactory forward elevation (48.6 ± 19.5 cm³) (p = 0.013). When separated by rotator cuff integrity, total deltoid volume was significantly higher (p = 0.030) in patients who achieved satisfactory forward elevation in the rotator cuff-deficient group but not the rotator cuff-intact group (p = 0.533). Discussion Preoperative deltoid volume directly correlated with achieving satisfactory forward elevation after reverse total shoulder arthroplasty in rotator cuff-deficient conditions and may be one factor in determining the ability to achieve satisfactory outcomes in the rotator cuff-deficient patient.

Rotator Cuff Arthropathy

A reverse total shoulder arthroplasty (RTSA) is strongly suggested for patients who suffer from rotator cuff (RTC) arthropathy, where RTC deficiency causes abnormal loading leading to articular cartilage damage. Studies show that 47% of RTSA patients have rotator cuff arthropathy and 27% have some form of osteoarthritis (OA) [1].

Reverse Total Shoulder

Reverse total shoulder arthroplasty (rTSA) is used to improve pain and function in arthritic, rotator cuff deficient shoulders. Surgical intervention is considered successful if range of motion and stability of the joint is maximized and force to abduct the arm is minimized. Implant hardware positioning may affect these outcome measures.
