Age-related changes in bone architecture.

Objective: : to evaluate the histologic and morphometric characteristics of bone biopsies of the anterior iliac crest of patients of different age groups.

Methods: : we studied 30 bone samples from the iliac crest, using brightfield optical microscopy. We divided the samples by donors' age groups in three groups: Group 1 (n = 10), subjects aged between 25 and 39 years; Group 2 (n = 10), subjects aged between 40 and 64 years; Group 3 (n = 10), individuals aged 65 years and over.
