Cauda equina syndrome (CES) is a rare but serious neurosurgical emergency that can have devastating longlasting neurologic consequences. CES caused by herniated lumbar discs is rare in the literature. We report an unusual case of incomplete CES due to lumbar disc herniation. The patient presented to our emergency department with acute onset of low back pain, saddle (perineal) anaesthesia, urina...

BACKGROUND The Kineflex lumbar disc is a mechanical, unconstrained, re-centering disc prosthesis developed in South Africa. The first implantation took place in October 2002. We present a single-center, prospective, longitudinal study of the first 100 patients treated with the Kineflex lumbar disc. Our objective was to evaluate the insertion technique, clinical outcomes, and patient satisfactio...

The etiology and clinical picture may be different in children than in adults. Conservative management is the treatment of choice. Tae Kwon Do is a Korean martial art which is notorious for its high...

Objective Morphometric data for the lumbar posterior longitudinal ligament (PLL) was investigated to identify whether there is a difference in the morphometry of the PLL of the lumbar spine at each level with respect to the pattern of intervertebral disc displacement. Methods In 14 formalin-fixed adult cadavers (12 males and 2 females), from L1 to L5, the authors measured the width and height...

INTRODUCTION Herniated lumbar disc is a displacement of disc material (nucleus pulposus or annulus fibrosis) beyond the intervertebral disc space. The highest prevalence is among people aged 30 to 50 years, with a male to female ratio of 2:1. There is little evidence to suggest that drug treatments are effective in treating herniated disc. METHODS AND OUTCOMES We conducted a systematic review...

OBJECTIVE To study changes in midpoint lumbar disc heights in an asymptomatic Jordanian sample relative to age, sex, lumbar level and midvertebral heights. METHODS A total of 153 asymptomatic patients (87 males, age range 20-65 years; mean 43+/-12.1 and 66 females, age range 22-68 years; mean 47+/-13.7) were selected during the study period. All underwent midsagittal magnetic resonance imagin...

Recent biomechanics studies have revealed distinct kinematic behavior of different lumbar segments. The mechanisms behind these segment-specific biomechanical features are unknown. This study investigated the in vivo geometric characteristics of human lumbar intervertebral discs. Magnetic resonance images of the lumbar spine of 41 young Chinese individuals were acquired. Disc geometry in the sa...
