Minimally Invasive Percutaneous Modified Iliac Screw Placement Using Intraoperative Navigation: A Technical Note

Area of Science:

• Spine surgery
• Orthopedic surgery
• Minimally invasive spinal techniques

Background:

• Spinopelvic fixation is crucial for treating complex spinal pathologies.
• Traditional methods may have limitations in achieving stable fixation.
• Modified iliac screws offer a potential alternative for enhanced stability.

Observation:

• A novel percutaneous technique for modified iliac screw placement was developed.
• The technique was applied to a patient with an L5 vertebral fracture and ankylosing spondylitis.
• Intraoperative navigation and a single stab incision were utilized for screw insertion.

Findings:

• The modified iliac screw fixation was performed safely and effectively using a percutaneous approach with intraoperative image guidance.
• The technique allowed for easy alignment of the screw head with the S1 pedicle screw without rod connectors.
• The patient experienced rapid pain relief, and radiographic follow-up confirmed successful fracture healing without hardware complications.

Implications:

• This minimally invasive technique provides a safe and efficient option for spinopelvic fixation.
• It simplifies the surgical procedure by eliminating the need for rod connectors and preventing acute angulation issues.
• The technique holds promise for improving outcomes in patients requiring complex spinal stabilization.
