I used Lanacane medicated body powder for several years (after Zeasorb became unavailable in the UK) but, in turn, Lanacane powder is also now unavailable in the UK. I have anal irritation problems following an anal sphincterotomy in the mid 1980s.
n condition in which the sacrum rotates about an oblique axis so that sacral base side opposite to the axis involved glides anteriorly, producing a deep sulcus. torsion, left-on-left (forward) sacral, n condition in which left rotation of the sacrum occurs about a left oblique axis. torsion, left-on-right (backward) sacral, n condition in which left rotation occurs about a right oblique axis. torsion, right-on-left (backward) , n condition in which right rotation occurs about a left oblique axis.
Sacrum: The sacrum is the wedge-shaped bone consisting of five fused vertebrae, the first of which has a prominent upper border known as the sacral promontory. This is an important pelvic landmark. It projects forward decreasing the anterposterior diameter of the pelvic brim. If this diameter is seriously decreased it can impair the descent of the fetal head into the pelvis. The smooth concave anterior surface is referred to as the hollow of the sacrum and the areas either side are the alae or wings. The convex posterior surface is roughened to receive attachments of muscles. The sacrum is perforated by four sets of holes or foramina through which the sacral nerves pass. Coccyx: The coccyx is at the lower part of the spine and is a vesitigal tail. It is a small triangular-shaped bone consisting of four fused vertebrae.
