In six patients (5.3%) with degenerative spine disease, the disc material had been removed. In two patients in the current series, dislodgement of the rods from tulip screws occurred, as reported originally by Edmunds et al. When adjusted for inflation, these values increased to $1,330,201 $882,023 versus $970,832 $381,619, respectively (p = 0.32; Fig. 15. Clinical Orthopaedics and Related Research, Get new journal Tables of Contents sent right to your email inbox, The Association of Bone and Joint Surgeons, Complications and Problems Related to Pedicle Screw Fixation of the Spine, Articles in Google Scholar by Pavlos Katonis, MD, Other articles in this journal by Pavlos Katonis, MD, Privacy Policy (Updated December 15, 2022). A total of 2396 screws were placed accurately (87.96%). Potential complications may include increased pain, infection, or mechanical . Privacy Policy. 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. [] The accuracy for free-hand screw placement technique varies from 69% to 94%. After the removal of duplicates, a total of 68 unique cases met our inclusion criteria and were included for analysis. Please do not include any confidential or sensitive information in a contact form, text message, or voicemail. 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. 20. Of the 112 patients, 57 patients had a lumbar degenerative disorder, (lumbar degenerative spinal canal stenosis in 23 patients, degenerative or spondylolytic spondylolisthesis in 12 patients, postlaminectomy instability or stenosis in 20 patients, and recurrent disc prolapse in two patients), 42 patients had spinal cord injury, eight patients had infection, and five patients had a spinal tumor (Table 1).

Your current browser may not support copying via this button. demonstrated that the number of hospital discharges for spinal fusion increased 2.4 times (137%) from 174,223 to 413,171 (p < 0.001) between 1998 and 2008.32 The true frequency of malpositioned pedicle and lateral mass screws is likely underestimated in spine surgery given the fact that the majority of misplaced screws, as well as the potential complications related to them, are not reported in practice and may be clinically silent. 2014;174(11):18671868. Bydon M, Xu R, Amin AG, et al. This retrospective study analyzes the complications and the problems developed during and after pedicle screw fixation in patients with spinal disorders and trauma. 2014;20(2):196203. Finally, considering the problems of balance, it seems that failure to properly evaluate any preexisting scoliosis was a main cause of this important complication. Most of these complications were minor and with the exception of two misplaced screws, did not contribute to the occurrence of neurologic impairment or severe pain.

However, the medicolegal impact of misplaced screws on spine surgery has not been directly reported in the literature. This was followed by pseudarthrosis requiring revision surgery, present in 14.3% (n = 3) and 14.9% (n = 7) of plaintiff- and defendant-awarded cases, respectively (p = 0.99). 2017;42(3):177185. Spine 19(20 Suppl):2279S2296, 1994. 2002;27(22):24252430. Another possible cause was the high lateral torques to the entire frame that occurred during tightening of the tulip screw. General complications were considered those developing during and after surgery that were not directly related to instrumentation. A total of 2724 screws were placed in 127 patients. Federal government websites often end in .gov or .mil. The link was not copied. Unilateral nonunion was seen in three patients (2.7%), associated with implant failure in one of the patients. Luque ER: Segmental spinal instrumentation of lumbar spine. The medicolegal landscape of spine surgery: how do surgeons fare? 2013;32(1):111119. 7. Pedicle screw insertions are commonly used for posterior fixation to treat various spine disorders. Edmunds I, Cummine J, Fearnside M: Prevention of dislodgement of Cotrel-Dubousset rods from tulip screws. Spine 13:952953, 1988. Pedicle screw placement is a common procedure. Three slender patients complained of soft tissue irritation and a bothersome prominence because of the screws bulky profile. 34. The suit claimed Dr. Friedlander failed to diagnose and treat the mispositioned screw in a timely manner, leading the plaintiff to develop pain in his right leg, numbness in his right calf and weakness in his right toes. Instead, the defense offered up an alternative explanation for Nyquists foot drop. 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. J Bone Joint Surg 62A:13021307, 1980. Svider PF, Kovalerchik O, Mauro AC, et al. Overall reported screw misplacement is low, but it does not reflect the potential impact on patient morbidity. The defendants explanation provided an explanation for why Nyquists foot drop did not resolve after the misplaced screw was removed and shed doubt on the plaintiffs theory of liability. On average, physicians spend nearly 11 percent of their 40-year careers with an open, unresolved malpractice claim. 2018;41(5):e615e620. Li HM, Zhang RJ, Shen CL. Achieving proper lumbar lordosis, evaluating any preexisting scoliosis, and intraoperative assessment with AP radiographs could prevent balance problems. 9. Pedicle screw placement accuracy using ultra-low radiation imaging with image enhancement versus conventional fluoroscopy in minimally invasive transforaminal lumbar interbody fusion: an internally randomized controlled trial. 2019;19(7):12211231. Image intensification and the technique recommended by Weinstein et al 32 was used for screw placement in the lumbar vertebrae, whereas Chopin blocks (Medtronic Sofamor Danek) with two screws diverging bilaterally were used for sacral fixation. 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.

