Mallet finger with distal interphalangeal joint subluxation
Mallet finger with distal interphalangeal joint subluxation
Mallet fractures result from sudden forced flexion of an extended distal interphalangeal (DIP) joint, resulting in avulsion of the attachment of the extensor tendon. If subluxation of the DIP joint is present as shown here, the patient may need open reduction and should be referred to a hand surgeon within two to three days.
