Massive irreparable rotator cuff tears represent a vexing problem, particularly in the physiologically young patient with no glenohumeral arthritis and high functional expectations. Not even the last line of defense, the reverse shoulder arthroplasty, can help all of our patients with massive irreparable rotator cuff tears and resultant pseudoparalysis, and in younger patients, joint preservation could be a preferable first-line intervention. Superior capsular reconstruction (SCR) shares the joint-preservation arena with an evolving multitude of options, including arthroscopic debridement, partial rotator cuff repair, biologic tuberoplasty, interposition balloon spacer, and lower trapezius tendon transfer. SCR shows promising biomechanical and clinical outcomes, including restoration of native glenohumeral biomechanics and contact pressures, achievement of humeral head depression, reduction of pain, and improved patient-reported outcome measures and range of motion, despite a high rate of graft retear or discontinuity. Yet, comparable results may be achieved via simpler procedures, including debridement, partial repair, tuberoplasty, and/or spacer. Ultimately, the true value of SCR, or any other technique, would be proven improvement in strength or survivorship from subsequent surgery, particularly reverse arthroplasty. Optimizing indications for these constantly evolving techniques is a moving target and essential for selecting the greatest value procedures for patients on the basis of their individual needs.

Background: Muscle atrophy after the rupture of a rotator cuff (RC) tendon is a major factor that increases the risk of secondary complications and re-rupture. Metformin, a type 2 diabetes treatment, can be used to modulate intracellular signaling pathways that promote muscle growth. This study aimed to verify whether systemic metformin administration could prevent supraspinatus (SS) atrophy after RC rupture in a rat model.

Purpose: The purpose of this study was to evaluate the integrity of the repaired rotator cuff between 1 and 2 years postoperatively after arthroscopic rotator cuff repair (ARCR) using magnetic resonance imaging (MRI), investigate the factors affecting its change, and assess the association between the change and postoperative clinical outcomes.
Methods: Rotator cuff tear patients who underwent ARCR and were evaluated by MRI before surgery, and 1 and 2 years after ARCR with a minimum of 2-year follow-up were included in this study. Repair integrity was evaluated using Sugaya's classification, and according to the classification types IV and V were defined as re-tears.

Purpose: The aim of this study was to compare the safety and efficacy of immobilizing the upper limb with a brace versus a less-constrained sling in the rehabilitation after arthroscopic rotator cuff repair (ARCR), by documenting clinical and radiological results.
Methods: ARCR was performed in 110 patients (54.9±8.

Shoulder and elbow injuries are prevalent among baseball players, particularly pitchers, who experience repetitive eccentric loading of the shoulder, leading to muscle damage and increased injury risk. Nearly 40% of shoulder injuries in baseball occur in pitchers, with many facing low rates of return to sport. The rotator cuff (RC) muscles-supraspinatus (SSP), infraspinatus (ISP), subscapularis (SSC), and teres minor (TMin)-are crucial for shoulder stability, movement, and force generation, particularly in overhead sports.

Shoulder pain often involves the tendon of the long head of the biceps brachii (LHBT) and the transverse humeral ligament (THL). Traditionally, the THL is considered a ligament that prevents the LHBT from dislocating, but recent studies suggest that it may be part of the subscapularis tendon. This review evaluates the nature of the THL and its overlying structures.
