Spine 16(8 Suppl):S455458, 1991. Previous biomechanical and clinical studies defining junctional segment problems are lacking and consist mainly of case reports. NCI CPTC Antibody Characterization Program. Spine (Phila Pa 1976). Hardware problems were those related to the physical change of metal and screw position. Once the spine is exposed, the appropriate levels of fixation are confirmed with the image intensifier. Spine 17:349355, 1992. JAMA. concluded that the robot-assisted technique was significantly more accurate than the traditional freehand technique.39 Despite the learning curve and initial cost of obtaining technologies such as 3D fluoroscopic devices, intraoperative CT, or robotic navigational systems, the routine use of these technologies for intraoperative imaging confirmation and potential revision of misplaced screws may help spine surgeons avoid inadvertent iatrogenic morbidity for their patients and potential litigation. Pedicle screw placement is a common procedure. From the *Department of Orthopaedic Surgery, University of Crete Medical School, Heraklion, Greece; and the **First Department of Orthopaedics, University of Athens Medical School, Athens, Greece. The .gov means its official. Hecht N, Kamphuis M, Czabanka M, et al. J Neurosurg Spine. Please do not include any confidential or sensitive information in a contact form, text message, or voicemail. In the current study, no incidence of bent and broken screws or tulip screw plug dislodgement necessitated additional treatment, and all the patients achieved solid fusion despite the failure of instrumentation. A total of 247 screws (9.07%) were BMP, 52 (1.91%) were IMP, and 29 (1.06%) were considered SAR. Todd NV. 8,24,25,32. Per-patient analysis showed 23 (18.11%) of patients had all screws AP. Another possible cause was the high lateral torques to the entire frame that occurred during tightening of the tulip screw. It has a great developing technique that is used for fixation and fusion in spine surgery. 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. Although the rate of the reported medical complications was high (36.5%), these did not significantly affect the final clinical outcome of the current patients. Clin Orthop 284:8090, 1992. Malpractice litigation following spine surgery. 9. Nyquist had requested the defendants offer, which in retrospect was perhaps a poor decision in light of the Kane County jurys verdict. A TLIF is a surgical procedure that attempts to fuse vertebrae in order to stabilize the patient's spine. Despite these failures, solid spinal arthrodesis was obtained in all patients. 16,24,28 Simultaneously, the evolution of the surgical techniques has led to increased procedural safety. N Engl J Med. Moreover, several cases stated that the surgeon used only the anteroposterior or the lateral view, but not both, and the plaintiffs counsel used this information in support of their claim. These risks can be minimized by the judicious use of instrumentation by experienced surgeons for specific indications as supported by the literature.
