The use of demineralized xenogeneic bone implants to correct phalangeal defects: a case report.

Demineralized bovine bone blocks and powder were used to reconstruct phalangeal defects created by excision of bulging endochondromas . Bony reconstruction was documented by roentgenography at 9 weeks and by biopsy at 7 months. Follow-up at 22 months has shown stability of the implants, further ossification, and no recurrence of the phalangeal endochondromas . The use of xenogeneic demineralized bone implants promotes induced osteogenesis and rapid healing, avoids harvesting procedures, and offers a potentially unlimited supply of banked material.
