This occurred on only one side and the correction achieved by the instrumentation was maintained. A review of medicolegal malpractice suits involving cervical spine: what can we learn or change? A misplacement rate of more than 20 % (129 misplaced screws out of 608) seems to be unacceptable compared to only 4.5 % misplacements when using CT-navigation leading to the conclusion that pedicle screw instrumentation in the middle and upper thoracic area should be carried out with the help of navigation only. Seven hundred sixty-three screws were inserted in 138 patients. 2. Placement of thoracolumbar pedicle screws using three-dimensional image guidance: experience in a large patient cohort. The most frequent primary injury listed for a lawsuit was nerve root injury, present in 81.0% (n = 17) and 74.5% (n = 35) of plaintiff- and defendant-awarded cases, respectively (p = 0.7). A rod is used to hold the vertebra together to allow fusion to occur. A TLIF is a surgical procedure that attempts to fuse vertebrae in order to stabilize the patient's spine.

Examples of both laterally and medially misplaced lumbar pedicle screws are provided in Fig. The remaining two patients had asymptomatic junctional problems develop after two- and three-segment fusions, at the third and fourth postoperative year, respectively. Start; O firmie; Usugi; Serwis; Realizacje i porady; Kontakt 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. However, following the spinal fusion, Nyquist began to experience foot drop in her right foot. First, this is a retrospective analysis of cases obtained from the web-based Westlaw Edge legal research database. Phone/Fax: 30-2810-318361; E-mail: [emailprotected]. 2019;19(7):12211231. The defense pointed to the lack of evidence that the screw had ever come into contact with the L5 nerve root. When grouped by US region, most cases occurred in the Northeast (n = 25, 36.8%), followed by the West (n = 15, 22.1%; Fig. One of the patients had a late wound infection develop that was treated by radical debridement and removal of instrumentation. Lumbar Spine Surgery. 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. Five patients had uneventful early postoperative course. 28.

Three-dimensional printing versus freehand surgical techniques in the surgical management of adolescent idiopathic spinal deformity. Spine 14:472476, 1989. This patient recovered completely in 6 weeks. Abstract BACKGROUND CONTEXT Surgeons have increasingly adopted robotic-assisted lumbar spinal fusion due to indications that robotic-assisted surgery can reduce pedicle screw misplacement. There were nine instrumentation failures at the thoracolumbar area (seven patients), lumbar area (one patient), and lumbosacral area (one patient). 2 One of the first obstacles regarding . 2. Cotrel Y, Dubousset J, Guillaumat M: New universal instrumentation in spinal surgery. Long spine fixation was necessary for patients with tuberculous spondylitis and metastatic disease. 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. Quraishi NA, Hammett TC, Todd DB, et al. You are talking one of the most complicated area of the law. However, the impact of robotic-assisted spinal fusion on patient outcomes is less clear. 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. Spine J. One hundred four of the 112 patients had a posterior procedure.
Reoperation for Misplaced Pedicle Screws: A Multicenter Retrospec 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. 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. There were 74 men and 38 women, with a mean age of 47 years (range, 1872 years). 2018;27(9):23392347. 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. Neurosurgical experience with malpractice litigation: an analysis of closed claims against neurosurgeons in New York State, 1999 through 2003. Edwards CC: Spinal screw fixation of the lumbar and sacral spine: Early results treating the first 50 cases. Pedicle screw insertions are commonly used for posterior fixation to treat various spine disorders, deformities, and trauma.

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. 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. Spine (Phila Pa 1976). These numbers are in line with the current literature. The majority of screws were misplaced in the lumbar spine for both plaintiff- and defendant-awarded cases (66.7% vs 57.4%, respectively, p = 0.564; Table 1).

