We studied prospectively 1381 patients undergoing extradural anaesthesia for total hip or total knee replacement, to determine if extradural anaesthesia can be performed reliably in patients who have had previous lumbar spine surgery. Fifty-two of the 57 patients (91.2%) who had undergone lumbar spine surgery received a successful extradural anaesthetic, and 1307 of 1324 patients without previo...

Osteoporotic patients can present with either single or multiple fractures secondary to repeated falls and progressive osteoporosis. Multiple fractures often lead to additional spinal deformity and are a sign of more severe osteoporosis. In the thoracic spine, multiple fractures are associated with the development of gradual thoracic kyphosis but neurologic deficits are uncommon. In the lumbar ...

[Purpose] We explored the effect of thoracic movement-mediated training (TMMT) on back pain and trunk range of motion (ROM) in a lower back pain (LBP) patient with lumbar flexion rotation syndrome. [Subject] A 55-year-old male LBP patient with lumbar flexion rotation syndrome. [Methods] The subject underwent TMMT, consisting of two thoracic stretching exercises and three thoracic muscle-strengt...

OBJECTIVES This article reviews the prevalence of lumbarisation, sacralisation and lumbar ribs, and their morphological relevance by evaluating multi-slice computed tomography (MSCT) images. These segment variations can cause miscounting of vertebrae at the lumbar spinal level. METHODS A retrospective radiographic analysis of 226 cases scanned by MSCT prior to forensic autopsy was undertaken....

Degenerative changes of the knee often cause loss of extension. This may affect aspects of posture such as lumbar lordosis. A total of 366 patients underwent radiological examination of the lumbar spine in a standing position. The knee and body angles were measured by physical examination using a goniometer. Limitation of extension of the knee was significantly greater in patients whose lumbar ...

To determine the correlation between the bone mineral density (BMD) and spinal mobility and chest expansion index in patients with ankylosing spondylitis. Eighty patients with confirmed diagnosis of ankylosing spondylitis were included in this study. In all of them physical examination was performed including assessment of spinal mobility and chest expansion index. Bone mineral density of the l...

results intraclass correlation coefficient for left and right showed good to high reliability for the cross sectional area of lumbar multifidi (0.74 and 0.88, respectively) as well as the anterior-posterior dimensions of lumbar multifidi (0.89 and 0.91, respectively) and transverse abdomini thickness (0.73 and 0.85, respectively). conclusions rehabilitative ultrasonography is a reliable and non...

Low back pain has for long been associated with the lumbar spine biomechanics. A three dimensional model of segments L2 to L5 of lumbar spine is generated form CT images of a healthy human male. Hounsfield units of the image slices are used to derive material properties throughout the 3D model. This model is subjected to finite element analysis to study stresses developed during naturally found...
