Abstract: BACKGROUND:Porous tantalum with high porosity, low elastic modulus, high friction coefficient has stable biological characters and good biocompatibility, which is considered as an ideal implant material in orthopedic surgery. OBJECTIVE:To review the application situation of porous tantalum used in artificial joints, spine, bone necrosis, defects of bone and so on. METHODS:A computer-based search of PubMed, Wanfang, and VIP databases was performed for relevant articles published from 1990 to 2014 using the keywords of “porous tantalum, biological character, orthopedic applications” in English and Chinese. RESULTS AND CONCLUSION:Porous tantalum is a kind of good orthopedic implant material, with high porosity, low elastic modulus, high friction coefficient, and good compatibility. Porous tantalum is mostly used in the preparation of integrated acetabular cup, total hip arthroplasty acetabular cup, acetabular reinforcing pad, porous tantalum metal rod, tibial plateau prosthesis, patelar prosthesis and tibial plateau prosthesis, which has achieved good clinical effects.
