A lateral approach to the shoulder joint via a longitudinal myotomy of the supraspinatus muscle was used in the surgical treatment of four cases involving avulsion fractures of the supraglenoid tubercle of the scapula. This approach was developed using cadaver specimens and was compared to previously reported approaches to the supraglenoid tubercle. This approach gave excellent, visualized exposure and permitted accurate reduction and fixation for this type of fracture. Excellent results were achieved in four clinical cases.

Mechanical properties of the bicipital aponeurosis.

As a biarticular muscle, the biceps brachii both supinates the forearm and flexes the elbow and shoulder, thus allowing the upper limb to perform a variety of activities of daily living (ADL). The biceps brachii originates on the coracoid apex as well as the supraglenoid tubercle and inserts on the radial tuberosity. At the distal end, the bicipital aponeurosis (BA) provides a transition of the biceps tendon into the antebrachial fascia.

This study aimed to assess the fusion of growth plates and the development of secondary ossification centres in the forelimb bones of maned wolves (Chrysocyon brachyurus), contrasting the findings with established data from domestic dogs. Three maned wolves, comprising one male and two females, initially aged between 3 and 4 months, were subjected to monthly radiographic evaluations until 10-11 months of age, followed by bimonthly assessments until 18-19 months of age, encompassing both forelimbs. The closure times of growth plates were observed as follows: supraglenoid tubercle (7-8 months), proximal humerus (17-19 months), distal humerus (8-9 months), medial epicondyle of the humerus (8-9 months), proximal ulna (9-10 months), proximal radius (13-15 months), distal ulna (13-15 months) and distal radius (17-19 months).

Subscapularis repair failure following anatomic total shoulder arthroplasty (TSA) can compromise postoperative range of motion and joint stability, often leading to persistent pain and worse outcomes. Augmenting the subscapularis repair, particularly in at-risk patients, may provide a more robust construct and prevent subscapularis failure. The long head of the biceps tendon (LHBT) is an accessible autograft with applications previously described in several shoulder procedures.
