Qualitative and quantitative evaluation of avian demineralized bone matrix in heterotopic beds

Abstract

Objective: To evaluate the osteogenic potential of avian demineralized bone matrix (DBM) in the context of implant geometry. Study Design: Experimental. Animals: Rock pigeons (n=24). Methods: Tubular and chipped forms of DBM were prepared by acid demineralization of long bones from healthy allogeneic donors and implanted bilaterally into the pectoral region of 24 pigeons. After euthanasia at 1, 4, 6, 8, 10, and 12 weeks, explants were evaluated histologically and compared by means of quantitative (bone area) and semi quantitative measures (scores). Results: All explants had new bone at retrieval with the exception of tubular implants at the end of week 1. The most reactive part in both impla..
