Clinical Causes: Direct blow or trauma to the base of the thumb, often during sports activities, falls, or accidents Crushing injury to the hand Forceful twisting or levering of the thumb during a fall or contact sport Falling onto an outstretched hand with the thumb abducted

Key Symptoms: Pain around the base of the thumb, especially when moving or gripping Swelling and tenderness at the base of the thumb Bruising in the area Limited range of motion in the thumb and wrist Deformity or abnormal positioning of the thumb in severe cases Difficulty gripping or pinching objects Sensitivity to pressure at the fracture site

Diagnosis Path: Diagnosis of Bennett's fracture involves a combination of physical examination and imaging studies. A healthcare professional will assess the injury by checking for pain, swelling, and movement limitations. An X-ray is essential for confirming the presence of a fracture at the base of the first metacarpal, and multiple views may be taken to fully assess the fracture's extent and displacement. In some cases, additional imaging like CT scans might be recommended for detailed visualization, especially if surgical intervention is considered.

Treatment Protocols: Treatment options for Bennett's fracture depend on the severity and displacement of the fracture. Approaches include: - Non-surgical methods: In cases where the fracture is stable and minimally displaced, immobilization with a thumb spica cast or splint may be sufficient. This typically lasts for several weeks and aims to allow natural healing. - Surgical intervention: When the fracture is displaced or unstable, surgery is often necessary to realign the bone fragments. Procedures may include: - Closed reduction and percutaneous pinning, where pins are inserted through the skin to hold the bones in place. - Open reduction and internal fixation (ORIF), involving an incision to reposition the bones and secure them with screws, plates, or pins. Post-treatment care involves immobilization, pain management, and physical therapy to regain strength and mobility. Early intervention is crucial to prevent long-term joint issues such as arthritis or reduced thumb function.