Forty-seven intraoperative and medical complications were observed in 41 patients (36.6%). The average followup was 35 months (range, 1851 months). The rate of misplaced pedicle screws ranges from 1.1% to 28.8%, 10 although neurologic injury from misdirected pedicle screws has been reported to occur in 0% to 12% of patients. Health Aff (Millwood). Sethi MK, Obremskey WT, Natividad H, et al. Pedicle screw fixation is an effective but demanding method to treat various spinal disorders and is associated with a significant complication rate. And while the offending screw was removed the next day, Nyquist continued to experience right foot drop, along with lower back pain and sciatica, i.e.
The medicolegal impact of misplaced pedicle and lateral mass screws on Surg Neurol Int. Through the use of expert witness testimony, Mr. da Costa was able to prove to the jury that by misplacing the pedicle screw during the surgery, and failing to timely diagnose and correct the malpositioned screw, Defendants deviated from accepted standards of care. South Med J 62:17, 1969. In this example, the surgeon replaced the misplaced screw prior to leaving the operating room, which arguably played a significant role in the jury ruling in favor of the defendant (surgeon). Your message has been successfully sent to your colleague. Hecht N, Kamphuis M, Czabanka M, et al. Error in trends, major medical complications, and charges associated with surgery for lumbar spinal stenosis in older adults. Harrington PR, Tullos HS: Reduction of severe spondylolisthesis in children. While the majority of claims are found to lack merit, resulting in a verdict in favor of the defendant or case dismissal,7,1316 at least 37% are considered valid.26 Regardless, payouts to plaintiffs are often substantial, averaging in the hundreds of thousands to millions of dollars in both the US and Europe.10,11,14,17,20 Communication of errors and expectations, thorough documentation, and selection of appropriate patients and surgical indications have been shown to reduce the likelihood of a successful malpractice claim.13,16,27,28 In addition, attempts at tort reform in some states have helped limit the financial burden of medical malpractice payouts through methods such as capitation.16,20,22,26 However, efforts to limit malpractice claims in the first place are greatly needed. Although pedicle screw fixation opened a new horizon of spinal surgery by providing rigid fixation of the spine, it is a technically demanding procedure with potential complications including medical complications, hardware and technical problems, and long-term changes of junctional motion segments. 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. Sarwahi V, Ayan S, Amaral T, Wendolowski S, Gecelter R, Lo Y, Thornhill B. Spine Deform. were excluded from analysis. 2017;31(3):287288. Dr. K. D.

Achieving proper lumbar lordosis, evaluating any preexisting scoliosis, and intraoperative assessment with AP radiographs could prevent balance problems. Segal J. Spine surgery has been disproportionately impacted by medical liability and malpractice litigation, with the majority of claims and payouts related to procedural error.
and 17.1% of the patients included had at least one screw misplaced. Problems of balance were coronal (scoliosis greater than 5 or trunk shift greater than 5 mm) as seen on the AP radiograph taken with the patient standing or sagittal (failure to obtain or maintain lumbar lordosis). Accuracy of pedicle screw placement and clinical outcomes of robot-assisted technique versus conventional freehand technique in spine surgery from nine randomized controlled trials: a meta-analysis. Incidence and costs of defensive medicine among orthopedic surgeons in the United States: a national survey study. 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. Quinnell RC, Stockdale HR: Some experimental observations of the influence of a single lumbar floating fusion on the remaining lumbar spine. 14. Unfortunately, the plaintiffs attorney was unable to offer an alternative theory of surgical negligence that would refute the defendants explanation. It is an effective procedure in that it provides an almost immediate stabilization of the spine [ 2-5 ].
20 Tips to Avoid and Handle Problems in the Placement - ScienceDirect Breakage of a divergent screw of a Chopin block at the lumbosacral area was seen 3 months after surgery. In five patients with thoracolumbar injuries, who were the first treated in the current series, and in four patients with fractures in the lower lumbar spine, two-segment fixation was used. J Neurosurg Spine.

Reviewed submitted version of manuscript: all authors. With pedicle shapes and sizes varying wildly in the scoliotic spine, misplacement of a screwas well as and under- or oversizingare real possibilities in spine surgery. 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). Each side was judged separately. This study revealed an overall accuracy rate of 95.2% of mainly percutaneously inserted pedicle screws according to the classification of Zdichavsky et al. Copyright © 2023 Becker's Healthcare. Problems in the instrumented segments were considered those occurring from narrowing of the disc space greater than 3 mm, pseudarthrosis, and loss of reduction. Nyquist had requested the defendants offer, which in retrospect was perhaps a poor decision in light of the Kane County jurys verdict. Median screw misplacement rate was 10% in group A and 13% in group B. It should be used by experienced and qualified surgeons who are aware of the pitfalls associated with its use. At the trials close, the plaintiffs attorney had asked the jury to return a $5.3 million verdict and had made a prior demand to settle the medical malpractice lawsuit for $1 million.

