Study of Growth Plate Behavior in Children Undergoing Temporary or Permanent Hemi-epiphysiodesis or Epiphysiodesis Using Radiostereometric Analysis

What this Trial Is About

Researchers are studying how the growth plate behaves in children who have undergone temporary hemi-epiphysiodesis or epiphysiodesis, procedures used to treat limb length differences and axial deviations in the lower limbs. This observational study uses radiostereometric analysis RSA to accurately measure growth in three dimensions, helping to detect asymmetric growth and determine the best timing for implant removal. The study involves children treated with guided growth for axial deviations or temporary epiphysiodesis for limb length discrepancies. During surgery, small tantalum beads are implanted near the growth plate, allowing precise RSA imaging to monitor growth patterns during and after the procedures. This method offers microscopic accuracy in tracking changes over time. Participants will be monitored over a period of four years to observe growth plate behavior following surgery. The study includes regular follow-up imaging using RSA to measure growth in three planes. Researchers aim to gather detailed data on growth changes to improve treatment timing and outcomes for children with these conditions.
