Pectoralis major tendon transfer in reverse total shoulder arthroplasty with irreparable subscapularis: surgical technique and preliminary clinical and radiological results

“… 30 However, these improvements are not guaranteed, as most studies above cited studies pertain to scenarios with a repairable subscapularis. 12 This issue becomes more challenging in cases of irreparable subscapularis tendons, a frequent situation in RTSA. The importance of subscapularis repair is also a subject of debate.…”

“…The importance of subscapularis repair is also a subject of debate. 12 For instance, Friedman et al observed improved postoperative IR to L1-L3 spinal levels with subscapularis repair compared to L4-L5 levels without repair. 7 Eichinger et al reported significant IR improvement post-RSA with subscapularis repair.…”

The subcoracoid distance is correlated with pain and internal rotation after reverse shoulder arthroplasty

“… 1 Lower humeral NSAs, lateralization of the glenoid, decreasing humeral retroversion, and increasing glenosphere diameter are associated with increased IR. 13 Even with these clinical associations, radiographic correlates have been limited. Kim et al found increased peg-glenoid rim distance was associated with increased IR for patients with rotator cuff arthropathy.…”
