Abstract
Tools for positioning an implant into the sacroiliac joint. A directional cannula includes a main body having a bore that receives the implant. A cut-out, allowing access to the joint, is formed in a leading end of the main body. A pair of parallel prongs extend from the leading end of the main body in transversely spaced apart relation to one another. A drill guide has a main body of rectangular transverse cross-section and a cylindrical head formed integrally with the main body. A transverse width-reducing step is formed in the main body near its distal end. First and second bores are formed in the cylindrical head and in the main body. Both bores are eccentric relative to the drill guide longitudinal axis of symmetry. The drill guide is rotated 180° after first and second drilling operations, prior to third and fourth drilling operations.
