S63.106

Clinical Causes: Falls onto an outstretched hand or directly onto the thumb Sports injuries, especially during contact sports or activities involving falls Twisting or hyperextension injuries Accidental trauma during everyday activities Motor vehicle accidents

Key Symptoms: Sudden pain in the thumb at the time of injury Swelling and tenderness around the thumb joint Deformity or unnatural positioning of the thumb (sometimes visible) Limited or painful thumb movement Bruising or discoloration around the affected area Difficulty grasping or using the thumb normally

Diagnosis Path: Diagnosis involves a physical examination by a healthcare provider, who will assess the thumb’s appearance, the range of motion, and any deformity. X-ray imaging is typically used to confirm the dislocation and rule out associated fractures or injuries. It helps specify whether the dislocation is dorsal, volar, or involves other parts of the thumb joint, although in the case of unspecified dislocation, the exact location might not be detailed.

Treatment Protocols: Treatment aims to realign the thumb joint and promote healing. Common approaches include: - **Closed reduction:** A healthcare provider may gently manipulate the thumb back into position without surgery. - **Immobilization:** Using a splint or cast to keep the thumb stable during healing. - **Pain management:** Over-the-counter pain relievers or other medications as recommended. - **Rehabilitation:** Gradual exercises might be recommended post-immobilization to restore strength and flexibility. In cases where the dislocation is complex or cannot be realigned without surgery, open reduction and fixation may be necessary. Follow-up with a healthcare professional ensures proper healing and prevents complications such as chronic instability or arthritis.
