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.

Authors made a comparison between 167 suffers from Scheuermann's disease (SD), 70 adolescence idiopathic scoliosis (AIS) and 132 age, sex, height, weight, pubertal developmental stages (Tanner stages) matched controls. The height percentile in 130 cases was also determined. The bone mineral density (BMD) was measured by pQCT on the non dominate sided radial bone. The alkaline phosphatase (AP) level increased at the beginning of puberty and in the puberty in SD. In SD the trabecular Z-score of BMD was significantly decreased in Tanner stage 1 to 4 in both boys and girls. It was not found any significance difference, however, in Tanner stage 5, while in AIS girl no significance decrease of BMD was found. In SD good correlation could be demonstrated between increase in AP and decrease in trabecular Z score r = 0.2, while did not correlate with height percentile. The AP level's increase, and radiomorphometric data of SD severity (intervertebral space narrowing and antero-posterior diameter increase of vertebral body) shows a significant correlation with decreased trabecular Z-score in the period of prepuberty.

The development of kyphotic lesions in pigs with different weights from herds with a high frequency of the lesion was analysed pathologically, radiologically, and for alkaline phosphatase, calcium, magnesium, and phosphate in blood samples. The development of kyphosis was caused by the formation of ventral hemivertebrae due to the absence of ventral vertebral epiphyseal centres of ossification. Within the ventral parts of affected vertebral epiphyses, the retained chondroid tissue was dysplastic and the contents of cartilage canals with vessels often clotted with fibrin were reduced. As lesions such as fractures and inflammation that may be a secondary cause of kyphosis in pigs were absent and all blood parameters were within normal range, secondary causes of the condition, including metabolic disturbances, were excluded. It can be seen that the present type of porcine kyphosis does not develop until later in life as the ossification centres within the epiphyses of vertebrae have a retarded appearance. As the present porcine type of kyphosis pathomorphologically is comparable with Scheuermann's kyphosis in man, it constitutes a spontaneous model for this common cause of structural kyphosis of the thoracic or thoracolumbar spine.
