Glenoid labrum is fibrocartilaginous structure around shoulder blade rim. Labrum deepens shallow shoulder socket, stabilizing ball-and-socket joint. Triangular structure with fixed base and thin, sharp free edge. Continuous with biceps tendon's long head fascicles
Retrospective study of 100 patients with shoulder pain using MRI. Acromion types classified as type-I (flat), type-II (curved), type-III (hooked). Measurements included acromion length, slope, and various angles
Scapular push-ups improve shoulder stability and proper upper body alignment. Poor scapula mechanics can lead to shoulder injuries and poor posture. Exercise is commonly used in shoulder warm-up and recovery phases
Rotator interval is triangular space between subscapularis, supraspinatus, and coracoid. Contains coracohumeral, superior glenohumeral ligaments, biceps tendon, and anterior capsule. Functions as check-rein against excessive shoulder motion. Contributes to stability of glenohumeral joint and biceps tendon
Clavicle is an S-shaped bone located between shoulder and sternum. Divided into sternal, shaft, and acromial ends. Forms two joints: acromioclavicular and sternoclavicular. Attached to five muscles, primarily subclavius
Rotator cuff is a functional unit in upper extremity. Four muscles: subscapularis, teres minor, supraspinatus, infraspinatus. All muscles originate from scapula and insert into humerus
