摘要： Implant inserters and related methods are disclosed herein, e.g., for delivering a fusion cage or other implant to a spinal disc space and for rotating or articulating the implant within the disc space. An exemplary instrument can include an inner member having opposed jaws for grasping the implant and holding the implant during insertion. The inner member can be slidably received within an outer member such that relative axial translation of the inner and outer members is effective to open or close the jaws. The jaws and/or the distal end of the outer member can have a low-profile geometry, which can advantageously facilitate certain surgical procedures. For example, the low-profile geometry can allow for a more medial approach to an intervertebral disc space in which the implant is to be inserted.

摘要： A hybrid spinal implant device, and method of making the same are disclosed. The spinal implant device comprises two facing endplates, each having at least one anchoring wall or pin element, and a plastic spacer anchored to and located between the two endplates. The endplates may be manufactured from titanium. The plastic spacer may be manufactured from a radiolucent, and bio-compatible polymer-based material including polyetheretherketone (“PEEK”), polyetherketone, polyetherketoneketone, and/or fiber reinforced plastic. The endplates made of titanium allow for enhanced bone growth, while the plastic/PEEK spacer element allows for improved load absorption and distribution. The spinal implant device, using titanium endplates and a PEEK spacer, provides excellent radiolucency thereby eliminating the need for X-ray markers either intra- or post-operation. The manufacturing method for the hybrid spinal implant device uses injection molding to insert or back injection mold the spacer between the two endplates.

摘要： The present disclosure relates to a spinal implant or spacer that addresses the variation in anatomy of vertebrae along the spine by having inferior and superior surface angle and convexity variations that are adapted to address the differences in lordosis and endplate surface convexity of the spine. The difference between the convexity of the superior and inferior surface of the spacer increases as the lordotic angle of the spacer increases. The spacers described herein thus provide overall improved fit into vertebral disc space and in some embodiments are even used in the absence of fusion for a prolonged period. The vertebral spacers described herein in some embodiments are used with supplemental internal fixation systems, such as an anchor plate. The interior of the spacer has channels and undercuts to increase graft volume and retention, support bony ingrowth, and bony stability for better secondary and tertiary stabilization.

摘要翻译： 公开了一种混合脊柱植入装置及其制造方法。 脊柱植入装置包括两个相对的端板，每个端板具有至少一个锚定壁或销元件，以及锚固并位于两个端板之间的塑料隔板。 端板可以由钛制成。 塑料隔板可以由射线可透过材料和与生物相容的聚合物基材料制成，包括聚醚醚酮（“PEEK”），聚醚酮，聚醚酮酮和/或纤维增强塑料。 由钛制成的端板允许增强骨生长，而塑料/ PEEK间隔元件允许改善负载吸收和分布。 使用钛端板和PEEK间隔器的脊柱植入装置提供优异的放射性，从而消除在手术后或手术后的X射线标记的需要。 混合脊柱植入装置的制造方法使用注射成型来在两个端板之间插入或后注射模制间隔件。
