Nonconstrained Total Elbow Arthroplasty with or without Radial Head Resection Kim, Jung-Man; Chung, Yang-Kook; Kim, Yang-Soo; Huang, Seung-Hyun;
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.
