Official title
Behaviour of the Growth Plate in Patients Operated With Either Permanent or Temporary Hemi-epiphysiodesis or Epiphysiodesis Through by the Use of Radiostereometric Analysis (RSA)
Overview
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
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.
Interventions
- Other Temporary hemi-epiphysiodesis or epiphysiodesis
Tension band plate (eight-plate, pedi plate), staple or locking plate
Primary outcome measures
- Behaviour of the growth plate during and after temporary hemi-epiphysiodesis and epiphysiodesis [Time frame: 4 years]
Eligibility criteria
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
Exclusion criteria
- Children with axial deviations and pathological physis
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
