Overview¶

• Patients with irreparable massive rotator cuff tears without osteoarthritis have a high likelihood of achieving a painless shoulder and functional improvements after reverse shoulder arthroplasty [1].
• Reverse shoulder arthroplasty provides optimal outcomes with low complication rates across a short term of follow-up for glenohumeral osteoarthritis with an intact rotator cuff [2].
• Subacromial balloon spacers for massive rotator cuff tears demonstrate clinically relevant improvements in shoulder range of motion and substantial improvements in patient-reported outcome measures in the short term [3].
• Arthroscopic repairs of chronic, massive rotator cuff tears, whether complete or partial, are associated with significant improvements in pain, function, and objective outcome scores with a low rate of re-tear [5].
• Differences in postoperative patient-reported outcomes and improvement from baseline show a trend toward lower outcomes in patients with prior rotator cuff repair undergoing reverse shoulder arthroplasty, but these differences may be below the minimal clinically important difference [7].
• Superior capsular reconstruction serves as a reasonable joint-preserving option for massive, irreparable rotator cuff tears, with favorable short- to midterm improvements in patient-reported outcomes and range of motion irrespective of tissue source [8].
• For patients younger than 70 years with massive irreparable rotator cuff tears without significant arthritis or pseudoparalysis, graft interposition repair techniques, superior capsular reconstruction using the long head of the biceps tendon, arthroscopic debridement, and balloon arthroplasty provide superiority in various outcome domains [10].
• Nonarthroplasty treatment options for irreparable rotator cuff tears result in statistically significant improvements in range of motion and patient-reported outcomes at 1 year follow-up or more, with low rates of revision and conversion to arthroplasty [14].
• Anatomic total shoulder arthroplasty displays equal functional results and postoperative complications compared to reverse total shoulder arthroplasty in patients over 70 without a full-thickness rotator cuff tear [17].
• Higher revision rates were identified following anatomic total shoulder arthroplasty compared to reverse total shoulder arthroplasty in patients over 70 without a full-thickness rotator cuff tear, although this finding is within retrospective studies [17].
• Complications for primary reverse shoulder arthroplasty using augmented baseplates are within an acceptable range, with a low rate of revision [18].
• Patients undergoing reverse total shoulder arthroplasty for glenohumeral osteoarthritis, cuff tear arthropathy, or massive rotator cuff tear are generally satisfied with their procedure [24].
• The rate of satisfaction is highest in patients undergoing reverse total shoulder arthroplasty for glenohumeral osteoarthritis [24].

Anatomy & Pathophysiology¶

• Reverse total shoulder arthroplasty (RTSA) is indicated for patients with irreparable massive rotator cuff tears who do not have osteoarthritis [1].
• RTSA is indicated for patients with rotator cuff arthropathy (RCA) [40].
• RTSA yields slightly lower shoulder function, range of motion, and a higher dislocation-related revision risk compared to its use for proximal humerus fractures (PHF) [40].
• RTSA results in an increased contribution of scapulothoracic rotation relative to glenohumeral motion throughout arm elevation compared to asymptomatic shoulders [30].
• RTSA is associated with no significant deterioration in shoulder function and outcome scores between 5 and 20 years of follow-up [15].
• Shoulder scores may decline at mid- to long-term follow-up for patients with large and massive irreparable rotator cuff tears treated with soft tissue reconstruction techniques [4].
• Soft tissue reconstruction for irreparable anterosuperior rotator cuff tears is associated with improved clinical outcomes [19].
• For patients younger than 70 years with massive irreparable rotator cuff tears without significant arthritis or pseudoparalysis, graft interposition repair, superior capsular reconstruction using the long head of the biceps tendon, arthroscopic debridement, and balloon arthroplasty provide superiority in various outcome domains [10].
• Subacromial balloon spacers resist superior humeral head migration and reduce subacromial pressure in cadaveric studies [36].
• Subacromial balloon spacer implantation results in improved shoulder function and decreased pain at 24 months post-procedure [44].
• The majority of painful complications after RTSA, including instability, fractures, and infection, can be successfully treated to maintain a functional implant [20].
• There are no differences in abduction, internal rotation, or external rotation strength after RTSA with or without subscapularis repair [37].
• There appears to be a trend suggesting improved postoperative clinical outcomes and active range of motion for patients with a subscapularis repair versus without a repair after primary RTSA [45].
• Studies analyzing the impact of subscapularis repair on internal rotation following RTSA report conflicting results [41].
• Measures and reporting of shoulder internal rotation after RTSA vary widely, making it difficult to assess associations between postoperative internal rotation limitation and functional abilities [38].
• The anterosuperior approach for RTSA offers better forward flexion, while the deltopectoral approach is associated with a lower glenoid loosening rate [35].
• Changes in humeral stem inclination in RTSA are accompanied by less scapular notching and dislocations, with no clear impact on functional outcome measures [32].

Proximal Humerus Fractures (Elderly Population)¶

• Reverse shoulder arthroplasty is a better option than hemiarthroplasty for proximal humerus fractures in the elderly [39].
• Clinical decision for reverse shoulder arthroplasty in proximal humerus fractures should be preferred on the condition that the patient's medical conditions are indicated [39].
• Consideration may be given to an initial trial of nonoperative treatment for acute proximal humeral fractures in the elderly, saving reverse total shoulder arthroplasty for those in whom nonoperative treatment fails without compromising the ultimate outcome [47].

Complications¶

Complications¶

• Complications are within an acceptable range for primary reverse shoulder arthroplasty using augmented baseplates, with a low rate of revision [18].
• Complications do not appear to be appreciably higher in the reverse shoulder arthroplasty group compared to other treatments for proximal humeral fractures in older adults in existing follow-up [51].
