Ulnar nerve inflammation (neuritis)

Medical records documenting the diagnosis of ulnar nerve neuritis and describing the specific functional losses present are central to any rating evaluation. Nerve conduction studies and electromyography can provide objective evidence of the degree of nerve involvement. Physical examination findings are especially important: a VA or private examiner should describe whether you have any degree of "griffin claw" deformity, muscle wasting in the dorsal interspace or thenar and hypothenar areas, and how well you can extend your ring and little fingers, spread your fingers, adduct your thumb, and flex your wrist.

Because the rating turns on which arm is affected, records should clearly identify whether the involved arm is your dominant or nondominant side. Statements from you or people who know you describing how weakness, numbness, or loss of hand function affects your work tasks or daily activities can help show the practical impact of your symptoms. If your symptoms are entirely sensory — pain, numbness, or tingling without motor loss — the regulation limits the rating to mild or, at most, moderate, so records that distinguish sensory from motor involvement are relevant.
