Faster integration of human allograft bone than of the bovine substitute Lubboc: non-randomized evaluation of 20 cases with benign tumors or tumor-like conditions.

In 20 patients, we studied healing and time for complete integration of human cancellous bone allografts and the bovine substitute Lubboc plain radiographs. They were all operated on because of benign tumors or tumor-like conditions, and followed until integration of the graft or for at least 1 year after operation. The median follow-up was 10 (2–40) months. Allografts showed a better integration than the bovine substitute. We conclude that allografts are to be preferred for these indications.
