Примери за ischial

• The ischial spines are a landmark for engagement of the fetal head.

• Extending from the middle of the posterior rami of the ischial bones are the ischial spines, which are of great obstetrical importance.

• If one looks at the pelvis, the ischial spines protrude while the curve of the linea terminalis slides downwards, forward and inward.

• The posterior wall of the pelvis is the sacrum, while the lateral walls are formed by the ischial bones, sacrosciatic notches and the pelvic ligaments.

• The mid-pelvis is at the level of the ischial spines.

• Soft tissue landmarks such as tumour and pelvis structures such as anterior sacrum and anterior ischial tuberosity were the exception with overall mean ratings of 'not clear' or 'not visible'.

• The distance between the line connecting the lower poles of the ischial tuberosities and site of abrupt narrowing of contrast material was measured in all 148 patients.

• Ischial containment sockets for amputees are issued on the basis of a clinical decision made by the multi-professional team at a national health service trust.

• It gives twigs to the muscles attached to the ischial tuberosity and anastomoses with the inferior gluteal artery.

• Avulsion fractures occur where muscles are attached: anterior superior and inferior iliac spines, ischial tuberosities, and ischiopubic rami.

• In front of the right ischium muscle fibres are present running from the ischial foot in the direction of the femur.

• The ischial spine separates the greater and lesser sciatic foramina.

• When present it extends towards the ischioanal fossa travelling along the ischial ramus and fusing with the obturator fascia.

• Continuing down the posterior side, the ischial tuberosity is a thick, rough surfaced prominence below the lesser sciatic notch.

• It then crosses the ischial spine, reenters the pelvis through the lesser sciatic foramen, and pierces the pelvic surface of the obturator internus.
