. A treatise on dislocations and fractures of the joints. everywhere inclose contact with that of the acetabulum, is retained in the cavity bya considerable amount of atmospheric pressure; so that when all theligaments are completely severed, it still requires some little force todislodge it. Ligaments.—The principal liga-ments of this joint are the capsular,and the ligamentum teres, besidesthe fibro-cartilaginous rim or coty- -loid ligament of which we havejust spoken. The capsular ligament arisesfrom the whole circumference ofthe acetabulum, and, passing out-wards, is inserted into the neck ofthe femur. In front it is insertedinto that line which extends fromthe greater to the lesser trochanter;posteriorly, it does not extend sofar outwards, but is inserted intothe neck of the bone about midwaybetween its head and the trochan-ter major; at its insertion it is incorporated with the periosteum. It isthickest and strongest at its upper and anterior part, where it is furtherstrengthened by the accessory or ilio femoral ligament, which passes. ANATOMY OF THE HIP-JOINT. 29 across the front of the joint from the anterior inferior spinous processof the ilium to near the lesser trochanter. But in its inferior part itsfibres are weaker, and often so much separated as to allow of thepassage of blood vessels between them. The ligamentum teres, or interarticular ligament, is somewhat tri-angular in figure, and is attached by its apex to a depression on thehead of the femur, and by itsbase to the notch of the aceta-bulum. Its base is bifurcated,and divided into two flattenedbands, which are continuous,with the fibrous part of thecotyloid ligament. The cotyloid ligament, as wehave already said, completelysurrounds the edge of the ace-tabulum, and passes over thenotch on it* inner side, so as toconvert it into a foramen,through which pass the vesselsthat supply the synovial mem-brane. It is prismatic in shape,being attached by a broad baseto the edge of the acetabulum, while it
