THE HIP JOINT
• eSkeletons.com
• Skeletal System PSU
The Pelvis
 The Pelvic bone is
divided into THREE
SECTIONS



Ilium
Pubis
Ischium
Pelvis
The Pelvis - ILIUM
 Upper 2/5ths
 1. Iliac crest
 2. Anterior spine


a. superior
b. inferior
 3. Sciatic notch
The Pelvis - ILIUM
 Iliac crest
The Pelvis – ILIUM (Lateral View)
Sciatic notch
The Pelvis - ISCHIUM
Posterior and lower 2/5ths
1. Acetabulum
The Pelvis - ISCHIUM
The Pelvis - ISCHIUM
 2. Ischial tuberosity
The Pelvis - PUBIS
Pubic synthesis/crest
II. The Femur
 A. Head
 B. Neck
 C. Greater Trochanter
 D. Lesser Trochanter
 E. Linea Aspera -
vertical ridge on the
posterior surface
 F. Lateral Condyle
 G. Medial Condyle
