Pediatric Radiology > Musculoskeletal > Metabolic Diseases > Rickets
Rickets is a metabolic abnormality in which a deficiency of Vitamin D leads to failure of normal bone mineralization. This disease is manifested earliest at the sites of rapid growth, namely the knees and wrists. Common causes of rickets include: 1) nutritional (dietary insufficiency), 2) malabsorption, 3) renal disease, or 4) increased requirement for vitamin D.
Patients may be susceptible to slipped capital femoral epiphyses as well as pathologic fractures.
Rickets in a 2-year-old female. AP radiograph of the knees demonstrates widened growth plates and frayed metaphyses. Also note the bowing of the long bones (tibia and fibula bilaterally).
|Rickets in a 5-year female. Radiograph of the left wrist reveals widened physes. The distal ulnar and radial metaphyses appear cupped and frayed.|
