title: Posterior interosseous nerve palsy in a patient with rheumatoid synovitis of the elbow: a case report and review of the literature.
abstract: A 54-year-old woman with rheumatoid arthritis developed loss of finger extension in the left hand. History, physical examination, and electromyography led to the diagnosis of posterior interosseous nerve palsy secondary to synovitis of the elbow. Anterior decompression and synovectomy resulted in a complete recovery. A literature review describes similar cases and compares outcomes.
