NC54.5Z/S63.4 Traumatic rupture of ligament of finger at metacarpophalangeal or interphalangeal joint, unspecified



Traumatic rupture of a ligament of the finger at the metacarpophalangeal or interphalangeal joint is usually caused by a sudden, forceful impact such as a fall on the hand or a blow to the finger.


Diagnosis of traumatic ligament rupture of the finger is usually made through physical examination and X-ray imaging. Physical examination will usually reveal swelling, tenderness, deformity and/or reduced range of motion at the affected joint. X-ray imaging may also show a widened or dislocated joint, fractures, or avulsion fractures.

Differential diagnosis

Differential diagnosis of traumatic ligament rupture of the finger includes sprains, strains, fractures, and dislocations.


Treatment of traumatic ligament rupture of the finger depends on the severity of the injury. For minor injuries, rest, ice, compression, and elevation (RICE) can help reduce swelling and pain. For more serious injuries, immobilization with a splint or cast may be necessary to allow the ligament to heal. In cases of severe ligament rupture, surgical repair may be necessary.


The prognosis for traumatic ligament rupture of the finger is generally good, with a successful return to normal or near-normal range of motion and strength. The prognosis is better if treatment is started early, and if the injury was not severe.
