[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.
