Claim 0:
1. A method for assisting a surgeon fit a prosthesis between at least two bones of a patient for hip, knee or shoulder arthroplasty, according to a determined orthopedic surgical protocol comprising at least the following steps, which as such have been excluded from the method of assisting the fitting of said prosthesis:
intervention to allow access to the bones concerned,
surgical intervention and preparation of each bone that is to receive a prosthesis according to said determined orthopedic surgical protocol,
checking the position of the bones concerned,
placement of each determined prosthesis on each of the at least two bones, the method comprising a sequence of the following steps:
affixing at least one 3D marker on each of the at least two bones of at least two limbs of the patient, each 3D marker being a cube with each face being identified by a QR code,
virtually determining and recording a 3D position of each 3D marker,
processing, by a computer, of recorded natural parameters: virtual calculated points, axes and planes,
checking the preparation of each of the at least two bones with the 3D marker attached to the bones, by continuously overlaying each point, straight line and real virtual plane recorded on the bone of the patient with corresponding points of the prosthesis,
calculating final implant parameters in relation to the recorded natural parameters,
displaying the recorded and calculated virtual parameters directly on a transparent screen so as to be overlaid on each limb and each prosthesis and provide an augmented realty display in which the virtual parameters are virtually projected on each limb and each prosthesis,
the transparent screen mounted on a pair of glasses to be worn by said surgeon.
