Forty patients with bone defects suffering from tuberculosis benign tumors,
traumas, and congenital deformities were treated with porous biphasic cera
mics (HA-TCP). The defects were replaced by blocks or granules of HA-TCP fo
llowing the removal of pathological foci. In all cases, clinical signs disa
ppeared postoperatively, and excellent function was obtained. X-ray films s
howed good fusion between host bones and substitutes. No loosening of ceram
ic implants or recurrence of the original disease was observed.
