The Hip Joint and Pelvic Gateways
The Hip Joint is a typical synovial joint that is a •Ball and socket joint•It may also be described as a multi-axial, spheroidal joint that permits an extensive range of movement
The Hip Joint is formed by an articulation between the •Head of the Femur•Acetabulum of the Hip Bone
The Acetabulum is a deep cup-shaped bony depression on the lateral aspect of the hip bone and is formed by the union of the three constituent bony parts• Ilium• Pubis• Ischium

Acetabular Labrum
Is a rim of fibro-cartilaginous tissue that is attached to the periphery of the Acetabulum. It helps to deepen the cup thereby improving joint stability.

Hip Joint Capsule
The capsule of the hip joint is reinforced by 3 strong ligaments that are thickenings or condensations of the capsule on the anterior, inferomedial and posterior aspects
Ligaments of the Hip Joint
Ligaments of the Hip Joint
Iliofemoral Ligament
Is the strongest of the hip joint ligaments
An inverted Y-shaped ligament

Transverse Acetabular Ligament
Is continuous peripherally with the labrum

Pelvic Gateways
There are two major pelvic gateways that transmit vessels from the pelvis to the lower limb •Myopectineal Orifice•Greater Sciatic Foramen

Inferior Aspect Pelvis
Myopectineal Orifice
The Inguinal Ligament is the continuation of the lower edge of the
External Oblique Aponeurosis
Inguinal Ligament
It forms the upper boundary
of the Myopectineal Orifice
Pubis
The inferior boundary of the Myopectineal Orifice is the superior ramus of the pubis
and adjacent Ilium

The Femoral Nerve, Artery and Vein pass
through the Myopectineal Orifice
from the Iliac Fossa to enter the Lower Limb
