Retrograde posterior column acetabular screw: robotically assisted and CT-guided minimally invasive procedure.

Area of Science:

• Orthopedic Surgery
• Medical Technology
• Robotics in Medicine

Background:

• T-type acetabular fractures present complex challenges in orthopedic surgery.
• Restoring patient functionality and preventing secondary dislocation are critical treatment goals.

Purpose of the Study:

• To stabilize a T-type acetabular fracture using advanced navigation and robotic technology.
• To restore preoperative functionality in an 88-year-old patient with this fracture type.

Main Methods:

• Surgery performed in a 3D-Navigation Hybrid Operating Room featuring robotic assistance (Brainlab Curve Navigation System, Loop-X, Cirq Arm System).
• Utilized 3D cone beam CT, robotic arm, and mixed reality glasses for surgical planning and execution.
• Navigated pelvic surgeries are becoming standard, with robotic assistance showing promising accuracy.

Main Results:

• Immediate full weight-bearing was permitted post-surgery.
• Active and passive joint mobilization commenced on the first postoperative day.
• Pain management was provided as needed.

Conclusions:

• Robotic assistance and 3D navigation offer a viable approach for complex acetabular fractures.
• The technique facilitates early patient mobilization and functional recovery.
• This technology demonstrates potential for improved outcomes in pelvic surgeries.
