Planar early phase (a), late phase (b) and SPECT/CT images of the right symptomatic (c) and left asymptomatic (d) wrist in a 59 year old female patient. On the right side trapezectomy and arthroplasty was performed 8 months before with persisting pain and increased late phase uptake in planar late phase (b short arrow) and SPECT/CT (c long arrow) beween trapezoid and base of first metacarpal bone. On the left side trapezectomy was performed 7 years ago and increased low grade uptake (arrow) is present between base of MC 1 and trapezoid bone without any symptoms. In the clinical examination 8 months after SPECT/CT examination the asymptomatic wrist is stable, range of movement normal but pain could be triggered by palpation on the exact localisation on base of metacarpal I and pisotriquetral
