Q: What are the skull & spine changes in Rickets?

A: With treatment, there is regression of radiological findings seen in Rickets. During a stage of healing, there is extensive periosteal new bone formation as a reflection of ossification occurring along the cornices of diaphyses. Also seen during healing are radiolucent bands at metaphyses of long bones & cupping of metaphyses becomes clearly prominent. As healing progresses remodeling of bowing deformities occur & in skull characteristic bossing of frontal & parietal bones becomes apparent with premature closure of sutures.

With Renal Tubular acidosis, a peculiar brush border along the metaphysis is seen in the healing phase
