류마티스 주관절염에서 발생한 척골 신경의 마찰성 파열

Abstract

Ulnar neuropathy around the elbow in patients with rheumatoid arthritis can occur by synovial invasion, flexion contracture or valgus deformity of the elbow. However, attritional rupture of the ulnar nerve by medial osteophyte with synovial invasion of the rheumatoid elbow is extremely rare. We reported a case of attritional rupture of the ulnar nerve by medial osteophyte in 62 years-old male with rheumatoid arthritis. Exact diagnosis and proper treatment are required if symptoms of ulnar neuropathy present in rheumatoid arthritis with contracture and valgus deformity of the elbow.
