It runs from the sacrum (the lower transverse sacral tubercles, the inferior margins sacrum and the upper coccyx [1]) to the tuberosity of the ischium. It is a remnant of part of biceps femoris muscle. The sacrotuberous ligament is attached by its broad base to the posterior superior iliac spine, the posterior sacroiliac ligaments (with which ...
Behind it is a rough surface, the sacral tuberosity, on which are three deep and uneven impressions, for the attachment of the posterior sacroiliac ligament. The lower half is thin, and ends in a projection called the inferior lateral angle.
The posterior sacroiliac ligament is situated in a deep depression ... it is attached by one extremity to the third transverse tubercle of the back of the sacrum, ...
The posterior border of the ala of sacrum, shorter than the anterior, also presents two projections separated by a notch, the posterior superior iliac spine and the posterior inferior iliac spine. The posterior superior iliac spine serves for the attachment of the oblique portion of the posterior sacroiliac ligaments and the multifidus.
The iliac tuberosity is part of the anatomy of the ilium portion of the hip bone. Behind the iliac fossa is a rough surface, divided into two portions, an anterior and a posterior. [ 1 ] The posterior portion, the iliac tuberosity , is elevated and rough, for the attachment of the posterior sacroiliac ligaments and for the origins of the ...
The anterior surface (auricular surface), so called from its resemblance in shape to the ear, is coated with cartilage in the fresh state, and articulates with a similar surface on the side of the sacrum. The posterior portion, known as the iliac tuberosity, is elevated and rough, for the attachment of the posterior sacroiliac ligaments and for ...
The ischial tuberosity (or tuberosity of the ischium, tuber ischiadicum), also known colloquially as the sit bones or sitz bones, [1] or as a pair the sitting bones, [2] is a large posterior bony protuberance on the superior ramus of the ischium. It marks the lateral boundary of the pelvic outlet.
The deep dorsal sacrococcygeal ligament (ligamentum sacrococcygeum posterius profundum) is a continuation of the posterior longitudinal ligament. [1] A flat band arising inside the sacral canal, posteriorly at the orifice of the fifth sacral segment, it descends to the dorsal surface of the coccyx under its longer fellow described below. [3]
