　View Summary

<p>Near-real-time frameless stereotaxy registering intraoperative anatomy to a preoperative three-dimensional computer model has been developed for use with in vivo pedicle screw placement. Eight patients underwent thoracolumbar and lumbar spine stabilization surgery using this new technology, and 32 pedicle screws were placed. Three additional patients had 12 pedicle screws removed during revision surgery and they allowed the authors to estimate the accuracy of this navigational system. Accuracy was determined by comparing pedicle screw position on postoperative computed tomographs for the first eight patients and on preoperative computed tomographs for the latter three patients, with the intraoperative computer trajectory data gathered during operation. In the group of eight patients, all screws were intrapedicular. In evaluating all 11 patients, the overall accuracy was ± 2 mm, but the greatest error of 5.4 mm was noted in the sagittal plane measurement. During the development phase of this technology, time constraints prolong surgery, but this may be addressed once the tool's accuracy has been confirmed and intraoperative radiographic confirmation becomes unnecessary. In vivo real-time frameless stereotaxy for pedicle screw placement offers promise for the future. Refinements are needed to improve accuracy and address time constraints.</p>

Anterior dural laceration caused by thoracolumbar and lumbar burst fractures

Carl A. L., Matsumoto M., Whalen J. T.

Journal of Spinal Disorders 13 ( 5 ) 399 - 403 2000

ISSN  0895-0385

　View Summary

<p>A retrospective review of the records of 60 patients with thoracolumbar and lumbar burst fractures was undertaken to document the incidence and evaluate the sequelae of dural injuries found during anterior procedures. In the entire series, six (10%) patients each had a preexisting vertically oriented dural tear. All patients with anterior dural lacerations were male and had associated neurologic deficits. In all six patients, preoperative computed tomography showed an asymmetrically retropulsed bone fragment. Dural tears were repaired primarily. A postoperative cerebrospinal fluid leak developed into the chest cavity of one patient, who was treated successfully with subarachnoid drainage. In patients with anterior dural laceration, primary repair is warranted and can be performed more easily after intraoperative correction of kyphosis. Subarachnoid drainage may be effective in cases of continued postoperative anterior cerebrospinal fluid leakage before repeated operation is considered.</p>
