What's the difference between ischium and sacrosciatic?
Ischium
Definition:
(n.) The ventral and posterior of the three principal bones composing either half of the pelvis; seat bone; the huckle bone.
(n.) One of the pleurae of insects.
Example Sentences:
(1) For the sternum, humerus and ilium-ischium, however, ossification in A2 fetuses increased to the levels observed in the PF and C groups.

(6) Sites of involvement included the pubis in three patients, the ilium in two patients, and the ischium in one patient.
(7) Increasing the protein content of the alcohol diet from 18% (Diet A1) to 25% (Diet A2) significantly increased ossification of the ulna, sternum, humerus and ilium-ischium.
(8) A training and monitoring system has been developed to train spinal cord injured patients to relieve pressure intermittently from ischium while sitting in wheelchairs.
(9) Surgical repair with reattachment of avulsed muscles to the ischium and proximal tendinous sheaths of the muscles restored function or corrected deformity.
(10) In older children in whom rigidity of the pubic symphysis did not permit a sufficient amount of acetabular tilt the acetabulum had to be isolated from the rest of the pelvis by a triple osteotomy which consisted of, in addition to the osteotomy of the ilium, osteotomies of the superior pubic ramus and the ischium or the inferior pubic ramus.
(11) Bicortical fixation was significantly greater in the superior ilium, posterior column, and ischium than in the anterior column or pubis.
(12) According to NOVOTNY, a correct sexing of pelves is possible on the basis of combination of 2 type-morphognostic characters and 4 morphometric ones of the pubis, the ischium, and the greater sciatic notch (incisura ischiadica major).
(13) The bony hemipelvis was resected in the subperiosteal plane, resulting in the removal of the iliac wing, ischium, and pubic rami.
(14) The results show that the main stressing of the bony pelvis occurs in the region of the acetabulum and the iliosacral joints, and that further points of loading are located in the lower region of the ischium-and this while standing on one leg, on the side of the supporting leg.
(15) The involved portions of the left pubis and left ischium presented as "cold" areas on the original bone scan with 99mTc-diphosphonate.
(16) A benign osteoblastoma of the anterior part of the pelvic ring was excised with the pubic rami ischium and lower part of the acetabulum.
(17) It is secondary to impairment of the internal pudendal nerve in its musculo-osteo-aponeurotic tunnel composed by the ischium and the obturator internus muscle (ischiorectal fossa or pudendal canal).
(18) Ischium and pubis remained unossified until the 20th day of gestation.
(19) A worst-case support condition was assumed in which bony contact with small areas of the ilium, ischium, and pubis was represented by three-point support.
(20) Conservative hemipelvectomy is the resection of the ischium, ilium and subjacent extremity.
Sacrosciatic
Definition:
(a.) Of or pertaining to both the sacrum and the hip; as, the sacrosciatic foramina formed by the sacrosciatic ligaments which connect the sacrum and the hip bone.
Example Sentences:
(1) The patient was then positioned so that the shock waves entered below the sacrosciatic notch.
(2) Quantitative comparison of pre- and postcontrast scans was performed at two levels: at the mid-liver to assess hepatic enhancement and 1 cm above the sacrosciatic notch to assess pelvic vascular enhancement.
(3) Viral assays performed on appropriate tissues at various time intervals indicated that the infection progressed sequentially from peripheral to the central nervous system, with infectious virus reaching the sacrosciatic spinal ganglia in 20 to 24 hr.
(4) These include: (1) along the psoas muscle deep to the inguinal ligament; (2) through the femoral canal; (3) by way of the obturator foramen; and (4) through the sacrosciatic notch.
(5) In attempts to reactivate latent herpes simplex virus, we instilled Diplococcus pneumoniae intratracheally into mice harboring latent infections in sacrosciatic spinal ganglia.
