SQ Pelvis - The process

Step 1: CT scan images of the pelvic ring injury

• CT or MRI examination modality supported.
• 2D images of pelvic injury serve as input.

Step 2: SQ Pelvis 3D model of patient based on CT modality

• 3D model reconstructed from the medical scans.
• Ready to be used by the surgeon in SQ Pelvis.

Step 3: 3D model of pelvis with coloured dislocated fragments

• SQ Pelvis consists of two closely integrated sets of tools:
• the 3D viewing tools and
• the pelvic and acetabular surgery simulation tools.
• Representing the actual patient's injury.

Step 4: 3D model of pelvis with reduced and fixed fragments

• The SQ Pelvis surgery simulation tool allows surgeons to perform the complete surgery in the virtual environment:
• individual bone fragments can be reduced to the appropriate locations by means of translation and rotation tools for optimal reconstruction of acetabulum and pelvis.
• the fragments are stabilized by virtual screws and fixation plates.
• This allows the choice of the optimal operative approach.

Step 5: Simulation of C-arm picture of the patient

• Simulation of C-arm 2D x-ray imaging is available from all views.
• By comparing virtual and actual intra-operative X-ray images, the surgeon gains a quick insight into operative procedure scenario.
• Decreased C-arm radiation during real surgery.

Step 6: Actual postoperative X-ray picture of the patient

• Using 3D viewing features of SQ Pelvis, the fractures of all patient's injuries were analysed.
• During the actual operative procedures, all the steps from the virtual planning successfully carried out.

Step 7: Online reports

Online reports are created in SQ Pelvis, including all relevant operation of the simulated surgery:

• Reduction plan
• Planned plates and screws
• Detailed design plan of plates
• Screw definition
