Femoral triangle. The femoral triangle (or Scarpa's triangle) is an anatomical region of the upper inner thigh. It is a subfascial space which appears as a triangular depression inferior to the inguinal ligament when the thigh is flexed, abducted and laterally rotated. Contents.
The femur is the bone of the upper leg. The proximal end of the femur connects to the hip joint. It is marked by a spherical ball, called the femoral head, that fits into the socket of the hip joint, the acetabulum. The head is connected to the shaft of the femur by an elongated segment of bone, called the femoral neck.Lateral to the neck, a large projection juts proximally off the top of the bone, called the greater trochanter.he head of the femur connects to the hip joint, so it is toward the middle of the body. Using anatomical terminology, itâs medial and proximal. The greater trochanter is on the lateral side of the bone, away from the middle of the body. The front side of the femur (called the anterior side) is fairly smooth.
