摘要： A system for spinal surgery includes a prosthesis comprising a plurality of bone anchors which engage an intervertebral construct for fusion or motion preservation. The fusion construct comprises a spacer optionally encircled by a jacket. The motion preservation construct may comprise an articulating disc assembly or an elastomeric disc assembly. Any of the constructs may occupy the intervertebral disc space between adjacent vertebrae after removal of an intervertebral disc. The anchors slidingly engage the construct to securely fix the prosthesis to the vertebrae. The anchors and jacket of the fusion construct provide a continuous load path across opposite sides of the prosthesis so as to resist antagonistic motions of the spine.

摘要： A knee prosthesis including a femoral implant, a tibial implant, a tibial insert and a cam post. The femoral implant is secured to a femur and has a cam feature and condyles. The tibial implant is secured to a tibia. The tibial insert comprises a medial cavity with a rotational axis. The tibial insert has articulating surfaces that match the contours of the condyles of the femoral implant. The tibial insert has a medial boss that aligns with the medial cavity allowing it to rotate about the rotational axis. A cam post is secured to the tibial implant and passes through a channel of the tibial insert providing anterior and posterior stops for the rotation of the tibial insert about the rotational axis. The cam post interacts with the femoral implant cam feature and, with the tibial insert, allows more anatomically correct rollback and femoral external rotation during knee flexion.

摘要翻译： 包括股骨植入物，胫骨植入物，胫骨插入物和凸轮柱的膝关节假体。 股骨植入物被固定到股骨上并具有凸轮特征和髁。 胫骨植入物被固定到胫骨上。 胫骨插入物包括具有旋转轴线的中间腔。 胫骨插入物具有与股骨植入物的髁的轮廓匹配的关节表面。 胫骨插入物具有与中间空间对准的中间凸起，允许其围绕旋转轴线旋转。 凸轮柱固定到胫骨植入物上并通过胫骨插入物的通道，其提供前部和后部止动件，以使胫骨插入物围绕旋转轴线旋转。 凸轮柱与股骨植入物凸轮特征相互作用，并且与胫骨插入物在膝关节屈曲期间允许更多的解剖学上正确的回滚和股骨外旋。
