Design outcomes
Primary
| Measure | Time frame |
|---|---|
| This study will test the primary hypothesis that joint distraction yields similar outcomes, or even greater symptom reduction, compared to trapeziectomy with LRTI. This will be assessed using the PROMIS Physical Function Upper Extremity (PROMIS UE short form) score one year after surgery. | — |
Secondary
| Measure | Time frame |
|---|---|
| - There is no difference between group A (6 weeks distraction) and group B (trapeziectomy with LRTI) in MHQ, VAS pain, VAS satisfaction, VAS function, VAS stiffness, range of motion, and strength at 1 year after CMC1 joint distraction - There are no factors associated with PROMIS UE short form and MHQ at 1 year, including patient characteristics, PHQ-2 and PCS. - For the long-term effects, we will test all hypotheses mentioned above at 1 year 2 years and 5 years post-distraction | — |
