Kinematics and biomechanics in normal and replacement elbow

The biomechanics of normal elbow is of primary importance because its comprehension can help the understanding of the functionality of the whole upper limb. The elbow represents a connecting point between the arm and the forearm contributing to modify the relationship between these segments to correctly position the hand in the three-dimensional space. In the following chapter, we will discuss which are the kinematic requirements needed to perform activities of daily living, as well as the impact of muscular actions and external forces on elbow. The final part of the chapter will focus on the role of biomechanics in elbow arthroplasty surgery and its implication in real-life settings.
