title: Cubital tunnel syndrome in rheumatoid arthritis.
abstract: There has been an increase in reported cases of peripheral neuropathy and nerve entrapment syndromes in rheumatoid arthritis. (RA). To date, only a few incomplete studies on the prevalence of cubital tunnel syndrome (CuTS) in patients with RA have been reported. We investigated the prevalence of electrodiagnostic findings of CuTS in patients with RA and correlated them with the clinical findings. Forty-nine patients with the diagnosis of classic RA were evaluated clinically and by electrodiagnostic studies performed on the ulnar nerve, bilaterally, across the elbow. The study found 1 patient with slowing of both sensory and motor nerve conduction velocity (NCV), 8 patients with slowing of sensory NCV only, and 1 patient with slowing of motor NCV only. However, the correlation was poor between clinical and electrodiagnostic findings.
