摘要：
A pre-coated body implant (101), such as, for example, a hip prosthesis, in which that portion (1) of the implant that attaches to or is inserted into a skeletal member of the body has a pre-coating (2) of a material (e.g., an acrylic material) covering all or most of said portion and bonded there to. Incidence of loosening of the implanted prosthesis may be reduced due to the fact that a controlled me chanical bonding may be accomplished prior to surgery, shifting emphasis to the cement/cement and cement/bone interfaces during surgery. Since these are chemical bonds, there is less chance of loosening due to movements during surgery.
