Study Details

Brief summary:

This study is to analyze the effectiveness of a nighttime extension orthosis after receiving a cortisone injection for the treatment of trigger finger to improve pain and restore functional outcomes. The investigators hypothesize that the extension orthosis will improve pain and functional outcomes compared to those without a digital night extension orthosis in those with trigger finger at 12 weeks from the injection.

Interventions and Outcome Measures

Arms

experimental: Experimental Group with Cortisone Injection of affected digit(s) and nighttime orthosis

The experimental group will consist of receiving a PIP joint on the day they receive their cortisone injection. The Oval-8 ® will be issued to the subject by an Occupational Therapist to ensure correct fit and comfort as well as given written instructions for night use. The orthosis will be worn at night for 6-week duration. Participants will have 1 follow up phone call or email at the 6-week mark and then 1 follow up phone call or email at the 12 week mark by a member of the research team from the time they received their cortisone injection where the time for resolution of trigger finger symptoms, VAS (Visual Analogue Scale), subjective questionnaire and QuickDASH scores will all be recorded in their medical research file.

active comparator: Control Group-No Orthosis

The control group will be identical to the experimental group except without the use of a nighttime orthosis. Participants will have 1 follow up phone call or email at the 6-week mark and then 1 follow up phone call or email at the 12 week mark by a member of the research team from the time they received their cortisone injection where the time for resolution of trigger finger symptoms, VAS (Visual Analogue Scale), subjective questionnaire and QuickDASH scores will all be recorded in their medical research file.
