Rather than using the Wiberg angle because it makes it difficult to quantify the degree of dislocation they used 3 key elements to determine the degree of subluxation: A reference line at the lower rim of the "teardrop", junction between the femoral head and neck of the respective joint and the height of the pelvis (vertical measurement).
Pelvimetry is the measurement of the female pelvis. [1] It can theoretically identify cephalo-pelvic disproportion, which is when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal. However, clinical evidence indicate that all pregnant women should be allowed a trial of labor regardless of pelvimetry results.
Evaluating the position of the triradiate cartilage on an AP radiograph of the pelvis with both Perkin's line and Hilgenreiner's line can help establish a diagnosis of developmental dysplasia of the hip.
Perkin's line is a line drawn on an AP radiograph of the pelvis perpendicular to Hilgenreiner's line at the lateral aspects of the triradiate cartilage of the acetabulum. [ 1 ] [ 2 ] Clinical use
It refers to the position of a penis as it relates to pathology on an X-ray of a pelvis. When the penis (visible on the X-ray as a shadow) points towards the same side as a unilateral medical condition such as a broken bone, this is considered a "positive John Thomas sign," and if the shadow points to the other side, it is a "negative John ...
The arcuate line of the ilium is a smooth rounded border on the internal surface of the ilium. It is immediately inferior to the iliac fossa and Iliacus muscle. It forms part of the border of the pelvic inlet. In combination with the pectineal line, it comprises the iliopectineal line. [1]
A pelvic examination is the physical examination of the external and internal female pelvic organs. [1] It is frequently used in gynecology for the evaluation of symptoms affecting the female reproductive and urinary tract , such as pain, bleeding, discharge, urinary incontinence , or trauma (e.g. sexual assault).
The linea terminalis or innominate line consists of the pubic crest, pectineal line (pecten pubis), the arcuate line, the sacral ala, and the sacral promontory. [ 1 ] It is the pelvic brim , which is the edge of the pelvic inlet .
