What is located in the femoral triangle?
The femoral triangle (or Scarpa’s triangle) is an anatomical region of the upper third of the thigh. It is a subfascial space which appears as a triangular depression below the inguinal ligament when the thigh is flexed, abducted and laterally rotated.
Is the saphenous opening in the femoral triangle?
It lies 3–4 cm below and lateral to the pubic tubercle and is about 3 cm long and 1.5 cm wide….
| Saphenous opening | |
|---|---|
| Front of right thigh, showing surface markings for bones, femoral artery and femoral nerve. (Fossa ovalis visible at upper right.) | |
| Details | |
| Identifiers | |
| Latin | hiatus saphenus, fossa ovalis femoris |
Where is the pectineal line?
The pectineal line (pecten pubis) of the pubis is a ridge on the superior ramus of the pubic bone, it passes to the pubic tubercle as a continuation of the arcuate line. The pecten pubis forms part of the pelvic brim. Lying across it are fibers of the pectineal ligament and the proximal origin of the pectineus muscle.
What is spiral line of femur?
The intertrochanteric line (or spiral line of the femur ) is a line located on the anterior side of the proximal end of the femur. Intertrochanteric line. Right hip-joint from the front.
Where is the linea aspera of the femur?
The linea aspera is the rough, longitudinal, irregular crest on the posterior surface of the shaft of the femur. It is formed by the joining of lateral and medial lips, which may be separated by up to 10 mm [1]. It is divided distally into medial and lateral supracondylar ridges.
What is Iliopubic eminence?
Medial to the anterior inferior iliac spine is a broad, shallow groove, over which the iliacus and psoas major muscles pass. This groove is bounded medially by an eminence, the iliopubic eminence (or iliopectineal eminence), which marks the point of union of the ilium and pubis.
What surface of femur is Linea Intertrochanterica?
The intertrochanteric line (or spiral line of the femur ) is a line located on the anterior side of the proximal end of the femur.
What is the linea aspera called?
The linea aspera (Latin: rough line) is a ridge of roughened surface on the posterior surface of the shaft of the femur. It is the site of attachments of muscles and the intermuscular septum.
Which muscles attach to linea aspera?
Attachments
- pectineus.
- adductor minimus.
- adductor brevis.
- adductor longus.
- adductor magnus (hamstrings part)
What is the iliopectineal line?
The iliopectineal, or iliopubic, line is the radiographic landmark for the anterior column. It begins at the sciatic notch and travels along the superior pubic ramus to the symphysis pubis. The ilioischial line demarcates the posterior column.
Where is Iliopectineal eminence found?
An eminence on the upper aspect of the pubic bone above the acetabulum, marking the junction of the bone with the ilium.
Where is the quadrate tubercle?
femur
The quadrate tubercle is a small tubercle found upon the upper part of the femur, that serves as a point of insertion of the quadratus femoris along with the intertrochanteric crest and the linea quadrata.
Where is the patellar surface?
Description. The front part of the lower end of femur is named the patellar surface and articulates with the patella; it presents a median groove which extends downward to the intercondyloid fossa and two convexities, the lateral of which is broader, more prominent, and extends farther upward than the medial.
What is the surface anatomy of the femoral triangle?
Fig 1.0 – Surface anatomy of the femoral triangle. As this area is a triangle, it has three borders: Superior border – Formed by the inguinal ligament, a ligament that runs from the anterior superior iliac spine to the pubic tubercle. Lateral border – Formed by the medial border of the sartorius muscle.
How do you remember the borders of the femoral triangle?
The borders of the femoral triangle can be remembered using the word SAIL, as demonstrated in the table above. As well as these boundaries, the femoral triangle also has a floor and a roof. The floor is comprised of four muscles that can be easily remembered by using the mnemonic APPI ( adductor longus, pectineus, psoas major and illiacus muscles).
What muscles make up the femoral triangle?
Anteriorly, the roof of the femoral triangle is formed by the fascia lata. Posteriorly, the base of the femoral triangle is formed by the pectineus, iliopsoas and adductor longus muscles.
What structures are located in the femoral sheath?
Each of the structures located in the femoral sheath is individually enclosed in its own compartment. The most medial compartment is the femoral canal, which contains the lymphatic vessels. The proximal opening of the femoral canal is the femoral ring.
