What is Scarpa 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.
What 3 structures make up the femoral triangle?
The borders of the femoral triangle are composed of the inguinal ligament superiorly, the adductor longus muscle medially, and the sartorius muscle laterally.
What are the 4 contents of the femoral triangle?
Acronym for the contents of the femoral triangle (lateral to medial) – NAVEL: Nerve, Artery, Vein, Empty space (allows the veins and lymph vessels to distend to accommodate different levels of flow), Lymph nodes.
What is found inside the femoral triangle?
The femoral nerve is the most lateral of the contents in the femoral triangle. It supplies the sartorius, rectus femoris, vastus lateralis, vastus intermedius and vastus medialis muscles in the anterior compartment of the thigh, and the pectineus muscle in the medial compartment.
What action does the femoral triangle perform?
The femoral triangle is a hollow region located in the supero-medial part of the anterior thigh. It appears most prominently with hip flexion, abduction and internal rotation. It is an easily accessible area through which multiple neurovascular structures pass through.
What are the boundaries of femoral triangle?
The femoral triangle has three borders namely:
- Superior (base of triangle): Inguinal ligament.
- Lateral: Medial border of the sartorius muscle.
- Medial: Medial border of the adductor longus.
- Apex: Cross between medial and lateral border.
What is Hunter’s canal?
The Hunter’s canal (subsartorial, adductor canal) is an aponeurotic tunnel in the middle third of the thigh, extending from the apex of the femoral triangle to the opening in the adductor magnus, the adductor hiatus.
What lies in the femoral triangle?
The floor of the femoral triangle is comprised of the adductor longus, pectineus (medially), psoas major and illiacus muscles (laterally). The floor is gutter shaped since all the muscles forming the floor pass to the posterior aspect of the femur.
What is the clinical significance of the triangle of auscultation?
The triangle of auscultation is an important anatomical landmark that allows for better auscultation during the pulmonary examination. [2] When the patient crosses their arms across their chest, the scapula and muscular borders of the triangle of auscultation move in a way to expose the landmark.
