mallet finger -doigt en mailletSometimes, a minor trauma can cause the extensor tendon of the distal joint of the finger to be ruptured resulting in a deformity called a Mallet finger.

Causes of mallet finger

The tendon becomes disconnected from the bone and can no longer extend the terminal joint of the finger.

Symptoms

The deformity is typical and is usually painless after a week or so.

Diagnosis?

An X-ray will rule out an associated fracture or joint damage.

Functional treatment

Surgery is not always required and splinting for six to eight weeks with the finger in extension can suffice to allow the tendon to heal in the proper position. Therapy is required after.

Surgery

Sometimes, surgery is preferred to repair the tendon or fix a fracture. Therapy will also be required to maximize recovery.
