And while the jury debated for about two hours, at the end of its deliberation it sided with the defendants and entered a not guilty verdict. The physician ordered an MRI of the lumbar spine which showed that the screws had been misplaced and were puncturing the patient's lumbar nerves. 2021 Nov;9(6):1541-1548. doi: 10.1007/s43390-021-00377-5. 2002;27(22):24252430. 16,24,28 Simultaneously, the evolution of the surgical techniques has led to increased procedural safety.

Junctional problems were recorded as pathologic changes of the adjacent motion segments, just above and below the instrumented and fused segments. Moreover, local court rulings are not included in the Westlaw Edge database; however, this is unlikely to present meaningful bias given that malpractice claims are generally filed in state courts.

This device was used with an early version of the Cotrel-Dubousset instrumentation to provide sacral fixation and it is rarely used since the more widespread use of newer spine fixation systems. Except for the patient with an infected pseudarthrosis who had a flat back syndrome (sagittal imbalance) develop, coronal imbalance was observed in five patients (4.5%), and ranged from 7.5 to 12 (Fig 3). Disc space narrowing was the most common problem after instrumented arthrodesis and was observed in 27 patients (24.1%).

What can spine surgeons do to improve patient care and avoid medical negligence suits? The pedicle screw system is widely used in spine surgery, and it provides rigid fixation and leads to successful subsequent deformity correction and bony fusion. and transmitted securely.

This study has shown that percutaneous insertion of pedicle screws in the lumbar spine is a safe and reliable technique, and despite the low misplacement rate of only 6.6%, it should be kept in mind that the surgical procedure is technically demanding and should be performed only by experienced spine surgeons. 2018;28(2):186193. Eur Spine J. The initial search using the terms above returned 3654 cases. 2011;365(7):629636.

Background The objective of this cadaveric study was to analyze the effects of iatrogenic pedicle perforations from screw misplacement on the mean pullout strength of lower thoracic and lumbar pedicle screws. This step in implant evolution was inevitable, because prior phases of implant development did not control each plane of motion segment stress.

Brodsky AE: Post-laminectomy and post-fusion stenosis of the lumbar spine. Spine 6:263267, 1981. However, we did not observe any screw breakage in patients with a degenerative lumbar spine, and the absence of broken screws in this series is because arthrodesis in almost all patients occurred in situ. In our opinion, these problems may be prevented by applying the following principles: limitation of spine arthrodesis to the pathologic levels, inclusion of already extensive changes at the level above or below the planned arthrodesis into the arthrodesis, restoration of postoperative sagittal and coronal alignment, and avoidance of impingement syndrome from the adjacent nonfused facets. Conversely, Nyquists foot drop did not resolve after the screw was removed, which begged the question of whether the foot drop was in fact caused by the misplaced screw. 2005;293(21):26092617. Over 40% of patients had screws with either some/major concern.

Pedicle Screw Malposition Expert Witness: Malposition Can Lead to West III JL, Bradford DS, Ogilvie JW: Complications of the variable screw pedicle screw fixation. 13. Pullout strength of misplaced pedicle screws in the thoracic and lumbar A Cotrel-Dubousset spinal system (Medtronic Sofamor Danek, Memphis, TN) was used in all patients and the total number of screws used was 658. A total of 2724 screws were placed in 127 patients. Judgment information associated with a defendant (surgeon) versus plaintiff (patient) ruling, trial versus settlement versus arbitration decision, award amount, and time to decision or case closure from index surgery was also recorded. Sub-analysis of adolescent idiopathic scoliotic patients showed no curve or patient characteristic that correlated with IMP or SAR. However, published reports are increasingly demonstrative of the positive effect of pedicle fixation on arthrodesis and successful outcome in the treatment of patients with these disorders. The plaintiff will recover $2.25 million because of a high-low agreement the lawyers entered after closing arguments, the New Jersey Law Journal reports. Segal J.

A TLIF is a surgical procedure that attempts to fuse vertebrae in order to stabilize the patient's spine. Instead, the defense offered up an alternative explanation for Nyquists foot drop. Pedicle screw insertion in the thoracolumbar spine. 1). Medical malpractice litigation has made a significant impact on spine surgery, with many spine surgeons avoiding complex cases or practicing other defensive medicine tactics in an effort to avoid being sued.5 Moreover, the majority of neurosurgeons spend more than 10% of their annual revenue on malpractice insurance,1,14 and the excessive financial risk of litigation is even leading some insurers to no longer offer coverage to spine surgeons.19 A 2011 study in the New England Journal of Medicine found that 19.1% of neurosurgeons are named as a defendant in a malpractice suit each year (highest of any specialty).12 Moreover, 88% of physicians in high-risk specialties, like neurosurgery, are involved in a lawsuit by age 45, increasing to a concerning 99% by 65 years of age.12 Such litigation places a substantial financial, temporal, and emotional burden on physicians in high-risk specialties, with studies showing that up to 72% of neurosurgeons1 admitted that their fear of litigation significantly influenced their practice,25 with many avoiding high-risk patients altogether.1 Similarly, Nahed et al. Defensive medicine in U.S. spine neurosurgery. Cookie Policy. Are We Underestimating the Significance of Pedicle Screw Misplacement These complications may have resulted from powerful bending movement acting on the screw at its entry point to the bone. J Bone Joint Surg 54A:11951204, 1972. In several of the studies in the spinal literature, the contention that instrumentation improves arthrodesis rates, considering that nonunion contributes to a poor outcome in spinal arthrodesis is favored. Studdert DM, Mello MM, Sage WM, et al. The medicolegal impact of misplaced pedicle and lateral mass screws on Pedicle screw insertions are commonly used for posterior fixation to treat various spine disorders. One hundred twelve consecutive patients were entered into a retrospective study of instrumented thoracolumbar, lumbar, and lumbosacral spinal arthrodesis at our institution, between September 1994 and January 1999. Summary of background data: Johnston II CE, Ashman RB, Baird AM, Allard RN: Effect of spinal construct stiffness on early fusion mass incorporation: Experimental study. In the current study, the arthrodesis rate of 89.4% compares favorably with other previously reported series in the spinal literature, most of which use radiographic means to access the status of the spinal arthrodesis. Twenty-one patients (18.8%) had thoracolumbar injuries, and loss of immediate postoperative deformity correction ranged from 1.4 to 4.5. In four of these patients, bent screws occurred at 8 to 10 months after surgery; in three patients, broken screw necks were seen 1 year after surgery and in two patients, tulip screw plug dislodgments were observed at 4 and 6 months postoperatively, respectively. 19. Cotrel Y, Dubousset J, Guillaumat M: New universal instrumentation in spinal surgery. Determining legal responsibility in otolaryngology: a review of 44 trials since 2008. All these problems were observed only just above the upper instrumentation level and all were observed in patients older than 55 years. Patient safety: disclosure of medical errors and risk mitigation, Neurosurgical practice liability: relative risk by procedure type. A CT scan was taken to try and identify the underlying neurological problem that might be causing the new symptom. 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. In the Kane County medical malpractice lawsuit of Melissa Nyquist v. Dr. Taras Masnyk and DuPage Neurosurgery, S.C., 06 L 421, the plaintiffs attorney was unable to convince the jury that the plaintiffs medical complications were caused by the defendants negligence.
