The invention discloses an improved wedging cage within the sacroiliac (SI) joint and fixation screw(s). The wedging cage is adapted to be positioned between the sacrum and the lilac bone (e.g., the sacroiliac joint), and the wedging cage is effective to receive one or more fixation or axial screws to fasten the wedging cage and secure the wedging cage to the adjacent pelvic bones to provide a combination effect of fusion and/or fixation. Accordingly, the improved fixation screw assemblies promote flexibility and adaptability due to the adjustable head being movable to a locked and unlocked position relative to the screw body when implanted onto a substrate.

Fixation screw and method

Disclosed is a sacro-iliac join fusion system including a block or wedging cage positioned between the sacrum and iliac bone, wherein the block or wedging cage can fit around one or more fixation or axial screws to fasten the block or wedging cage and secure the block or wedging cage to the adjacent pelvic bones to promote fusion and fixation.
