Posterior cervical decompressive laminectomy and lateral mass screw fixation.
OBJECTIVE To review the results and complications of cervical decompressive laminectomy and lateral mass screw fixation. METHODS This retrospective study was carried out between October 2006 and January 2010 at King Abdullah University Hospital, Irbid, Jordan. Over 40 months, 405 lateral mass screws were placed in 50 patients aged 22-65 years (17 females, and 33 males) for variable cervical p...
متن کاملPosterior Lateral Mass Screw Fixation: Anatomic and Radiographic Considerations
During the last 10 years, posterior plating utilizing lateral mass screw fixation has become more popular for treating instability of the lower cervical spine. Injury to the spinal nerves associated with insertion of lateral mass screws is the main complication of this procedure. The purpose of this article is to briefly review the status of this procedure and to update the advances in anatomic...

متن کاملCadaveric study for ideal dorsal pedicle screw entry point
OBJECTIVE To determine the entry for the dorsal pedicular screw in relation to the notch present at the junction of base of the lateral margin of superior articular process with superior border of transverse process in dorsal spine. The advantage of this technique is a constant and easily identifiable entry point which does not involve partial resection of the inferior facet, thus maintaining s...
متن کاملPosterior atlantal lateral mass fixation technique with polyaxial screw and rod fixation system.
OBJECTIVE Atlantoaxial instability may result from various pathologic conditions and operative treatment may be required to correct the deformity, provide stability and prevent neurological deficits. We presented our clinic's experience using C1-C2 fusion with polyaxial screw and rod fixation for C1 and C2 instability for various reasons. METHODS AND MATERIAL Four patients with atlantoaxial i...
