    The results of total elbow replacement (TER) in 45 elbows of 38 patients with rheumatoid arthritis were compared with results of radial head excision with synovectomy (RHES) in 45 age-matched patients treated in the same unit. The groups were similar with respect to duration of disease and preoperative clinical status, although pain was of longer duration and slightly more severe in the TER group. Failure was defined as the onset of moderate or severe pain after surgery or revision surgery for any reason. Reduction in pain was greater after TER than after RHES (P < .05). Recurrence of pain was common after RHES but was not seen after TER. Movement increased by a similar amount in each group. Complications were more frequent and more serious after TER (4 dislocations, 4 ulnar nerve dysfunctions, 1 significant wound breakdown) than after RHES (2 ulnar nerve dysfunctions, 1 transient wound discharge). Complications after TER were most common in patients who had previous RHES. On survival analysis, TER results were better than RHES results in each successive year. Cumulative survival rates at 10 years were 85% for TER and 69% for RHES, but the difference in rates was not statistically significant. In the medium term, TER relieves pain more reliably than RHES and its use is justified despite the greater risk of complications. In view of the paucity of long-term results for TER, RHES may retain a role in younger patients or in those whose symptoms are related mainly to the radiohumeral joint

    Synovectomy of the elbow and radial head excision in rheumatoid arthritis. Predictive factors and long-term outcome.

    We carried out a survival analysis of elbow synovectomy (ES) and excision of the radial head (RHE) performed on 171 rheumatoid elbows. The failure criteria were revision surgery (performed or desired) and/or the presence of significant or severe pain. The cumulative survival was 81% at one year which thereafter decreased by an average of 2.6% per year. The strongest predictor for success was a low preoperative range of supination-pronation when corresponding survival curves were compared. A low range of flexion-extension also predicted failure. Combining both factors gave better prediction (failure: 6.3% v 67%), but a long duration of elbow symptoms before surgery predicted failure (72%, p = 0.04). At review, there was a mean gain of 50 degrees in supination-pronation and 11 degrees in flexion-extension; both correlated with success. Failure correlated with recurrence of synovitis, elbow instability, ulnar neuropathy, poor general mobility and poor upper-limb function. The last was independently affected by the severity of RA in the ipsilateral shoulder. Our findings show that although the short-term result of ES and RHE in rheumatoid arthritis is good, the long-term outcome is poor except in a subgroup with more than 50% limitation of forearm rotation
