Quinnell RC, Stockdale HR: Some experimental observations of the influence of a single lumbar floating fusion on the remaining lumbar spine. Nyquist followed a medical malpractice lawsuit against Dr. Masnyk for his surgical error, alleging that the surgeon had improperly positioned the right L4 pedicel screw which had resulted in a nerve root injury and Nyquists subsequent foot drop. It is indicated that screws medially misplaced at a distance greater than 2-mm, especially 4 mm, may be a cause of negative effects on the neural structure and should be removed during the early phase of the postoperative period, even among patients without postoperative neurological abnormalities.

Pedicle screw fixation is commonly used in spinal instrumentation surgeries to connect rods to vertebrae in order to correct spine alignment, stabilize vertebrae, and reach an arthrodesis. 3. Pitfall: Unstable injuries. 3,4,9,29,34 In addition, developments in surgical technique and implant design have decreased operative risk and implant-related complications. Screw misplacement. Thankfully, most screws are just misplaced by a millimeter or two out the front or are slightly off medially, so they are not doing real damage. This step in implant evolution was inevitable, because prior phases of implant development did not control each plane of motion segment stress.

Screws penetrating the anterior cortex and abutting vascular structures, particularly aortic abutment with left-sided screws, which can lead to erosion and pseudoaneurysms. J Spine Surg. Several limitations should be carefully considered when interpreting our results. Dr. Abd-El-Barr is a consultant for Spineology. Instrumentation removal is an option for patients with successful arthrodesis, but remains controversial. Operative information including fusion level, number of levels fused, level of misplaced screw(s), single versus multiple misplaced screw(s), presence of known CSF leakage, and primary injury due to screw misplacement was also collected. The states with the most cases included California (n = 10, 14.7%), New York (n = 6, 8.8%), Pennsylvania (n = 6, 8.8%), and Illinois (n = 5, 7.3%; Table 2). In the current study, only five patients with junction problems above the instrumented area were observed with the following probable predisposing factors: an already degenerative disc, coronal imbalance, very long arthrodesis, and old age. States were then grouped by US region and case year by 5-year intervals. In order to prove medical malpractice occurred, the plaintiffs attorney needs to show not only the plaintiff experienced a poor medical outcome, but that it was directly caused by medical negligence. Plaintiff's expert was prepared to testify at trial that these complaints are characteristic of a malpositioned screw impinging upon a neural structure.

On April 6, a Union County, N.J., jury awarded a plaintiff $4.5 million over a botched spine surgery. concluded that the robot-assisted technique was significantly more accurate than the traditional freehand technique.39 Despite the learning curve and initial cost of obtaining technologies such as 3D fluoroscopic devices, intraoperative CT, or robotic navigational systems, the routine use of these technologies for intraoperative imaging confirmation and potential revision of misplaced screws may help spine surgeons avoid inadvertent iatrogenic morbidity for their patients and potential litigation. Gertzbein SD, Robbins SE: Accuracy of pedicular screw placement in vivo. J Bone Joint Surg 54A:11951204, 1972. Thus, we are unable to comment on whether all misplaced screws, particularly when asymptomatic, should be revised in an effort to prevent litigation.
