- Rickets results from deficient mineralization of normal osteoid and interruption of the normal orderly development and mineralization of growth plates.
- Vitamin D–resistant (hypophosphatemic) and nutritional rickets are the most common types.
- Radiologic changes in rickets occur predominantly at sites of rapid growth, including the proximal humerus, distal radius, and distal femur and both ends of the tibia.
- Treatment is dietary and medical.
 Imaging Findings
 Plain films
- Predominant changes are metaphyseal, with widening of the zone of provisional calcification due to the presence of unmineralized osteoid.
- Cupping, fraying, and splaying of metaphyses occurs with growth and continued weight bearing.
- Bowing of long bones
