Charcot spinal arthropathy is a rare, progressive type of vertebral joint degeneration that occurs in the setting of any preexisting condition characterized by decreased afferent innervation to the extent that normal protective joint sensation in the vertebral column is impaired. The authors report on a case of Charcot arthropathy of the lower lumbar spine mimicking a spinal tumor following cer...

seven caspian miniature horses, aged above two years, were used for this study. the skeleton of these horses were cleaned and prepared using appropriate techniques. the vertebral column was studied and photographed. the vertebral column in one of these horses showed variations in thoracic, lumbar and sacral region. the vertebral formola was c7, t19,l5,s6 and a pair of 19th rib was fused with th...

The breeding female or "queen" naked mole-rat has a uniquely elongated body morphology attributed to the lengthening of the lumbar vertebral column that occurs during pregnancy. It is unknown whether this vertebral growth is a continuous process, or associated only with early reproductive experience. We compared pregnancy-related bone elongation in nascent primiparous queens and established que...

Subarachnoid pleural fistula (SPF) following injury to the vertebral column is an extremely rare complication and is usually described after blunt trauma. We report the first case of SPF with pneumocephalus due to a gunshot wound to the spine.

Spinal deformity biomechanics represent a complex topic, as many anatomic and physical variations exist that can affect the biomechanical behavior of the spinal column. Because the Homo sapiens species walks upright, the center of mass lies directly below the vertebral column, which stands in contrast to other vertebrate species [1,2]. In quadrupeds, the center of mass is typically anterior to ...

Traumatic retrolisthesis of the lumbar spine is a rare clinical entity. Only a few case reports have shown retrolisthesis of the fractured fragment over the inferior vertebral body. Fracture dislocations of the spine are unstable injuries that require operative fixation to restore alignment and prevent progressive deformity. We present the case of a traumatic L5-S1 fracture dislocation with ret...

SUMMARY Vertebral hemangiomas are very common abnormalities involving human spinal column. Two different kinds of these lesions, symptomatic and asymptomatic hemangiomas are noted in the spine. The asymptomatic ones are found incidentally in spinal imaging investigations and don not need any theraputic action. The symptomatic hemangiomas, which are not as usual as former one but, causes signif...

The hero shrew's (Scutisorex somereni) massive interlocking lumbar vertebrae represent the most extreme modification of the vertebral column known in mammals. No intermediate form of this remarkable morphology is known, nor is there any convincing theory to explain its functional significance. We document a new species in the heretofore monotypic genus Scutisorex; the new species possesses cran...

This article is a presentation of the concept of the three-column spine. The concept evolved from a retrospective review of 412 thoracolumbar spine injuries and observations on spinal instability. The posterior column consists of what Holdsworth described as the posterior ligamentous complex. The middle column includes the posterior longitudinal ligament, posterior annulus fibrosus, and posteri...

Dra. Rita Delgado – Rua Borges Lagoa 1080 / 307 04038-002 São Paulo SP Brasil. E-mail: ritadelg@yahoo.com.br Chordomas are slow-growing tumors with aggressive local behavior that probably originate from embryonic remnants of the notochord. This is a midline structure along the neural tube that presents involution and fragmentation as ossification of the axial skeleton occurs, in such way that i...
