An improved device for filling a void created in the lamina during spinal surgery including a top layer, a bottom layer and a body portion. The body portion is attached to the top layer and the bottom layer and includes a compliant mesh portion. The compliant mesh portion includes a bone material with bone morphogenetic protein (BMP) growth factor entrained thereon. The body portion is adapted to be conformable to a void left in a vertebral space after a surgeon has performed a laminectomy or hemi-laminectomy procedure. The flexible top layer has a periphery larger than that of the bottom layer such that the body portion has a section that is oblique or perpendicular to another section of the body portion or the top layer to define a flange. A method of using the device is also disclosed.
