Psoas Sign
The psoas sign, also known as Cope's sign (or Cope's psoas test) or Obraztsova's sign, is a medical sign that indicates irritation to the iliopsoas group of hip flexors in the abdomen, and consequently indicates that the inflamed appendix is retrocaecal in orientation (as the iliopsoas muscle is retroperitoneal). The technique for detecting the psoas sign is carried out on the patient's right leg. The patient lies on his/her left side with the knees extended. The examiner holds the patient's right thigh and passively extends the hip. Alternatively, the patient lies on their back, and the examiner asks the patient to actively flex the right hip against the examiner's hand. If abdominal pain results, it is a "positive psoas sign". The pain results because the psoas borders the peritoneal cavity, so stretching (by hyperextension at the hip) or contraction (by flexion of the hip) of the muscles causes friction against nearby inflamed tissues. In particular, the right iliopsoas muscl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boas' Sign
Boas' or Boas's sign is hyperaesthesia (increased or altered sensitivity) below the right Hypochondrium or 12th rib region, which can be a symptom in acute cholecystitis (inflammation of the gallbladder). It is one of many signs a medical provider may look for during an abdominal examination. Originally this sign referred to point tenderness in the region to the right of the 10th to 12th thoracic vertebrae. It is less than 7% sensitive. Its namesake is Ismar Isidor Boas (1858–1938), a German physician and the first licensed GI specialist in his country. Boas' sign can also indicate stomach and duodenal disease. When the transverse processes of thoracic vertebrae T10-T12 are pressed or effleuraged with the bottom of the hand, pain can appear at the left of spinous processes (in stomach's lesser curvature ulcer) or at the right (in pyloric or duodenal ulcer Peptic ulcer disease (PUD) is a break in the inner lining of the stomach, the first part of the small intestine, or so ...

Supine Position
The supine position ( or ) means lying horizontally with the face and torso facing up, as opposed to the prone position, which is face down. When used in surgical procedures, it grants access to the peritoneal, thoracic and pericardial regions; as well as the head, neck and extremities. Using anatomical terms of location, the dorsal side is down, and the ventral side is up, when supine. Semi-supine In scientific literature "semi-supine" commonly refers to positions where the upper body is tilted (at 45° or variations) and not completely horizontal. Relation to sudden infant death syndrome The decline in death due to sudden infant death syndrome (SIDS) is said to be attributable to having babies sleep in the supine position. The realization that infants sleeping face down, or in a prone position, had an increased mortality rate re-emerged into medical awareness at the end of the 1980s when two researchers, Susan Beal in Australia and Gus De Jonge in the Netherlands, indep ...

Rovsing's Sign
Rovsing's sign, named after the Danish surgeon Niels Thorkild Rovsing (1862–1927), is a sign of appendicitis. If palpation of the left lower quadrant of a person's abdomen increases the pain felt in the right lower quadrant, the patient is said to have a positive Rovsing's sign and may have appendicitis. The phenomenon was first described by Swedish surgeon Emil Samuel Perman (1856-1945) writing in the journal ''Hygiea'' in 1904. In acute appendicitis, palpation in the left iliac fossa may produce pain in the right iliac fossa. Referral of pain This anomaly occurs because the pain nerves deep in the intestines do not localize well to an exact spot on the abdominal wall, unlike pain nerves in muscles. Pain from a stomach ulcer or gallstone can be interpreted by the brain as pain from the stomach, liver, gall bladder, duodenum, or first part of the small intestine. It will "refer" pain often to the mid upper abdomen, the epigastrum. Because the appendix is a piece of inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obturator Sign
The obturator sign, also called Cope's obturator test, is an indicator of irritation to the obturator internus muscle. The technique for detecting the obturator sign, called the ''obturator test'', is carried out on each leg in succession. The patient lies on her/his back with the hip and knee both flexed at ninety degrees. The examiner holds the patient's ankle with one hand and knee with the other hand. The examiner internally rotates the hip by moving the patient's ankle away from the patient's body while allowing the knee to move only inward. This is flexion and internal rotation of the hip. In the clinical context, it is performed when acute appendicitis is suspected. In this condition, the appendix becomes inflamed and enlarged. The appendix may come into physical contact with the obturator internus muscle, which will be stretched when this maneuver is performed on the right leg. This causes pain and is evidence in support of an inflamed appendix. The principles of the obtu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
