Abstract
We analysed the outcome of the Coonrad-Morrey total elbow replacement used for fracture of the distal humerus in elderly patients with no evidence of inflammatory arthritis and compared the results for early versus delayed treatment.
We studied a total of 32 patients with 15 in the early treatment group and 17 in the delayed treatment group. The mean follow-up was 56.1 months (18 to 88). The percentage of excellent to good results based on the Mayo elbow performance score was not significantly different, 84% in the early group and 79% in the delayed group. Subjective satisfaction was 92% in both the groups. One patient in the early group developed chronic regional pain syndrome and another type 4 aseptic loosening. Two elbows in the early group also showed type 1 radiological loosening. Two patients in the delayed group had an infection, two an ulnar nerve palsy, one developed heterotopic ossification and one type 4 aseptic loosening. Two elbows in this group also showed type 1 radiological loosening. The complication rates in the early and delayed treatment group were 13% and 29% respectively. The Kaplan-Meier survivorship analysis for the early and delayed treatment groups was 93% at 88 months and 76% at 84 months, respectively. No statistically significant difference was found between the two groups.
We conclude that total elbow replacement provides a preditable and reproducible outcome in terms of pain relief and functional range of movement in elderly osteoporotic patients with difficult distal humerus fractures.
