extremity represented by the distribution of the internal 

 saphenous vein (internal, anterior, and posterior area of 

 lower extremity). 



The Prepatellar Bursa 



Will be found over the patella, between it and the deep 

 fascia. A vertical incision will open into the bursa. 



DISSECTION. 



Remove all of the superficial fascia, leaving the vessels and nerves lying 

 upon the fascia lata. 



Recognize the deep layer of the superficial fascia and its attachments, 

 then remove it carefully and expose the saphenous opening, and vein passing 

 through it. Save the denser, curved outer band and the thinner inner por- 

 tion of the fascia bounding the saphenous opening. 



The Fascia Lata, Anterior Portion. Figs. 115, 116. 



This is a strong tube of membrane enclosing the thigh. 

 Attached below to the bony points about the knee con- 

 dyles of femur, patella, tuberosities of tibia, head of the 

 fibula. Above, anteriorly, Poupart's ligament, spine, crest, 

 and front of the pubes (iliac portion). The pubic portion 

 is under the iliac portion and is attached to the iliopectineal 

 line, and externally blends with the iliac fascia from the 

 pelvis. (See page 525.) Internally, to the rami of the 

 pubes and ischium. Posteriorly, see page 600. 



(a) Intermuscular Septa. A strong one is found ex- 

 ternally between the vastus and the biceps muscles attached 

 to the external lip of the linea aspera. A less distinct 

 septum is found in front of the adductor muscles, and a 

 third one behind them. From the under surface of the fascia 

 lata there also extend off processes to enclose all the 

 muscles of the thigh in separate compartments. 



(b) The Iliotibial Band. This is a reinforcement of the 

 transverse fibres of the fascia lata along the outer side of
