“…Therefore, intraoperative visualization with conventional uoroscopy remains the current standard in most hospitals. Apart from uoroscopy, computed tomography, uoroscopic computed tomography, and computer-assisted techniques have been performed [22][23][24][25]. Some authors propose digital three-dimensional navigation printing to minimalize complications arising from sacroiliac screw misplacement [26].…”

The standard starting point for the percutaneous sacroiliac screw insertion defined by Matta and Saucedo was initially determined for surgeries performed in a prone position. Still, the technique has also been used in surgeries performed in a supine position. Therefore, the cadaveric study aimed to determine the best entry point for the percutaneous insertion of sacroiliac screws depending on the patient's positioning for surgery. K-wires were percutaneously inserted into the sacral body of eight human cadavers. In addition to the standard sacroiliac screw entry point, points located 1 cm and 2 cm cranially from along the line, prolonging the femoral axis, were studied. The K-wires were inserted into the studied entry points on the right side in a supine position and on the left side of the same cadaver in a prone position. The placement of the K-wires was assessed using radiographic imaging and cadaver dissection. The analysis revealed that all three studied entry points enabled the correct placement of orthopedic implants for surgery in the prone position. In turn, for surgery performed in the supine position, the best entry point was located 2 cm cranially from the standard entry point, along the line prolonging the femoral axis.

Arthrodesis of the sacroiliac joint (SI) usually requires a large surgical exposure using the lateral approach. Computer-assisted surgery based on intraoperative 3D fluoroscopy imaging can reduce the approach to stab incisions. The clinical example shows the insertion of two screws and a cylindrical bone graft to achieve an arthrodesis of the SI joint. The intraoperatively navigated placement of implants and bone graft was performed only by stab incisions.
