PRACTICAL ANATOMY. 



Two Important Surgical Areas. Scarpas triangle and Hunter s canal. 



Scarpa's triangle is located on the upper anterior one-third of the thigh. It 

 is divided into an inner and an outer part by the femoral vessels, which bisect the 

 space vertically. It is of surgical importance for the following reasons : 



1. Inguinal and femoral herniae are seen here. 



2. Varicocele, dilatation of scrotal or spermatic veins. 



3. Removal of inguinal lymphatic glands may become necessary. 



4. Fracture of the femur and dislocations of its head.

5. Burrowing of pus from regions above may point here. 



6. Bloodless amputation at the hip involves this region. 



7. Injuries to the vessels and nerves in the space may occur.
