S42.263

Clinical Causes: Trauma from falls onto the shoulder or outstretched arm Direct blow or impact to the shoulder area High-energy accidents such as car crashes or sports injuries Overuse or repetitive stress leading to weakening of the bone (less common)

Key Symptoms: Sudden onset of shoulder pain, especially near the upper arm Swelling and possible bruising around the shoulder joint Limited range of motion or difficulty moving the shoulder Weakness in shoulder movements, especially rotational movements Visible deformity or tenderness when pressing on the shoulder Loss of shoulder function or difficulty lifting or rotating the arm

Diagnosis Path: Diagnosing a displaced fracture of the lesser tuberosity involves a combination of clinical assessment and imaging studies. A healthcare provider will examine the shoulder, check for tenderness, swelling, and range of motion. Confirmatory tests include: - X-rays: Standard imaging to visualize the fracture and assess displacement - MRI or CT scans: May be used in complex cases or to evaluate associated soft tissue injuries such as rotator cuff tears The severity and displacement of the fracture influence treatment decisions and prognosis.

Treatment Protocols: Management of a displaced fracture of the lesser tuberosity typically involves the following approaches: - Rest and immobilization: Using a sling or shoulder immobilizer to allow healing - Pain control: Medications such as NSAIDs may be recommended - Physical therapy: Once initial healing occurs, therapy aims to restore range of motion, strength, and shoulder function - Surgical intervention: In cases of significant displacement or if conservative treatment fails, surgery may be necessary to realign and secure the fractured bone, often with screws or pins. Postoperative care includes immobilization followed by guided rehabilitation. The recovery period varies depending on the severity of the fracture and the treatment method but generally requires several weeks to months for full recovery.
