Relationship between postoperative integrity of subscapularis tendon and functional outcome in reverse shoulder arthroplasty.

Hypothesis And Background: The role of the subscapularis in reverse shoulder arthroplasty (RSA) remains controversial. Studies have shown that subscapularis repair has no significant influence on the functional outcomes of patients. However, few studies have assessed the postoperative integrity of the subscapularis tendon after RSA.

Factors associated with internal rotation outcomes after reverse shoulder arthroplasty.

Background: Reverse shoulder arthroplasty (RSA) was introduced in 1985 by Grammont for patients with gleno-humeral osteoarthritis and severe rotator cuff damage. Internal rotation (IR) is limited in some patients after RSA. The objective of this study was to identify pre- and intra-operative factors associated with good IR outcomes 6 months after RSA.

Diagnosis of long head of biceps tendinopathy in rotator cuff tear patients: correlation of imaging and arthroscopy data.

Introduction: The goal of this prospective study was to assess the reliability of pre-operative cross-sectional imaging for the diagnosis of long head of biceps (LHB) tendinopathy in patients with a rotator cuff tear.

Methods: Cross-sectional imaging with MRI or CT arthrography data from 25 patients operated upon because of a rotator cuff tear between 1 October 2015 and 1 April 2016 was analysed by one experienced orthopaedic surgeon, one experienced radiologist and one orthopaedic resident. The analysis consisted of determining whether the LHB was present, the extrinsic tendon abnormalities (dislocation, tendon coverage) and intrinsic abnormalities (fraying, inflammation, degeneration).
