To evaluate whether acetabular retroversion is present early in Legg-Calvé-Perthes disease or develops over time as a secondary consequence of femoral head deformity.
Reviewed 53 hips from 44 children with Legg-Calvé-Perthes disease (LCPD) who underwent axial imaging before triradiate cartilage closure, using 35 unaffected contralateral hips as internal controls.
Measured acetabular version on axial cuts across disease severity groups (Herring A/B, n=42 vs Herring B/C or C, n=11).
Assessed final anteroposterior pelvic radiographs for crossover signs to detect acetabular retroversion in 16 hips followed past skeletal maturity.
Before skeletal maturity, acetabular retroversion was rare (1.8%), with no significant difference between LCPD hips (13.6 ± 4.3 degrees) and unaffected hips (15.4 ± 5.4 degrees).
Hips with more severe femoral head involvement (Herring B/C or C) had significantly more relative retroversion than milder cases (10.8 degrees vs 14.6 degrees, P = 0.047).
Among hips followed past skeletal maturity, 5 of 16 demonstrated crossover signs, yielding a 31% prevalence of acetabular retroversion.

Implication

Case-control study observes that acetabular retroversion develops over time alongside femoral head deformity in children with Legg-Calvé-Perthes disease, suggesting an acquired structural consequence.
