摘　　要：多孔Ta金属是近二十年发展起来的一种具有良好生物相容性、优异的综合力学特性的骨植入材料,具备弹性模量与骨组织相匹配、高摩擦系数提高植入体植入初期稳定性、诱导新生骨组织长入提高植入体长期稳定性等方面优势,在临床上获得广泛应用。本文从多孔Ta金属作为骨植入材料的应用背景、优势、制备方法、生物学性能以及临床应用情况等方面,阐述了多孔Ta金属作为骨植入材料的研究现状及最新动态,并对其发展前景进行了展望。Porous tantalum（PT） is an orthopedics implant material that has been developed rapidly in recent decades. PT exhibits excellent biocompatibility, outstanding comprehensive mechanical properties, initial stability originated from their high friction factor and long term stability from their good osteoinduction, which make it widely applied in clinical practice. In this review, state of the arts and recent development in the field of porous tantalum used as orthopedics implant material have been summarized and commented, which consist of introduction of its background, advantages, preparation approaches, biological performance and application status on clinic. The prospects are also described.
