The shoulder allows for a wide range of motion, but its stability is provided by muscles and tendons, not solid bone structures. This makes it prone to various conditions.
Rotator cuff tendinopathy / tear — the most frequent cause in adults. → Read about rotator cuff tears
Adhesive capsulitis (frozen shoulder) — progressive stiffness. → Read about adhesive capsulitis
Subacromial impingement syndrome — pain when lifting the arm to the side.
Glenohumeral osteoarthritis — advanced stages may require arthroplasty. → Shoulder replacement
Shoulder instability — the sensation of the shoulder "popping out of place."
Calcifications (calcific tendinitis) — calcium deposits, causing episodic acute pain.
Clinical examination, X-ray, ultrasound (for a quick evaluation of tendons), and MRI (when a rotator cuff or labral tear is suspected).
