[Frequency of neurological complications connected with transpedicular spine fixation]

To asses a frequency of neurological complications concerned with transpedicular spine fixation 1127 inserted transpedicular screws were reviewed. Penetration of pedicle was found in 5.5% of inserted screws. Radicular symptoms accompanied 0.8% of screw insertions. Complications were concerned only to medial or subpedicular penetrations. Highest number of potentially hazardous medial wall penetrations was found in lower lumbar spine. Treatment consisted of removal and repositioning of screws but with direct visualisation in cases with self tapping screws systems. The results shows that rate of neurological complications during transpedicular fixation is small and procedure is relatively safe.
