Area of Science:

  • Orthopedics
  • Pediatric Orthopedics
  • Radiology

Background:

  • Perthes disease affects the femoral head in children.
  • Early diagnosis is crucial for effective treatment.
  • Conventional radiography may show changes later in the disease progression.

Purpose of the Study:

  • To evaluate the utility of magnetic resonance imaging (MRI) in diagnosing and monitoring Perthes disease.
  • To determine if MRI can detect early infarction in the femoral head.
  • To assess the role of MRI in tracking the stages of healing.

Main Methods:

  • Retrospective analysis of 48 MRI scans from 16 children with Perthes disease.
  • Mean follow-up period of two years.
  • Serial MRI scans performed at six-monthly intervals.

Main Results:

  • MRI precisely identified the infarcted zone in the femoral head before radiological signs were apparent.
  • Early detection of infarction extent by MRI is beneficial for treatment planning.
  • Follow-up MRIs correlated with Catterall's classification stages of healing.

Conclusions:

  • MRI is a valuable tool for early diagnosis of Perthes disease.
  • MRI enables precise assessment of the extent of femoral head infarction.
  • Serial MRI monitoring aids in understanding and managing the disease progression and healing stages.
