Using MRI during surgery enables neurosurgeons to operate with remarkable precision and remove as much of the brain tumor as possible. It also reduces the risks that might result from a second operation. Surgeries with intraoperative MRI are also likely to reduce tumor . Neurosurgery of the spine covers the cervical, thoracic and lumbar spine. Some indications for spine surgery include spinal cord compression resulting from trauma, arthritis of the spinal discs, or spondylosis. In cervical cord compression, patients may have difficulty with gait, balance issues, and/or numbness and tingling in the hands or feet.

However, it is difficult to place distractors in the C2-C3 level. The normal height of the area should be reconstructed. However, care should be taken not to over distract. A complete discectomy will allow good visualization of the spinal canal and enhance fusion. The risk of C5 palsies occurring following anterior, posterior, or circumferential spine surgery varies from 0% to 30%.[] Although there are multiple theories as to the etiology of these injuries, cord migration with resultant traction injury to the C5 nerve roots, particularly following surgery at the C4-C5 level.

Intraoperative imaging with opaque instruments marking the specific boney landmarks will be done and compared with the preoperative imaging as part of the correct site verification procedure. Final verification is the comparison of the pre- and intraoperative imaging by the surgeon or other physician performing the procedure. Accurately localizing a spine level in the thoracic spine is often not easily achieved with the existing imaging modalities available in the operating room. The coordination of the preoperative imaging pathology with intraoperative imaging is even more difficult in patients with challenging anatomy.

RESULTS. So far the published articles emphasize on “intraoperative imaging after exposure and marking of a fixed anatomic structure” to prevent wrong level spine surgery,[1,4] but there are situations even this measure would not be illustrates two thoracic spine surgeries which posed difficulty in determining the correct levels during the by:   Using palpable and visible anatomic landmarks alone to identify the desired vertebral level during spine surgery has been shown to be unreliable; therefore, intraoperative radiography is a critical step in identifying the correct surgical level [4–6].

However, interpreting thoracic spine imaging can be especially challenging because nearby. Intraoperative neurophysiological monitoring (IONM) or intraoperative neuromonitoring is the use of electrophysiological methods such as electroencephalography (EEG), electromyography (EMG), and evoked potentials to monitor the functional integrity of certain neural structures (e.g., nerves, spinal cord and parts of the brain) during purpose of IONM is to reduce the risk to the.

Intraoperative findings of L5–S1 interspace and S1 lamina show features that may help in SLL during surgery. INTRODUCTION Spinal-level localization (SLL) is the most important and the first step.

Muscle MEPs for spinal cord surgery are preferably recorded from thenar and hypothenar as well as tibialis anterior and abductor hallucis muscles, respectively. The relevant parameter during spinal cord surgery is the presence and absence of MEPs.

Increase in stimulus thresholds required to obtain a response plays an additional practical role. These researchers determined that there is a high level of evidence that multi-modal (SSEP and MEP) IOM is sensitive and specific for detecting intra-operative neurologic injury during spine surgery.

There is a low level of evidence that IOM reduces the rate of new or worsened peri-operative neurologic deficits (a grade of "low" means that. Intraoperative neurophysiological monitoring is indicated in select spine surgeries when there is risk for additional spinal cord injury.

Intraoperative monitoring has not been shown to be of clinical benefit for routine lumbar or cervical nerve root decompression (AANEM ), or during routine lumbar or cervical laminectomy or fusion (AANEM.

a different location. For spinal procedures, in addition to preoperative skin marking of the general spinal region, special intraoperative imaging techniques may be used for locating and marking the exact vertebral level. Site marking must occur before the procedure is performed and with the patient awake and involved (if possible).

Consideration of intraoperative imaging verification for location of the correct level for spinal surgery is part of the North American Spine Society Clinical Care Checklist for Safety to Prevent Wrong-Site Surgery (see “Identified Best Practices Principles for Preventing Wrong-Site Surgery”).

This imaging should be compared with routine preoperative studies to determine the correct site for spine surgery. Key Points. Wrong site and wrong level surgery may be preventable.

Reviews in Spinal Surgery highlights the most important developments and controversies in spinal surgery as well as those that will shape spine care in the years to come.

Foremost experts in the field of neurosurgical and orthopedic spinal surgery have teamed to produce papers that blend current knowledge as well as “balanced” points of. the wrong side of the spine or the wrong level, but there are unique issues related to spinal localization that can be challenging for even the most experienced clinicians.
