Recently I had a fairly serious case of cubital Tunnel Syndrome with symptoms of hand clawing and Froment's sign. However I have been told Froment's sign never happens with cubital tunnel syndrome. However the book "Anatomic Basis of Neurologic Diagnosis" states that Froment's sign is a cardinal feature of cubital tunnel syndrome. This book published in 2009 has been described by the "American Association of Neurological Surgeons" as "Superbly written" and the book description reads "...book that places special emphasis on the paramount importance of signs and symptoms for the accurate diagnosis of neurologic disorder." What am I a supposed to think of this??? Obviously I know Froment's happened with me but can someone explain why people would say Froment's sign wouldn't happen with cubital tunnel syndrome?