Using chi square analysis, statistically significant correlation was seen between disc space narrowing and loss of postoperative correction (p < 0.01). J Spine Surg. Administrative/technical/material support: Mehta, Wang, KD Than. JAMA. Of note, while only 38.2% (n = 26) of cases in our study mentioned the use of intraoperative radiographic confirmation, only one of these cases reported that the misplaced screw had been caught prior to leaving the operating room, which had resulted in an inadvertent dural tear and L5 nerve root injury.
Pedicle screw replacement in spinal surgery - The MDU Saillant G: Etude anatomique des pedicules vertebraux: Application chirurgicale. Cases involving wrong-level or -side surgery, implant malfunction, or other misplaced spinal instrumentation (e.g., interbody cases, rods, surgical instruments, etc.) Therefore, when instrumentation is to be used, the benefits must outweigh the risks. Patient safety: disclosure of medical errors and risk mitigation. Use of the Airo mobile intraoperative CT system versus the O-arm for transpedicular screw fixation in the thoracic and lumbar spine: a retrospective cohort study of 263 patients. Several limitations should be carefully considered when interpreting our results. Risk factor analysis showed smaller Cobb angles increased likelihood of all screws being AP.

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. Eur Spine J. Balch CM, Oreskovich MR, Dyrbye LN, et al. EOS System Courtesy of EOS imaging. The highly litigious environment within healthcare has resulted in a majority of physicians practicing defensive medicine,15 often leading to burnout6,7 and an exorbitant ethical and financial burden on medical and surgical care.7,8 In 2008, medical liability accounted for $55.6 billion, representing 2.4% of the United States (US) healthcare expenditures that year,5,7,9,10 and the pervasive practice of defensive medicine may cost up to $210 billion annually in the US.5 A similar trend has been observed in Europe.11, Neurosurgery is the specialty most frequently affected by lawsuits and the fear of litigation, both in the US and abroad,12 with spine surgery at the forefront.11,1317 As a result, spine surgeons are nearly three times more likely than nonspine surgeons to practice defensive medicine, defined as the avoidance of high-risk procedures and the provision of unnecessary services and assessments beyond what is clinically necessary in an effort to avoid litagation.5 The average time to judgment in a case is approximately 5.1, 5.0, and 3.4 years for defendant verdicts, plaintiff rulings, and settlements, respectively.7,15 As a result, physicians spend an average of 11% of their careers dealing with one or more open malpractice claims.18 Neurosurgeons are especially impacted, spending an average of 27.2% of their careers in an open lawsuit.10. 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. 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. As part of the surgery, Dr. Taras Masnyk inserted four metal screws into the plaintiff's spine. Potential complications may include increased pain, infection, or mechanical . Katonis PG, Kontakis GM, Loupasis GA, et al: Treatment of unstable thoracolumbar and lumbar spine injuries using Cotrel-Dubousset instrumentation.

2012;7(6):e39237. Misplaced pedicle and lateral mass screws result in a considerable risk of malpractice litigation against spine surgeons. Finally, considering the problems of balance, it seems that failure to properly evaluate any preexisting scoliosis was a main cause of this important complication. and transmitted securely. Pedicle screw instrumentation is widely used for the stabilization of the subaxial cervical, thoracic, and lumbar spine. Defensive medicine in U.S. spine neurosurgery. Junctional problems were recorded as pathologic changes of the adjacent motion segments, just above and below the instrumented and fused segments.
The pedicle screws judged as misplacement. a Medial minor perforation It is easier to confuse a jury than convince a judge: the crisis in medical malpractice. Arthrodesis was questionable in eight asymptomatic patients (7.1%). Accuracy of C2 pedicle screw placement using the anatomic freehand technique. A Cotrel-Dubousset spinal system (Medtronic Sofamor Danek, Memphis, TN) was used in all patients and the total number of screws used was 658. Although the rationale for using pedicle screw fixation is fairly clear, controversy continues regarding the application of pedicle instrumentation for spine arthrodesis, especially on the degenerative lumbar spine. 12. Spine 13:952953, 1988. reported that 69.3% of neurosurgeons who responded to their survey saw every patient as a potential lawsuit.1. J Neurosurg Spine. Copyright 2023 Becker's Healthcare. 31.
