S62.312

Clinical Causes: Falling onto an outstretched hand during an accidental fall Direct blow to the back of the hand during sports or a physical altercation Motor vehicle accidents involving hand impact Crush injuries from heavy objects falling onto the hand Repetitive stress or overuse, though less common for displaced fractures

Key Symptoms: Immediate, severe pain at the injury site Swelling and tenderness around the base of the third metacarpal Deformity or visible misalignment of the hand Bruising in the hand or wrist area Difficulty moving or gripping objects Reduced strength or sensation in the affected finger or hand

Diagnosis Path: To confirm a displaced fracture, healthcare providers typically perform a physical examination and order imaging tests. An X-ray of the hand will reveal the location, extent, and displacement of the fracture. In some cases, additional imaging like a CT scan may be used for detailed visualization, especially if surgical intervention is considered.

Treatment Protocols: Management depends on the severity and displacement of the fracture. Common approaches include: - **Immobilization:** Using a cast or splint to stabilize the bone and allow natural healing. This is often suitable for minimally displaced fractures. - **Reduction:** If the bone fragments are misaligned, a healthcare provider may perform a closed reduction, manually realigning the fracture without surgery. - **Surgical Intervention:** Severe displacement or unstable fractures may require open reduction and internal fixation (ORIF), involving pins, plates, or screws to maintain proper alignment during healing. - **Pain Management:** Over-the-counter or prescribed medications can help control pain and reduce inflammation. - **Rehabilitation:** Once the fracture begins to heal, hand therapy may be recommended to restore strength, flexibility, and function.
