Articulation of the phalanges. 1. Hljy-Joint.—The articulation of the head of the femur with the acetabulum constitutes an enarthrosis, or ball-and-socket joint. The articular surfaces are the cup-shaped cavity of the acetabulum and the rounded head of the femur; the ligaments are Jive in number, viz :— Capsular, Teres, Ilio-femoral, Cotyloid, Transverse. The capsular ligament is a strong ligamentous capsule, em- bracing the acetabulum superiorly, and inferiorly the neck of the femur, and connecting the two bones firmly together. It is much thicker upon the upper part of the joint, where more resistance is required, than upon the under part, and extends further upon the neck of the femur on the anterior and superior than on the posterior and inferior side, being attached to the inter-trochan- teric line in front, to the base of the great trochanter above, and to the middle of the neck of the femur behind. The ilio-femoral ligament is an accessory and radiating band, which descends obliquely from the anterior inferior sjiinous pro- cess of the ilium to the anterior inter-trochanteric line, and strengthens the anterior portion of the capsular ligament. The ligamentum teres, triangular in shape, is attached, by a round apex, to the depression just below the middle of the head of the femur, and by its base, which divides into two fasciculi, into the borders of the notch of the acetabulum. It is formed by a fasciculus of fibres, of variable size, surrounded by synovial membrane ; sometimes the synovial membrane alone exists, or the ligament is wholly absent. The cotyloid ligament is a prismoid cord of fibro-cartilage, attached around the margin of the acetabulum, and serving to deepen that cavity and protect its edges. It is much thicker upon the upper and posterior border of the acetabulum than in front, and consists of fil)res which arise from the whole circum- ference of the brim, and interlace with each other at acute angles. It is directed inwards towards the acetabulum. The transverse ligament is a strong fasciculus of ligamentous fibres, continuous with the cotyloid ligament, and extended across the notch of the acetabulum. It converts the notch into a fora-
