Applied anatomy & Biomechanics of the hip joint

ANATOMIC CONSIDERATIONS

A ball and socket synovial joint

Muscles:

Muscle Table

Acetabulum

  • Cavity faces obliquely forward, outward and downward

  • A line through the circumference is at 40 degrees opening posteriorly from the sagittal plane and at 60 degrees from the transverse (horizontal) plane

Femoral head

  • Forms 2/3 of a sphere

  • Articular surface is thicker on the mediocentral part and thinnest on the periphery

  • The Joint reaction force usually acts on the superior quadrant

Blood supply of femoral head

Three sources

  1. Medial circumflex femoral artery,  most important supply, a branch of the profunda femoris artery

  2. Lateral circumflex artery, supplies the inferior portion, a branch of the profunda femoris

  3. Artery of the ligamentum teres, minor blood supply in the adult, a posterior branch of the obtuator artery

Femoral neck

  • The Neck shaft angle  mostly is 125 degrees, but varies between 90 and 135 degrees. >125 degrees = coxa valga. < 125 degrees = coxa vara

  •  The angle of anteversion is approx 12 degrees in adults
