SYN: round p..- p. minor [TA] SYN: lesser p..- Nägele p. an obliquely contracted or unilateral synostotic p., marked by arrest of development of one lateral half of the sacrum, usually ankylosis of the sacroiliac joint on that side, rotation of the sacrum toward the same side, and deviation of the symphysis pubis to the opposite side.- p. nana SYN: dwarf p..- p. obtecta a form of kyphotic p. in which the angular curvature of the spine is low and extreme so that the spinal column projects horizontally across the inlet of the p..- osteomalacic p. a pelvic deformity in osteomalacia; the pressure of the trunk on the sacrum and lateral pressure of the femoral heads produce a pelvic aperture that is three-cornered or has the shape of a heart or a cloverleaf, while the pubic bone becomes beak shaped. SYN: beaked p., rostrate p..- p. plana SYN: flat p..- platypellic p. flat oval p., in which the transverse diameter is more than 3 cm longer than the anteroposterior diameter.- Prague p. SYN: spondylolisthetic p..- pseudoosteomalacic p. an extreme degree of rachitic p., resembling the puerperal osteomalacic p., in which the pelvic canal is obstructed by a forward projection of the sacrum, and an approximation of the acetabula.- rachitic p. a contracted and deformed p.; most commonly, a flat p. occurring from rachitic softening of the bones in early life.- renal p. [TA] a flattened funnel-shaped expansion of the upper end of the ureter receiving the calices, the apex being continuous with the ureter. SYN: p. renalis [TA], ureteric p..- p. renalis [TA] SYN: renal p..- reniform p. a modified cordate p., with a long transverse diameter, giving the brim a kidney shape.- Robert p. obsolete term for a p. that is narrowed transversely in consequence of the almost entire absence of the alae of the sacrum.- round p. SYN: mesatipellic p..- rubber p. SYN: caoutchouc p..- small p. SYN: lesser p..- split p. a p. in which the symphysis pubis is absent, the pelvic bones being separated by quite an interval; usually associated with exstrophy of the bladder.- spondylolisthetic p. a p. whose brim is more or less occluded by a forward dislocation of the body of the lower lumbar vertebra. SYN: Prague p., Rokitansky p..- p. spuria SYN: greater p..- true p. SYN: lesser p..- p. vera SYN: lesser p..
* * *1) a basin-shaped structure in the skeleton of many vertebrates that is formed by the pelvic girdle together with the sacrum and often various coccygeal and caudal vertebrae and that in humans is composed of the two hip bones bounding it on each side and in front while the sacrum and coccyx complete it behind2) PELVIC CAVITY3) RENAL PELVIS
* * *n. (pl. pelves)1. the bony structure formed by the hip bone, sacrum, and coccyx: the bony pelvis. The hip bones are fused at the back to the sacrum to form a rigid structure that protects the organs of the lower abdomen and provides attachment for the bones and muscles of the lower limbs.2. the lower part of the abdomen.3. the cavity within the bony pelvis.4. any structure shaped like a basin, e.g. the expanded part of the ureter in the kidney (renal pelvis).• pelvic adj.
* * *pel·vis (pelґvis) pl. pelґves [L. â€œbasinâ€] 1. [TA] the inferior portion of the trunk of the body, bounded anteriorly and laterally by the two hip bones and posteriorly by the sacrum and coccyx; see illustration. The pelvis is divided by a plane passing through the terminal lines into the p. major superiorly and the p. minor inferiorly. The superior boundary of the pelvic cavity is the inlet (apertura pelvis superior [TA]), and the inferior boundary of the pelvis minor is the outlet (apertura pelvis inferior [TA]), which is bounded by the coccyx, the symphysis pubis, and the ischium of either side. The outlet is closed by the coccygeus and levator ani muscles and the perineal fascia, which form the floor of the pelvis. The inlet and outlet each have three important diameters: an anteroposterior (conjugate), an oblique, and a transverse, the relations of which determine types variously classified by different authors (see illustration under diameter). 2. any basinlike structure.
Anterior aspect of female (A) and male (B) pelvis.
