摘　　要：可吸收骨折内固定材料要求具有较高的初始强度及良好的生物相容性。对自行研制的可吸收羟基磷灰石/聚DL-乳酸(HA/PDLLA)复合骨折内固定材料进行骨内植入实验。大体观察结果表明:HA/PDLLA 材料强度良好,周围无明显的炎性反应。结论:HA/PDLLA复合材料强度较好,适用于松质骨骨折的固定, 且生物相容性良好。Higher incipient intensity and favorable biocompatibility were imperative to the bone internal fixation material. In this article, the bone implant test was carried out to evaluate the self-designed absorbable Hydroxyapatite/poly （DL-lactide） Composite rods. The results showed that this material has favorable intensity and no conspicuous inflammatory reaction. Those all indicated the material which has good intensity and biocompatibility refers to fixing the fractured ofcancellated bone.
