Scheuermann's kyphosis: a form of osteoporosis?

A high frequency of abnormalities were noted in radiographic measurements of bone density, microradiography of the iliac crest, serum alkaline phosphatase, urinary hydroxyproline and dietary calcium intake in 12 patients with Scheuermann's juvenile kyphosis. Scheuermann's kyphosis may be a manifestation of generalized skeletal disease which becomes symptomatic during the growth spurt of puberty.
