the retrocecal or pelvic region
title: Homans sign text: Homans sign In medicine, Homans' sign (sometimes spelled as Homans sign) or the dorsiflexion sign is considered a sign of deep vein thrombosis (DVT). It was defined by John Homans in 1941 as discomfort behind the knee on forced dorsiflexion of the foot. After surgeons discovered many examples of a false-positive Homans' sign, Homans redefined it in 1944, stating that "discomfort need have no part in the reaction", including increased resistance, involuntary flexure of the knee or pain in the calf to forced dorsiflexion as positive responses. It is estimated to have a sensitivity of 10-54% and a specificity of title: Obturator sign text: 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 obturator sign in the diagnosis of appendicitis are similar to that of the psoas sign. The appendix is commonly located in the retrocecal or pelvic region. The oburator sign indicates the presence of an inflamed pelvic title: Heel tap sign text: Heel tap sign Heel tap sign, also called heel-jar or jar tenderness, is a clinical sign to identify appendicitis. It is found in patients with localized peritonitis. With the patient supine the right heel is elevated by 10-20 degrees is hit firmly with palm of the examiner's hand. The prehospital equivalent of this sign is when pain is elicited as the ambulance hits bumps and potholes during the transport of the patient. Pain may be severe and may radiate to other areas with movement. It is similar to rebound tenderness, but may be easier to elicit when the patient has title: Heel tap sign text: firm abdominal wall muscles. Abdominal pain on walking or running is an equivalent sign. Heel tap sign Heel tap sign, also called heel-jar or jar tenderness, is a clinical sign to identify appendicitis. It is found in patients with localized peritonitis. With the patient supine the right heel is elevated by 10-20 degrees is hit firmly with palm of the examiner's hand. The prehospital equivalent of this sign is when pain is elicited as the ambulance hits bumps and potholes during the transport of the patient. Pain may be severe and may radiate to other areas with movement. It is title: Psoas sign text: 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 muscle lies under the appendix when the patient is supine, so a positive psoas sign on the right may suggest appendicitis. A positive psoas sign may also be present in a patient with a psoas abscess. It may also be positive with other
