Spinal fractures in patients with ankylosing spondylitis: A case report and literature review.

Background: Severe ankylosing spondylitis (AS) affects the entire spine, increasing the risk of vertebral fractures. There are several fusion procedures used (e.g.

Acute Neurological Manifestations of Porphyrias and its Types: A Systematic- Review.

Introduction: Acute porphyrias cause life-threatening attacks of neurovisceral non-specific symptoms, so this condition mimics many acute medical and psychiatric diseases. The disease is very misdiagnosed, probably due to its low incidence and non-pathognomonic symptoms, this delays the effective treatment onset. Early diagnosis and treatment highly improve the prognosis and can prevent the development of neuropathic manifestations.

Pseudarthrosis in anterior cervical discectomy and fusion with a self-locking, stand-alone cage filled with hydroxyapatite: a retrospective study with clinical and radiological outcomes of 98 levels with a minimum 2-year follow-up.

Objective: The goal of this study was to evaluate the incidence of pseudarthrosis after the treatment of cervical degenerative disc disease (CDDD) with anterior cervical discectomy and fusion (ACDF) in which self-locking, stand-alone intervertebral cages filled with hydroxyapatite were used.

Methods: The authors performed a retrospective cohort study of 49 patients who underwent 1- to 3-level ACDF with self-locking, stand-alone intervertebral cages without plates, with a minimum 2 years of follow-up. The following data were extracted from radiological and clinical charts: age, sex, time and type of pre- and postoperative signs and symptoms, pain status (visual analog scale [VAS]), functional status (Neck Disability Index [NDI]), history of smoking, bone quality (bone densitometry), and complications.

Idiopathic Ventral Spinal Cord Herniation: Video Report and Systematic Review.

Background: Idiopathic ventral spinal cord herniation (ISCH) is a rare disease; however, it is an important differential diagnosis. Its treatment presents some controversies.

Case Description: We report on a 55-year-old woman who had been presenting with relevant back pain and leg weakness for the past 3 years and urinary incontinence for the past 3 months.

Correlation Between Different Interbody Grafts and Pseudarthrosis After Anterior Cervical Discectomy and Fusion Compared with Control Group: Systematic Review.

Background: Cervical spine degenerative disease is one of the main causes of myelopathy. Anterior cervical discectomy and fusion (ACDF) is the most common surgical procedure used to treat cervical myelopathy. Therefore, it is important to study pseudarthrosis rates after ACDF and correlate them with the graft used.

Multifocal intradural extramedullary ependymoma. Case report.

In this paper, the authors present the case of a patient with multifocal intradural extramedullary ependymoma, and they review 18 previously reported cases. A 32-year-old man presented to the authors' institution with a 1-month history of partial medullary syndrome. Magnetic resonance imaging of the neuraxis revealed multifocal intradural extramedullary lesions at the bulbomedullary junction and C2-3, T5-11, L-2, L-4, L-5, and sacrum.
