Abstract

An experimental study of experimental burst fractures in bovine spinal specimens was conducted to analyze the effects of transpedicular short-segment posterior fixation followed by reduction on indirect spinal canal decompression. For this purpose, experimental burst fractures were created in 11 bovine specimens with a hydraulic materials-testing machine. The specimens were evaluated with plain radiographs and CT scans before reduction. Thereafter, they were instrumented with titanium transpedicular screws and rods (short-segment posterior fixation); and reduction was achieved which included distraction and kyphosis correction maneuvers. Each spinal specimen was evaluated with plain radiographs and CT scans after reduction by applying distraction and kyphosis correction maneuvers. Plain radiographic analysis showed that the kyphosis angle and segmental height values improved. Furthermore, CT scans revealed that the spinal canal diameter values improved compared with those before reduction. The differences between before and after reduction in kyphosis angle, segmental height, anterior body compression, and percentage of retropulsion were statistically significant. Short-segment posterior fixation followed by indirect spinal can...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
