Abstract
Vertebral implants sized to be inserted into a patient and positioned in an interspinous space. The implants may include a body and a pair of wings that extend outward beyond a first side of the body. The implants are sized and configured for the body to be positioned in the interspinous space with the wings on opposing lateral sides of one of the spinous processes. The wings may be adjusted to various spaced-apart distances to be positioned on the opposing sides of the spinous process. The implants may further be selectively adjustable between a collapsed orientation and a deployed orientation. The collapsed orientation includes one or both wings aligned with the main body to reduce an overall size of the implant to facilitate insertion into a patient. The extended orientation includes the wings extending outward from the first side of the body and along the lateral sides of the spinous process.
