Is this trial a fit for you?

Likely a good fit

Adults over 18 undergoing outpatient rhizarthrosis surgery who have not previously received auriculotherapy and agree to complete study questionnaires.

Probably not a fit

Patients who do not respond to auricular stimulation or who do not experience pain reductions may see no benefit.

What this trial studies

This prospective, double-blind trial compares real auricular acupuncture to sham auriculotherapy in adults undergoing outpatient rhizarthrosis surgery. Participants are randomly assigned to receive either true ear stimulation or a placebo-like intervention, with pain and recovery measures collected postoperatively. The study uses standard follow-up questionnaires to assess pain outcomes and tolerability of the procedure. Recruitment targets adults over 18 who have no prior auriculotherapy and are eligible for outpatient thumb carpometacarpal osteoarthritis treatment at participating Paris clinics.

Why it matters

Potential benefit: If effective, auricular therapy could offer a non-pharmacologic option to lessen postoperative pain and improve recovery after thumb joint surgery.

How similar studies have gone: Previous findings in other settings suggest potential anxiolytic and analgesic effects of auriculotherapy, but high-quality evidence in this specific surgical context is still limited.
