Conditions pes plano valgus, flatfeet
Treatment lateral lengthening osteotomy of calcaneus
Sponsor University of Aarhus
Start date September 2010
End date October 2012
Trial size 10 participants
Trial identifier NCT01618812, M-20090162


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.

Additional Information

Official title Calcaneal Neck Lengthening Osteotomy - Allogen Bone Graft Material Versus a Hydroxyapatite / β- Tricalcium Phosphate Bone Substitute
Principal investigator Martin Gottliebsen, PhD-student
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.
