title: Lengthening of congenital limb length discrepancy using callotasis: early experience of the Hospital for Sick Children.
abstract: Seventeen patients were reviewed after callotasis lengthening for congenital limb length discrepancy. The average age at lengthening was 10.8 years. Length discrepancy before lengthening ranged from 4.5 cm to 12 cm for the leg, and 24 mm to 30 mm for the forearm. At completion of the lengthening process, all but one patient had their discrepancy corrected successfully. The difficulties encountered were classified into problems, obstacles and complications. All patients suffered from superficial infection, but in only one case did this become a complication, resulting in a residual femoral discrepancy of 2 cm. Of the other three patients who suffered a complication, one fractured through the newly formed bone. The fracture was treated conservatively. In two further femoral lengthenings, the fixator had to be exchanged under general anaesthesia because it had reached its maximum excursion. Callotasis appears to be a safe and reliable method for correcting congenital limb length discrepancy in children.
