Decompressive cervical laminectomy and lateral mass screw-rod arthrodesis. Surgical analysis and outcome

A retrospective review of total 785 lateral mass screws were placed in patients ages 16-68 years (40 females and 70 males). All cases were performed with a polyaxial screw-rod construct and screws were placed by using Anderson-Sekhon trajectory. Most patients had 12-14-mm length and 3.5 mm diameter screws placed for subaxial and 28-30 for C1 lateral mass. Screw location was assessed by post operative plain x-ray and computed tomography can (CT), besides that; the facet joint, nerve root foramen and foramen transversarium violation were also appraised.No patients experienced neural or vascular injury as a result of screw position. Only one patient needed screw repositioning. Six patients experienced superficial wound infection. Fifteen patients had pain around the shoulder of C5 distribution that subsided over the time. No patients developed screw pullouts or symptomatic adjacent segment disease within the period of follow up.decompressive cervical spine laminectomy and Lateral mass screw stabilization is a technique that can be used for a variety of cervical spine pathologies with safety and efficiency.Posterior cervical fixation with lateral mass screws was first introduced by Roy-Camille in 1979; it has been increasingly used since that time to treat a wide range of cervical spine disorders [1]. posterior cervical fixation was frequently involved in form of wire and bone construct fixation. With a proven long-term effectiveness, and requires no special skills or x-ray guidance [2-4]. posterior cervical wire fixation may not be efficient in osteoporotic patient, as this technique can compromise the posterior cervical elements and may result in aggravating the primary pathology and worsen up the neurological status that requires full fixation by using the lateral mass fixation technique [5-7]. Furthermore, Stainless-steel wire can interfere with postoperative magnetic resonance (MR) imaging results, in contrast to the MRI compatible titanium screw/rod constructs. La
