Extensor tendon injuries
Published in Peter Houpt, Hand Injuries in the Emergency Department, 2023
After treatment with a Stack splint, it is sometimes necessary to continue the treatment for a prolonged period if the patient is willing to. Ultimately, further recovery can occur in the course of one year. An extension deficit of less than 20° is not considered functionally disabling and does not require treatment. In a chronic mallet finger, a hyperextension of the PIP joint can occur, causing the finger to have a swan neck deformity.

A mallet finger is an injury to the extensor mechanism at the level of the DIPJ. Patients present with the DIPJ held in flexion due to the (newly unopposed) force exerted by the FDP tendon.

Shortening of the extensor tendon, adherence, postburn contractures proximal to the MCP joint cause inability to flex the MCP and PIP joint simultaneously. Individually, the MCP and PIP joint can be flexed but not together.Mallet finger

Mallet finger is a common hand injury involving the extensor tendon with either tendon rupture or bony avulsion at the base of the distal phalanx leading to limited active extension of the distal interphalangeal joint (DIP) [1–3]. The cause of mallet finger is usually forceful flexion or hyperextension to the tip of the finger [4–7]. Disruption of the terminal extensor tendon results in extension lag of the DIP joint and drop finger. If left untreated, a mallet finger can be complicated by the development of stiffness, osteoarthritis or swan-neck deformity [8–10].
