Abstract: Methods and apparatus for integrating an electromagnetic navigation system and a tool and aligning the tool with a target are presented, including a sensor tool, a tool, a field generator, a display, and a computer. The sensor tool attaches to a target component in a unique position relative to target features. The field generator is fixed relative to the tool except in rotation about a tool axis. The display is adjustably mounted to the tool and automatically adjusts image parameters. Target registration and error compensation methods are provided. The system detects magnetic field and signal disturbances that may lead to inaccurate navigation, filters navigation data, and adjusts filtering parameters based on detected conditions. Apparatus for proximally locking anIM nail such that a clear passage through the cannulation of the nail is maintained are provided.

Abstract: A computer assisted surgical navigation system and method is disclosed for registering the position of prosthetic hip joint components. Elements are applied to the pelvis and femur, generating a three-dimensional array. These two arrays combine to derive a reference point representing the native joint. A tracking device with a pre-determined shape and dimensions that precisely articulate with an acetabular cup component generates a third three-dimensional array. The device has a further shape and dimensions that independently articulate precisely with a neck portion of a femoral component, which represents a prosthetic joint center that is independently registered in the system. The tracking device concurrently registers the three dimensional positions of the femoral and acetabular prosthetic components, along with the prosthetic joint center and the native joint center, respectively enabling alterations in three dimensional location of the leg length and offset prior to reduction of the prosthetic joint.
