Lumbar spine radiographs of 17 adult patients with hypophosphataemic vitamin D-resistant rickets (HPR) were examined and measured in their anteroposterior and transverse dimensions. Comparison of these measurements with those of a group of normal subjects showed the HPR patients to have narrower spinal canals in both diameters. No difference was found between men and women in either group. The lumbar spinal canal stenosis in adult HPR patients may make them more susceptible to spinal cord compromise from space-occupying lesions within the canal, causing back pain and lower limb weakness for which surgical intervention may be indicated.
