Variable definitions of pseudoparalysis have been used in the literature. Recent systematic
reviews and biomechanical studies call for a grading of loss of force couple balance and the …

Emerging technologies in shoulder arthroplasty, such as 3-dimensional planning software
and real-time intraoperative navigation, are now available for surgeons to perform more …

As massive rotator cuff tears progress, various radiographic changes occur; however, the
factors associated with radiographic changes remain largely unknown. This study aimed to …

Rotator cuff tears are a frequent cause of shoulder pain that often require arthroscopic
repair. After surgery an intense and well-studied rehabilitation protocol is needed to obtain …

Background The primary purpose of this study was to identify demographic, anatomic, and
radiographic risk factors for active forward elevation (AFE)< 90° in the setting of massive …

Background Although glenohumeral instability is common, the mechanism of instability
remains unclear. The purpose of this study was to quantitatively evaluate humeral head …

Purpose The aim of the present study was to compare the diagnostic values of clinical tests
and magnetic resonance imaging (MRI) which used for the diagnosis of subscapularis (SSc) …

Full‐thickness rotator cuff tears can lead to poor coaptation of the humeral head to the
glenoid, disrupting muscle forces required for glenohumeral joint stability, ultimately leading …

Purpose Since poor repeatability of the load and shift test using a grading scale has been
reported, an objective and quantitative method to assess anterior translation should be …

Healthy shoulder function requires the coordination of the rotator cuff muscles to maintain
the humeral head's position in the glenoid. While glenohumeral stability has been studied in …
