Reverse shoulder arthroplasty with and without concomitant latissimus dorsi and teres major transfer for shoulder pseudoparalysis with teres minor dysfunction: a prospective, randomized investigation

Introduction: Reverse shoulder arthroplasty (RSA) can restore active elevation in a cuff-deficient, pseudoparalytic shoulder. However, RSA alone does not restore active external rotation, which is impaired in patients with teres minor dysfunction. Persistent teres minor dysfunction, following RSA, has been associated with diminished functional outcomes and patient satisfaction, stemming from an inability to control spatial positioning of the arm. To address this concern, latissimus dorsi and teres major tendon transfers have been performed concurrently with RSA to restore both active elevation and external rotation.
