Similarly, the highest inflation-adjusted amount awarded ($2,302,472) for pseudarthrosis was attributed to a medially breached pedicle screw during an L5S1 fusion that was determined to have caused the failed union and subsequent need for revision surgery. The jury found the defendants liable and allocated 75 percent of the fault to Dr. Friedlander and 25 percent to Dr. Bradley. A retrospective review of charts, x-rays (XRs) and computed tomography (CT) scans was performed. 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).

Bookshelf 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. We attribute the 24.1% disc space narrowing in the instrumented segments mainly to the severe injury of the disc and communication of the end plate in burst fractures, which could accelerate the disc degeneration and narrowing. J Neurosurg Spine. Lehmann TR, LaRocca HS: Repeat lumbar surgery: A review of patients with failure from previous lumbar surgery treated with spinal canal exploration and lumbar spine fusion. In addition, seven (6.3%) dural tears occurred during the decompression and none occurred during instrumentation. However, the misplacement of pedicle screws can lead to disastrous complications. 2. Zucherman J, Hsu K, Picetti III G, et al: Clinical efficacy of spinal instrumentation in lumbar degenerative disc disease. 2002;27(22):24252430. 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. Defensive medicine in U.S. spine neurosurgery. INCLUDE WHEN CITING DOI: 10.3171/2020.8.FOCUS20600. They both had motor deficits from which 1 patient recovered completely. Epstein NE. A large number of studies have reported that in conventional thoracolumbar surgery, compared with traditional freehand screw placement, the accuracy of intraoperative pedicle screw placement has been improved with O-arm intraoperative navigation technology.

In 2 patients, misplacement of pedicle screws was recognized intraoperatively and all implants were removed. 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. Pedicle screw placement accuracy impact and comparison between grading However, the medicolegal impact of misplaced screws on spine surgery has not been directly reported in the literature. 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. Dr. Karikari is a consultant for NuVasive, Globus, Johnson & Johnson, and DePuy and receives a spine fellowship fund from NuVasive. 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.

Comparison of pedicle screw placement accuracy between two types of Roy-Camille R, Saillant G, Mazel C: Internal fixation of the lumbar spine with pedicle screw plating. 13 Whitecloud et al 35 reported 15% neurologic complications, 5% being caused by incorrect screw placement. To investigate intraoperative reinsertion of percutaneous pedicle screw (PPS) with intraoperative CT-based navigation and to evaluate the rate of deviation of PPS at postoperative radiographic examination. Therefore, when instrumentation is to be used, the benefits must outweigh the risks. Intraoperative pedicle fractures requiring further points of fixation. Both issues represent the most frequent and highest payouts in spine malpractice claims.10,14,22 While several studies have explored many of the factors related to malpractice claims in spine surgery, the medicolegal impact of misplaced pedicle and/or lateral mass screws has not been directly reported in the literature. All the incidental dural tears were repaired immediately and produced no clinical sequelae. The medicolegal impact of misplaced pedicle and lateral mass screws on To prevent general complications, it is evident that precise and careful soft tissue handling, proper irrigation, and debridement during and after surgery, decrease of operative time, and proper patient monitoring postoperatively must be done. Although the rate of the reported complications was high, the final outcome of the patients was not affected significantly. 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. This site needs JavaScript to work properly. A Cotrel-Dubousset spinal system (Medtronic Sofamor Danek, Memphis, TN) was used in all patients and the total number of screws used was 658. Federal government websites often end in .gov or .mil.

Malpractice litigation and the spine: the NHS perspective on 235 successful claims in England. 15. 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. 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). 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. Patient safety: disclosure of medical errors and risk mitigation, Neurosurgical practice liability: relative risk by procedure type. Per-patient analysis showed 23 (18.11%) of patients had all screws AP. 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. 2017;31(3):287288.

None of these complications resulted in additional surgery or in a significant increase of morbidity. In the current series, there were no cases of screw misplacement or vascular or neurologic complications caused by implant application. 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. Friedlander and Bradley will pay half of the $2.25 million. Percentage of cases per US region (center). Clin Orthop 203:717, 1986.
