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.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
