the purpose of this study is to summarize the treatment options for scoliosis and spine deformities from antiquity through medieval times up to the renaissance. furthermore, it is to present the contribution of “the father of modern surgery”, ambroise paré (1510-1590), to this field. paré was a distinguished surgeon of the renaissance with many contributions to surgery, including war trauma, ob...

spine surgery began its evolution in the beginning of the 19th century in order to reach nowadays the point of being considered an important subspecialty of neurosurgery and orthopaedics. the purpose of this historical review is the search and evaluation of the progress in spine surgery in the second half of the 20th century. this review concerns the evolution of this field in greece. special r...

purpose: low back pain is one of the most common musculoskeletal disorders, and lifting is one of its risk factors. the activities of lumbar muscles as the main muscles involved in lifting are important with regard to identification of the allowable limits and the injury mechanisms as well as the motor control aspects. this study aimed to investigate the effects of the lifting speed on the lumb...

background & aim: low back pain is the most debilitating condition, and can lead to decreased physical function, compromised quality of life, and psychological distress. several studies have been conducted to recognize the risk factors of low back pain, but despite of strong relationship between obesity and low back pain, the underlying mechanisms are unclear. the aim of this study was to evalu...

cauda equina syndrome (ces) although uncommon, is a very serious condition, which should be diagnosed as soon as possible.  urinary dysfunction following a lumbosacral trauma is a key for the physician to consider ces as the most probable diagnosis. up to 62% of ces patients report a recent episode of trauma. we herein report a young man with ces due to sacral fracture with an interesting imaging.

the cadaver spine motion segment behavior under torsional load was evaluated with the disc intact, with partial anterior discectomy and with spacer insertion. the results of this study explain how anterior lumbar discectomy and interbody fusion (alif) affects the torsional stability of the motion segment. the pseudarthrosis rate of the anterior lumbar discectomy and interbody fusion (alif) is k...

Detailed investigation on biomechanics of a complex structure such as the human lumbar spine requires the use of advanced computer-based technique for both the geometrical reconstruction and the stress analysis. In the present study, the computer-assisted tomography (CAT) and finite element method (FEM) are merged to perform detailed three dimensional nonlinear analysis of the human ligamentous...
