Corticosteroid vs 5% dextrose vs ultrasound-guided ozone injections for carpal tunnel syndrome

Effectiveness of Corticosteroid and 5% Dextrose Versus USG-guided Ozone Injections in Patients With Carpal Tunnel Syndrome: Three Blind Randomized Studies

Not applicable Interventional Ankara Etlik City Hospital · NCT07002892

This study will test whether a corticosteroid shot, a 5% dextrose injection, or an ultrasound-guided ozone injection helps adults with moderate carpal tunnel syndrome reduce pain and improve function.

What this trial studies

This is a randomized, triple-blind, three-arm interventional trial that enrolls adults with moderate carpal tunnel syndrome confirmed by EMG and randomizes them to one of three single perineural injections: betamethasone (with saline), 5% dextrose, or ultrasound-guided ozone. Seventy-two participants (24 per group) are randomized using computer-generated allocation and syringes are prepared and masked by a designated person to maintain blinding. The study is powered to detect a 20% change in pain VAS based on prior dextrose prolotherapy data, with follow-up assessments of pain and clinical function. Standard exclusion criteria remove patients with prior wrist surgery, significant neurologic or systemic disease, pregnancy, anticoagulation with warfarin, or prior corticosteroid injection for CTS.

Who should consider this trial

Good fit: Adults aged 18–65 with clinically and EMG-confirmed moderate carpal tunnel syndrome of at least three months' duration who have not improved with splinting or rest.

Not a fit: People with mild or severe CTS, prior wrist surgery, prior corticosteroid injection for CTS, the listed exclusionary medical conditions (e.g., pregnancy, inflammatory arthritis, current warfarin use), or other neuropathies are unlikely to benefit from participating.

Why it matters

Potential benefit: If successful, one of these injection options could provide a more effective non-surgical treatment to reduce pain and improve hand function in people with moderate CTS.

How similar studies have performed: Small prior studies have shown symptom improvement with corticosteroid and dextrose injections, while ozone therapy for CTS is less well studied, so this direct three-way comparison includes both supported and more novel approaches.
