摘要： In one aspect, a bone plate system is provided that includes a bone plate body having a throughbore and a bone screw. The bone plate system includes a slider slidably connected to the bone plate body to slide between a clearance position wherein the slider permits a bone screw head portion to be advanced into the throughbore and seated against the bone plate body and an interference position wherein the slider inhibits bone screw back out from the throughbore. The bone plate system includes a resilient pin and the slider has a surface configured to deflect the resilient pin as the bone screw head portion shifts the slider from the interference position toward the clearance position. The deflected resilient pin urges the slider from the clearance position toward the interference position upon the bone anchor head portion seating against the bone plate body in the throughbore.

摘要： A bone plate system is provided that includes bone plates and bone anchor assemblies for being inserted into bone plate bores to secure the bone plates to one or more bones. In one aspect, the bone plate system includes a bone anchor assembly having a locking cap and a locking fastener connected to a head portion of a bone anchor. The bone anchor assembly is driven into a bone plate bore before the locking fastener is shifted to expand the locking cap and fix the bone anchor assembly within the bore. In another aspect, the bone plate system includes a bone anchor assembly having a locking cap that deflects radially inward due to contact with the bone plate at large bone anchor assembly insertion angles. In addition, a bone anchor assembly having a preassembled condition with a locking cap resisting back out of a locking fastener.

摘要： An intervertebral implant for being implanted between adjacent vertebrae is provided. The implant includes a generally elongate implant body having a length extending between opposite longitudinal ends thereof, a superior face and an inferior face. The superior face and inferior face include cortical teeth adjacent to the implant body longitudinal ends. Additionally, the superior and inferior faces include longitudinally central teeth intermediate the cortical teeth and have bone engaging ends. The central teeth have a sharper configuration than that of the cortical teeth bone engaging ends for biting into the softer central bone material of the vertebrae. The cortical teeth are arranged in a first density per unit area and the central teeth are arranged in a second density per unit area that is less than the first density.
