An observational study in Anisomelia and Deformity of Limb, sponsored by Oslo University Hospital. Recruiting at 1 site in Norway. Open to participants aged 3 Years to 16 Years. Per ClinicalTrials.gov, last updated 2025-09-04.
Sponsored by Oslo University Hospital · Observational
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.
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.
Oslo University Hospital is the lead sponsor of 810 studies on the registry; 148 are open to participants now.
