Topographic · 267. Anterior region of thigh.

Covers the boundaries of the thigh and its division into anterior, posterior and medial compartments by the fascia lata, then the anterior compartment in detail: skin, superficial fascia, cutaneous nerve supply, the saphenous opening, deep fascia and superficial arteries. It also describes the femoral triangle and iliopectineal fossa with their boundaries and contents, and the adductor canal with its boundaries and contents, plus a short clinical note on the femoral triangle.

Introduction

(for both gluteal & thigh regions)

Obturator Canal:

The obturator canal is formed in the area of the obturator groove where the obtura-tor foramen is not fully covered by the obturator membrane. The obturator nerve and vessels pass through this canal.

Anterior view of right half of the pelvis

  1. 1 Obturator canal

Content:

  1. 1.1 Obturator nerve
  2. 1.2 Obturatory artery and veins

Boundaries :

  1. 1. Upper Boundary:
  • Plica inguinalis (inguinal fold): Separates the thigh from the abdominal wall.
  • Sulcus glutealis: Separates the thigh from the gluteal region.
  1. 2. Lower Boundary:
  • Circular line: Approximately two fingers' width proximal to the upper border of the patella.

Divisions :

  • Fascia lata (deep fascia), completely envelops the muscles of thigh.
  • Gives 3 intermuscular septa penetrate btw. muscle groups, & divide the thigh into:
  1. 1. Ant. Region
  2. 2. Post. Region
  3. 3. Medial. Region.
  4. 1 Anterior compartment of thigh (compartimentum femoris anterius)
  • contains the anterior group of thigh muscles
  1. 1.1 Femoral nerve – branches in the iliopectineal fossa
  2. 1.1.1 Saphenous nerve – the terminal branch of the femoral nerve
  • – travels with the femoral atery and vein through the adductor canal
  • – reaches the subcutaneous tissue after passing through the vasto-adductor membrane
  1. 1.2 Femoral artery – - gives off most of its branches within the iliopectineal fossa
  • – travels through the adductor canal and adductor hiatus to reach the popliteal fossa
  1. 1.2.1 Profunda femoris artery (deep artery of thigh)
  • – runs between the muscles of the medial thigh
  1. 1.3 Femoral vein – the continuation of the popliteal vein after passing through the adductor hiatus
  • – passes through the adductor canal
  • – joins the profunda femoris vein in the iliopectineal fossa to form the common femoral vein, which receives the great saphenous vein
  1. 1.3.1 Great saphenous vein – runs in the subcutaneous tissue on the medial side of the thigh
  2. 2 Posterior compartment of thigh (compartimentum femoris posterius)
  • contains the posterior group of thigh muscles
  1. 2.1 Sciatic nerve – courses between the posterior thigh muscles to reach the popliteal fossa, where it bifurcates (in most cases)
  2. 2.2 Posterior cutaneous nerve of thigh – runs in the subcutaneous tissue (in the distal part it runs with the cranial extension of the small saphenous vein)
  3. 3 Medial compartment of thigh (compartimentum femoris mediale)
  • contains the medial group of thigh muscles
  1. 3.1 Obturator nerve, artery and veins – supply the proximal part of the medial side of the thigh
