metaphyseal dysplasia

pathology

Quick Summary

Metaphyseal dysplasia is a rare, hereditary disorder affecting the growth zones of long bones, typically near the joints. The primary defect is in the bone's growth centers, leading to deformities. In this condition, the cortex of the shafts of long bones becomes thin and prone to fractures. While it can cause bone deformities, individuals with metaphyseal dysplasia may otherwise be healthy. This condition is distinct from familial hypophosphatemia, which primarily affects the kidneys.12
