Mallet toe deformity

A mallet toe is a form of foot deformity where there is an isolated flexion deformity of the distal interphalangeal joint (DIPJ).


Mallet toe is often attributed to tightness in shoes. There is flexion of the DIPJ initially as a result of direct pressure from the shoe but eventually the flexor digitorum longus (FDL) tendon tightens and contracts, causing the deformity to be more permanent.


They may be associated with callosities on the tip of the toe and pressure on the nail.
