Carpometacarpal osteoarthritis of the thumb associated with uncommon concomitant hypoproteinemia mimicking irreversible carpal tunnel syndrome: Case report

Abstract

Carpometacarpal osteoarthritis of the thumb can be associated with various concomitant disorders such as the carpal tunnel syndrome. We describe an uncommon case of longstanding hypoproteinemia leading to irreversible thenar muscle atrophy and mimicking an advanced stage of carpal tunnel syndrome that required a thumb carpometacarpal joint arthrodesis despite some limitations of this procedure.
