S68.021

Clinical Causes: Work-related accidents involving machinery or tools Falls or crush injuries in industrial settings Car or motorcycle accidents Any high-impact trauma that causes a partial detachment or severance of the thumb Industrial or construction site incidents

Key Symptoms: Severe pain at the site of injury Bleeding from the injury site Visible partial loss of the thumb, with edges of tissue torn or cut Swelling and bruising around the affected area Impaired thumb movement or function Possible exposure of bone or tissue if the injury is deep Numbness or tingling if nerves are affected

Diagnosis Path: Diagnosis typically involves a physical examination of the hand and thumb, assessing the extent of tissue loss and damage. Imaging tests such as X-rays are commonly used to determine if bone structures are involved, to evaluate the injury's severity, and to plan treatment. The healthcare provider will also review the patient's medical history and the circumstances of the injury.

Treatment Protocols: Treatment options may vary depending on the extent of the injury but generally include: - **Initial Care:** Applying pressure to control bleeding, cleaning the wound to prevent infection, and immobilizing the hand. - **Surgical Intervention:** Possible procedures include wound closure, tissue reconstruction, or amputation of non-viable tissue. - **Rehabilitation:** Physical therapy to restore hand strength and movement, and to adapt to changes resulting from the injury. - **Prosthetic Fitting:** In cases where amputation significantly affects function, a thumb prosthesis might be recommended. - **Pain Management:** Use of medications to manage discomfort during recovery. Long-term recovery depends on the injury's severity, promptness of treatment, and rehabilitation efforts.
