S66.129

Clinical Causes: Sharp objects such as knives, glass, or metal tools Accidental cuts during daily activities or work tasks Crush injuries that cause tearing of tissue Falls or trauma that result in a sudden cut or puncture Bite wounds from animals Surgical injuries during medical procedures

Key Symptoms: Pain and tenderness at the injury site Swelling around the finger and wrist Difficulty bending or flexing the affected finger Visible bleeding or open wound Numbness or tingling in the finger Reduced grip strength and hand dexterity Possible deformity if the injury is severe Bruising or discoloration around the injured area

Diagnosis Path: To assess the injury, healthcare providers will perform a physical examination, inspecting the wound and checking for movement and sensation in the affected finger. Imaging tests such as X-rays may be ordered to detect any associated fractures or to evaluate the extent of soft tissue damage. A thorough assessment helps determine whether surgical intervention is necessary to repair torn tendons or muscles.

Treatment Protocols: Managing a flexor tendon laceration typically involves medical procedures to restore hand function. Treatment options may include: - **Wound Cleaning and Closure:** Proper cleaning to prevent infection followed by stitches or other closure techniques. - **Tendon Repair Surgery:** In cases where tendons are torn, surgical repair is often required to reattach and restore movement. - **Immobilization:** The hand and finger may be immobilized using splints or casts to promote healing. - **Antibiotics:** To reduce the risk of infection, especially if the wound was caused by a contaminated object. - **Rehabilitation:** Physical therapy and hand exercises are essential post-repair to regain strength and flexibility. It is important to seek prompt medical attention to optimize recovery outcomes and decrease the risk of long-term functional impairment.
