behind it, is a hollow, oval pit (fovea capitis femoris) for the attachment of the 

 ligamentum teres. Piercing the floor of this depression! are seen several foramina 



through which - vessels 

 pass to supply the head 

 of the bone ; the proximal 

 epiphysis thus having a 

 double blood supply, viz., 

 from the neck distally,and 

 through the medium of the 

 ligamentum teres proxi- 

 mally. The circumfer- 

 ence of the head forms 

 a lip with a wavy outline, 

 more prominent above 

 and behind than in front. 

 The head is supported 

 by a stout compressed 

 bar of bone, the collum 

 femoris (neck), which 

 forms with the proxi- 

 mal end of the body 

 an angle of about 125 

 degrees, and is directed 

 proximally, medially, and 

 a little forwards. Its 

 vertical width exceeds its 

 antero-posterior thickness. 

 Constricted about its 

 middle, it expands medi- 

 ally to support the head, 

 whilst laterally, where it 

 joins the shaft, its vertical 

 diameter is much in- 

 creased. Anteriorly it is 

 clearly defined from the 

 shaft by a rough ridge 

 which commences above 

 on a prominence, some- 

 times called the tubercle 

 of the femur, and passes 

 obliquely downwards and 

 medially. This constitutes 

 the upper part of the 

 linea intertrochanterica 

 (intertrochantericline), and 

 serves for the attachment 

 of the ilio- femoral liga- 

 ment of the hip -joint. 

 Posteriorly, where the neck 

 unites with the body, 

 there is a full rounded 

 ridge passing from the 

 trochanter major proxi- 

 mally to the trochanter 

 minor distally; this is 

 the crista intertrochan- 

 terica (intertrochanteric crest). A little proximal to the middle of this ridge there is 

 usually a fulness which serves to indicate the proximal limit of attachment of the 

 quadratus femoris muscle, and is called the tubercle for the quadratus. Laterally the
