Front 58

Angle formed by the longitudinal axes of the humerus and forearm

Back 58

Carrying Angle

Front 59

What causing the Carrying Angle

Back 59

Occurs because the distal end of the humerus is not level. Medial side is lower than lateral side. As the ulna and radius rotate about the the trochlea and capitulum of humerus they do not do so in a straight line

Front 60
