Pedicle screws are used by spine surgeons as part of a fusion in which two adjacent bones in the spine are combined together as one. 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. Copyright 2023 Becker's Healthcare. 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.

Complications and Problems Related to Pedicle Screw Fixation - LWW Incidence and costs of defensive medicine among orthopedic surgeons in the United States: a national survey study. Disc space narrowing was the most common problem after instrumented arthrodesis and was observed in 27 patients (24.1%). Intraoperative and postoperative complications were recorded by the authors and the results were evaluated by an independent observer. Once the spine is exposed, the appropriate levels of fixation are confirmed with the image intensifier. Screws penetrating the anterior cortex and abutting vascular structures, particularly aortic abutment with left-sided screws, which can lead to erosion and pseudoaneurysms. Yuan HA, Garfin SR, Dickman CA, Mardjetko SM: A historical cohort study of pedicle screw fixation in thoracic, lumbar and sacral spinal fusions. 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. However, only a few complications were related to a poor clinical outcome. There were 74 men and 38 women, with a mean age of 47 years (range, 1872 years). 12. It argued that the foot drop was unavoidable and due to the surgeons need to manipulate the right L5 nerve root in order to remove Nyquists herniated disc during the spinal fusion surgery. Neurosurgical experience with malpractice litigation: an analysis of closed claims against neurosurgeons in New York State, 1999 through 2003. Privacy Policy. 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. Axial lumbar CT scans demonstrating both laterally (right) and medially (left) misplaced pedicle screws, resulting in pedicle and transverse process fractures (A) and canal compromise (A and B). The remaining two patients had asymptomatic junctional problems develop after two- and three-segment fusions, at the third and fourth postoperative year, respectively. Descriptive analysis of state and federal spine surgery malpractice litigation in the United States. Categorical and continuous data are described as frequency (percentage) and median (interquartile range), respectively, except for the use of mean standard deviation for award amounts since both nominal and inflation-adjusted award totals passed (alpha = 0.05) the DAgostino-Pearson omnibus normality test.

Rev Chir Orthop Reparatrice Appar Mot 62:151160, 1976. To reinforce spinal fixation, we have proposed a construct with segmental pedicle fixation two levels above and one level below the injured level and insertion of a screw deep into the pedicle, providing more contact area between screw head and bone and reducing the moment arm of the bending stress. Legal liability in iatrogenic orbital injury. 17,18,31,39 Edwards 6 showed that solid arthrodesis developed in 96% of patients without previous surgery, whereas 84% of patients having secondary operations experienced a similar result. Whitecloud et al 35 reported an overall 45% rate of minor and major complications, with the rate of complications increasing to 63% in patients who had previous lumbar surgery. However, despite the apparent widespread use of pedicle system fixation, few studies of problems and particularly complications have been published. 9. Intraoperative pedicle fractures requiring further points of fixation.
Pullout strength of misplaced pedicle screws in the thoracic and lumbar While reported to be one of the best legal research resources available and utilized in several previous studies,7,14,16,23,24 available court documents and clinical/operative details are highly variable and greatly limited among case files. A high-low agreement is a settlement in which a defendant agrees to pay the plaintiff a minimum recovery in exchange for the plaintiff agreeing to accept a maximum amount regardless of the trial's outcome. The accuracy rate of pedicle screw (PS) placement varies from 85% to 95% in the literature. Spine arthrodesis was evaluated with plain AP and lateral radiographs taken 1 year after surgery. 8600 Rockville Pike The cost of defensive medicine on 3 hospital medicine services. 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.

I won't be at the office but I will check my voice mail. Seven hundred sixty-three screws were inserted in 138 patients. However, the misplacement of pedicle screws can lead to disastrous complications because of the close proximity to neural tissue and the surrounding vessels, although rare, serious complications have been reported, such as dural tear, nerve-root irritation, neural injury . A total of 2724 screws were placed in 127 patients. Although the rate of the reported medical complications was high (36.5%), these did not significantly affect the final clinical outcome of the current patients. Daniels AH, Ruttiman R, Eltorai AEM, et al. Using chi square analysis, statistically significant correlation was seen between disc space narrowing and loss of postoperative correction (p < 0.01). There were no observed cases of screw misplacement outside the pedicle on routine AP and lateral radiographs.

3). A total of 69 patients (mean age, 67.416 . To prevent the development of pseudarthrosis, we think it is important for surgeons to apply the following five technical principles: the proper-sized pedicle screw has to be inserted on the first attempt; repeated manipulation in setting instruments must be avoided; anterior penetration of the screw into the sacrum and insertion of two screws in each side are advocated for fixing the lumbosacral junction; industrious and detailed decortication of the posterior elements must be developed fully; and the use of autologous bone graft is recommended. The medicolegal landscape of spine surgery: how do surgeons fare?
Thoracic Pedicle Screws - ScienceDirect Problems at the junctions of the instrumented spine were seen in five patients (4.5%). In two patients in the current series, dislodgement of the rods from tulip screws occurred, as reported originally by Edmunds et al. One common area for the potential avoidance of malpractice claims and subsequent payouts involves misplaced pedicle and/or lateral mass instrumentation. Before L3S1 spine arthrodesis was done in the first patient but the correction of scoliosis was not sufficient and coronal imbalance persisted after surgery, which accelerated the degeneration of the level just above the arthrodesis. However, the misplacement of pedicle screws can lead to disastrous complications. Although the rate of the reported complications was high, the final outcome of the patients was not affected significantly. 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. Spine 18:11601172, 1993. Orthopedics. The last two patients had a T12L1 fracture-dislocation and a L4L5 spondylolytic spondylolisthesis at the site of plug dislodgments. Don't jump in get legal help. Show more. 2013;34(6):699705. 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. Per-patient analysis showed 23 (18.11%) of patients had all screws AP. 11. 2012;7(6):e39237.

In situ spine arthrodesis permits load sharing by the vertebral bodies, preventing fatigue failure of the implant. However, this difference was no longer significant when adjusted for inflation ($1,016,000 $90,875 vs $1,630,000 $422,405, p = 0.09). EOS System Courtesy of EOS imaging. One hundred twelve patients were treated using the Cotrel-Dubousset pedicle screw fixation system for degenerative disease (57 patients), trauma (42 patients), infection (eight patients), and tumor (five patients) of the lumbar or thoracolumbar spine. 2013;123(9):20992103. 2011;213(5):657667. This demonstrates technical ability but does not represent the impact of screw misplacement on individual patients. The intent is to provide relief from pain and nerve damage. Am J Otolaryngol. Additional survey data have shown that 50% of physicians exhibit at least a temporary loss of self-esteem after a malpractice claim, and at least 25% experience depression.22 As stated above, the average neurosurgeon spends 27.2% of his or her entire career in an open malpractice claim,10 and each case can take an average of 5.1, 5.0, and 3.4 years for defendant verdicts, plaintiff rulings, and settlements, respectively.7,15 Likewise, neurosurgeons have a higher risk than practitioners in other specialties of being named in multiple malpractice suits given the particularly high-risk nature of the specialty.10 Even when found in favor of the defendant (surgeon), each case ultimately takes a substantial emotional and financial toll on the physician(s) involved.
