Literature on the anatomy of the human vertebral column characterizes the shape of the lumbar vertebral canal as triangular. The purpose of the present study was to determine the precise shape of the lumbar vertebral canal. Ten lumbar vertebral columns of adult male cadavers were dissected. Two transverse sections were performed in the third lumbar vertebra. One section was performed at the lev...

BACKGROUND The aim of this report is to present a case of spontaneous regression of traumatic lumbar epidural hematomas. CASE REPORT A 45-year-old man presented at our clinic after falling from a height. After admission, anterior compression was detected by X-ray, so lumbar spinal CT was performed. For ligament damage, emergency MR was performed. There was acute hematoma at 1 cm diameter, whi...

A 41-year-old white female patient with complaints of lumbar pain for more than three years, without irradiation, underwent several radiological examinations. Her condition was diagnosed by means of biopsy, as monostotic Paget' s disease in the third lumbar vertebra. This is an uncommon location.

A 44-year-old male presented with acute onset retention of urine and low back pain. Magnetic resonance imaging (MRI) of the lumbar spine demonstrated an extradural mass extending from the lower border of the L3 vertebra to upper border of L5 vertebra. Axial imaging showed the posterolaterally located mass lesion on left side, producing significant compression and displacement of thecal sac and ...

[Purpose] This study assessed vertebral and femoral bone mineral density in adult females. [Subjects and Methods] A total of 314 females in their 40s to 70s were divided into normal, osteopenia, and osteoporosis groups and their vertebral and femoral bone mineral densities were compared. [Results] Comparisons of T scores revealed significant differences among measurements of the third lumbar ve...

Thallium 201 whole body scintigraphy was performed in a 30 year old patient with diffuse osseous metastatic disease secondary to glioblastoma multiforme. Multiple sites of Thallium uptake correlated with the findings on serial bone scans and radiographs. Bone biopsy of a lower lumbar vertebra confirmed that the metastases were of glial origin.

The lumbar multifidus muscle was dissected with particular reference to its innervation in 10 Japanese adults and 10 fetuses from 5 to 10 months old. The results were as follows: 1) The multifidus muscle attached to the spinous process of a lumbar vertebra was segmentally innervated by the medial branch of the dorsal ramus of the lumbar nerve on a level with the spinous process. 2) The motor po...

Substantial data exist from cadaveric and magnetic resonance imaging studies regarding the position of the conus medullaris in normally developed adults. However, no large studies have documented the position of the conus medullaris in patients with diagnosed lumbar spinal stenosis. To goal of the current study was to determine the position of the conus medullaris within a living adult populati...
