Capitellocondylar total elbow arthroplasty
FC Ewald, RD Scheinberg, R Poss, WH Thomas, RD Scott and CB Sledge
Sixty-nine non-constrained capitellocondylar metal-to-plastic total
elbow-replacement prostheses were implanted in sixty-four patients with
rheumatoid arthritis. These patients were followed for an average of 3.5
years. Postoperative flexion and pronation were significantly improved, but
no significant increase in postoperative extension or supination could be
demonstrated. Based on a rating system evaluating pain and function, there
were 87 per cent good or excellent results. The complication rate based on
the total number of prostheses implanted was 39 per cent. Eight patients
required revision of the arthroplasty: four for dislocation of the
prosthesis, two for sepsis, one for loosening, and one for a fracture.
Eight other asymptomatic patients showed minimum radiolucent lines adjacent
to the ulnar component. No patient demonstrated radiolucent lines adjacent
to the humeral component.
