Effect of diclofenac on fixation of hydroxyapatite-coated implants. An experimental study.
We studied the effect of non-steroidal anti-inflammatory drugs on the fixation of hydroxyapatite-coated implants. Cylindrical plugs of pure titanium, coated with hydroxyapatite (HA), were inserted into both femora of 10 adult rabbits, 5 of which received 7 daily doses of 30 mg diclofenac. Three weeks after implantation the interface strengths were measured by the pull-out test. The mean peak force for the diclofenac-treated group was 290 +/- 57 N compared with 369 +/- 37 N for the control group (p < 0.025). We conclude that the inhibitory effect of diclofenac on bone repair is not neutralised by HA-coating of an implant.
