Retroperitoneal abscess complicated with necrotizing fasciitis of the thigh in a patient with sigmoid colon cancer.

5 Oct 2009 BACKGROUND: Necrotizing fasciitis of the thigh due to the colon cancer, especially during chemotherepy, has not been previously reported. CASE PRESENTATION: A 67-year-old man admitted to the hospital was diagnosed with sigmoid colon cancer that had ... Read more...

Precision of traditional approaches for lumbar plexus block: impact and management of interindividual anatomic variability.

30 Aug 2009 BACKGROUND: Traditional methods for approaching the lumbar plexus from the posterior rely on finding the intersection of lines that are drawn based on surface landmarks. These methods may be inaccurate in many cases. The aim of this study was to ... Read more...

The mechanical behavior of individual sarcomeres of myofibrils isolated from rabbit psoas muscle.

24 Aug 2009 The goal of this study was to develop a system to experiment with sarcomeres mechanically isolated from skeletal muscles. Single myofibrils from rabbit psoas were transferred into a temperature-controlled (22 degrees C or 15 degrees C) experimental ... Read more...

Technical information about 'Psoas Muscles'

Definition: A powerful flexor of the thigh at the hip joint (psoas major) and a weak flexor of the trunk and lumbar spinal column (psoas minor). Psoas is derived from the Greek "psoa", the plural meaning "muscles of the loin". It is a common site of infection manifesting as abscess (PSOAS ABSCESS). The psoas muscles and their fibers are also used frequently in experiments in muscle physiology.
