M75.40

Clinical Causes: Repetitive overhead activities, such as sports or occupational tasks Degeneration of shoulder tendons with age Shoulder injuries or trauma Structural abnormalities such as bone spurs or a hooked acromion Poor posture leading to altered shoulder mechanics Weakness or imbalance in shoulder muscles

Key Symptoms: Pain when lifting the arm or reaching overhead Deep shoulder pain that worsens with activity Tenderness around the shoulder Limited range of motion in the shoulder joint Weakness in shoulder movements Difficulty performing daily activities involving shoulder movements Possible clicking or grinding sensations

Diagnosis Path: Diagnosing impingement syndrome involves a combination of a detailed medical history, physical examinations, and imaging tests. The healthcare provider may perform specific shoulder tests to identify signs of impingement, such as the Neer or Hawkins-Kennedy tests. Imaging modalities like X-rays can reveal structural abnormalities like bone spurs, while MRI scans provide detailed images of soft tissues, including tendons and bursae, to detect inflammation or tears.

Treatment Protocols: Treatment options aim to reduce shoulder pain, improve function, and prevent further damage. Common approaches include: - Rest and activity modification to avoid aggravating movements - Physical therapy focused on stretching and strengthening shoulder muscles - Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief - Corticosteroid injections in cases of severe inflammation - Ultrasound therapy or other modalities to promote healing - Surgical intervention, such as subacromial decompression, if conservative measures fail or if there are structural abnormalities requiring correction Recovery often involves a structured rehabilitation program designed to restore shoulder strength and mobility, helping patients return to daily activities comfortably.
