TAMPA, Fla. — Revision radial head arthroplasty was associated with “substantial improvements” in pain relief and motion with good or excellent Mayo Elbow Performance Scores in 54% of elbows, according to presented results.
Thomas H. Rogers, MD, from the department of orthopedic surgery at Mayo Clinic in Rochester, New York, presented his findings on revision radial head arthroplasty at the American Shoulder and Elbow Surgeons Annual Meeting.
Using the total joint registry database of the Mayo Clinic, Rogers and colleagues analyzed data on 41 patients who underwent revision radial head arthroplasty between 2001 and 2019. According to the abstract, the most common indications for revision were painful loosening (n =19) and radius overlengthening, also called “joint overstuffing,” (n = 10). Outcome measures included VAS pain scores, range of motion (ROM) and the Mayo Elbow Performance Score (MEPS).
At the most recent follow-up, mean VAS pain score was 3, ROM improved from 95 to 120 and mean MEPS was 70 – all “substantial improvements,” according to Rogers.
“[It is] important to note here that only 54% of the 41 elbows in our study had an excellent or good MEPS score,” he added.
The overall complication rate was 35%, with 32% of patients requiring reoperation. Estimated implant survivorship was 97% and 93% at 2 years and 5 years, respectively; however estimated survivorship decreased to 71% at 10 years. Rogers also noted the use of a cemented short stem as the revision implant resulted in a higher rate of stem failure compared with any other stem type.
“Revision should be performed with a long-stemmed implant, and capitellar and/or lateral trochlear ridge wear led to progression of arthritis,” Rogers added.
