Spinal fixation procedures utilizing expandable intervertebral implants can be used to correct spinal conditions such as degenerative disc disease, spondylolisthesis, spinal deformities, or other spinal conditions through minimally invasive or invasive spinal surgery. For example, intervertebral discs can degenerate or otherwise become damaged over time. In some instances, an expandable intervertebral implant can be positioned within a space previously occupied by a disc between adjacent vertebral bodies. Such expandable intervertebral implants can help maintain a desired spacing between adjacent vertebrae and/or promote fusion between adjacent vertebrae. The use of bone graft and/or other materials within an area that includes an expandable intervertebral implant can also facilitate the fusion of adjacent vertebral bodies. Accordingly, a need exists for improved expandable intervertebral implants.
