S68.71

Clinical Causes: Industrial or workplace accidents involving machinery or heavy equipment Crush injuries from heavy objects or vehicles Severe falls resulting in hand trauma Violent assaults or stabbing injuries Electrical injuries leading to tissue necrosis Animal bites causing extensive tissue loss

Key Symptoms: Complete loss of part of the hand at the transmetacarpal level Severe bleeding at the injury site Exposed bones, tendons, and tissues Swelling around the affected area Loss of hand function and mobility Pain at the injury site, which may vary from severe to minimal depending on nerve damage Possible shock or systemic symptoms if bleeding is significant

Diagnosis Path: Diagnosis involves a physical examination by a healthcare professional, assessment of the injury and extent of tissue loss, and imaging tests such as X-rays. X-rays help determine the extent of bone injury or fracture, confirm the level of amputation, and assess any associated damage to surrounding bones and structures. The clinical history of the injury also provides insights into the mechanism and severity, aiding in treatment planning.

Treatment Protocols: Treatment strategies focus on stabilizing the patient's condition, controlling bleeding, preventing infection, and addressing the amputated tissue. Typical approaches include: - Emergency care with hemorrhage control and wound stabilization - Surgical management to close or prepare the remaining tissue for reconstruction - Replantation is rarely feasible at this level but may be considered in specific cases with immediate access to specialized surgical teams - Reconstruction procedures, including skin grafts or flap surgeries, to promote healing and restore function - Postoperative rehabilitation, including physical therapy and occupational therapy, to regain as much hand functionality as possible - Psychological support to address emotional and mental health needs following such traumatic injuries
