[Modularity of prostheses].
Modularity allows a large choice of implants, like the use of cementless acetabular cups inducing bone ingrowth. The length and direction of the neck may also be adapted to be new joint. Risks of modularity are: implant dissociation, restriction of joint mobility, and especially augmentation of metal debris as a potential source of polyethylene wear. It is then critical to play attention to implant design, material choice and planning of the arthroplasty.
