Abstract:
A total of 16 metatarsal bones were treated for ten with brachymetatarsia using two different methods: single staged lengthening by bone graft(2 cases) and gradual distraction lengthening using unilateral external fixator(14 cases). Three cases of first metatasal bone and thirteen cases of fourth metatarsal bone were operated. All of the cases of the brachymetatarsia were congenital. The average amount of lengthening was 16.1 mm in gradual distraction lengthening while 10.5mm in single staged lengthening. Average percentile increase was 38.8% in gradual distraction lengthening and 23% in single staged lengthening. The average healing index of gradual distraction lengthening was 1.7(months/cm). Although single staged lengthening has advantage of cosmetics, gradual distraction lengthening using unilateral external fixator was thought to be effective functionally for metatarsal lengthening.
