OBJECTIVE: To determine the degree of delayed skeletal maturity in patients with active Legg-Calvé-Perthes disease (LCPD) with radiographic evaluation of bone age and the degree of fragmentation of the femoral head using the modified lateral pillar Herring classification.
MATERIAL AND METHODS: Twenty patients with LCPD were studied with left hand and wrist anteroposterior simple X- rays to determine bone vs. chronologic age. They were also studied with anteroposterior pelvis simple X-rays to determine the modified lateral pillar Herring classification.
RESULTS: Seventeen (17/20) patients with LCPD presented with chronologic mean age of 8.15-years-old in comparison to mean bone age of 6.62-years-old (delay in bone age of 22.89 months). We found a delay in bone age; mean of 28 months in children 6 to 10-years-old, mean of 8 months in children 10 years and older by quadratic regression.
DISCUSSION: Previous series report patients with LCPD delayed bone age of 22 months. Our report present a series with delayed in bone age of a mean of 28 months, in children with LCPD of 6- 10-years-old.
CONCLUSIONS: The degree of delayed bone age in LCPD, in our Mexican population is of 28 months in children 6- 10-years-old, and only 8 months in children ten-years-old.
