medially by a deep notch, the fovea capitis, in which the accessory and round liga- 
ments are attached. The articular surface is surrounded by a distinct margin. 
The neck (Collum femoris) is most distinct in front and medially. The trochanter 
major is situated laterally; it presents three features. The anterior part or con- 
vexity is situated opposite to the head and rises little above the level of the latter; 
it gives attachment to the deep gluteus muscle, and in the fresh state its lateral 
surface is coated with cartilage, over which a tendon of the middle gluteus passes, 
to be inserted into the crest, which is placed below and behind the convexity. 
The posterior part or summit is separated from the anterior part by a notch; it is 
situated behind the plane of the head and rises to a much greater height. It

furnishes insertion to part of the middle gluteus muscle. Its posterior border is 
continued downward as the trochanteric ridge (Crista trochanterica), which forms 
the lateral wall of the trochanteric fossa (Fossa trochanterica). A number of 
foramina are found in the concave area medial to the convexity. 
The distal extremity (Extremitas distalis) is large in both directions and com- 
prises the trochlea in front and two condyles behind. The trochlea consists of two 
ridges separated by a groove, and forms an extensive surface (Facies patellaris) for 
articulation with the patella. It is very unsymmetrical; the medial ridge is much 
wider, more prominent, and extends up higher than the lateral one, and the two 
converge below. The condyles, medial and lateral (Condylus medialis, lateralis),
