摘要

Objective of the surgery

The aim of this operation is to stabilise a T-type acetabular fracture against secondary dislocation and to restore the patientʼs preoperative functionality.

Indications

An 88-year-old patient with severe pain and immobility due to a T-type acetabular fracture (Letournel & Judet: associated fracture; AO: 62B2).

Contraindications

General surgical contraindications.

Surgical technique

This surgery was performed in a 3D-Navigation Hybrid Operating Room, the Robotic Suite (Brainlab, Munich, Germany). The setup includes a navigation unit (Curve Navigation System) a movable robotic 3D cone beam computed tomography unit (Loop-X), a robotic arm (Cirq Arm System), 3D mixed reality glasses (for planning), and a wall monitor (Buzz).

A step-by-step video is available online.

Follow-up

Immediate full weight-bearing, active and passive joint mobilisation through physiotherapy on the first postoperative day, pain medication as required.

Evidence

Navigated surgeries of the pelvis (ring and acetabulum) have become standard practice, while robotic assistance is increasingly used, demonstrating very good outcomes and promising accuracy rates.
