Primary degenerative arthritis of the elbow. Treatment by ulnohumeral arthroplasty.

Degenerative arthritis of the elbow is a poorly recognised condition, usually seen in a middle-aged man with an occupation or activity which involves the repetitive use of his dominant arm. Flexion contracture and pain at terminal extension are common presenting features. Fifteen patients were reviewed at a mean of 33 months after debridement by ulnohumeral arthroplasty. Fourteen had good relief of pain, elbow extension had improved by an average of 11 degrees and elbow flexion by 10 degrees. On an objective scale 12 of the 15 patients had good or excellent results and 13 (87%) felt that they were improved by the operation.
