Percutaneous sacroiliac screw fixation with a 3D robot-assisted image-guided navigation system : Technical solutions.

ABSTRACT:

Objective

Presentation and description of percutaneous sacroiliac (SI) screw fixation with the use of a 3D robot-assisted image-guided navigation system and the clinical outcome of this technique.

Indications

Pelvic fractures involving the posterior pelvis.

Contraindications

Patients not suited for surgery.

Surgical technique

Planning the screws on the diagnostic computer tomogram (CT). Matching with a low-dose CT in the operating room. Lateral incision. Verify the guidewire position with the personalized inlet and outlet views. After correct positioning, place a cannulated screw over the guidewire. For fragility fractures, augmentation is recommended. Finish the surgery with a final 3D scan to confirm correct placement of the screws and cement.
