Abstract
Elbow replacement arthroplasty has become a standard surgical treatment for a variety
of diseases of the elbow. First popularized for the treatment of late-stage rheumatoid
arthritis and other debilitating forms of joint disease, the current indications have
expanded to include primary treatment of elbow trauma. The most commonly used total
elbow replacements are linked semiconstrained chromium-molybdenum alloy or titanium
alloy prostheses with polyethylene bearing surfaces. These are inserted after resection
of the ulnotrochlear joint and typically cemented in place; the radial head is often
sacrificed. Modular metal components or massive osteoarticular allografts may be used
when there is extensive bone deficiency. Metal radial head replacements are increasing
being used for primary fracture treatment and in posttraumatic elbow reconstructive
surgery. Long-term outcomes for total elbow replacement are similar to those of other
joints, with 10-year survivals of ∼90%. Complications specific to elbow implants include
infection, aseptic loosening, prosthetic failure, and periprosthetic fracture.
