Renal failure in children is associated with a wide range of musculoskeletal disorders such as osteonecrosis, stress fractures, brown tumours, epiphysiolysis, joint infections and angular deformities. In this paper the authors report their experience concerning the surgical treatment of the angular deformities of the lower limbs in renal osteodystrophy (RO).

Between 1995 to 2003, 10 children (five girls and five boys) with RO underwent surgical correction of angular deformities of the lower limbs. Of these, seven had femoral osteotomies because of knee deformities (three genu valgum, four genu varum) and three had osteotomies because of tibial angular deformity. The average age at surgery was 5 years (min. 2 years, max. 12 years). Different types of osteosynthesis were used (staples and cast, Ortho-fix and Ilizarov frames) according to the age of the child and the degree and the site of the angular deformities.

All osteotomies healed without complications and the surgical correction was considered appropriate at the end of treatment. At an average follow-up of 4.5 years there was no significant relapse and no need for second surgery.

Simple osteosynthesis (staples and cast) was most appropriate in the youngest children and in mildest deformities (particularly at the distal tibial metaphysis). External devices were more suitable in the oldest children and for genu valgum/varum deformities. To optimise the time of consolidation close collaboration with the paediatricians is required in order to perform surgery under the best metabolic conditions (elevation of the serum alkaline phosphatase concentration above 500/l is a good marker of bone metabolic healthy).
