    摘要: A guide and method of using the guide for positioning within a patient between vertebral members for contouring each of the members. The guide comprises a first section and a second section. A first edge is positioned along an edge of the first section, and a second edge is positioned along an edge of the second section. One or more elongated rods extend through the sections. One or both of the sections are movable along the rods to adjust a spacing between the first edge and the second edge. When positioned within the patient, the first edge is aligned along a first vertebral member and the second edge is aligned along a second vertebral manner. A manner of locking the sections is included for preventing the sections from moving relative to each other once the first and second edges are aligned within the patient.

    摘要: Spinal spacers for fusion of a motion segment. A spinal spacer includes a body, which may be formed of a bone composition. The body includes a first end, an opposite second end, a superior face defining a superior vertebral engaging surface and an inferior face defining an inferior vertebral engaging surface. At least one of the vertebral engaging surfaces defines a set of migration resistance grooves. Each of the grooves includes a first face defining an angle of no more than about 90 degrees relative to the engaging surface and a second opposing sloped face.

    摘要: According to the invention, there is provided a trial implant and method of using same. The implant comprises a modular bracket defining a structure having an internal surface adapted to be seated on the distal aspect of a resected femur bone and an external surface with a shape resembling the normal distal condyle of the femur. The bracket has a elongated central opening appointed to expose the resected bone of the femur, including a pair of tracks for guiding a tool along a predetermined path for controlled shaping of a patellar groove in the bone exposed through the opening. An end mill guide cooperates with the bracket to receive another tool to form a deep recess for accommodating a posterior-stabilizing housing. After the patellar track is formed, the external surface of the bracket articulates with a proximal aspect of the tibia during interoperative trial reduction of the knee joint. Removal of the bracket from the resected bone is unnecessary following the shaping steps prior to performing the trial reduction.

    摘要翻译: 根据本发明,提供了一种试验植入物及其使用方法。 植入物包括限定了具有内表面的结构的模块化支架,该内表面适于坐在被切除的股骨的远侧,外表面具有类似于股骨的正常远端髁的形状。 支架具有细长的中央开口,被设置为暴露股骨的切除的骨头,包括一对轨道,用于沿着预定路径引导工具,以用于通过开口暴露的骨头中的髌骨槽的受控成形。 端铣刀引导件与支架配合以接收另一工具以形成用于容纳后稳定壳体的深凹槽。 在形成髌骨轨迹之后,在膝关节的术中试验期间,支架的外表面与胫骨的近侧方面相关联。 在执行试用减少之前,在成形步骤之后,不需要从被切除的骨中去除支架。
