S66.322

Clinical Causes: Sharp objects such as knives, glass, or metal cutting the skin and underlying tissues Accidents involving machinery or woodworking tools Trab or fall injuries that result in deep cuts on the hand or wrist Crushing injuries that cause tearing of the extensor tendons and surrounding tissues Violent instruments or tools used improperly during daily activities

Key Symptoms: Visible cut or laceration on the back of the middle finger, wrist, or hand Swelling and tenderness around the injury site Inability or difficulty in extending the middle finger Pain at the site of injury, particularly when trying to straighten the finger Bruising or discoloration around the injury area Possible bleeding or oozing from the wound Limited movement or deformity of the finger if tendons are severely damaged

Diagnosis Path: Medical evaluation involves a physical examination of the hand and finger, focusing on the extent of tissue damage and finger movement. The healthcare provider may perform specific tests to assess tendon function, such as asking the patient to extend the finger against resistance. Imaging tests like ultrasound or MRI may be employed to visualize the injury's depth and confirm the extent of tendon and fascia involvement. Prompt diagnosis aids in planning appropriate treatment to restore hand function.

Treatment Protocols: Cleaning the wound thoroughly to remove debris and reduce infection risk Suturing or stitching the laceration to close the skin Surgical repair of damaged tendons and fascia if necessary Immobilization of the finger with splints or bandages to promote healing Pain management using prescribed medications Rehabilitation exercises following wound healing to regain finger movement and strength Monitoring for signs of infection or complications during recovery
