For 5 patients (age at last follow-up: 5 to 26 years; 2 females), sufficient information was available for inclusion in the case series. 1997; 4 (3):209-23 (ISSN: 1071-9091) Menezes AH. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Os Odontoideum An increased prevalence of osseous abnormalities, such as os odontoideum, os terminale, a bifid arch of the atlas, and hypoplasia of craniovertebral elements, has also been described in this patient population. Rheumatoid arthritis showing pannus formation and bone erosion was the other Various skeletal and non-skeletal anomalies may be seen in association with KFS. Different types of CVJ anomalies may accompany upper cervical KFS. 2 Anatomical Basis of Surgical Approaches to the Region of the Foramen Magnum. CONTENTS 1. Atlantoaxial dislocation (AAD) is often associated with complex deformities of the craniovertebral junction and poses a significant risk of neurological deterioration [1, 2].With regards to its etiology, AAD can be divided into three main categories: traumatic, idiopathic, and deformity-related. A craniovertebral junction and cervical spine magnetic resonance imaging study did not show neural alterations or any other associated abnormalities, such as protrusion of disk material, a syringomyelic cavity, narrowing of the sagittal diameter at the level of the fused segment, compression of the spinal cord, basilar invagination, Chiari malformation, or signs of instability (Fig. The craniovertebral junction (CVJ) is a collective term that refers to the occiput (posterior skull base), atlas, axis, and supporting ligaments. Craniovertebral junction anomalies in inherited disorders: part of the syndrome or caused by the disorder? Y1 - 2018/2. Research paper. ( a) Illustration showing the ossification centers and synchondroses of the atlas. Odontoid fracture predominantly type II was the commonest injury noted. CVJ anomalies are more frequently found in the Indian subcontinent than anywhere else in the world. 1. The development of the craniovertebral junction was present in order to understand the formation of the anomalies discussed. It is a transition zone b/w a mobile cranium & relatively rigid spinal column. Use of 3D printer model to study vertebral artery anatomy and variations in developmental craniovertebral junction anomalies and as a preoperative tool—an institutional experience. A number of classical reviews have attempted to clarify a variety of complex associated issues. The craniovertebral junction is the most complex of the axial skeleton, residing between the skull and the upper cervical spine. Type 2 fractures result from a direct blow to the skull base and occipital condyle, and the intact alar ligaments tend to stabilize the CVJ. Syringomyelia - pathological Rational, ethical and affordable patient care. Neurosurgery is that branch of medicine dealing with surgical treatment of diseases in the brain and spinal cord. It encloses the soft tissue structures of the cervicomedullary junction (medulla, spinal cord, and lower cranial nerves).CONTENTS1. Craniovertebral anomalies. ( a) Illustration showing the ossification centers and synchondroses of the atlas. Recently this has become the preferred procedure. 1. Expanding the phenotype of Wiedemann-Steiner syndrome: Craniovertebral junction anomalies: American Journal of Medical Genetics, Part A Type 1 fractures result from axial compression with comminution of the occipital condyle, and the intact alar ligaments and tectorial membrane tend to stabilize the craniovertebral junction (CVJ). 1 Embryology, Development, and Classification of Disorders of the Craniovertebral Junction. Despite the volumes of publications on the subject, it appears that the last word has not yet been said. Imaging of this complex region and reaching to a specific diagnosis continues to be a challenge for imaging specialists. Craniocervical junction abnormalities are congenital or acquired abnormalities of the occipital bone, foramen magnum, or first two cervical vertebrae that decrease the space for the lower brain stem and cervical cord. Evaluation of congenital anomalies of craniovertebral junction by computed tomography and its embryological basis - IJCAP- Print ISSN No: - 2394-2118 Online ISSN No:- 2394-2126 Article DOI No:- 10.18231/j.ijcap.2019.034, Indian Journal of Clinical Anatomy and Physiology-Indian J Clin Anat Physiol This issue of Acta Neurochirururgica presents the latest surgical and experimental approaches to the craniovertebral junction (CVJ). Craniovertebral junction (CVJ) anomalies can be congenital, developmental or due to malformation secondary to any acquired disease process. These anomalies can lead to cranial nerve compression, vertebral artery compression, and obstructive hydrocephalus. All had genetically confirmed OI type V. Age range at diagnosis of the craniocervical abnormality was 1 day to 18 years. 23 Underlying bone abnormalities at the CVJ can further increase the risk of symptomatic instability. Tuberculosis of craniovertebral junction showing bone erosion and enhancing soft tissue component was the next common abnormality observed. Craniocervical abnormalities were present in 7 of 37 patients with OI type V (19%). Hindbrain herniation syndrome, or Chiari malformation Type I (CM-I), occurs frequently with craniovertebral junction (CVJ) abnormalities when there is reduction in the posterior fossa volume. Conclusion. A higher incidence of C2 segmental type of VA has been found in people with craniovertebral junction (CVJ) anomalies, cases that are more likely to require surgery at the CVJ. Dunsker SB, Brown O, Thomson N. We have tried to clarify this confusing area by demonstrating the common relationships of these abnormalities. This may be due to the fact that craniospinal deformity in … Craniovertebral junction anomalies (Craniocervical junction anomalies) Abstract. The craniovertebral junction (CVJ) is composed of the occiput, the foramen magnum, and the first two cervical vertebrae, encompassing the medulla oblongata and the upper cervical spinal cord. In this article, we have analyzed the surgical outcome after posterior fixation in LS with craniovertebral junction instability. From the clinical perspective, pediatric CVJ lesions can be divided into three categories: developmental bony anomalies with or without instability, stenotic CVJ lesions, and others. This is particularly true in the pediatric population, in which the neurosurgeon is faced with a wide variety of congenital developmental anomalies and acquired diseases and must take into account the need to avoid significant interference ... The subject of craniovertebral junction anomalies is under discussion and evaluation for over a century. ... of excessive movement at the time of ossification of the cartilaginous dens and is exactly analogous to the unfused Type II odontoid fracture. Craniovertebral junction (CVJ) abnormalities or Cranial base abnormalities are one of the most important complication of OI. However, fusion between atlas and axis is not so frequent. Found inside – Page iiThis book will help guide decision-making in surgery using biologic and surgical principles to assist the planning and execution of surgery with available resources. The mucopolysaccharidoses are a group of inherited lysosomal storage diseases that cause disorders in the metabolism of mucopolysaccharides. This review begins with a description of the embryonic developmental process of the CVJ, comprising ossification and resegmentation of the somite. Y1 - 2018/2. Here we describe 11 such individuals, all with KMT2A de novo loss-of-function variants: 10 showed craniovertebral junction anomalies, while an 11th patient had a cervical abnormality in C7.
