摘要： An adjustable trial prosthesis or prosthetic component provides a surgeon with the capability of efficiently and accurately examining a joint's functioning without having to remove a trial prosthesis insert and replace it with another sterilized insert. The adjustable trial has a first surface that approximates the top surface of the corresponding permanent prosthesis and a second surface that engages a bone. A distance adjustment mechanism can alter the distance between the first and second surfaces. The distance adjustment mechanism can include a screw oriented generally between the two surfaces or other distance adjustment mechanisms such as a fluid filled bladder. The adjustable trial can include force transducers to provide information on forces within the joint. To assist a surgeon with the alignment of portions of the musculo-skeletal system, a line of strong light is provided. The light source can be a laser or other suitable light source which is combined with appropriate optics. A balancing apparatus can be used to assess relative tensions on peri-articular soft tissue structures. The balance has a support that is adapted for rigid attachment directly or indirectly to a bone.

摘要： An acetabular cup prosthesis designed to customize the fit and stability of an acetabular cup in deficient acetabulae without excessive reaming of good bone surrounding the deficiency. The acetabular cup prosthesis generally comprises a cup-shaped body portion, an extension, and a liner. The extension is preferably produced at selected angles, which are appropriate to various acetabular defects, and is designed to connect to the cup-shaped body portion. The body portion and extension are secured to the bone and the liner is inserted within the body portion. Those surfaces of the body portion and extension contacting the surface of the bone are preferably porous surfaces that may have also been coated with a coating to enhance bone growth.
