[Idiopathic toe walker child. Diagnosis and spontaneous evolution].

Aim Of The Study: To analyse the clinical, the aetiological aspects, the evolution without treatment and the age of correction.

Perthes' disease after the age of twelve years. Role of the remaining growth.

In order to define the prognostic factors in Perthes' disease in children older than 12 years, we reviewed 15 patients at the end of growth who were aged 12.1 to 14 years at presentation. The patients with the worst long-term prognosis (Stulberg class V) were compared with the others for age, skeletal maturity and remaining growth (Oxford method), as well as Catterall and Waldenström classifications at presentation.

The authors describe an iliac osteochondrosis in 98 teenagers aged of 12 to 17 years, responsible for anterior, medial or posterior pains of pelvis and the lumbar zone, squaring with the period of ossification of the iliac crest.

[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.
