Brief summary

In a group of children with severe and painful flatfeet lengthening procedures of calcaneus can be indicated. In this study the investigators use an artificial bone graft technique to avoid removing bone graft from the iliac crest.

Detailed description

The aim is to study the clinical and radiological effects of calcaneal lengthening with either autogen bonegraft or a HA-βTCP graft material in a group of children with planovalgus. The hypothesis is that it is possible to achieve a stabile osteotomy with HA-βTCP graft material equal to the use of autogen bonegraft thus avoiding the need to obtaining iliac crest graft material at growing children.
