A useful intraoperative technique for transiliac-transsacral screws: a point-to-point coaxial guide apparatus

摘要

The two handles are disassembled and combined (a, b). The coaxial corridor formed at the distal end can pass two cannulas (c). Insert the guide wires over the cannulas (d). As shown at the pelvis model, the two cannulas perform a point-to-point coaxial relationship by the guide apparatus and navigate the guidewire into the corridor of the screw (e, f)
