S68.7

Clinical Causes: Workplace accidents involving machinery or tools Heavy objects falling onto the hand Motor vehicle collisions causing blunt or penetrating trauma Explosive blasts resulting in hand injuries Crush injuries from heavy equipment Acid or chemical burns leading to tissue destruction

Key Symptoms: Partial or complete loss of tissue in the hand's transmetacarpal region Bleeding and swelling at the injury site Presence of open wounds or severed tissues Severe pain at the time of injury, which may diminish as shock sets in Deformity or missing parts of the hand Reduced hand function, including grip and dexterity Possible infection signs if the wound is contaminated

Diagnosis Path: Diagnosis typically involves a physical examination to assess the extent of tissue loss and injury. Imaging studies such as X-rays are employed to determine the level of amputation, evaluate bone involvement, and check for associated fractures or foreign bodies. The healthcare provider will also evaluate for vascular and nerve damage and overall hand stability. Accurate assessment guides treatment planning and rehabilitation strategies.

Treatment Protocols: Treatment focuses on wound management, stabilization, and restoring as much function as possible. Approaches include: - Immediate first aid measures like controlling bleeding and preventing infection - Surgical intervention to clean the wound, repair tissues, or perform definitive amputation if necessary - Tetanus prophylaxis and antibiotics to prevent infection - Pain management - Referral to a rehabilitation team for physical therapy aimed at improving hand function - Use of prosthetics or assistive devices to enhance capabilities - Psychological support to cope with trauma and functional loss Long-term care may involve reconstructive procedures, adaptive devices, and occupational therapy to optimize recovery and daily functioning.
