Abstract
An apparatus and method for precision bone alignment includes a plurality of markers secured to bone portions prior to an orthopaedic/surgical procedure. Light emitting LED's are provided on said markers and are sensed by an optical three-dimensional sensor which provides respective positional electric signals to a computer, the computer in turn being connected to a monitor to provide a three-dimensional display. The signals prior to the orthopaedic/surgical procedure are stored in the computer. The sensor also provides signals following the orthopaedic/surgical procedure for comparison with the signals before the procedure to insure proper alignment.
