Abstract:
1. A sacro-iliac implant adapted to immobilize opposing naturally separated surfaces of a sacro-iliac (SI) joint, the implant comprising: a body defining a longitudinal axis and extending from a first portion having an outer surface configured for fixation with a sacrum of the SI joint to a second portion having an outer surface being spaced apart and non-continuous with the outer surface of the first portion, the body defining an axial cavity disposed in communication with spaced apart transverse openings each extending through the body; and a sleeve disposed about the body and configured for implantation within at least an ilium of the SI joint, the sleeve extending from a first portion having a substantially even inner surface configured for axial slidable movement relative to the body to a second portion having an inner surface and a flange disposed to engage an outer non-articular surface of the ilium, the sleeve defines transverse openings, the inner surface of the second portion of the sleeve being engageable with the outer surface of the second portion of the body to cause axial translation of the body relative to the sleeve in a configuration such that naturally separated articular surfaces of the sacrum and ilium are drawn into fixation to immobilize the SI joint, wherein the body is axially translatable relative to the sleeve between a first configuration in which the transverse openings of the body are spaced apart from the transverse openings of the sleeve and a second configuration in which at least one of the transverse openings of the body is aligned with at least one of the transverse openings of the sleeve.
