We examined the effects of previous resection of the radial head and synovectomy on the outcome of subsequent total elbow arthroplasty in patients with rheumatoid arthritis.Fifteen elbows with a history of resection and synovectomy were compared with a control group of patients who had elbow arthroplasty with an implant of the same design. The mean age in both groups was 63 years. In the study group, resection of the radial head and synovectomy had been undertaken at a mean of 8.9 years before arthroplasty. The mean radiological follow-up for the 13 available patients in the study group was 5.89 years (0.3 to 11.0) and in the control group was 6.6 years (2.2 to 12.6). There were no revisions in either group. The mean Mayo elbow performance score improved from 29 to 96 in the study group, with similar improvement in the control group (28 to 87). The study group had excellent results in 13 elbows and good results in two. The control group had excellent results in seven and good results in six.Our experience indicates that previous resection of the radial head and synovectomy are not associated with an increased rate of revision following subsequent arthroplasty of the elbow. However, there was a higher rate of complication in the study group compared with the control group.The challenge for orthopaedic surgeons treating patients with rheumatoid arthritis of the elbow is to achieve a painless, stable, and functional elbow. The initial management consists of medical treatment to control synovitis. If this fails, various surgical options can be considered. Several reports have shown good results following resection of the radial head and synovectomy. [1][2][3][4][5][6][7][8][9][10][11][12][13] The results of total elbow arthroplasty in these patients have also been good. [14][15][16][17][18][19][20][21] Data are limited on the effect of a previous resection of the radial head and synovectomy on subsequent total elbow arthroplasty. 22 Our aim, therefore, was to compare the outcome of total elbow arthroplasty with and without a history of previous surgery.
Patients and MethodsWe used the joint replacement computer database at our institution to identify those patients with rheumatoid arthritis who had been treated by total elbow arthroplasty (Coonrad Morrey; Zimmer, Warsaw, Indiana) and who had a previous excision of the radial head and synovectomy. To detect more accurately the effect, if any, of the previous surgery, a control group was identified. This was developed from a database of patients with rheumatoid arthritis who had been treated using the same prosthesis during the same period of time. None had a previous resection of the radial head and synovectomy and they were matched by gender, side of involvement, and age. There was a minimum follow-up of two years for both groups. We retrospectively reviewed the records and radiographs of both groups. Additional contact was attempted in all patients. The Mayo elbow performance score (MEPS) was used to assess pain, movement, stability, and daily function as has been ...
