Distribution and length of osteophytes in the lumbar vertebrae and risk of rupture of abdominal aortic aneurysms: a study of dry bones from Chiang Mai, Thailand.

Vertebral osteophytes are a characteristic feature of intervertebral disc degeneration. In the lumbar spinal region, the two major structures in close proximity anterior to the spine are the inferior vena cava and the abdominal aorta, both of which have been reported to be affected by osteophytes. The purpose of this study was to determine the distribution, classification and lengths of osteophytes in the lumbar vertebrae.

Anatomical variations of the V2 vertebral artery study by measuring the width of transverse foramen.

Objective: To evaluate the incidence of anatomical variations of the V2 segment of the vertebral artery (VA) using dry bones.

Material And Method: The sample group was 181 cervical spines (equal 362 courses of VA), male 111 and female 70, average age 68 years old (range 26 to 95 years). The width of transverse foramens (TF) was visually inspected, starting at C7, looking upward to find the greatest width of TF meaning the beginning of V2.
