Excessive hemorrhage occurred in two patients (1.8%) with coagulation disorders. 15. Spine 16(8 Suppl):S455458, 1991. All case demographics are summarized in Table 1. Pedicle screw insertions are commonly used for posterior fixation to treat various spine disorders. In addition, the median time to judgment is substantial, particularly for defendant verdicts, spanning over 4.5 years from the time of surgery. Several studies reveal that fusion rates increase when rigid internal fixation is used, 14,20,21,33,38 and that by using pedicle screws and plates or rods for stabilization, spinal arthrodesis can be limited to the disease segments. Methods. Litigation resulted in average payouts of $1,204,422 $753,832 between 1995 and 2019, when adjusted for inflation. 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. 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. 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. Despite this problem, the clinical result was excellent. The last two patients had a T12L1 fracture-dislocation and a L4L5 spondylolytic spondylolisthesis at the site of plug dislodgments. 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. Bydon M, Xu R, Amin AG, et al. 2. 13. A review of medicolegal malpractice suits involving cervical spine: what can we learn or change? EOS System Courtesy of EOS imaging.

Junctional problems were recorded as pathologic changes of the adjacent motion segments, just above and below the instrumented and fused segments. Methods: Acquisition of data: Sankey. 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.

Both of these patients complained of thigh pain but refused any additional surgery. It is an effective procedure in that it provides an almost immediate stabilization of the spine [ 2-5 ]. However, 5-10% of those misplaced screws are cause for concern." "To rectify this, we must have access to imaging devices during the procedure. J Bone Joint Surg 73A:11791184, 1991. 1 Although this technique has advantages over open instrumentation, it also presents new challenges and specific complications. 15. Spine (Phila Pa 1976).

Pedicle screw insertions are commonly used for posterior fixation to treat various spine disorders. Steffee AD, Brantigan JW: The variable screw placement spinal fixation system: Report of a prospective study of 250 patients enrolled in Food and Drug Administration clinical trials. Previous biomechanical and clinical studies defining junctional segment problems are lacking and consist mainly of case reports. In the current series, there were no cases of screw misplacement or vascular or neurologic complications caused by implant application. Seven hundred sixty-three screws were inserted in 138 patients. This retrospective analysis of 68 closed medicolegal cases related to misplaced screws in spine surgery showed that neurosurgeons and orthopedic spine surgeons were equally named as the defendant (n = 32 and 31, respectively), and cases were most commonly due to misplaced lumbar pedicle screws (n = 41, 60.3%).

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. 10. States were then grouped by US region and case year by 5-year intervals. 29.

Notwithstanding these concessions, the MDU argued that misplacement of pedicle screw tracts was common in surgery of this kind, even in experienced and competent hands. Cases involving wrong-level or -side surgery, implant malfunction, or other misplaced spinal instrumentation (e.g., interbody cases, rods, surgical instruments, etc.) Several limitations should be carefully considered when interpreting our results. 2021 Jul 1;41(Suppl 1):S80-S86.

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. 36. Overall reported screw misplacement is low, but it does not reflect the potential impact on patient morbidity. Fortunately, most of the complications were minor and transient. Spine 16(8 Suppl):S422427, 1991. The defense pointed to the lack of evidence that the screw had ever come into contact with the L5 nerve root. Under this theory of liability, the plaintiff needed to not only establish that she had experienced foot drop, a fact that no one was disputing, but that it was caused by the defendants negligence. Pedicle screw placement is a common procedure. Schlegel JD, Smith JA, Schleusener RN: Lumbar motion segment pathology adjacent to thoracolumbar, lumbar, and lumbosacral fusions. The rod is held in place by "pedicle screws," which the surgeon must insert into the pedicles. Lorenz M, Zindrick M, Schwaegler P, et al: A comparison of single level fusion with and without hardware. Rather, the defense demonstrated that although the misplaced screw had in fact irritated the L4 nerve root for the six days before it was removed, the related symptoms resolved with the screws removal. Data is temporarily unavailable. 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. Critically revising the article: all authors. Med Econ. Sub-analysis of adolescent idiopathic scoliotic patients showed no curve or patient characteristic that correlated with IMP or SAR. Complications were classified as general, hardware-related, problems associated with the instrumented segments, junctional level problems, and problems related with balance (Table 2). 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.
