    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 Jacobsen
    Gunshot 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.

    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 Jacobsen
    A 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.

    Intraoperative Ultrasonography for Definition of Less Invasive Surgical Technique in Patients with Chiari Type I Malformation
    (2017) BROCK, Roger Schmidt; TARICCO, Mario Augusto; OLIVEIRA, Matheus Fernandes de; OLIVEIRA, Marcelo de Lima; TEIXEIRA, Manoel Jacobsen; BOR-SENG-SHU, Edson
    INTRODUCTION: Chiari malformation type I (CM) is the main congenital malformation disease of the craniovertebral junction. The ideal surgical treatment is still controversial. Invasive procedures inside the cerebrospinal fluid (CSF) space and associated with dural repair are considered the gold standard; however, less invasive surgery with isolated bone decompression without dural opening may be possible in selected patients. Our study evaluates the efficacy of intraoperative CSF flow measurement with ultrasonography (USG) as a determining parameter in the selection of these patients. METHODS: We analyzed prospectively 49 patients with CM operated on at the Hospital das Clinicas, College of Medicine, University of Sao Paulo. Patients underwent decompressive surgery with or without opening of the dura mater after intraoperative USG measuring flow rate. A value of 3 cm/second was considered a cutoff. Quality of life before and after surgery and the improvement of neck pain and headache were evaluated. RESULTS: Among 49 patients enrolled, 36 patients (73%) had CSF flow >3 cm/second and did not undergo duraplasty. In 13 patients (27%) with initial flow <3 cm/second, dural opening was performed together with duraplasty. All patients improved when preoperative and postoperative scores were compared, and all clinical parameters evaluated did not differ between both surgical groups. Patients submitted to bone decompression alone had a lower complication rate. CONCLUSIONS: Intraoperative USG with measurement of CSF allows the proper selection of patients with CM for less invasive surgery with bone decompression without duraplasty.

    Cerebellopontine angle empyema after lumbar disc herniation surgery
    (2015) NASCIMENTO, Clarissa Gambara; BROCK, Roger Schmidt; MORAIS, Barbara Albuquerque; TAVARES, Wagner Malago; TEIXEIRA, Manoel Jacobsen; PAIVA, Wellingson Silva
    Background: Lumbar discectomy is still one of the most common spinal surgeries performed today. Nevertheless, there are few publications considering severe complications. Case Description: We report a case with severe complication, without any previous report, a brain empyema after cerebrospinal fluid leak with good outcome afterword. A 45 years old man, returned six days after surgery, presenting cerebrospinal fluid leak, which after clinical and laboratory deterioration was reoperated. In the 14th postoperative facing worsening level of consciousness was diagnosed empyema in cerebellopontine angle and hydrocephalus underwent emergency surgery. Evolved with hemiplegia in the first postoperative attributed to vasculitis, completely recovered after 5 days. Conclusions: Although infrequent, lumbar discectomy is subject to severe complications, which as the case presented, can be dramatic. In surgeries must be careful to avoid cerebrospinal fluid leak e infectious complications.
