S62.013

Clinical Causes: Falls onto an outstretched hand, especially with the wrist extended or dorsiflexed Direct trauma to the wrist during sports, accidents, or falls Motor vehicle accidents causing direct impact to the wrist Repetitive stress or overuse in activities involving wrist trauma

Key Symptoms: Pain localized over the wrist, especially near the thumb side Swelling and tenderness around the wrist Reduced range of motion or stiffness in the wrist Difficulty gripping or performing movements that involve the wrist Visible deformity or abnormal positioning of the wrist in severe cases Possible bruising around the injury site

Diagnosis Path: Diagnosis typically involves a combination of clinical evaluation and imaging techniques. A healthcare provider will examine the wrist for tenderness, swelling, and deformity. To confirm the fracture and determine displacement, imaging studies such as X-rays are essential. In some cases, additional imaging like CT scans or MRI may be used to assess the severity of the fracture and involvement of surrounding tissues, especially in complex or non-healing cases.

Treatment Protocols: Treatment of a displaced fracture of the distal pole of the navicular (scaphoid) bone usually depends on the degree of displacement and stability of the fracture. Common approaches include: - **Immobilization:** Using a cast or splint to keep the wrist and hand steady, typically for several weeks. - **Surgical intervention:** May involve internal fixation with screws or pins to realign the bone fragments, especially in cases with significant displacement. - **Post-treatment care:** Includes immobilization post-surgery, pain management, physical therapy to restore motion and strength, and regular follow-up imaging to ensure proper healing. Because the blood supply to the scaphoid can be limited, especially in the distal pole, prompt and appropriate treatment is critical to prevent complications such as nonunion or avascular necrosis.
