Postoperative results and complications of total elbow arthroplasty in patients with rheumatoid arthritis: three types of nonconstrained arthroplasty

Postoperative results and complications of total elbow arthroplasty (TEA) conducted for rheumatoid arthritis (RA) patients at our institute were studied. Primary TEAs were performed in 72 patients. The mean follow-up period was 3.5 years. Three types of prostheses were implanted: JACE prosthesis in 34 elbows, STABLE prosthesis in 13 elbows, and KUDO prosthesis (type 5) in 32 elbows. The outcome was evaluated by the change in the range of motion and the Japanese Orthopaedic Association functional evaluation score for the elbow joint (JOA score). The arc of motion and the JOA score at discharge and at final examination significantly improved in patients with the three types of prosthesis. The loosening rates for the JACE, STABLE and KUDO prostheses were 15, 23, and 0%, respectively, although the follow-up periods were different. The loosening rate decreased to 2.5% when the humeral component was fixed with cement. Intraoperative fractures occurred in eight (10.1%) elbows and ulnar nerve palsy in six. Deep infection developed in three (4.8%) elbows and was treated by removing the prosthesis. Although there were considerable complications, the marked improvements in pain and function favor TEA in patients with rheumatoid elbow.

Upper limb function improvement following total elbow arthroplasty in patients with rheumatoid arthritis

Thirty-one primary total elbow replacements were implanted in 25 patients with rheumatoid arthritis between 2000 and 2004 by a surgeon. Twenty-six implants were GSB III. Seven were Coonrad–Morrey prostheses. The mean age of the patients was 70 years (40–88); 18 women, 6 men. DASH scores were recorded pre-operatively and at their latest review. Patients were also assessed according to the Mayo elbow performance score post-operatively. Mean follow-up was 29 months (8–55). The mean improvement in DASH (disabilities of the arm, shoulder and hand) was 25 (+6 to −45). The mean Mayo score (Corectly is the Mayo Elbow Score, there is also a Mayo liver score and other scores prposed in this center) was 85 (15–100). One implant was removed following deep infection (3%). One implant has been revised secondary to ulnar component fracture. Our overall major complication rate was 7%.

Total elbow arthroplasty in patients who have elbow fractures caused by gunshot injuries: 8- to 12-year follow-up study

In this retrospective study, we aimed to present 8-12-year clinical and radiographic evaluation of total elbow arthroplasty in young patients who had open fractures due to gunshot injuries. The study included a consecutive series of seven patients who had insertion of total elbow prosthesis (semi-constrained type) for the treatment of comminuted intra-articular elbow fractures resulting from gunshot injuries between 1994 and 1998. All patients were male and the mean age at the time of operation was 23 years. The average time from the original fracture to the joint replacement was 26 months (range 14-39). The mean follow-up period was 117 +/- 15 months. At the time of the latest follow-up, 5 of 7 elbows had a poor result. Radiological evaluations revealed that three patients had ulnar and two patients had humeral component loosening at the last follow-up examination. No intra-operative complications were observed. In the long-term evaluation, two patients had prosthesis loosening that resulted from deep infection and three patients had aseptic loosening that necessitated re-operation. The prosthesis removal was performed. As a result, the patients in whom we implemented total elbow prosthesis in comminuted elbow fractures due to gunshot wounds seemed to get back into active life in the early period without any problem and it seemed that their pain disappeared and their functional capacity increased. In the long period, however, these values showed a distinct decrease with the same patients.

Midterm Results of Revision Total Elbow Arthroplasty in Patients with Rheumatoid Arthritis

We retrospectively reviewed the clinical and radiographic results of 30 revision total elbow arthroplasties in patients with rheumatoid arthritis using original surface prostheses developed in our institution. We asked whether a surface prosthesis is a suitable option for reconstructing a failed surface total elbow arthroplasty in terms of reproducing clinical performance compared with other devices such as semiconstrained prostheses. All 30 failed total elbow arthroplasties were performed with various surface prostheses and revised with Dogo Onsen Hospital surface prostheses. The mean age of the patients at the time of surgery was 64.9 years (range, 44-83 years), and the minimum followup was 3 years (mean 6.7 years; range, 3-11 years). The Mayo elbow performance index improved from 42.3 preoperatively to 76.3 at last followup. Pain, stability, and function scores improved after revision surgery, but range of motion scores were unchanged. Our data indicate a surface prosthesis is a reasonable option for reconstructing failed surface total elbow arthroplasties in patients with rheumatoid arthritis.

