    The Shoulder — The Most Mobile Joint, The Most Vulnerable

    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.

    Common Causes

    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.

    How Is Shoulder Pain Evaluated?

    Clinical examination, X-ray, ultrasound (for a quick evaluation of tendons), and MRI (when a rotator cuff or labral tear is suspected).

    When to See an Orthopedist?

    • Persistent pain for over 2-3 weeks
    • You cannot lift your arm above your head
    • Night pain
    • Progressive stiffness
    • Sudden pain with inability to move
    • Weakness when lifting the arm
