Brachymetatarsia

Dr Henry Knipe and Dr Andrew Dixon et al.

Brachymetatarsia (a.k.a. congenital short metatarsus) is a rare condition that develops from early closure of the growth plate. 

Females are almost exclusively affected 1

It typically involves the fourth ray or, less frequently, more than one metatarsal bone. Supernumerous sesamoids at the metatarsophalangeal joints are most common in the fifth ray and least common in the fourth ray. The incidence in the first interphalangeal joint is 2% 2.

Brachymetatarsia can be related to several genetic conditions and syndromes:

There are several types of lengthening procedures which can be performed. 

For metatarsals that only need to be lengthened up to 15 mm, single-stage lengthening procedures with a variety of biologic and synthetic implants are preferred, whereas gradual lengthening allows for greater length gain and concomitant lengthening of the soft tissues.
