BACKGROUND Klippel-Feil syndrome is defined as congenital fusion of two or more cervical vertebrae and is believed to result from faulty segmentation along the embryo's developing axis during weeks 3-8 of gestation. Persons with Klippel-Feil syndrome and cervical stenosis may be at increased risk for spinal cord injury after minor trauma as a result of hypermobility of the various cervical segm...

For centuries spinal injuries, and in particular those involving the cervical region, have been feared more than any others by the layman because they are so often associated with paralysis and death. A clinical description was recorded in the Edwin Smith papyrus (Power 1934) by a medical author who wrote in 2500 B.C. : “ One having a crushed vertebra of his neck he is unconscious of his two ar...

We report and discuss a combined anterior, anterolateral and posterior approach to the lower cervical spine. This was used for the radical resection of a recurrent osteoblastoma which involved the lateral mass, pedicle, and lamina of the sixth cervical vertebra.

INTRODUCTION Fracture of the atlas was first described by Jefferson (1920). He theorised a bursting mechanism of fracture as the occipital condyles were driven into the atlas. Experimental studies by Hays and Alker (1988) and Panjabi et al (1991) were also conducted to explain the injury mechanisms. Injury mechanisms and fracture patterns are important in the clinical evaluation of spinal injur...

This study investigated the relationship between forward head posture and temporomandibular disorder symptoms. Thirty-three temporomandibular disorder patients with predominant complaints of masticatory muscle pain were compared with an age- and gender-matched control group. Head position was measured from photographs taken with a plumb line drawn from the ceiling to the lateral malleolus of th...

OBJECTIVE There are complications in stand-alone cage assisted anterior cervical discectomy and fusion (ACDF), such as cage subsidence and kyphosis. Here we report our clinical result on ACDF, comparing with stand-alone cages and with cervical plate system for degenerative cervical spine diseases. METHODS Patients with degenerative cervical disease who were diagnosed and treated in Konyang Un...

The formation of foramina transversaria in the seventh cervical vertebra of CBA and C57BL mice and their offspring is found to behave as if it is determined by a single semi-dominant gene. The accessory foramina of Weber (1950) are investigated in the same material. These foramina are classified into two types and their heredity is evaluated.

The etiology of a compressive spinal cord injury can occur secondary to developmental or acquired causes. In horses neurologic gait deficits have been recognized since 1860. In 1938 the term Wobblers syndrome was used to describe these gait abnormalities. There are many terms used to describe this syndrome such as cervical vertebral malformation, cervical vertebral instability, and cervical ver...

The first two cervical vertebrae, C1 and C2, are also known as the atlas and axis, respectively. The odontoid process of C2, also known as the dens, is the superiorly projecting bony prominence from the body of C2 that sits within the anterior portion of the ring of C2. C1 rotates around this. Anterior odontoid screw fixation involves the reduction and stabilization of an odontoid fracture usin...

BACKGROUND While appropriate pillow height is crucial to maintaining the quality of sleep and overall health, there are no universal, evidence-based guidelines for pillow design or selection. We aimed to evaluate the effect of pillow height on cranio-cervical pressure and cervical spine alignment. METHODS Ten healthy subjects (five males) aged 26 ± 3.6 years were recruited. The average height...
