S42.212

Clinical Causes: Falls onto an outstretched arm or shoulder Direct blow to the upper arm or shoulder Trauma from vehicular accidents Sports-related injuries, such as falls or collisions Osteoporosis making bones more susceptible to fracture

Key Symptoms: Sudden onset of severe pain in the upper arm or shoulder Swelling and tenderness around the shoulder area Deformity or abnormal positioning of the arm Inability to move or lift the arm Bruising or discoloration over the site of the injury Possible numbness or tingling if nerves are affected

Diagnosis Path: Diagnosing a displaced fracture of the surgical neck of the humerus involves a combination of clinical evaluation and imaging studies. A healthcare provider will perform a physical examination, assessing pain, swelling, and arm movement. Imaging tests such as X-rays are essential to confirm the fracture, determine displacement, and assess the extent of injury. In some cases, additional imaging like MRI or CT scans may be used for detailed assessment, especially if the fracture pattern is complex.

Treatment Protocols: Treatment options depend on the severity and displacement of the fracture. Common management strategies include: - **Immobilization:** Using a shoulder immobilizer or sling to keep the arm still, allowing the bone to heal naturally. - **Reduction:** If the bones are displaced, a healthcare professional may need to realign the fractured segments through a procedure called reduction. - **Surgical intervention:** In cases of significant displacement or involving complex fracture patterns, surgery may be necessary to realign and stabilize the bone using devices like plates, screws, or pins. - **Rehabilitation:** Physical therapy is often recommended after initial healing to regain strength, motion, and functionality of the shoulder and arm. Healing times vary but typically span several weeks to months, depending on age, overall health, and the severity of the fracture.
