Although bone wax is often used as a hemostatic agent for bone in surgery, some problems in biocompatibility have been pointed out. Therefore, we have evaluated hydroxyapatite-putty (HAP-putty) as a hemostatic agent for bone. Adhesive strength of HAP-putty to bone increased with the amount of sodium alginate, reaching maximum value in case of containing 8% sodium alginate. An actual hemostatic ability of HAP-putty was evaluated using rabbits. Bleeding from bone was arrested within 3 minutes. Thus, HAP-putty showed excellent hemostatic ability. Soft tissue response to HAP-putty was evaluated in rabbit subcutaneous tissue. Histological observation revealed slight inflammatory response around HAP-putty. HAP-putty partially transformed to HAP 24 hours after the implantation. In conclusion, HAP-putty could be a useful hemostatic agent for bone due to its good hemostatic ability and excellent biocompatibility.
