S63.423

Clinical Causes: Direct trauma to the finger, such as a crushing injury or a blow from an object Sports injuries involving forceful impact or sudden bending of the finger Falling onto an outstretched hand, causing bending and tearing of the ligament Accidental jamming or pinching of the finger during activities or work tasks

Key Symptoms: Severe pain at the site of injury, especially when moving the finger Swelling and tenderness over the affected joints Bruising or discoloration around the finger Limited range of motion or stiffness in the middle finger A sense of instability or abnormal movement in the finger Possible deformity or dislocation if the injury is severe

Diagnosis Path: Diagnosis typically involves a thorough physical examination by a healthcare provider, who will assess the finger's stability, range of motion, and tenderness. Imaging tests such as X-rays may be used to rule out associated fractures or dislocations. In some cases, magnetic resonance imaging (MRI) can provide detailed images of soft tissue damage, confirming the rupture of the palmar ligament.

Treatment Protocols: Treatment options depend on the severity of the rupture. Common approaches include: - Rest and immobilization using a splint or buddy taping to prevent further injury and facilitate healing - Ice application to reduce swelling and pain - Nonsteroidal anti-inflammatory drugs (NSAIDs) to manage inflammation and discomfort - Physiotherapy and hand exercises to restore function and strength once healing progresses - Surgical intervention may be necessary in cases of complete ligament rupture or significant joint instability, involving repair or reconstruction of the ligament Recovery times vary, with minor injuries healing in a few weeks, while more severe cases may require several months and specialized rehabilitation.
