Abstract

Symptomatic osteodystrophy is uncommon in patients on RDT in Birmingham, it appears late and is associated with pronounced osteitus fibrosa. In Newcastle osteodystrophy is common and severe; it appears earlier and is associated with multiple fractures but not accompanied by radiological evidence of osteitis fibrosa. These differences cannot be explained by variations in exposure to fluoride but a pilot study suggests that some solute in the tap water may be responsible.
