Abstract:
Implants sized to be inserted into an intervertebral space between first and second vertebral members, and related methods. The spinal implant may have a body extending along a longitudinal axis with opposing first and second longitudinal ends. An end cap is mounted to the body at one of the ends and disposed longitudinally outboard of the corresponding end. The end cap comprises a first portion, a second portion, and an annular elastic element, such as an O-ring. The first and second portions are disposed circumferentially around the longitudinal axis. The annular elastic member circumferentially surrounds the first portion, the second portion, and the longitudinal axis. The annular elastic member applies a compressive force that urges the first and second portions together in a direction transverse to the longitudinal axis. The end cap may be flat or angled. Other implants and related methods are disclosed.
