As the pubis extends it is still separated by the cellular capsule from the femur. These are separated from the ilio-femoral set by an interval, apparent on the bone and marking the limit of the secondarily added pubic area of articular surface see Fig. The lower aspect of the tuber ischii, below the facets for the hamstring muscles, shows two sloping surfaces, of which one looks outwards and gives origin to fibres of Adductor magnus ischio-condylar portionwhile the other looks inwards D and is covered by fibro-fatty tissue which is continuous round the great sacro-sciatic ligament with that of the ischio-rectal fossa : in this tissue is a badly-defined bursa which lies under the tuberosity in sitting, the hamstrings and Adductor moving to the outer side of the prominence when the limbs are bent for that purpose. The front of the eminence is roughened by fibres belonging to the pubofemoral group of ligaments. The articular surface of the acetabulum surrounds on three sides the non-articular cotyloid or acetabular fossa, which contains the fatty tissue of the " Haversian gland," and opens below at the cotyloid notch. But as a matter of fact the triradiate cartilage that separates these elements, almost till puberty, develops a variable number of small ossifying centres in the floor of the acetabulum : these may fuse to form a small separate bone, the os acctabuli, but in any case there is ultimate junction of the various parts, and the acetabular centres are usually described as forming a part of the pubic element.

A key reference point in the acetabulum is the cotyloid fossa—that is, the central nonarticular aspect of the acetabulum below the acetabular roof (Fig. 1). Orthopedics.

The position of the sacrum and great ligament is indicated, with the origin of the muscle from it.
Later it breaks through this capsule and becomes articular, the synovial cavity extending over it from the Ilium. The front of the eminence is roughened by fibres belonging to the pubofemoral group of ligaments.
Later it breaks through this capsule and becomes articular, the synovial cavity extending over it from the Ilium. It has already been said that the three main elements of the bone are all represented in the acetabulum.

The acetabular fossa is a fossa located at the centre of the acetabulum. It is occupied by the ligament of head of femur. In contrast to the thick and smooth.
Orthopedics | Standard hip arthroscopy emphasizes access to disease within for removal of space-occupying lesions within the cotyloid fossa.
As the pubis extends it is still separated by the cellular capsule from the femur. The fibrous basis of the ligamentum teres is attached to the ischial and iliac parts of the cotyloid fossa and to the transverse ligament : its synovial covering is attached to the whole margin of the fossa and the whole length of the transverse ligament below, covering the fossa but lying free on its surface.
In the human embryo the Ischium and Ilium alone are concerned in the articulation with the femur and the capsule is attached round their ventral margin : the pubic cartilage is extracapsular.
The Acetabular Region
In the adult the pubic articular surface is still more or less distinct from the iliac surface, and the same distinction is usually marked on the rim by a shallow notch ; here the communication may take place of the joint with the sub-psoas bursa, between the Iliac and pubic parts of the capsule.

|There is only a slight capsular attachment behind the acetabulum, for there are no true transverse fibres on the back of the joint, and only a few of the inner marginal fibres of the circular group run to the bone in this region : a group of these below reach the upper ramus of ischium as the " ischio-capsular band".
Some of the fibres of the great sciatic ligament run on to the surface of the bone round x, and give origin here to part of G. It has already been said that the three main elements of the bone are all represented in the acetabulum.
The fibrous basis of the ligamentum teres is attached to the ischial and iliac parts of the cotyloid fossa and to the transverse ligament : its synovial covering is attached to the whole margin of the fossa and the whole length of the transverse ligament below, covering the fossa but lying free on its surface.
Above this notch is the large rough area for the A-shaped Iho-femoral band, spreading on to the lower half or more of the anterior inferior spineand below and internal to it is the area for the pubo-femoral band which extends inward along the front edge of the upper pubic ramus, overhanging the issuing obturator nerve.
