title: [Elongation with callotaxis for congenital brachymetatarsia].
abstract: OBJECTIVE
  To present 10 cases of congenital brachymetatarsia treated with elongation by means of callotaxis with external minifixators.
  
  
  BACKGROUND
  Brachymetatarsia of one or more of the matatarsals involving one or both extremities is a congenital condition, more frequent in the right foot, with the 4th metatarsal most commonly affected.
  
  
  METHODS
  From May 2007 to September 2008, 7 patients with congenital brachymetatarsia, ages 8 to 15 years, were operated on. Two metatarsals were involved in 3 of them and thus the series included 10 procedures. All of them underwent lengthening through callotaxis with a monoaxial external mini-fixator.
  
  
  RESULTS
  Mean lengthening was 21.1 mm, with a range of 17 to 25 mm. The complications included two cases of lengthening regression of 5 mm each. Delayed healing was reported in one of these two cases, and healing occurred spontaneously at 6 months. Nine metatarsals healed without any problems; no infections or material intolerance occurred.
  
  
  CONCLUSIONS
  Lengthening of metatarsals through callotaxis with external mini-fixators is an appropriate procedure for pediatric and adolescent patients with congenital brachymetatarsia.
