Summary

This study details acetabular changes in Perthes' disease in Indian children, finding osteoporosis and contour irregularities. These changes, linked to disease severity and age, were also observed in adult hips and correlated with outcomes.

Area of Science:

  • Pediatric Radiology
  • Pediatric Orthopedics

Background:

  • Perthes' disease is a hip condition affecting children.
  • Acetabular changes are a key feature of Perthes' disease.

Purpose of the Study:

  • To identify and characterize acetabular changes in Indian children with Perthes' disease.
  • To compare these changes with those in other populations and age groups.
  • To investigate the pathogenesis and prognostic implications of acetabular changes.

Main Methods:

  • Radiographic analysis of 155 Indian children with Perthes' disease.
  • Comparison with radiographic data from 25 children from Liverpool and 24 adult hips.
  • Radio-isotope hip scans in 27 children to assess vascularity.

Main Results:

  • Identified acetabular changes include osteoporosis, contour irregularity, premature triradiate cartilage fusion, cartilage hypertrophy, and dimensional alterations.
  • Changes were more pronounced in older children and with greater femoral epiphysis involvement.
  • Increased acetabular radio-isotope uptake indicated heightened local vascularity and metabolic activity.

Conclusions:

  • A working model for the pathogenesis of acetabular changes in Perthes' disease was proposed.
  • Statistical correlations suggest these acetabular changes significantly influence the final outcome of the disease.
