L-Shape Superior Capsular Augmentation Technique Using Biceps Tendon: The Biceps L-Shape Shifting Technique.

Many therapies have been developed for patients with mass rotator cuff tears. Partial repair is often performed in patients with partially repairable massive rotator cuff tears because it is simpler to perform than superior capsule reconstruction. It may, however, result in rotator cuff retears frequently.

Three-dimensional in vivo comparative analysis of the kinematics of normal shoulders and shoulders with massive rotator cuff tears with successful conservative treatment.

Background: This study used in vivo three-dimensional to two-dimensional image registration techniques to compare the glenohumeral kinematics of shoulders with massive rotator cuff tears that were successfully treated conservatively and those of normal shoulders.

Methods: Ten patients (age, 67.4 ± 3.
