Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Search for a statistically significant association between scintigraphic STT hyperfixation and residual pain after TM prosthesis for patients with no radiographically obvious STT involvement. | before surgery and 4 month after surgery | STT scintigraphic hyperfixation and pain before surgery and 4 months after TM arthroplasty |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Search for an association between scintigraphic STT hyperfixation in quantitative analysis and residual pain after TM prosthesis for patients without advanced STT involvement on radiography. | before surgery | SUVmax STT and pain before surgery and 4 months after TM arthroplasty |
| Assessing the involvement of other carpal joint compartments | before surgery | Scintigraphic hyperfixation of other carpal joint compartments and pain before surgery and 4 months after TM arthroplasty |
