Current concepts in elbow kinematics and biomechanics

Purpose of review: Recent advances in the diagnosis and treatment of elbow disorders require that orthopedists develop a better understanding of the elbow. This paper reviews the current literature on elbow kinematics and biomechanics. Recent findings: This review covers elbow anatomy and how this affects its stability; elbow kinematics and biomechanics in sports, including pediatric athletes; and a theoretical section on basic kinematics. Summary: Current literature on the osseous and ligamentous stabilizers of the elbow will help surgeons better treat elbow instability that occurs through trauma and sports. Current understanding of the biomechanics of the elbow in both adult and pediatric athletes will hopefully help prevent and treat injuries in athletes. Finally, as understanding of elbow kinematics becomes more sophisticated through use of computer models, designs for elbow arthroplasty will hopefully improve.
