Several evolutionary theories have been proposed to explain the adaptation of the long giraffe neck; however, few studies examine the fossil cervical vertebrae. We incorporate extinct giraffids, and the okapi and giraffe cervical vertebral specimens in a comprehensive analysis of the anatomy and elongation of the neck. We establish and evaluate 20 character states that relate to general, crania...

Meningomyelocele: A Rare Case Report We report a case of Klippel-Feil syndrome associated with an anterior cervical meningomyelocele. A 36-year old female patient was referred for evaluation of bilateral symmetric small muscle wasting in both hands. MR images (Fig 1) showed fusion of cervical vertebrae and neural arches. There was an anterior meningomyelocele at the level of C6 and C7. The cerv...

The neck (cervical spine) is a flexible part of the human body and is particularly vulnerable to injury. Patients suspected of cervical spine injuries are often imaged using lateral view radiographs. Incorrect diagnosis based on these images may lead to serious long-term consequences. Our overarching goal is to develop a computer-aided detection system to help an emergency room physician correc...

Klippel-Feil Syndrome (KFS) is a complex, congenital condition, originally described by Maurice Klippel and Andre Feil in 1912.1 It is characterized by congenital fusion of two or more cervical vertebrae. Because of the abnormal fusion process and altered spinal biomechanics with undue motion at the non-fused cervical segment, adjacent to fused segments, such individuals are predisposed to abno...

Sympathetic blocks in the cervical and upper thoracic region are commonly used techniques for a variety of diagnostic, therapeutic and prognostic purposes. Stellate ganglion block is the common nomenclature utilized, however, stellate ganglion is present in only 80% of the population, thus, either lower cervical sympathetic block or upper thoracic sympathetic block is an appropriate term. The c...

Introduction: Diffuse Idiopathic Skeletal Hyperostosis (DISH) is a very rare cause of dysphagia when it occurs in the cervical spine. It can also affect the lumbar region where it causes deformity. Case Report: In this article, a rare case of Diffuse Idiopathic Skeletal Hyperostosis involving both the cervical and lumbar spine, presenting with dysphagia and spinal stiffness leading to a stoopin...

Two extremely-long necked elasmosaurids, AMNH 1495, holotype of Hydralmosaurus serpentinus, and AMNH 5835, previously referred to H. serpentinus, are here reviewed in detail. Unique features of the cervical vertebrae, which are only present on elasmosaurids from the Western Interior Seaway, are recognized based on these specimens and by comparison with penecontemporaneous taxa with biogeographi...

The present study aimed to provide a version of the Cervical Vertebral Maturation (CVM) method for the detection of the peak in mandibular growth based on the analysis of the second through fourth cervical vertebrae in a single cephalogram. The morphology of the bodies of the second (odontoid process, C2), third (C3), and fourth (C4) cervical vertebrae were analyzed in six consecutive cephalome...

In birds, diverticula of the lungs and air sacs pneumatize specific regions of the postcranial skeleton. Relationships among pulmonary components and skeletal regions they pneumatize allow inferences about pulmonary anatomy in non-avian dinosaurs. Fossae, foramina and chambers in the postcranial skeletons of pterosaurs and saurischian dinosaurs are diagnostic for pneumaticity. In basal saurisch...
