摘要: Abstract Porous tantalum has become an attractive biomaterial in several orthopedic applications due to excellent biocompatibility and properties. This transition metal high volumetric porosity (75%–80%), coefficient of friction, low modulus elasticity (3 MPa) comparable cancellous bone or subchondral bone. The similar appearance is safe use vivo as evidenced by the surgery. Currently been used clinical including hip knee arthoplasty, spine fusion, osteonecrosis, cranioplasty, foot ankle surgery, tumor reconstructive ability form a self-passivating surface oxide layer which leads formation bone-like apatite coating affords fibrous in-growth properties allowing for rapid substantial soft tissue attachment. chapter discusses porous tantalum.
