S63.421

Clinical Causes: Direct injury from a blow or crush to the finger Sudden forceful bending or hyperextension of the finger Sports injuries involving finger trauma Accidental jams or impacts during activities like gardening, carpentry, or manual labor Falls or accidents that forcefully bend the finger backward

Key Symptoms: Pain at the affected joint, which may worsen with movement or touch Swelling around the finger joint Tenderness along the palm side of the finger Bruising or discoloration near the injury site Limited or decreased range of motion, especially when trying to straighten or bend the finger A feeling of instability or looseness in the finger joint Possible deformity if the ligament rupture is severe

Diagnosis Path: Diagnosis involves a thorough physical examination by a healthcare professional, who will assess for swelling, tenderness, and joint stability. Imaging tests such as X-rays may be ordered to rule out fractures or dislocations. Although X-rays don't show ligament tears directly, they help exclude other possible injuries. In some cases, MRI scans might be used to visualize soft tissue damage, including ligament ruptures.

Treatment Protocols: Treatment options depend on the severity of the ligament tear. They may include: - Rest and immobilization: Using a splint or buddy tape to keep the finger still and promote healing - Ice application: To reduce swelling and pain - Pain management: Over-the-counter medications like acetaminophen or NSAIDs - Physical therapy: To restore movement and strengthen the finger after initial healing - Surgical intervention: May be necessary for complete ruptures or if the ligament cannot heal properly on its own. Surgery involves repairing or reconstructing the torn ligament to restore finger stability. Recovery time varies based on the injury's severity, generally ranging from a few weeks to several months, with proper follow-up and adherence to treatment plans.
