There have been reports of abnormalities in the lumbosacral region involving a lower-than-normal termination of the dural sac, which is caused by disease or anatomical variation. Inadvertent dural puncture or other unexpected complications can occur during caudal epidural block or adhesiolysis in patients with these variations, but only a small number of case reports have described this issue. ...

A 15-YEAR-OLD HISPANIC BOY WITH A MEDIcal history of seborrheic dermatitis and mild facial acne was referred to the pediatric dermatology department for evaluation of “red-purple streaks” on his lumbosacral region. His pediatrician had referred him owing to concern of physical abuse by his parents; his case had been reported to the Department of Children and Families. The patient and his family...

Lumbosacral Transitional Vertebrae (LSTV) is the rare medical term used to describe congenital or acquired of lumbosacral vertebral junction abnormalities associated with without pain at lower back (Almeida, et al. [1]).

Introduction. The lateral lumbar interbody fusion (LLIF) surgical approach has potential advantages over other approaches but is associated with some unique neurologic risks due to the proximity of the lumbosacral plexus. The present study analyzed complications following LLIF surgical approach using a novel single flat-blade retractor system. Methods. A retrospective data collection of patient...

A biomechanical model of the lumbosacral region was constructed for the purpose of systematically studying the combined stresses and strains on the local ligaments, muscles and disc tissue during sagittal plane two-handed lifting. The model was validated in two ways. The first validation was a comparison of experimental study results with model predictions. In general predictions compared very ...

Eighteen Functional Spinal Units (FSU), representing three levels of human lumbar and lumbosacral spine, were tested using preload forces that corresponded to the clinical situation of a person lying supine or standing while subjected to maximum physiologic flexion or extension forces. Sagittal plane displacements were measured using linear variable differential transformers (LVDTs) and a MINC-...

Great interest is being shown in sciatica at the present time. It is a common disturbance of obscure etiology. Its association with rheumatism and trauma renders it a severe economic problem, in war as in peace. An advance in the understanding of some forms of sciatica has been made in the recognition of the important part played by intervertebral disc lesions (Alajouanine and Petit-Dutaillis. ...

Teratological spondylolysis is a pathological entity noted for the first time in the specialty literature by Gh. Burnei in "The Spine Journal", in September 25, 2014. This disease was described in a short presentation of the first case treated by the author. The aim of this paper was to expose in a didactic manner the main characteristic aspects of Burnei's disease: embryological, clinical, ima...

Surface electrodes have been used to record potentials evoked in the lumbosacral region of 15 healthy volunteers after tibial nerve stimulation. By monitoring the M waves and H reflexes in the triceps surae muslces and by comparing the responses recorded over the roots with those over the lower cord, it was possible to identify the neural substrates responsible for several of the components in ...
