`(57) Abstract: The present invention provides decorticating screws andin-
`sertion tools for implanting the decorticating screws. The screws anchor into
`a first and a second boneto fuse the two bones together. The screws include
`a rotatable bladed section to decorticate a joint space between the first and
`second bone. The screwsalso optionally include a cap to secure the screws
`in the bone and apply compressionto the joint to be fused. In some embod-
`iments, the decorticating screws are useful for sacroiliac (SD joint fusion.
