[Filling up small bone defects with bone ceramics (hydroxylapatite)].

First clinical results using a bovine hydroxyapatite implant to fill up small bony defects after excision of enchondromas or cysts are reported in twelve patients. Incorporation without any problems was completed radiologically after six to eight weeks. Complications did not occur. Avoiding additional surgery harvesting cancellous bone chips at the iliac crest, the use of these bovine hydroxyapatite ceramic seems to be reasonable.
