The earliest distal humeral hemiarthroplasty (EHA) implants, which date back to the late 1940s, were performed in patients with severe elbow joint injuries as an alternative to arthrodesis. After some clinical reports and case studies with a short follow-up, published in the 1990s, a new “anatomically convertible” EHA model was introduced in 2005 and became a common surgical option to treat complex elbow fractures and their sequelae.
