Official Title: Calcaneal Neck Lengthening Osteotomy - Allogen Bone Graft Material Versus a Hydroxyappatite / β- Tricalcium Phosphate Bone Substitute
Brief Summary: In this foot deformity (plano valgus) surgery may be indicated. The deformity is corrected with an osteotomy at the heelbone. In most cases bone graft material has to be obtained from the iliac crest to support the osteotomy. In the planned study a group of children will be operated with an artificial bone graft material and thus avoiding the need harvesting of bone graft at the iliac crest.
