Current concepts: mallet finger - PMC - PubMed Central (PMC)
Soft tissue mallet finger is the result of a rupture of the extensor tendon in Zone 1, and a bony mallet finger is the result of an avulsion of the extensor tendon from the distal phalanx with a small fragment of bone attached to the avulsed tendon.
Mallet Finger And Other Finger Extensor Injuries - OrthoPaedia
When there is bony involvement of the distal phalanx, the injury is referred to as a "bony mallet." An injury to the extensor digitorum more proximally, at the level of the middle phalanx, damages the so-called “central slip” and can lead to a boutonnière (meaning "button hole" in …