Current concepts in total elbow arthroplasty

Purpose of review The aim of this article is to detail new developments and recent advances in total elbow arthroplasty over the past year. Recent findings This review will focus on several major topics: polyethylene wear in total elbow arthroplasty, the role of total elbow arthroplasty in fracture management, revision total elbow arthroplasty, unlinked versus linked implants and the role of total elbow arthroplasty in patients suffering from inflammatory arthritis. Summary As the popularity of total elbow arthroplasty has grown there has been a concomitant increase in the indications for total elbow arthroplasty use, and likewise revision total elbow arthroplasty. The current literature will help practicing surgeons delineate those patients and clinical situations for which total elbow arthroplasty is an appropriate treatment option, and offer strategies and techniques for revision surgery. Furthermore, recent research has focused on implant design and the development of prostheses with improved longevity.

Comparison of two types of ulnar component in type-5 Kudo total elbow arthroplasty in patients with rheumatoid arthritis

The purpose of this study was to assess the long-term results (more than ten years) of two types of cemented ulnar component with type-5 Kudo total elbow arthroplasty in a consecutive series of 56 patients (60 elbows) with rheumatoid arthritis, and to compare the results in elbows above and below a Larsen grade IV. There was no radiolucency around the humeral component. Patients in whom a metal-backed ulnar component and a porous-coated stem were used had better clinical results and significantly less progression of radiolucent line formation around the ulnar component. They also had a significantly better long-term survival than patients with an all-polyethylene ulnar component. The clinical results of arthroplasty using all-polyethylene ulnar components were inferior, regardless of the degree of joint destruction. We conclude that the type-5 Kudo total elbow arthroplasty with cementless fixation of the porous-coated humeral component and cemented fixation of a metal-backed ulnar component is acceptable and well-tolerated by rheumatoid patients.

Revision of total elbow arthroplasty for patients with rheumatoid arthritis

Revision of total elbow arthroplasty for patients with rheumatoid arthritis

Total elbow arthroplasty after previous resection of the radial head and synovectomy

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 Kudo total elbow arthroplasty in patients with rheumatoid arthritis

A Kudo total elbow arthroplasty (TEA) was performed in 36 elbows in 35 patients with rheumatoid arthritis. Of those 35, 4 died, 6 prostheses were revised, and 2 were lost to follow-up. Twenty-four elbows with a mean follow-up of 58 months were radiologically and clinically reviewed. Sixteen were scored as excellent by use of the Mayo score and Hospital for Special Surgery 2 score. The mean increase in active motion was 25°. Two humeral and four ulnar radiologic loosenings were noted. Two early dislocations were successfully treated with closed reduction and cast immobilization, two patients used an elbow brace after the closed reduction, and one patient underwent a resection arthroplasty for instability and deep wound infection. Four aseptic loosenings, of which three had an intraoperative fracture at the index operation and one had instability, were revised. Despite initially excellent results, longer follow-up of TEA in rheumatoid patients demonstrated deterioration of the outcome and increased loosening.

Early results of the Souter-Strathclyde unlinked total elbow arthroplasty in patients with osteoarthritis.

We have carried out a retrospective review of 11 Souter-Strathclyde primary total elbow arthroplasties in ten patients with osteoarthritis, over a period of nine years. The diagnosis was primary osteoarthritis in nine elbows and post-traumatic arthritis in two. The mean follow-up was 68 months (15 to 117). Although no patient was symptomatic, radiological review revealed evidence of loosening affecting three humeral and two ulnar components, one of which subsequently failed and was revised at 97 months. There were no dislocations, deep infections or mechanical failures. Complications included two superficial wound infections and two neurapraxias of the ulnar nerve which resolved. This study shows that the unlinked Souter-Strathclyde total elbow arthroplasty can be considered for patients with osteoarthritis and gives good symptomatic relief and improvement in function.

Kudo total elbow arthroplasty in patients with rheumatoid arthritis: a long-term follow-up study.

Improvements in the design of total elbow prostheses over the last two decades have led to better and more consistent results. The type-3 Kudo total elbow prosthesis was developed in 1980. The long-term results of use of this implant have not been reported. Because it is an unlinked prosthesis, it is not known whether preservation of the anterior oblique component of the ulnar collateral ligament at the time of implantation is important. A type-3 Kudo total elbow arthroplasty with cement was performed in forty-seven patients (fifty elbows) with rheumatoid arthritis. Revision rates, clinical symptoms, postoperative complications, and radiographic changes were assessed eleven to sixteen years (mean, thirteen years) postoperatively. The overall survival rate of the prosthesis was 90% at sixteen years. The mean Mayo elbow performance scores were all poor (mean overall score, 43 points) initially. The overall score was substantially improved at both the intermediate follow-up examination (four to six years after the operation) and the late follow-up examination (eleven to sixteen years after the operation), to 81 and 77 points, respectively. The overall rate of radiolucency about the humeral component was 45% at the intermediate follow-up examination and 100% at the long-term follow-up examination. The rate of radiolucency about the ulnar component at the intermediate and late follow-up examinations was 4.3% and 8.9%, respectively. No great differences in results were found with preservation of the anterior oblique component of the ulnar collateral ligament. This long-term follow-up study showed acceptable results of the type-3 Kudo total elbow arthroplasty in patients with rheumatoid arthritis. Preservation of the ulnar collateral ligament does not seem to be necessary when performing this procedure.

