Replacement radial head surgery is often recommended for complex elbow fractures that cannot heal properly with casting or physical therapy alone. The radial head plays a vital role in elbow stability and arm rotation, making timely treatment essential. Without proper intervention, patients may develop chronic pain, stiffness, and limited function. In severe cases, elbow joint replacement may also be necessary to restore full joint mechanics. With expert surgical care and a guided elbow surgery recovery plan, most patients experience significant pain relief and improved daily function.
