THE HIP-JOINT 



327 



The arteries supplying the joint are derived from the obturator, sciatic, internal circumflex, 

 and gluteal. 



The nerves are articular branches from the sacral plexus, great sciatic, obturator, accessory 

 obturator, and a filament from the branch of the femoral (anterior crural) supplying the 

 Rectus femoris. 



Bursse. Numerous bursje exist in the neighborhood of the hip-joint. Some anatomists have 

 counted twenty-one (Synnestredt). The chief ones are: (1) The iliopectineal bursa (bursa ilio- 

 peclinea) (Fig. 265), between the Iliopsoas tendon and the capsule of the joint. This bursa 

 often communicates with the hip-joint. (2) The subtendinous iliac bursa (bursatiliaca ttub- 

 fr inlinca), between the tendon of the Psoas and Iliacus and the lesser trochanter. (3) The ischio-

gluteal bursa (bursa ischiadica m. ylutaei maximi), between the Gluteus maximus muscle and 

 the tuberosity of the ischium (not constant). (4) The bursa of the greater trochanter (bursa 

 Irochanterica m. ylutaei maximi), between the greater trochanter and the Gluteus maximus muscle 

 near the muscular insertion. (5) Two or three gluteofemoral bursae (bursae ylutaeofemorales) 

 below. (6) The obturator bursa (bursa m. obturafarii interni), between the margin of the great 

 sacrosciatic notch and the tendon of the Obturator internus muscle. (7) The subcutaneous 

 trochanteric bursa (bursa trochanterica subcutaned), between the cutaneous surface and the great 

 trochanter. Besides these there is a bursa between the greater trochanter and the anterior part 

 of the Gluteus medius; between the greater trochanter and the posterior part of the Gluteus 

 medius; between the greater trochanter and the Gluteus minimus; beneath the Pyriformi.s
