Abstract: A device for providing passive, wireless, in vivo detection of post-surgical infection in a surgical implant or prosthesis is provided. The device includes at least one magnetoelastic-based sensor associated with the implant or prosthesis. At least one magnetoelastic-based sensor is a differential sensor. Also, the differential sensor comprises a reference element and a sensing element.

Abstract: A bone plate has a first frame portion with a plurality of apertures. The apertures may have central axes angled with respect to a bone contacting surface adjacent thereto at an angle of other than 90°. The plate has a second plate portion comprising a plurality of apertures therethrough and has a first end connected to the first plate portion. The plate has a third plate portion having first and second ends respectively connected to a second end of the second plate portion and to the first plate portion at a point thereon closer to a center of the first plate portion than the first end of the second plate portion to the first plate portion. The first, second and third plate portions having an arcuate shape capable of conforming to an arcuate bone surface, the bone contacting surface forming a concave portion of the arcuate shape.

Abstract: The insertion tool and pusher system of the present invention includes a bone screw having a head and a shaft. An annular washer is adapted to be mounted on the bone screw shaft. An insertion tool having a longitudinally extending shaft with an axial bore therethrough is provided for receiving the bone screw. The shaft has a first end with a washer retention surface surrounding the insertion tool cannulated shaft bore. The washer is held on the retention surface which positions the washer to receive the bone screw shaft. Pin-like spring elements are used to hold the washer in position. A plate is mounted on an outer surface at the first end of the inserter shaft, the plate having a bone contacting surface.
