Compare thumb arthritis surgery versus placebo surgery
Part of Bones, joints & muscles, Pain clinical trials.
This study compares a real thumb basal joint surgery (trapeziectomy) with a sham/placebo operation to see which option helps pain and daily function better. It is for people with thumb arthritis who have tried non-surgical treatments but still have significant thumb pain.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have thumb basal joint (CMC1) osteoarthritis confirmed on x-ray
- Your symptoms are severe enough to limit daily activities and you need surgery

- Your thumb pain is at least 4 out of 10 when you use your thumb
- You’re over 45 years old and can speak/read the study language

This study compares two surgical approaches for thumb base arthritis: replacing the damaged joint with an implant or removing the problematic bone. Researchers want to see which approach works better for pain relief and hand function.
This study compares two surgical approaches for severe thumb arthritis at the base of your thumb. Researchers want to see which surgery—replacing the joint or removing the worn bone—works better for pain relief and hand function.
This study compares different ways of keeping your thumb still (immobilizing it) after thumb base joint surgery. It aims to see which immobilization approach leads to better recovery and hand function.
This study tests whether an NSAID injection or a corticosteroid injection works better for thumb base arthritis. If you have ongoing pain despite using things like ibuprofen, ice, or a brace, this trial may help find which treatment offers better relief.
This study looks at how well different thumb (basal joint) surgery approaches restore strength and function. You would be having planned (non-replacement) thumb surgery, and your chosen surgeon would care for you while researchers compare outcomes.
This trial tests a surgery that replaces the joint at the base of the thumb to treat arthritis pain. It may help if you have thumb arthritis that hasn't improved with nonsurgical treatments.
