S63.233

Clinical Causes: Acute injuries from falls or direct trauma to the finger Sports accidents involving sudden twisting or grabbing motions Falling onto an outstretched hand with the finger extended Repetitive stress or overuse leading to joint instability Previous injuries or congenital conditions weakening joint structures

Key Symptoms: Pain localized around the PIP joint, especially during movement Swelling and tenderness in the affected finger A visible or palpable deformity or misalignment of the joint Reduced range of motion or difficulty bending or straightening the finger Sensitivity to touch and sometimes a clicking sensation when moving the finger

Diagnosis Path: To diagnose this condition, a healthcare provider performs a physical examination of the finger, assessing for swelling, deformity, and movement difficulty. Imaging studies, such as X-rays, are often used to confirm the subluxation, evaluate the extent of injury, and rule out associated fractures or damage to surrounding tissues.

Treatment Protocols: Treatment approaches focus on relieving pain, restoring proper joint alignment, and preventing future instability. Common methods include: - Immobilization with a splint or buddy taping to restrict movement and allow healing - Pain management with over-the-counter medications or as advised by a healthcare professional - Elevation of the finger to reduce swelling - Ice application to minimize inflammation - Physical therapy exercises to regain flexibility and strength after initial healing, under medical guidance - Surgical intervention is rarely needed but may be considered if the joint remains unstable or if there are associated fractures requiring fixation. Recovery time varies depending on the severity of the injury but generally involves several weeks of immobilization followed by rehabilitation.