The effect of epidemiologic and intraoperative factors on survival of the standard Souter-Strathclyde total elbow arthroplasty

Previously published work has revealed an 87% survivorship after 12 years for the standard Souter-Strathclyde total elbow arthroplasty in patients with rheumatoid arthritis. Of the 13% that were revised, 75% were due to loosening of the humeral component. The aim of this research was to identify the specific epidemiologic and intraoperative factors that predisposed to this humeral loosening. Specifically, factors such as age, sex, radiologic staging of the disease, position of the implant in bone, and size of the implant inserted were evaluated. After analysis of 186 cases, we concluded that the position of the humeral component within the humerus is crucial for long-term survivorship. Specifically in the lateral plane, the stem should be aligned in the plane of the humerus and the implant inserted to the correct depth. The articular surface of the implant should lie at the level of the normal trochlea. At the anteroposterior plane, the implant should sit centrally and not be lateralized. We conclude that good surgical technique is crucial to the long-term effectiveness of this implant.

Long-term results of unconstrained Roper-Tuke total elbow arthroplasty in patients with rheumatoid arthritis

We evaluated the long-term results of 12 unconstrained Roper-Tuke total elbow replacements that were performed in 12 patients with rheumatoid arthritis from 1983 to 1989. The mean follow-up period was 9.5 years (range 8 to 13 years). We used the Ewald elbow-scoring system to chart results. This showed that the scores for the 12 elbows had improved from an average preoperative score of 39 points (range 17 to 72 points) to an average postoperative score of 80 points (range 45 to 97 points). The greatest improvements were in terms of pain relief, function, and range of motion. Eight elbows were free, of pain by the end of follow-up. Average elbow flexion increased from 115° before operation to 140° after operation, and pronation and supination increased from 52° to 61° and 42° to 71°, respectively. Radiographs of the 12 elbows showed constant wear of the ulnar polyethylene with loosening of 2 ulnar components. Revision of the prosthesis was necessary in 2 elbows because of aseptic loosening. Complications included 1 subluxation, 1 supracondylar fracture, and 2 ulnar neuropathies. Despite some excellent clinical results with a follow-up of over 10 years, the authors no longer recommend the use of this kind of elbow prosthesis in patients with rheumatoid arthritis because of the high complication rate and the impossibility of adapting this implant in the event of bone loss. The authors propose a new classification of humeral bone loss that will allow for better planning of primary and revision total elbow arthroplasties.

Total elbow arthroplasty in patients who have juvenile rheumatoid arthritis.

Patients who have juvenile rheumatoid arthritis often are seen at a very young age because of severe stiffness and pain in several joints. While total elbow replacement may be indicated in these patients, this procedure is difficult to perform because of contracture of the soft tissues and the extremely small bones and intramedullary cavities in these patients. As there is little information in the literature regarding this procedure, we attempted to learn about the long-term results by evaluating nineteen patients (twenty-four elbows) with juvenile rheumatoid arthritis who had been managed with total elbow arthroplasty. At an average of 7.4 years (range, two to fourteen years) after the operation, there was an improvement in the average Mayo elbow performance score from 31 points (range, 5 to 55 points) preoperatively to 90 points (range, 55 to 100 points). Twenty-two (96 per cent) of the twenty-three elbows available at the most recent follow-up evaluation caused little or no pain, but the improvement in the range of motion was not as reliable. The average arc of flexion improved from only 63 degrees preoperatively to 90 degrees postoperatively; the average postoperative arc of flexion began at 35 degrees, with additional flexion to 125 degrees. Examination of the four elbows that had been ankylosed before the procedure revealed an average arc of 73 degrees after the operation, and evaluation of the twenty ipsilateral wrists that were not limited by disease revealed that pronation and supination had been maintained. The average functional score improved from 9 points (range, 0 to 25 points) preoperatively to 23 points (range, 15 to 25 points) postoperatively (p < 0.001). The function of eighteen elbows (78 per cent) did not adversely affect the ability to perform activities of daily living. There were thirteen complications, including one perioperative death, that affected twelve of the twenty-four elbows. Seven of the nine early complications, including a fracture of the olecranon, subluxation of the prosthesis, stiffness of the elbow, and problems with wound-healing, led to an additional operative procedure but did not adversely affect the long-term outcome after appropriate diagnosis and treatment. Late complications (aseptic loosening, instability, and worn bushings) led to three poor results. None of the eighteen semiconstrained prostheses had radiographic evidence of loosening at the most recent follow-up evaluation. Of the twenty-three elbows that had been followed for at least two years, twelve (52 per cent) had an excellent result, eight (35 per cent) had a good result, and three (13 per cent) had a poor result.
