SPINAL IMPLANTS AND RELATED INSTRUMENTS AND METHODS

摘要

Apparatus, methods, and systems relating to spinal implants and instruments for installing such implants. In some embodiments, a spinal implant may comprise an opening configured to receive an installation rod for installing the spinal implant within an intervertebral space of a patient. The opening may be positioned within a wall of the spinal implant, and may comprise a peripheral edge defined by the wall of the spinal implant. An installation rod may be provided that may be configured to be positioned within the opening of the spinal implant, and may comprise an engagement section configured to engage a portion of the spinal implant defining the opening at a location spaced apart from the peripheral edge such that the highest forces applied to the spinal implant in coupling the spinal implant with the installation rod during installation are not applied to the portion of the opening defined by the peripheral edge.

主权项

1. A spinal implant system, comprising:
a spinal implant comprising:
a first sidewall;a second sidewall opposite from the first sidewall;an upper surface configured for engaging a first vertebra;a lower surface configured for engaging a second vertebra adjacent to the first vertebra;a first end wall joining the first sidewall and the second sidewall at a first end of the spinal implant;a second end wall joining the first sidewall and the second sidewall at a second end of the spinal implant opposite from the first end, wherein the second end wall defines a second end wall surface; andat least one of a recess and a protrusion formed in the second end wall; andan opening positioned within the second end wall, wherein the opening comprises a threaded region, and wherein the threaded region is spaced apart from the second end wall surface; and an installation rod configured to be positioned within the opening, wherein the installation rod comprises a threaded section configured to engage the threaded region of the opening at a location spaced apart from the second end wall surface.
