MALLET FINGER

 

 

•Fractures of the Distal Phalanges. Four types of fracture occur: transverse, longitudinal, comminuted, and chip.

•Chip fractures involve the posterior or anterior corners at the phalangeal base. A posterior chip fracture inactivates extension of the distal interphalangeal joint and produces a flexion deformity (mallet or baseball finger).

 

COMPLICATIONS: 

•Dorsal ulceration ,nail deformities , and maceration of skin

•Swan neck deformity
