[Supramalleolar derotation osteotomy for torsion of the leg in children and adolescents. Techniques and results: apropos of 22 patients (32 legs)].

We have performed 32 supramalleolar osteotomies described by Mc Nicol to correct excessive internal or external tibial torsion in 22 patients (aged from 4 to 8 years, with different indications, with a follow-up of 16 months to 7 years). The consolidation of the osteotomy was obtained in 6 weeks. Eighteen patients (27 osteotomy) have a good result, 2 results are fair and 2 patients have a poor result. The indications for correction of excessive internal or external tibial torsion are very uncommon, and reserved to cases with functional disorbility of fitting appliances, or unaesthetic or uncomfortable gait.
