Current Imaging Concepts in Shoulder and Hip Arthroplasty.

Overview

Primary joint replacements are increasingly being performed, likely owing to our aging population and improved techniques. Advances have been made in shoulder joint replacements including development of cuff tear arthroplasty hemiarthroplasty, improvements to reverse total shoulder arthroplasty designs, and more detailed preoperative imaging. The importance of spinopelvic kinematics has been brought to light in hip joint replacements. Appropriate preoperative measurement and subsequent compensation for the malalignment are critical.
