Position locator for orthopaedic surgery has emitter fixed to bone and three dimensional locator to determine movements

摘要

The position locator for orthopaedic surgery has an emitter (3) fixed to the bone (1) and a locator with a plate (5) fixed on the bone to provide a geometric control reference (B) with respect to the emitter. The control reference provides three dimensional location of the possible displacements of the emitter with respect to the bone. Claims include a position locating method using the apparatus
