VELASQUEZ-FORERO, Francisco H.; JIMENEZ-BRAU, Daniel A.  y  ESPARZA-GARCIA, Mariela. Histomorphometric reference data of transiliac bone biopsy in children from 8 to 17 years old. Bol. Med. Hosp. Infant. Mex. [online]. 2018, vol.75, n.3, pp.135-144. ISSN 1665-1146.


Histomorphometric analysis of bone samples is a key tool for studying bone metabolism; however, only a few pediatric reference data exist. The aim of the present study is to report more reference data and to investigate if histomorphometric differences exist between age and gender.


We obtained 19 transiliac bone samples previously marked with tetracycline, from children between 8 and 17 years (13 were male), with normal blood test results and urine biochemical bone markers. We evaluated bone histomorphometric parameters using a digitalizing table with osteomeasure to obtain normative data of means and standard deviations, as well as median and range. Due to the small sample, a Monte Carlo simulation was applied. Structural, static, dynamic, and resorptic histomorphometric parameters were evaluated by age and gender following the American Society for Bone and Mineral Research recommendations.


Bone volume (in the older children) and mineral apposition rate (in the younger children), the eroded surface (in boys), and the new bone wall thickness (in girls) were significantly increased. On the trabecular area of mineralization front, the modeling and the remodeling bone formation were similar (16 and 18%). The rest of the histomorphometric bone parameters by age and gender showed no significant difference.


In healthy children, these bone histomorphometric findings, with these techniques and for this ages could be used as reference values.
