The histologic features of bone callus after a traumatic fracture in a patient with osteopetrosis are presented. The fracture callus develops in stages that are apparently normal. The tissue is initially rich in bone-forming cells and vessels. One year later, however, unlike mature osteopetrotic bone, the tissue shows no Haversian organization.
