Mallet Finger

This is a flexion deformity affecting the distal interphalangeal joint

of the finger and is due to either distal extensor tendon rupture or

avulsion with a bony fragment after traumatic forced flexion of the

extended finger tip. The resultant weakness is often painless and

presents with an inability to actively extend the fingertip.

Non traumatic mallet finger occurs more often in diabetics.

Treatment is usually by splinting the distal interphalangeal joint in extension

Surgery is rarely required.
