What this Trial Is About
This research aims to evaluate how effective a nighttime extension orthosis is after receiving a cortisone injection for treating trigger finger, also known as stenosing flexor tenosynovitis. The goal is to see if wearing the orthosis improves pain relief and hand function compared to not wearing one, at 12 weeks after the injection. The study is a randomized controlled trial focusing on these outcomes in adults with trigger finger. Participants are divided into two groups. The experimental group receives a cortisone injection and is fitted with a proximal interphalangeal joint (PIPJ) extension night orthosis called the Oval-8®, which they wear at night for six weeks. The control group receives the cortisone injection but does not use the orthosis and is advised to move their fingers normally. Both groups have follow-up contact at six and twelve weeks to record symptom resolution, pain levels, and functional scores. During the study, participants will have assessments of their pain using the Visual Analogue Scale (VAS), functional ability via the QuickDASH questionnaire, and the timing of symptom resolution. These measures will be collected during follow-up phone calls or emails at six and twelve weeks after the injection. The study is sponsored by Cedars-Sinai Medical Center and will continue monitoring outcomes until May 2026.

Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
Duration - 6 weeks
Participants receive a cortisone injection for trigger finger. The experimental group also receives a proximal interphalangeal joint night orthosis to wear at night for 6 weeks. The control group moves their fingers normally without the orthosis.
1 visit for cortisone injection and orthosis fitting (experimental group only)
Duration - 6 weeks
Participants have follow-up phone calls or emails at 6 weeks and 12 weeks after the cortisone injection to assess symptom resolution, pain, and function.
2 follow-up contacts (phone or email) at 6 and 12 weeks post-injection
