title: [Bone lengthening of congenitally short metacarpus and metatarsus by the callus distraction technique].
abstract: OBJECTIVE
  We evaluated the results of lengthening of congenitally short metacarpus and metatarsus by the callus distraction technique.
  
  
  METHODS
  We treated congenitally short metacarpus (n=7) and metatarsus (n=4) of five patients (4 females, 1 male; mean age 15 years; range 10 to 21 years) by callotasis. Callus distraction was performed with the use of mini-Orthofix or Ilizarov type semicircular external fixators. The distraction rate was 0.25x2 mm/day for both types. The mean follow-up period was 23 months (range 12 to 33 months).
  
  
  RESULTS
  The mean metacarpal and metatarsal lengthenings were 20 mm (range 15 to 25 mm) and 25 mm (range 20 to 30 mm), respectively. The mean healing index was 1.4 months/cm for metacarpal lengthening, and 1.8 months/cm for metatarsal lengthening. No neurovascular complications were encountered. One patient required autogenous fibular grafting for union. Pin tract infections were found in three patients. The overall complication rate was 36%.
  
  
  CONCLUSIONS
  Callotasis is an effective and reliable method for lengthening of short metacarpal and metatarsal bones. In addition, it preserves the periosteal bone tissues, which has a favorable effect on the duration of treatment.
