Failure of Bone Resorption in a Calf

Abstract

A case report of an anomaly of bone in a newborn calf is presented. The calf had solid bones, devoid of marrow cavities, in the limbs. The solid tissue was mainly unremodelled endochondral bone with some periosteal bone also present. The defect appeared to be a failure in the ability to resorb bone. It resembled, grossly and microscopically, similar conditions which occur as genetic defects in mice, rats and rabbits.
