Total elbow arthroplasty for posttraumatic arthrosis.

Total elbow arthroplasty can be effective in treating acute injuries and posttraumatic conditions of the elbow, although typically it is considered a salvage procedure. The ideal prosthetic implant appears to be linked and semiconstrained, with an anterior flange to resist posterior and rotatory forces. The ability to fix the stem without condyle preservation is important in treating a posttraumatic condition. The results of total elbow arthroplasty can deteriorate over time because of periprosthetic fracture, implant fracture, bushing wear, or other mechanical failure. The rate of aseptic loosening is less than 10% after 10 years, which is lower than had been anticipated. Elbow replacement can be extremely effective for a properly selected patient with posttraumatic arthrosis. However, approximately 25% of patients have a complication.
