Minimally Invasive Atlantoaxial Fixation with a Polyaxial Screw-rod Construct: Technical Case Report

Abstract

Placement of C1 lateral mass and C2 pedicle screws using minimally invasive techniques is technically feasible.

MIS Posterior Cervical Spine Surgery: Five-Level Fusion through a Novel Cervical Tube

“…There are few cases reported in the literature. [8][9][10][11] Wang reported on 3 cases of single-level posterior cervical fusion on traumatic instability achieved through a METRx® tube (Medtronic Sofamor Danek, Memphis, TN). 9 Fong et al reported on two additional patients with trauma requiring a posterior cervical tension band through a METRx® tube.…”

“…Joseffer et al described the use of the Quadrant™ retractor (Medtronic Sofamor Danek, Memphis, TN) to deliver unilateral C1-2 screws for fixation of an Os Odontoideum. 10 The largest series on MIS posterior cervical instrumentation is described by Wang et al 8 They retrospectively reviewed their first 18 patients treated with this technique with two year follow-up. Half of their patients were treated with a single level and half with two-level.…”

Comparative Analysis of Three Different Cervical Lateral Mass Screw Fixation Techniques by Complications and Bicortical Purchase : Cadaveric Study

“…Several studies of the safety and the biomechanical stability of the posterior cervical lateral mass screw have been published 6,12,22,28) . Moreover, the application of the posterior lateral screw fixation method became easier as a result of the development of the polyaxial screw-rod system 7,15,19,21,27) . .…”

“…Several authors have reported that posterior lateral mass screw fixation provides biomechanical stability equal to those of anterior plating or the posterior wiring technique 6,12,22,28) . Moreover, the application of posterior lateral screw fixation became easier as a result of the development of the polyaxial screw-rod system 7,13,19,21,27) . Since the first description of the technique by Roy-Camille et al in 1972, several lateral mass screw fixation techniques have been suggested by Louis, Magerl, Anderson and An 1,2,17,23) .…”

Clinical Applications of the Tubular Retractor on Spinal Disorders

“…The screw fixation and fusion of the first and second cervical vertebras can also effectively be achieved using a tube. There was a report on effective fixation of posterior C1 lateral mass and C2 pedicle screws for Os odontoideum patients 17) . They were alble to insert a C1 lateral mass screw and rod while positioning the tube and adjusting the angle around the C2 lateral mass.…”
