Cement-augmented pedicle screw insertion assisted by spinal robotic systems for widespread spinal metastases.

Widespread spinal metastases can obscure bone landmarks and severely hinder surgical safety during pedicle screw insertion. Robot-assisted spinal surgery has demonstrated an excellent safety profile for pedicle screw insertion. Moreover, spinal surgery robotic systems can facilitate pedicle screw insertion with high-accuracy. We present a patient who had breast cancer with widespread spinal metastases, pathological vertebral fracture, and spinal cord compression with a challenge of intraoperative image recognition. To overcome this problem, she received surgical decompression and stabilization through the insertion of cement-augmented pedicle screws with the assistance of a spinal robotic system. At the 1-year follow-up, no implant loosening was observed, and the patient exhibited notable physical improvements, demonstrating that cement-augmented pedicle screw insertion with the assistance of spinal robotic systems is an effective method for treating widespread spinal metastases.
