20130184834 | HEAD COMPONENT OF AN ORTHOPAEDIC JOINT PROSTHESIS - A kit for use in a procedure for implantation of an orthopaedic joint prosthesis includes a head component of an orthopaedic joint prosthesis, which comprises a body part having a convex bearing surface, and a reverse face at which the head component can be connected to a mating component of the joint prosthesis, in which the head component has a chamfer surface extending around at least part of its periphery where the bearing and reverse faces come together, and a plurality of markings on the chamfer surface. The kit includes a trial head component which comprises a body part having a convex trial bearing surface and a reverse face, in which the trial head component has a plurality of markings on the trial bearing surface at or towards the interface between it and the reverse face. The transverse dimensions of the head component are approximately the same as the transverse dimensions of the trial head component, and in which the location of the markings on the chamfer surface around the periphery of the head component corresponds to the location of the markings on the trial bearing surface of the trial head component around its periphery. | 07-18-2013 |
20100280517 | INSTRUMENT FOR REMOVING BONE TISSUE - An instrument for removing tissue from a bone to create a cavity which is approximately circular in outline in which tissue within a predetermined region within the circular outline is left relatively undisturbed. The instrument includes a rotational drive unit which oscillates through an angle α. A cutting head can be connected to the drive unit to cause the head to rotate. | 11-04-2010 |
20100191339 | DETERMINING THE OFFSET OF THE HEAD PART OF AN ORTHOPAEDIC JOINT PROSTHESIS STEM COMPONENT - A method of determining the offset of the head part of an orthopaedic joint prosthesis stem component, relative to the neck of the stem part on which the head part can be fitted, involves obtaining a first and second images of the patient's joint on a non-coincident first and second planes. Template parts are fitted to the first and second images of the bone, which have markings on them which can be placed relative to the head part and the stem part respectively of the patient's bone, and scales for measuring first and second displacements which are the distances between the axis of the head part and the axis of the neck of the patient's bone measured in the first and second planes. | 07-29-2010 |
