Ulnar nerve compression in athletes
Regarding ulnar neuropathy in athletes, which of the following statements are true?
1.Cyclists are at increased risk of distal ulnar neuropathy because prolonged pressure on the handlebars compresses the nerve at Guyon's canal.
2.Baseball pitchers commonly develop ulnar nerve instability and irritation in association with repetitive valgus stress at the elbow.
3.Weightlifters are protected from cubital tunnel syndrome because muscular hypertrophy of the forearm flexors enlarges the cubital tunnel.
4.Padded gloves and altered grip position reduce ulnar nerve symptoms in cyclists by redistributing palmar pressure away from Guyon's canal.
5.Electrodiagnostic studies (nerve conduction studies and electromyography) are confirmatory rather than first-line investigations for athletic ulnar neuropathy and may be normal in early or dynamic disease.
