BACKGROUND There is a controversy regarding the treatment of lumbar disc herniation. Most of patients with lumbar disc herniation and radiculopathy improve with rest and medicine. Lumbar disc surgery gives rapid relief to the patients with severe root pain in legs. This study was conducted to see the risks and benefits of surgery in single level symptomatic lumbar disc disease. METHODS This p...

BACKGROUND The purpose of orthognathic surgery is to correct facial deformity and dental malocclusion and to obtain normal orofacial function. However, there are controversies of whether orthognathic surgery might have any negative influence on temporomandibular (TM) joint. The purpose of this study was to evaluate the influence of orthognathic surgery on articular disc position and temporomand...

BACKGROUND Magnetic Resonance Imaging (MRI) is considered the mainstay imaging investigation in patients suspected of lumbar disc herniations. Both imaging and clinical findings determine the final decision of surgery. The objective of this study was to assess MRI observer variation in patients with sciatica who are potential candidates for lumbar disc surgery. METHODS Patients for this study...

background: intervertebral disc herniation is a major cause of low back pain. several treatment methods are available for lumbar disc herniation including chemonucleolysis, open surgery, nucleoplasty, laser disc decompression, and intradiscal electrothermal therapy. the high prevalence of lumbar disc herniation necessitates a minimally invasive yet effective treatment method. in this study, we ...

background: literature recommends that refractory cases with lumbar disc herniation and appropriate indications are better to be treated surgically, but do all the patients throughout the world consent to the surgery with a same disability and pain threshold? we aim to elucidate the prevalence and severity of disabilities and pain in iranian patients with lumbar disc herniation who have consent...

As a new choice for the treatment of degenerative lumbar disease, artificial lumbar disc replacement has been widely used in clinical surgery. The finite element is a very effective method to predict and simulate the surgery effect. The purpose of this paper is to review the applications of finite element in artificial lumbar disc replacement, such as design of artificial lumbar disc prosthesis...
