Objective:
Pedicle screw-based posterior instrumentation of the spine.
Indications:
Instability of the spine due to trauma, infection, degenerative spinal disease or tumor.
Contraindications:
None.
Surgical Technique:
Robot-assisted navigated pedicle screw placement.
Postoperative Management:
Early functional mobilization starting on the first postoperative day.
Results:
A study by Lee et al. analyzed the clinical application of the system Mazor X Stealth Edition (Medtronic Navigation, Louisville, CO, USA; Medtronic Spine, Memphis, TN, USA) in 186 cases with a total of 1445 pedicle screws [1]. Correct screw positioning was achieved in 1432 pedicle screws (99.1%); six pedicle screws (0.4%) were revised intraoperatively. The mean duration of pedicle screw placement was 6.1 ± 2.3 min. Pojskić et al. published a case series regarding the application of the system Cirq (Brainlab, Munich, Germany) in 13 cases with a total number of 70 pedicle screws implanted [2]. Intraoperative imaging showed screw positioning according to the Gertzbein Robbins classification (GR) category A in 65 screws (92.9%) and GR B in one screw (1.4%). Screw positioning GR D with intraoperative revision was reported in two screws (2.9%). Mean duration of pedicle screw placement was 08:27 ± 06:54 min.
