Nyquist had requested the defendants offer, which in retrospect was perhaps a poor decision in light of the Kane County jurys verdict. Statistical analysis: Sankey. Despite commonly used, questions remain about their safety especially for the thoracic spine and in deformity where difficulty in positioning can lead to pedicle breach and adjacent structures injury. 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. 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%).

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. Zucherman J, Hsu K, Picetti III G, et al: Clinical efficacy of spinal instrumentation in lumbar degenerative disc disease. 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). In situ spine arthrodesis permits load sharing by the vertebral bodies, preventing fatigue failure of the implant. These numbers are in line with the current literature. Zdeblick TA: A prospective randomized study of lumbar fusion: Preliminary results. Likewise, cases are uploaded on a voluntary basis by state and federal judges and courts, which may lead to selection bias.

Risk factor analysis showed smaller Cobb angles increased likelihood of all screws being AP. Jury Verdict for Doctor for Screw Allegedly Misplaced During Lumbar Pedicle screw insertions are commonly used for posterior fixation to treat various spine disorders. 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.
