Summary

Three-dimensional (3D) magnetic resonance (MR) imaging provides valuable preoperative insights for physeal bars. These 3D rendered and projection MR images significantly aid surgical planning for physeal bar excision.

Area of Science:

  • Orthopedic imaging
  • Pediatric radiology
  • Skeletal development

Background:

  • Physeal bars can lead to limb length discrepancies and angular deformities.
  • Accurate preoperative assessment is crucial for effective surgical intervention.

Purpose of the Study:

  • To evaluate the utility of 3D rendered and projection images from MR imaging in assessing physeal bars.
  • To determine if these advanced MR imaging techniques improve preoperative planning for physeal bar excision.

Main Methods:

  • MR imaging was performed on 15 patients with suspected physeal bars.
  • Both 2D and 3D gradient-echo sequences were utilized.
  • 3D rendered and projection images were generated from the MR data.

Main Results:

  • MR imaging findings significantly influenced surgical treatment decisions in 87% of patients.
  • A moderate or major effect on surgical planning was observed in 13 patients.
  • No instances of misleading MR imaging results were reported.

Conclusions:

  • MR imaging is a highly effective tool for visualizing physeal bars.
  • 3D rendered and projection physeal maps derived from MR data are particularly beneficial for preoperative planning.
