    ABSTRACT: The increasingly precise knowledge made available in the last three decades about elbow biomechanics has made it possible to break new ground in the development of joint replacement devices conceived to restore function and do away with pain in elbows for the treatment which we had no efficient method only a few years ago. There are two types of designs supported by different rationales and having different indications: the unassembled ones, used for joint resurfacing, and the assembled ones, which are semiconstrained devices where the ulnar and humeral components articulate with each other via a hinge system. Both designs have shown their efficiency for the treatment for the rheumatic elbow but assembled ones are more commonly indicated for post-traumatic pathologies, especially when in cases where there is bone loss. Complications in elbow surgery are even more frequent than in other joints and are specific to each type of implant.

    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.

    ABSTRACT: Purpose : To evaluate the effect of radial head resection on longevity in nonconstrained total elbow arthroplasty, Materials and Methods : The results of 20 cases of radial head replaced Pritchard ERS and 18 cases of radial head excised Kudo elbow was followed for 6 to 16 years, 10.6 years in average. The rate of loosening, osteolysis, radial head subluxation, joint dislocation and valgus deformity were compared between the two groups. Results'There was no exaggerated cubitus valgus in Pritchard ERS group. However there developed one case of delayed subluxation of radial head occurred in 6 years postoperatively, one case of loosening, and one case of sponta- neous fracture of humeral shaft due to osteolysis. In Kudo elbow group,5 cases (27.8%) showed exaggerated valgus deformity with instability. There were one case of loosening and one case of delayed dislocation occurred in a year postoperatively. Conclusion : The most clear feature of Kudo elbow was exaggerated cubitus valgus. However, the ostolysis was developed in both groups and there was no difference in rate of the other complications between the two groups.
