S62.252

Clinical Causes: Direct trauma to the thumb area, such as a fall or blow Sports injuries involving falls or collisions Accidental impacts during activities like lifting heavy objects improperly Falls onto an outstretched hand, transmitting force to the thumb Crush injuries or crushing accidents involving the hand

Key Symptoms: Immediate pain in the thumb or base of the hand Swelling around the thumb or palm Tenderness when touching the affected area Deformity or abnormal bump near the thumb joint Inability to move or grip with the affected hand Bruising around the injury site Difficulty in performing tasks that require thumb movement

Diagnosis Path: Diagnosis typically involves a comprehensive clinical assessment and imaging studies. A healthcare provider will examine the affected hand for deformity, swelling, and movement limitations. Diagnostic imaging, such as X-rays, confirms the fracture's presence, its displacement degree, and the exact location, enabling appropriate treatment planning.

Treatment Protocols: Treating a displaced fracture of the first metacarpal neck requires restoring proper bone alignment for optimal healing. Treatment options include: - **Immobilization:** The use of a cast or splint to hold the bone in place, allowing natural healing. - **Reduction procedures:** If the fracture is significantly displaced, a healthcare provider may perform either closed reduction (manipulating the bone externally) or open reduction (surgical realignment). - **Surgical intervention:** Surgery may involve internal fixation with pins, screws, or plates to stabilize the bone. - **Rehabilitation:** Following immobilization or surgery, hand therapy and exercises help restore strength, flexibility, and function. Recovery times vary depending on the severity of the fracture and the treatment method, generally requiring several weeks of healing and rehabilitation.
