Rhizarthosis can be treated by prothesis of the carpo-metacarpal (CM) joint of the thumb. But, if the scaphotrapeziotrapezoid (STT) joint is also affected by arthrosis, treating the CM joint exclusively may result in partial pain relief. Thus, bone scintigraphy could identify early arthrosis of the STT joint when its appearance seems to be normal on planar radiography, suggesting another surgical procedure.