As compared to cases in 19952009, those in 20102019 resulted in a significantly higher average nominal payout to plaintiffs ($776,439 $74,460 vs $1,506,000 $385,527, p = 0.028). Junctional problems were recorded as pathologic changes of the adjacent motion segments, just above and below the instrumented and fused segments. 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. PURPOSE This study aimed to compare rates of perioperative complications between robotic-assisted and conventional . Better strategies need to be devised for evaluation of screw placement, including establishment of a national database of deformity surgery, use of intra-operative image guidance, and reevaluation of postoperative low-dose CT imaging. Rajasekaran S, Bhushan M, Aiyer S, et al. West III JL, Bradford DS, Ogilvie JW: Results of spinal arthrodesis with pedicle screw-plate fixation. We avoid using sharp automated drilling, and probe fully the pedicle cavity to prevent nerve root impairment. 18. Previous biomechanical and clinical studies defining junctional segment problems are lacking and consist mainly of case reports. The average age of the patients was 47 years and the average followup was 35 months. Eur Spine J. Recently, robot-assisted pedicle screw implantation has been increasingly utilized at large-volume academic centers. 2012;7(6):e39237. The incidence of screw failure, which can occur despite solid arthrodesis, 7 in the current series was 8% and mainly involved patients with thoracolumbar injury. Dr. Friedlander did not order a CT or MRI until January 2013, when the pedicle screw was found to be in the wrong location and a failed fusion was diagnosed, according to the suit. We serve the following localities: Cook County including Arlington Heights, Barrington, Berwyn Township, Chicago, Des Plaines, Glenview, Orland Park, Palos Park, Schaumburg, and Tinley Park; DuPage County including Downers Grove, Naperville, and Bolingbrook; Kane County including Aurora, Elgin and Geneva; Lake County including Waukegan; and Will County including Joliet. 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).

