A powerlifting athlete ruptured his left tendon of the pectoralis major muscle while attempting to lift 160 kg in a Brazilian bench press championship. The injury seemed to occur in the concentric phase of exercise; however, the more common mechanism of rupture is during the eccentric phase. The tendon was reinserted to the humerus 3 weeks later with screws and washers. The athlete returned to competitive activities after 5 months. One year later he lifted 170 kg and won the national championship.

Objective: The purpose of this report is to describe the presentation of a patient with a pectoralis major tendon (PMJ) tear.
Clinical Features: A 30-year-old male weightlifter presented to a chiropractor with localized left arm pain that began while bench-pressing. Ecchymosis and swelling were present, but no contour abnormalities were seen.

Tenodesis of the long head of biceps is a common shoulder surgical procedure. Tenodesis can be performed either arthroscopically or open and within the glenohumeral joint, within the bicipital groove, or below the pectoralis major tendon insertion. Arthroscopic tenodesis of the biceps tendon reduces the risk of infection.

Background: The incidence of revision shoulder arthroplasty continues to rise, and infection is a common indication for revision surgery. Treatment of periprosthetic joint infection (PJI) in the shoulder remains a controversial topic, with the literature reporting varying methodologies, including the use of debridement and implant retention, single-stage and 2-stage surgeries, antibiotic spacers, and resection arthroplasty. Single-stage revision has been shown to have a low rate of recurrent infection, making it more favorable because it precludes the morbidity of a 2-stage operation.

Rupture of the pectoralis major muscle is extremely rare in adolescents. The current literature contains only 5 reports of this condition in patients under 20 years old, with 2 reports in subjects under 16. In the present article, we report the case of a 15-year-old volleyball player who suffered a traumatic rupture of the pectoralis major in a match during the serve movement.

Background: The restriction of active internal rotation (IR) after reverse shoulder arthroplasty (RSA) poses a challenging problem for reconstructive shoulder surgeons, particularly in patients suffering from massive rotator cuff tears (mRCT) with subscapularis (SSC) deficiency. This study aims to evaluate the biomechanical effectiveness of different tendon transfer techniques following medialized glenoid and lateralized humerus RSA in improving internal rotation (IR) strength.
Methods: Eight cadaveric shoulder specimens were evaluated using a custom shoulder testing system designed to simulate loading conditions typical of mRCT with SSC insufficiency.
