BACKGROUND Biomechanical studies have shown that dynamic stabilization restores the neutral zone and stabilizes the motion segment. Unfortunately, there are limitations to clinical measurement of lumbar motion segments when using routine radiographs. Radiostereometric analysis is a 3-dimensional technique and can measure the spinal motion segment more accurately than techniques using plain film...

STUDY DESIGN Prospective clinical study. OBJECTIVE To test whether elastic stabilization with the Dynesys system (Zimmer Spine, Minneapolis, MN) provides enough stability to prevent further progression of spondylolisthesis as well as instability after decompression for spinal stenosis with degenerative spondylolisthesis. SUMMARY OF BACKGROUND DATA In spinal stenosis with degenerative spondy...

introduction: tonsillectomy is the one of the most common types of surgery in children, and is often accompanied by post-operative pain and discomfort. methods of pain control such as use of non-steroidal anti-inflammatory drugs (nsaids), narcotics, and local anesthetics have been used, but each have their own particular side effects. in this study we investigated the effect of ketamine on post...

objective(s)the purpose of this study holds, for the first time, an evaluation of the intraperitoneal curcumin lavage on the development of post-operative intra-abdominal adhesions.materials and methodsthirty male wistar rats were randomized into five groups. the rats were administered anesthesia and underwent surgery in order to create intra-abdominal adhesions. before the abdomen was closed, ...

background & aim: operation as a stressor can induce physical and psychological negative reactions. considering the anxiety prevalence as the most important sign and symptoms before surgery, on one hand, and the necessity of patients’ mental preparation as the most essential care before surgery, on the other hand, the importance of primary communication of medical centers’ staff would be determ...

septic arthritis of the hip in children has multiple sequelae and may result in severe disability. significant morbidity can be prevented by early recognition and treatment. the authors reviewed 13 children with 14 hips with sequelae of septic arthritis of the hip. all of children had history of hip septic arthritis before age of 4 years. six were male subjects, and 7 were female subjects. we e...

Study Design Retrospective case series. Objective Ankylosing spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH) are two related diseases that significantly increase the risk of unstable spinal fractures from seemingly trivial trauma. Given the older age and higher surgical risk profile of most of these patients, minimally invasive (MIS) approaches to the treatment of such frac...

OBJECTIVE Ankle fractures are one of the most common operatively treated lower extremity fractures. Several studies indicate that patients often have residual effects after this injury. The purpose of this study is to use the SF-36 questionnaire at two times to assess patients' functional recovery and residual effects after operative stabilization of an unstable ankle fracture. DESIGN Twenty ...

Study Design A case report. Background Patients with ankylosing spondylitis have altered spinal biomechanics putting them at increased risk of spinal fractures that are unstable. As a result there is an increasing trend to treat these fractures with surgical stabilization. We hypothesize that the fracture pattern is also an important factor in patients with this disease and that those with an...

chemical stabilization of heavy metals is one of the soil remediation methods based on the application amendments to reduce mobility of heavy metals. a laboratory study was conducted to investigate the influence of different kinds of amendments on cadmium (cd) stabilization in a cd-spiked soil. the amendments were municipal solid waste compost (mswc), coal fly ash (cfa), rice husk biochars prep...
