Total elbow arthroplasty for treatment of elbow arthritis

- "Good results following elbow arthroplasty in the rheumatoid patient can be achieved with nonconstrained (Pöll and Rozing 1991, Ewald et al. 1993, Risung 1997, Kudo et al. 1999) and semiconstrained implants (Gill and Morrey 1998, Gschwend et al. 1999). Constrained elbow prostheses have been plagued with a high rate of loosening problems while nonconstrained implants have been associated with dislocation, ulnar nerve palsy, infection and wound problems (Ferlic 1999). The Kudo prosthesis is one of the most commonly used nonconstrained elbow prostheses. "

ABSTRACT: The Kudo prosthesis is the most commonly used elbow implant in Sweden. However, there are few reports of the results, besides those reported by Kudo himself. I have implanted 30 Kudo type 4 or 5 elbow prostheses in 28 patients with rheumatoid arthritis. 3 arthroplastics were revised, 2 because of loosening and 1 because of a periprosthetic ulnar fracture. 6 major peroperative or early postoperative complications occurred, but only 1 of these was a failure. 2 patients developed postoperative ulnar neuropathy, one was transient and the other patient died 1 year after surgery. 26 elbows were available for follow-up at an average 5 (2-8) years after implantation. All 26 functioned well although radiographic loosening of the humeral component was found in 1 patient. The average range of flexion increased by 14 degrees while the extension lag was unchanged (35 degrees). Activities of daily living had improved markedly and all but 3 patients were satisfied with their elbow. Radiolucent lines were seen around the proximal part of the ulnar component in 18/26 elbows. Although progressive in 1 patient only, this is a matter of concern, indicating that this component may be the weak part of the Kudo prosthesis.

- "The commonest are the non-constrained implants (Kudo, Capitellocondylar ), but semiconstrained implants (GSBIII, Conrad-Morrey ) are used for revision and in patients with instability. Of all total joint replacements, the elbow has the highest complication rate (Ferlic 1999). A questionnaire will soon be sent to all patients in the elbow register asking them about the functional outcome and their opinion of the proce- dure. "

ABSTRACT: Two new national orthopedic quality registers were started in Sweden in 1999, the Swedish Shoulder Arthroplasty Register and the Swedish Elbow Arthroplasty Register. Both are owned by the Swedish Shoulder and Elbow Section of the Swedish Orthopedic Association. The purpose of the registers is to improve surgical techniques and selection of implants and identify individual risk factors. Two of the main problems in starting a new national quality register involve inducing all centers in the country to participate and deciding on the data to register.
