Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

By using radiostereometric analysis (RSA) we will be able to study growth during and after temporary epiphysiodesis and with great accuracy be able to detect asymmetric growth following this procedure.

By using the same method we also want to analyse patients with axial deviations operated with guided growth (tension band plating) to study the growth during and after the procedure and be able to set the correct timing for removal of the implant.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The RSA method consists of implantation of small tantalum beads on either side of the physis during surgery on the the physis. Later analysis of the RSA Pictures with the RSA-method will give us an microscopically accurate measure of the growth in three planes.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Children with idiopathic axial deviations in the lower extremities
* Children with limb length discrepancys where timing of epiphysiodesis is difficult because of a big discrepancy in skeletal age and chronological age
