S65.515

Clinical Causes: Sharp object injury, such as a knife or glass cut Accidental trauma during activities like sports, gardening, or household chores Crushing injuries that cause deep cuts Industrial accidents involving machinery or tools Falls or collisions that impact the hand or finger

Key Symptoms: Visible bleeding from the laceration site Pain or tenderness in the affected finger Swelling or bruising around the injury Restricted movement or difficulty moving the finger Possible discoloration or numbness if blood flow is compromised Increased pain if infection develops Presence of a visible cut or tear in the skin over the finger

Diagnosis Path: Diagnosis typically involves a physical examination by a healthcare professional to assess the extent of the injury. They will evaluate the depth and length of the laceration,检查血液循环状态, and check for any signs of nerve or vessel damage. Sometimes, imaging studies like ultrasound or X-rays may be necessary if underlying bone or joint injury is suspected or to assess blood vessel integrity.

Treatment Protocols: Treatment strategies depend on the severity of the laceration. They usually include: - **Control of bleeding:** Applying direct pressure to stem bleeding. - **Wound cleaning:** Proper cleaning to remove debris and reduce infection risk. - **Stitches or sutures:** To close deep cuts and promote healing. - **Blood vessel repair:** If the vessel is severely damaged, surgical intervention may be required to restore blood flow. - **Tetanus prophylaxis:** Ensuring vaccinations are up-to-date, especially if the wound is contaminated. - **Antibiotics:** Prescribed if there's a risk of infection. - **Rest and elevation:** Keeping the finger elevated to reduce swelling. - **Follow-up care:** Monitoring for signs of infection or complications, and possibly physical therapy for mobility improvement if necessary.
