Abstract
An implant is provided which facilitates enhanced structural stability across a joint to be immobilized. The sacroiliac implant is an elongate structure having two cylindrical sections of differing diameters. The implant further has like-handed, but dissimilar pitched threaded sections at the proximal and distal ends thereof to produce compressive forces across the joint. A hollow core traverses the length of the implant. A plurality of apertures or openings are formed through the implant transversely to the longitudinal axis and communicate with the hollow core. Bone graft or a BMP-soaked carrier fill the hollow core. The openings or apertures provide a conductive path of healing for bony ingrowth. The proximal end of the implant provides for engagement with a tool to drive the implant.
