Craniovertebral realignment for basilar invagination and atlantoaxial dislocation secondary to rheumatoid arthritis.
OBJECTIVE We present our experience of treating nine consecutive cases of rheumatoid arthritis involving the craniovertebral junction by atlantoaxial joint manipulation and attempts towards restoration of craniovertebral region alignments. MATERIAL AND RESULTS Between November 2001 and March 2004, nine cases of rheumatoid arthritis involving the craniovertebral junction were treated in our de...
متن کاملSurgical Management of Adult Reducible Atlantoaxial Dislocation, Basilar Invagination and Chiari Malformation with Syringomyelia.
AIM To analyze retrospectively the surgical management of reducible atlantoaxial dislocation (AAD), basilar invagination (BI) and Chiari malformation (CHM) with syringomyelia through a single-stage posterior approach. MATERIAL AND METHODS Forty-three patients with reducible AAD, BI and CHM with syringomyelia underwent surgery from January 2009 to January 2013. Intraoperative restoration follo...
متن کاملOrientation of C1-2 Joints in Congenital Atlantoaxial Dislocation
Aim: To study the C1-2 facets in patients with congenital atlantoaxial dislocation and their bearing on the presentation and management. Materials and methods: Thirty-six patients of congenital AAD were studied in the last 2 years. Twenty-four patients had irreducible AAD (not reducing on traction) and remaining 12 had redu cible AAD. Computed tomography (CT) scans were obtained and the C1-2 jo...
متن کاملCompression-distraction reduction surgical verification and optimization to treat the basilar invagination and atlantoaxial dislocation: a finite element analysis
BACKGROUND Basilar invagination (BI) combined with atlantoaxial dislocation (AAD) leads to foramen magnum stenosis and medullary spinal cord compression, causing nerve dysfunction. The purpose of the surgery is to remove the bony compression at brainstem ventral side and fix the unstable spinal segment and make it fused stably. Occipital cervical internal fixation system that simultaneously red...
