[Robotically assisted placement of a pubic ramus screw and an SI-S1 screw].

Abstract

Objective of surgery: The aim of this operation is to stabilize the anterior pelvic ring fractures on both sides and the sacral fracture on the right using robotically assisted screw osteosynthesis and to restore the mobility of the patient.

Indications: The indications arise from the patient's very severe pain, resulting immobility under conservative treatment measures and a fragility fracture of the pelvis grade II (FFP II).

Contraindications: Typical contraindications for this type of operation are the same as for conventional techniques (mainly infection and swelling).

Surgical technique: Performed in the 3D navigation hybrid operating theatre Robotic Suite with the following components: navigation unit "Curve Navigation System", movable robotic 3D cone beam computed tomography (CBCT) "Loop‑X", robotic arm "Cirq Arm System" and wall monitor "BUZZ" (Brainlab, Munich, Germany). The individual surgical steps are explained in the video online (English).

Follow-up treatment: Full weight bearing, pain medication according to the World Health Organization (WHO) stage scheme, physiotherapy after the first postoperative day.

Evidence: Navigated and robotically assisted techniques are mainly used on the spine. These techniques are also increasingly being used on the pelvis, whereby very high levels of accuracy can also be achieved.
