Saphenous Opening

Contents

Introduction

A fascia is a band of connective tissue located beneath the skin, which encloses and separates muscles. There are two main types of fascia: superficial and deep. The deep fascia of the thigh is referred to as the fascia lata.

The fascia lata is split into two layers, which are referred to as the superficial stratum and the deep stratum.

There are three modifications of the fascia lata, one of which is the saphenous opening.

The saphenous opening is an oval aperture located in the fascia lata to allow the passage of the great saphenous vein. This article will discuss the anatomy of this structure followed by any relevant clinical notes on the topic.

Anatomy

The saphenous opening is located inferolateral to the medial aspect of the inguinal ligament and is usually approximately 3.75 cm in length and 2.5 cm wide, but can vary considerably. The centre of the opening is 3-4 cm lateral to the pubic tubercle. The cribriform fascia, a sieve-like membranous layer of cutaneous tissue, covers the opening and is thus pierced by the great saphenous vein. The superficial stratum is located superolateral to the saphenous opening and is continuously attached to the pectin pubis, the lacunar ligament, the inguinal ligament, the anterior superior iliac spine and the iliac crest. The superficial stratum reflects inferolaterally from the pubic tubercle to form the arched falciform margin. This margin forms the superior, inferior and lateral boundaries of the saphenous opening. The deep stratum is located medial to the saphenous opening.
