We report the effectiveness of revision of total
elbow replacement by re-cementing. Between 1982 and 2004, 53 elbows
in 52 patients were treated with re-cementing of a total elbow replacement
into part or all of the existing cement mantle or into the debrided
host-bone interface, without the use of structural bone augmentation
or a custom prosthesis. The original implant revision was still
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.
We have reviewed 36 of 39 consecutive patients with an average age of 68 years who had semiconstrained elbow replacement for distal humeral nonunion at an average follow-up of 50.4 months (24 to 127). Of these, 31 (86%) had satisfactory results, three (8%) had fair, and two (6%) had poor results; 32 patients (88%) had moderate or severe pain before and 91% had no or only mild discomfort after the procedure. Motion had improved from a mean arc of 29 degrees to 103 degrees before operation to 16 degrees to 127 degrees after surgery. All five flail extremities were stable at last assessment. There were seven complications (18%): two patients had deep infection, two had particulate synovitis, two had ulnar neuropathy and one had worn polyethylene bushes. Five of these seven, excluding the two with transient nueropathy, required reoperation (13%). Joint replacement arthroplasty can be a safe and reliable treatment for this difficult clinical condition, seen most commonly in elderly patients. This is a significant advance, since repeated osteosynthesis has been shown to be ineffective in most patients.
Fifty-three of 55 consecutive elbow replacements for post-traumatic arthritis were followed for a minimum of two years (mean 6.3, range 2 to 14.4). The patients presented difficult management problems, having undergone an average of two previous operations per joint; 22 joints had suffered prior complications; 18 had less than 50 degrees of flexion and six were flail. One of three versions of the Coonrad prosthesis was employed in all. During the follow-up period, 10 patients underwent 14 revision procedures for aseptic loosening; 38 elbows are currently without progressive radiolucent lines. In two patients an elbow had to be resected, one for deep infection and the other for bone resorption following a foreign-body reaction to titanium. The current design of the Coonrad prosthesis offers a reliable option for the treatment of post-traumatic arthritis but should be used only in carefully selected patients over the age of 60 years.
