1. The Hip Joint and Pelvic
Gateways

2. 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

3. The Hip Joint is formed by an articulation between the
•Head of the Femur
•Acetabulum of the Hip Bone

4. 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

5. 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.

the Acetabulum. It helps to
deepen the cup thereby improving
joint stability.

11. 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

12. Ligaments of the Hip Joint
Iliofemoral Ligament
Is the strongest of the hip joint

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

21. 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

22. Pubis
The inferior boundary of the
Myopectineal Orifice is the
superior ramus of the pubis
and adjacent Ilium
