Paragraph Number

2

Bone implants and bone fixation procedures and implants have been used to secure two bones or bone parts or to fix one bone relative to other bones. For example in spinal fixation intervertebral implants can be used to secure, or fixate, two or more vertebrae through minimally invasive or invasive spinal surgery. Conventional implant assemblies can include screws that engage bone and secure the implant to the bone. However, over time the bone screws can become loose, or threads of screws can strip from the bone. This stripping and loosing can cause the screw to back out of a screw hole or rotate and loosen with the screw hole. Consequently, blocks or locks can be used to retain the screw within a screw opening of an implant. Unfortunately, existing blocks or locks do not adequately retain screws within an implant. Accordingly, a need exists for improved implant assemblies.
