Abstract
Systems, methods, and devices for sacroiliac joint fusion described include an implant comprising a first body having a distal anchor and a second body having proximal anchor. The first body includes a threaded body integrally formed with the first body or threadably coupled to the first body. The distal anchor may be formed by a pair of deployable wings. The pair of deployable wings may be deployed within the cancellous bone of the sacrum and anchored against the cortical bone of the sacrum. The proximal anchor may engage with an outer surface of the ilium. The second body may be threaded along the threaded body to provide compression across the sacroiliac joint. Compressing the sacroiliac joint can reduce motion thereof to promote fusion and stabilization.
