Review Article - Atlantoaxial fixation: Overview of all techniques [PDF]

, 2005
Over the past century, steady advances have been made in fixating an unstable atlantoaxial complex. Current options for fixation of the atlantoaxial complex include posterior clamps, posterior wiring techniques, C1-C2 transarticular screw fixation ...

The importance of atlantoaxial fixation after odontoidectomy [PDF]

Journal of Neurosurgery: Spine, 2016
OBJECT Although anterior odontoidectomy has been widely accepted as a procedure for decompression of the craniovertebral junction (CVJ), postoperative biomechanical instability has not been well addressed. There is a paucity of data on the necessity for and choice of fixation.

Atlantoaxial fixation–anterior or posterior approach: Critical review

Journal of Spinal Surgery, 2016
Atlantoaxial facet joints have been proposed as the center of mobility and also center for instability of the atlantoaxial region. Because of the high mobility of the atlantoaxial (C1-C2) motion segment, fusion rates at this level have been substantially

Atlantoaxial fixation: Overview of all techniques [PDF]

Neurology India, 2005
Over the past century, steady advances have been made in fixating an unstable atlantoaxial complex. Current options for fixation of the atlantoaxial complex include posterior clamps, posterior wiring techniques, C1-C2 transarticular screw fixation, posterior C1 lateral mass screw with C2 pars or pedicle screw fixation, and anterior transoral C1 lateral

Differences in fixation strength among constructs of atlantoaxial fixation [PDF]

Journal of Neurosurgery: Spine, 2019
OBJECTIVETo avoid jeopardizing an aberrant vertebral artery, there are three common options in placing a C2 screw, including pedicle, pars, and translaminar screws. Although biomechanical studies have demonstrated similar strength among these C2 screws in vitro, there are limited clinical data to address their differences in vivo. When different screws

Role of Posterior Interfacetal Distraction and Grafting in Complex Atlantoaxial Dislocation

Egyptian Spine Journal, 2019
Background Data: Atlantoaxial fixation, unlike subaxial spine, is still challenging due to complex topographical anatomy. Nowadays, atlas lateral mass screws and transpedicular axis screws fixation is a well-accepted technique for the management of ...

Surgical Management for Posterior Atlantoaxial Dislocation without Fracture and Atlantoaxial Dynamic Test to Confirm the Integrity of the Transverse Ligament: A Case Report

Orthopaedic Surgery, 2022
Background Traumatic posterior atlantoaxial dislocation (PAAD) without fracture of the odontoid process is a rare injury. Closed reduction by skull traction under C‐arm fluoroscopic guidance and open reduction have been reported previously for the ...

Atlantoaxial rotatory fixation – a cause of torticollis [PDF]

Tidsskrift for Den norske legeforening, 2013
A rare, but important cause of torticollis in children is atlantoaxial rotatory fixation. If the patient remains undiagnosed for more than three months, surgery is generally the only therapeutic alternative. In this article we present our experiences of surgical treatment of late-diagnosed atlantoaxial rotatory fixation in children.This article is ...

Atlantoaxial Instability after Treatment of Atlantoaxial Rotatory Fixation: A Case Report

Journal of Orthopaedic Case Reports, 2023
Introduction: We encountered a case of atlantoaxial subluxation (AAS) after treatment of atlantoaxial rotatory fixation (AARF). Reports of developing AAS after AARF are extremely rare. Case Report: An 8-year-old male who feels neck pain was diagnosed with AARF type II according to the Fielding classification.

Is C2-3 fusion an evidence of atlantoaxial instability? An analysis based on surgical treatment of seven patients

Journal of Craniovertebral Junction and Spine, 2020
Objective: The authors analyze the rationale of atlantoaxial fixation in patients presenting with symptoms related to cervical myelopathy and wherein the radiological images depicted C2–3 fusion and presence of single or multiple level neural compression
