Abstract
A method for registering one or more surfaces associated with a bone for implant revision procedures includes a digitizer used to digitize surface points on remaining cement, bone surfaces, or both. The bone is adapted to hold a primary implant and from which the primary implant was removed. The position of the one or more surfaces associated with bone is registered by computing at least one of: a generic set of one or more planes using the surface points or a best match between a known implant geometry and the surface points. A computer-assisted surgical system is also provided to execute the method.
