Sacroiliac joint stabilization and fixation devices and related methods

A method of using an anchor device to stabilize a sacroiliac joint, comprising

• positioning an anchor device across a sacroiliac joint (SI joint) such that the device at least partially extends into a sacrum and an ilium, where the anchor device includes:
• a housing having:
• a bore;
• and
• one or more apertures;
• and
• one or more engagement members at least partially disposed in the bore of the housing, where at least one of the one or more engagement members is movable between a retracted position and an extended position such that, when the at least one of the one or more engagement members is in the extended position, the at least one of the one or more engagement members extends through at least one of the one or more apertures;
• moving an actuator in the bore of the housing toward the one or more engagement members;
• and
• engaging the actuator with at least one of the one or more engagement members, thereby moving the at least one of the one or more engagement members from the retracted position to the extended position;
• wherein, when the actuator engages the at least one of the one or more engagement members, the engagement member is longitudinally spaced from the cortical wall of the sacrum by a distance such that the engagement member is movable to the extended position within the cancellous bone of the sacrum.
