摘要： A spinal spacer 300 for engagement between vertebrae is provided which includes a body 301 formed of a bone composition. The body 301 includes a first end 311, an opposite second 315 end, a superior face 335 defining a superior vertebral engaging surface 337 and an inferior face 338 defining an inferior vertebral engaging surface 340. At least one of the vertebral engaging surfaces defines a set of migration resistance grooves 350. Each of the grooves 350 includes a first face 355 defining an angle of no more than about 90 degrees relative to the engaging surface 340 and a second opposing sloped face 360. The first and second faces 355, 360 define an arcuate pocket 370 therebetween for trapping vertebral bone to resist migration of the spacer 300. In one embodiment, the grooves 350 are arranged in series in that all of the second faces 360 slope in the same direction.

摘要： A retrofit posterior stabilizing housing is disposed in a resected receptacle in the trochlear groove of a human femur during revision surgery through the intercondylar notch of a previously implanted condylar-type femoral prosthetic component. The posterior stabilizing housing is dimensioned to pass through the notch in the existing implant and seat superiorly to the trochlear opening of the notch. The posterior stabilizing housing includes medial and lateral side walls extending from a proximal ceiling portion, and anterior and posterior end walls disposed between the side walls, defining a box-like container. An aperture is formed in each of the side walls for receiving screw-like fasteners anchored in the cancellous bone portion of the femur. A pair of anchor posts extend superiorly from the ceiling portion for fixation within the femur. The posterior stabilizing housing may either be cemented in place or the superior surface thereof textured to enhance bone ingrowth.
摘要翻译：改进的后稳定壳体通过先前植入的髁型股骨假体部件的髁间隙在修复手术期间设置在人股骨的滑车槽中的切除的容器中。后稳定壳体的尺寸设计成穿过现有植入物中的凹口并且优先于凹口的滑车开口。后稳定壳体包括从近侧顶部延伸的内侧壁和侧壁，以及设置在侧壁之间的前端壁和后端壁，形成盒状容器。在每个侧壁中形成有孔，用于接收固定在股骨的松质骨部分中的螺钉状紧固件。一对锚柱从顶部上方延伸，用于固定在股骨内。后稳定壳体可以胶合到位或其上表面纹理化以增强骨向内生长。

摘要： A surgical device for accurately positioning and cutting a patellar groove in a resected distal femur to receive a patellar track portion of a prosthesis, including a guide element adapted to fit over the distal end of a resected femur, having a central opening which exposes the central, distal an anterior aspects of the femur, each side of the opening being provided with a track, extending the length of the patella track, and, a cutting tool having a cutting surface, perferably convex, adapted to fit into the central opening for the purpose of cutting or abrading a groove into the femur as the tool is moved along the opening. The tool, which is preferably a rotary cutter provided with independently rotatable track-engaging surfaces on each side of the opening is adapted to engage and move along the track.