Spine 8:970981, 1996. 2014;96(4):266270. Spine 17:834837, 1992. Seven hundred sixty-three screws were inserted in 138 patients. $ = US$; MW = Midwest; NE = Northeast; SE = Southeast; SW = Southwest; W = West. Problems at the junctions of the instrumented spine were seen in five patients (4.5%). 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. Materials and Methods Sixty . 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. 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). Clin Orthop 203:126134, 1986. 2017 Mar;5(2):109-116. doi: 10.1016/j.jspd.2016.10.007. PLoS One. However, the misplacement of pedicle screws can lead to disastrous complications. The largest inflation-adjusted payout awarded to the plaintiff ($3,372,185) for nerve root injury occurred in a 36-year-old male who had undergone an L4S1 posterior spinal fusion, which resulted in permanent and direct injury to right L5 and S1 nerve roots, with foot drop and radiculopathy. 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. 1. However, the highest offer had been a combined $300,000 from the two defendants. 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. Likewise, cases are uploaded on a voluntary basis by state and federal judges and courts, which may lead to selection bias. There were 74 men and 38 women, with a mean age of 47 years (range, 1872 years). Dr. Goodwin has received grants from the Burroughs Wellcome Fund, North Carolina Spine Society, and Robert Wood Johnson Harold Amos Medical Faculty Development Program and the NIH/NINDS K12 NRCDP Physician Scientist Award. 14. Spine 16(8 Suppl):S422427, 1991. 1 To be effective, the pedicle screw constructs must withstand intraoperative loading and physiological forces due to daily postoperative activities. Plaintiff-awarded cases by US region (left). However, 5-10% of those misplaced screws are cause for concern." "To rectify this, we must have access to imaging devices during the procedure. 2020;45(2):E111E119. All of these patients were asymptomatic and had satisfactory final clinical outcomes (Fig 2). Melissa Nyquist required a lumbar back fusion for a herniated disc at the L4-5 level. 39. Feb. 16, 2021 Accurate placement of pedicle screws is key to avoiding the potential complications of spinal fusion surgery and improving overall spinal fixation. 27,30 Infected pseudarthrosis developed in one patient (0.9%) with an L4S1 arthrodesis, and the instrumentation was removed 18 months later resulting in a flat back syndrome. Amount awarded to plaintiffs by US region, adjusted for inflation as of April 2020. 2009;10(1):3339. A p < 0.05 was considered statistically significant. While the majority of verdicts are found in favor of the defendant (surgeon), over 30% of cases in this study were found in favor of the plaintiff (patient), resulting in average inflation-adjusted payouts of over $1.2 million per claim over the past 25 years. One of the patients had a late wound infection develop that was treated by radical debridement and removal of instrumentation. Fishers exact test and the Mann-Whitney U-test were used for the analysis of categorical and continuous data, respectively, except when an unpaired t-test was utilized for analyses related to normalized, nominal, and inflation-adjusted award totals. Drafting the article: Sankey. The authors of the current study aimed to describe this impact in the United States, as well as to suggest a potential method for mitigating the problem. 6 Nominal and inflation-adjusted award payouts were higher for trial verdicts than for settlement/arbitration, with a nominal average of $1,140,473 $841,683 versus $788,533 $306,186 awarded to the plaintiff, respectively (p = 0.30). Study supervision: Goodwin, Karikari, Shaffrey, Abd-El-Barr, KD Than. In patients with degenerative conditions, all of the affected segments were included in the instrumentation and each vertebra was fixed with two pedicle screws. The total number of reoperations for MPS and patient clinical data were obtained from medical records at each hospital. In six of these patients with injuries at the thoracolumbar area (four patients with bent screws and two patients with broken screws), the loss of correction ranged from 3 to 4.5 without change of anatomic reduction (Fig 1). Eur Spine J. 4). There were nine instrumentation failures at the thoracolumbar area (seven patients), lumbar area (one patient), and lumbosacral area (one patient). 2. Of note, the award amount for one settlement case was undisclosed. The screws were needed to stabilize the spine and fix the fused vertebrae in place. The medical malpractice suit Ayala v. Friedlander, M.D., claimed that a March 2011 lumbar fusion surgery performed by neurosurgeon Marvin Friedlander, MD, and orthopedic spine surgeon Douglas Bradley, MD, strayed from the accepted standards of care because a pedicle screw was placed in the wrong location. laterally placed screws and the azygous vein on the right (T5-T11). 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 . Din RS, Yan SC, Cote DJ, et al. Pedicle screw insertions are commonly used for posterior fixation to treat various spine disorders, deformities, and trauma. Forty-seven intraoperative and medical complications were observed in 41 patients (36.6%). Routine CT scans were taken in all patients. I won't be at the office but I will check my voice mail. The contact form sends information by non-encrypted email, which is not secure. Inaccurate pedicle screw placement is relatively common even when placement is performed under fluoroscopic control.
