What is the biomechanics of the elbow joint?
INTRODUCTION • The joints and muscles of the elbow complex are designed to serve the hand.They provide mobility for the hand in space by shortening and lengthening the upper extremity. • Rotation at the elbow complex provides additional mobility for the hand. • The elbow complex structures also provide stability for skilled(or)forceful movements of the hand when performing activities with tools or implements. • Many of the 16muscles that cross the elbow complex also act at either the wrist or shoulder, and therefore the wrist and shoulder are linked with the elbow in enhancing (increase)of the hand. INTRODUCTION ABOUT - HUMERO-RADIAL and HUMERO-ULNAR JOINT • Type- Synovial joint (diarthrodial). • Variety- Modified(or)Loose Hinge joint. • Why it is called as modified or loose hinge joint? -> As light bit of axial rotation and side-to-side motion of the ulna occurs during Flexion and Extension. -> So it is not pure Hinge joint. • Uniaxial- One degree of freedom p...
