On the linear sizes of vertebrae and intervertebral discs of children in the beginning of puberty

STUDY DESIGN: We collected experimental data concerning vertebrae sizes and performed an investigation of these data for different patient ages by methods of mathematical statistics. PURPOSE: The standard dimensions of vertebrae and intervertebral discs are of major importance for obtaining a comprehensive understanding of spine diseases and their successful treatment. The purpose is to study these sizes for children at the age of 9–14 years. OVERVIEW OF LITERATURE: Unfortunately, this issue is poorly presented in the corresponding literature. There are no systematic results. Only particular cases are presented. MATERIALS AND METHODS: Experimental is based on the: results of X-ray investigations of children spines. Theoretical background is given by methods of mathematical statistics. RESULTS: Systematic description of vertebrae sizes for children of age 9–14 is given. This specific age interval is the most common period of initiation of various pathological deformations of human spine. CONCLUSIONS: The acquired data both reflect the process of spine growth and can serve for building correct mathematical models of a healthful or diseased spine.
