Spine surgery in patients with ankylosing spondylitis

Britto,Natália Maria Fernandes; Renor,Beatriz Souza; Ghizoni,Enrico; Tedeschi,Helder; Joaquim,Andrei Fernandes

SUMMARY INTRODUCTION: Ankylosing spondylitis (AS) is an idiopathic seronegative spondyloartropathy that involves mainly the axial skeleton and the sacroiliac joints. AS promotes biomechanical changes in the spine that predispose to fractures, spinal deformity and spondylodiscitis. The aim of this article is to report the clinical and laboratorial characteristics of patients with AS who underwent spinal surgery ...

Posterior fossa decompression with duraplasty in Chiari surgery: A technical note

Sabba,Marcelo Ferreira; Renor,Beatriz Souza; Ghizoni,Enrico; Tedeschi,Helder; Joaquim,Andrei Fernandes

Summary Chiari malformation (CM) is the most common and prevalent symptomatic congenital craniocervical malformation. Radiological diagnosis is established when the cerebellar tonsils are located 5 mm or more below the level of the foramen magnum on magnetic resonance imaging (MRI). Surgical treatment is indicated whenever there is symptomatic tonsillar herniation or syringomyelia/hydrocephalus. The main surgic...

3-D simulation of posterior fossa reduction in Chiari I

Fernandes,Yvens Barbosa; Perestrelo,Pedro Fábio Mendonça; Noritomi,Pedro Yoshito; Mathias,Roger Neves; Silva,Jorge Vicente Lopes da

ABSTRACT We proposed a 3D model to evaluate the role of platybasia and clivus length in the development of Chiari I (CI). Using a computer aided design software, two DICOM files of a normal CT scan and MR were used to simulate different clivus lengths (CL) and also different basal angles (BA). The final posterior fossa volume (PFV) was obtained for each variation and the percentage of the volumetric change was ...
