The radial head size in relation to osseous landmarks of the forearm

Purpose Radial head fractures are regularly treated with radial head arthroplasty. To prevent limited motion or pain, the implant’s size should match its normal anatomy. Preoperative estimation of the radial head size helps in finding the correct head component. The aim of this study was to measure bony landmarks in proximity to the radial head to estimate the required size of a prosthesis preoperatively.
