Information provided by (Responsible Party):
University of Aarhus
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.

Condition Intervention
Pes Plano Valgus Flatfeet Procedure: Lateral lengthening osteotomy of calcaneus

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Calcaneal Neck Lengthening Osteotomy - Allogen Bone Graft Material Versus a Hydroxyapatite / β- Tricalcium Phosphate Bone Substitute

Primary Outcome Measures:
  • Healing of osteotomy [ Time Frame: 104 weeks ]
    Will be followed with repeated clinical examinations until healing

Estimated Enrollment: 10
Study Start Date: September 2010
Estimated Study Completion Date: April 2013
Estimated Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Pes plano valgus
Children with painful flatfeet
Procedure: Lateral lengthening osteotomy of calcaneus
Use of artificial bone graft
Other Name: Hydroxyapatite

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.
