Mallet finger, also known as "baseball finger," is an injury to the thin tendon that straightens the end joint of a finger or thumb. The injury results when an unyielding object (like a ball) strikes the tip of the digit and forces it to bend further than it is intended to go.

Mallet finger injuries are named for the resulting flexion deformity of the fingertip, which resembles a mallet or hammer. Mallet finger injuries are caused by the disruption of the extensor mechanism of the phalanx at the level of the distal interphalangeal joint, usually due to a forced flexion at the distal interphalangeal joint.

Mallet finger is the term applied to extensor avulsion fractures or distal extensor tendon ruptures. Either one results in an inability to extend the distal interphalangeal (DIP) joint. Mallet finger injuries are [1]: Caused by the disruption of the extensor mechanism of the phalanx at the level of the distal interphalangeal joint.

A mallet finger, also known as hammer finger or PLF finger or Hannan finger, is an extensor tendon injury at the farthest away finger joint. [2] This results in the inability to extend the finger tip without pushing it. [3] There is generally pain and bruising …

2023年8月7日 · Two types of injury can occur: A tendinous mallet involves rupture of the extensor tendon proximal to the DIP joint.
