Numerical Variations in Human Vertebral Column

Anatomical Variations of Vertebral Artery

Introduction: Vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. They ascend the neck to enter the cranial cavity and supply blood to the brain. Methods: A total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. This study was conducte...

Variations and Anomalies of the Vertebral Column in Lithuanian Palaeoosteological Samples

Skeletons of 857 adult individuals from various selected samples were examined and detected variations and anomalies of the vertebral column were classified either as ontogenetic, phylogenetic or of mixed origin. The conclusion was made that ontogenetic and phylogenetic variations are definitely different types of individual variability. While ontogenetic variations (of vertebral bodies and arc...

Hydatid Disease of Vertebral Column

A 30 years old male presented to us with history of back pain and weakness of both lower limbs for the last four months and was diagnosed by local orthopedic surgeon as a case of carries spine. He also used anti tuberculous drugs for two months but there was no improvement in his symptoms. We planned for transpedicular spinal biopsy. Biopsy report came to be non specific chronic inflammation. W...

Tumors of the vertebral column.

The clinical is, in most instances, non-specific. Pain is a common symptom, and may be spontaneous or be of a mechanical nature. It may simulate all the clinical syndromes of the degenarative spinal disorders, and thus it is not surprising that the correct diagnosis is often quite delayed. An expanding mass, which may reach considerable size is another manifestation. Finally as the tumor encroa...
