A case of
rheumatoid thumb carpometacarpal (CMC) arthritis with advanced osteolysis is
reported.
Although CMC
joint arthrodesis was performed, bone union was not achieved, and pain and
instability persisted. Therefore, first and second metacarpal
bone fusion was performed with satisfactory results.
While CMC joint
arthrodesis or arthroplasty is typically performed, first and second metacarpal
bone fusion appears to be a useful treatment option when there is marked
osteolysis.
