Subjects were 10,754 patients (73,777 pedicle screws) who underwent PSF at 11 hospitals over 15 years. The screws were needed to stabilize the spine and fix the fused vertebrae in place. It has a great developing technique that is used for fixation and fusion in spine surgery. Pedicle screw replacement in spinal surgery - The MDU Malpractice litigation and the spine: the NHS perspective on 235 successful claims in England. 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. 2 One of the first obstacles regarding . 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. 2020;45(2):E111E119.

Conception and design: Sankey, KD Than. Clin Orthop 284:8090, 1992. 144 Many technological advances have been made over the past several decades in an effort to improve the accuracy of screw placement in spine surgery.3436 For example, 3D fluoroscopybased image guidance has been shown to decrease the pedicle breach rate in several studies compared to the rate with 2D fluoroscopic guidance or the freehand technique, particularly in deformity and revision surgeries.21,34,36,37 CT guidance or intraoperative confirmation has also been shown to further improve the accuracy of pedicle screw placement,3638 with reported accuracy rates of 89%100% reported in the literature, depending on the authors breach criteria.35 However, it is important to note that the use of this technology is often accompanied by a lower threshold for intraoperative screw revision, sometimes leading to higher rates of replaced screws.33 Arguably, these improved trajectories may avoid iatrogenic neurological deficits due to prolonged nerve root compression or even improve the stability of the construct;34,37 however, prospective studies of long-term outcomes and rates of revision surgery remain sparse in the literature. A total of 47 (69.1%) cases resulted in a decision for the defendant and 21 (30.9%) for the plaintiff. 15. Examples of both laterally and medially misplaced lumbar pedicle screws are provided in Fig. $2 Million Spinal Surgery Case Against Neurosurgeon and Hospital Likewise, research shows that breaches still occur when these tools are used,33,40 and some studies did not find a difference in pedicle breach rates compared to those with traditional fluoroscopic and freehand techniques.33 Ultimately, misplaced instrumentation is a risk of any spinal fusion surgery, and a thorough discussion of these risks, as well as the alternative management options, is essential to maintain high-quality patient care and to avoid litigation.

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). (PDF) Accuracy of pedicle screw placement in the lumbosacral spine Arthrodesis was questionable in eight asymptomatic patients (7.1%). At the lumbosacral area, breakage of a divergent screw of a Chopin block occurred on only one side with no loss of correction. 8600 Rockville Pike leg pain. Grubb SA, Lipscomb HJ: Results of lumbosacral fusion for degenerative disc disease with and without instrumentation: Two- to five-year follow-up. The pedicle screw system is widely used in spine surgery, and it provides rigid fixation and leads to successful subsequent deformity correction and bony fusion. The remaining eight patients, including two patients with spinal trauma, five patients with infection, and one patient with a tumor, had anterior and posterior procedures.

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). In addition, studies have shown that over 85% of malpractice claims are either dismissed or settled out of court,14 which likely results in a high degree of underreporting. This retrospective study analyzes the complications and the problems developed during and after pedicle screw fixation in patients with spinal disorders and trauma. Introduction. Spine 18:11601172, 1993. First, this is a retrospective analysis of cases obtained from the web-based Westlaw Edge legal research database. Nyquist followed a medical malpractice lawsuit against Dr. Masnyk for his surgical error, alleging that the surgeon had improperly positioned the right L4 pedicel screw which had resulted in a nerve root injury and Nyquists subsequent foot drop. [] The accuracy for free-hand screw placement technique varies from 69% to 94%. A retrospective review of closed medicolegal cases with verdicts or settlements between 1995 and 2019 was performed using the Westlaw Edge legal research database (Thomson Reuters).7,14,16,23,24 A search of closed federal and state malpractice claims within the Verdicts and Settlements section consisted of the following: spine and surgery and pedicle and screw and fusion and (misplaced or misguided or mispositioned) and surgeon. Inclusion criteria consisted of malpractice claims against surgeons for complications related to misplaced pedicle and/or lateral mass screws. Fager CA. Spine (Phila Pa 1976). The link was not copied. Ultimately, no significant differences were seen in inflation-adjusted award information between plaintiff and defendant (Table 3). The rate of reoperation for screw misplacement per screw was 0.17%. 2011;365(7):629636. government site. Spine 13:696706, 1988. Dr. K. D. Than is a consultant for Bioventus and receives honoraria from DJO and LifeNet Health. Nyquist had requested the defendants offer, which in retrospect was perhaps a poor decision in light of the Kane County jurys verdict. The defense pointed to the lack of evidence that the screw had ever come into contact with the L5 nerve root. Morphometric analysis of the proximal thoracic pedicles in Lenke II and IV adolescent idiopathic scoliosis: an evaluation of the feasibility for pedicle screw insertion. Pedicle screw construct have become one of the most practiced procedure in spinal surgery. Defensive medicine: a culprit in spiking healthcare costs. Drs. Katonis, Pavlos MD*; Christoforakis, Joseph MD*; Aligizakis, Agisilaos C. MD*; Papadopoulos, Charalampos MD*; Sapkas, George MD, DSc**; Hadjipavlou, Alexander MD*. Clin Orthop 203:126134, 1986. The standard imaging technique for pedicle screw insertion is two-dimensional images obtained from C-arm-type X-ray fluoroscopy. 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. Data is temporarily unavailable. When adjusted for inflation, these values increased to $1,330,201 $882,023 versus $970,832 $381,619, respectively (p = 0.32; Fig. 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. (PDF) Lumbosacral pedicle screw placement using a fluoroscopic pedicle A total of 247 screws (9.07%) were BMP, 52 (1.91%) were IMP, and 29 (1.06%) were considered SAR. There were nine instrumentation failures at the thoracolumbar area (seven patients), lumbar area (one patient), and lumbosacral area (one patient). J Neurosurg Spine.
