article 3 Citação(ões) na Scopus Gunshot wound to the upper cervical spine leading to instability(2014) PAIVA, Wellingson Silva; AMORIM, Robson Luis; MENENDEZ, Djalma Felipe; BROCK, Roger Schmidt; ANDRADE, Almir Ferreira De; TEIXEIRA, Manoel JacobsenGunshot wounds (GSW) to the cervical spine leading to instability are rare. Also, the presence of vital vascular and neurological structures in the surround area lead to death or severe disability in the vast majority of cases. In this brief report, we present a rare case of C1 fracture due to GSW leading to instability of the atlanto-occipital joint in a neurologically intact patient.- Brain Abscess After Halo Fixation for the Cervical Spine(2017) LOPES, Arthur; ANDRADE, Almir; SILVA, Igor; PAIVA, Wellingson; BROCK, Roger; TEIXEIRA, ManoelBACKGROUND: Halo fixation is one of the possible treatments for cervical spine fractures. However, improper use of these devices may lead to many complications, such as pin loosening, halo dislocation, pin site infection, and intradural penetration. CASE DESCRIPTION: We report the case of a 43-year-old man who first presented with a seizure and an altered level of consciousness 5 months after halo-vest placement for an odontoid fracture. Brain imaging showed a brain abscess, under the previous left parietal pin. The patient underwent abscess drainage and antibiotics were administered for 12 weeks. On hospital discharge, he presented with only mild impairments. CONCLUSIONS: Misapplication of halo fixation devices may lead to serious complications, including intracranial pin penetration and brain abscesses. Proper use of the recommended technique may decrease the risk for complications related to the procedure.
- Traumatic Lumbosacral Spondyloptosis in a Pediatric Patient: Case Report and Literature Review(2018) YAMAKI, Vitor Nagai; MORAIS, Barbara Albuquerque; BROCK, Roger Schmidt; PAIVA, Wellingson Silva; ANDRADE, Almir Ferreira de; TEIXEIRA, Manoel JacobsenA 4-year-old girl was admitted to the emergency department after having been buried beneath a wall. A computed tomography scan revealed anterior grade V L5-S1 spondylolisthesis, and magnetic resonance imaging showed a traumatic rupture of the fibrous annulus of the L5-S1 intervertebral disc and lesion of the anterior longitudinal and yellow ligaments. The patient underwent anterior and posterior fixation. Four months later she was able to walk independently, despite a persistent left foot drop. Additionally, we conducted a literature review on lumbosacral spondyloptosis in the pediatric population published between 1990 and 2017. We found 16 cases, 86.6% of which were male, with a mean patient age of 16 +/- 5.05 years. Most patients underwent spine instrumentation. Based on the data reviewed, the neurological status at admission might be a valid predictor of outcome. Pedicle screws are a safe and reliable procedure for stable fixation of the spine in these cases. The removal of screws is discouraged. (c) 2018 S. Karger AG, Basel.

The aim of the present study was describe outcomes in a series of 57 patients with diffuse brain swelling underwent to intracranial pressure (ICP) monitoring. Method: Fifty-eight patients with diffuse posttraumatic brain swelling, were evaluated prospectively. The Glasgow Coma Scale (GCS) scores of patients varied from 4 to 12. Patients groups divided according to GCS and age. Patient neurological assessment was classified as favorable, unfavorable, and death. Results: Mechanisms of injury were vehicle accidents in 72.4% and falls in 15.6%. 54% of patients had GCS scores between 6 and 8. There were no statistical differences, regarding outcome, between groups separated by age. In the adults group (n=47), 44.7% evolved favorably. Conclusion: Our results indicate a poor prognosis in patients with brain swelling. We believe that continuous ventricular CSF drainage with ICP monitoring is a simple method as an adjunct in the management of these patients.bookPart Traumatismo cranioencefálico e raquimedular(2023) AMORIM, Robson Luis Oliveira de; PAIVA, Wellingson Silva; BROCK, Roger Schmidt; ANDRADE, Almir Ferreira de
