NERVE ENTRAPMENT AT THE ELBOW IN RHEUMATOID ARTHRITIS

: Although there was some delay in the posterior interosseous branch of the radial nerve conduction time in six of the 152 rheumatoid elbows, in no case were there clinical signs attributable to entrapment of this nerve. Some delay in ulnar nerve conduction was recorded in 27 of the 152 elbows; this was marked in 12. These patients tended to be older and to have more severe disease of the elbow.
