“…In relation to range of motion and patient satisfaction, the results for our elbow arthroplasty patients were comparable with those reported in other studies (10,32,33). In a cross-sectional 50-month followup study of 18 RA patients (21 joints with Coonrad-Morrey endoprostheses), Hildebrand et al showed a mean DASH score of 53 (our patients 55.3), an SF-36 PCS of 27 (ours 37.2), and an SF-36 MCS of 56 (ours 52.3) (10).…”

“…There are multiple reports in the literature of the mid-and long-term results after elbow arthroplasty. However, most of these are based on examiner-dependent outcome measures; only few studies have employed standardized, valid, and comprehensive assessment instruments (7)(8)(9)(10)(11). Furthermore, no studies have examined the comparability of the various instruments used, in relation to their relative validity, clinical utility, or specificity.…”

“…Ideally, these features will contribute to postoperative stability of the implant and reduce peak forces at the interfaces (Herren et al 2001, McKee et al 2003. In our study of 20 GSB III semi-constrained total elbow arthroplasties in 16 patients with RA, the overall complication rate was one-third, which is comparable to other studies using semi-constrained designs (Ramsey et al 1999, Hildebrand et al 2000, Kelly et al 2004. 1 of the 20 replacements was revised due to aseptic loosening, and 5 replacements were reoperated for other reasons.…”

The GSB III elbow prosthesis in rheumatoid arthritis: A 2- to 9-year follow-up

BackgroundThe optimal design of an elbow prosthesis for badly damaged elbows is unkown. We evaluated 23 GSB III semi-constrained (sloppy-hinged) total elbow arthroplasties in 16 consecutive patients with rheumatoid arthritis.Patients and methods After a mean follow-up period of 5 (2-9) years, we assessed quality of the cementing technique, signs of aseptic loosening, patient satisfaction, range of movement, and determined the Hospital for Special Surgery (HSS) elbow score. 3 patients had died before follow-up; thus, 20 replacements in 16 patients were available for clinical and radiographic study. All patients had end-stage rheumatoid arthritis (RA) of the elbow joint.Results In 2 patients, humeral components were revised due to malorientation. 1 arthroplasty was revised due to aseptic loosening of the humeral component. There were 4 cases of intraoperative fracture which healed uneventfully. The total rate of complications was thus one-third. In 17 of 40 components, the cementing technique was rated as marginal or inadequate. We found no association between cementing technique and loosening. The arc of extension/flexion increased by 19º (0-80), and the range of pronation/supination increased by 31º (0-130). There were no cases of infection or ulnar nerve dysfunction. At the latest follow-up, the HSS elbow score was 84 (40-100) points. 11 of 20 elbows were rated as excellent, 4 elbows were rated as good, 2 elbows were rated as fair, and 3 elbows were rated as poor. 14 of 16 patients were satisfied with the result and the 2 patients who were not satisfied had persistent pain.Interpretation Despite the inherent problems of cementing in small-calibre medullary cavities, the clini-

“…4 The concept and goal of unlinked TEA is to share the loading stress on the joint surface/bone implant interface with the surrounding tissues such as the capsule, ligaments, and muscles. Although the loosening rate of unlinked prostheses should theoretically be lower than that of linked prostheses, there has been no definite evidence of this in clinical studies.…”

The History and Future of Unlinked Total Elbow Arthroplasty

Unlinked total elbow arthroplasty (TEA), which has no mechanical connection between the humeral and ulnar components, has theoretical advantages based on its near-normal elbow kinematics and the preservation of bone stock. Unlinked TEA is appropriate only for patients who have limited bone loss or limited deformity and good ligamentous function. This is because postoperative instability has been a major complication of unlinked prostheses. The concept and goal of unlinked TEA is to share the loading stress on the bone implant interface with the surrounding tissues. Although the loosening rate of unlinked prostheses theoretically should be lower than that of linked prostheses (which have a mechanical connection between the humeral and ulnar components), there is no clear evidence that unlinked TEAs are superior to linked TEAs in this respect. However, we believe that primary TEA should be performed using an unlinked TEA, especially for younger patients, because revision surgery for unlinked TEA results in longer prosthesis survival than revision surgery for linked TEA. Improvement of the design of unlinked prostheses and the introduction of less invasive surgical techniques are required to reduce postoperative instability.
