General complications were considered those developing during and after surgery that were not directly related to instrumentation. Many technological advances have been made over the past several decades in an effort to improve the accuracy of screw placement in spine surgery.3436 For example, 3D fluoroscopybased image guidance has been shown to decrease the pedicle breach rate in several studies compared to the rate with 2D fluoroscopic guidance or the freehand technique, particularly in deformity and revision surgeries.21,34,36,37 CT guidance or intraoperative confirmation has also been shown to further improve the accuracy of pedicle screw placement,3638 with reported accuracy rates of 89%100% reported in the literature, depending on the authors breach criteria.35 However, it is important to note that the use of this technology is often accompanied by a lower threshold for intraoperative screw revision, sometimes leading to higher rates of replaced screws.33 Arguably, these improved trajectories may avoid iatrogenic neurological deficits due to prolonged nerve root compression or even improve the stability of the construct;34,37 however, prospective studies of long-term outcomes and rates of revision surgery remain sparse in the literature.

Roy-Camille R, Saillant G, Mazel C: Internal fixation of the lumbar spine with pedicle screw plating. 3,4,9,29,34 In addition, developments in surgical technique and implant design have decreased operative risk and implant-related complications.

Pedicle screw insertions are commonly used for posterior fixation to treat various spine disorders, deformities, and trauma. The rod is held in place by "pedicle screws," which the surgeon must insert into the pedicles. 1. Level of evidence: A total of 47 (69.1%) cases resulted in a decision for the defendant and 21 (30.9%) for the plaintiff. Before Svider PF, Husain Q, Kovalerchik O, et al. 26 They support that after a lengthy symptom-free period, segments next to a fused segment can break down and the segment next to the adjacent segment is almost as likely to break down as the adjacent segment. A total of 2396 screws were placed accurately (87.96%). The pedicle screws judged as misplacement. a Medial minor perforation An official website of the United States government. Neurosurgery.

Misplaced pedicle and lateral mass screws result in a considerable risk of malpractice litigation against spine surgeons. In situ spine arthrodesis permits load sharing by the vertebral bodies, preventing fatigue failure of the implant.
