Study Purpose: This research aims to find out which method helps people feel more comfortable when they break the upper part of their arm bone (called the humeral shaft) and need to keep it still at the hospital. The two methods are a brace and a splint.
Who Can Join: Adults over 18 with a new arm break that doesn't need surgery in the first two weeks can join. You cannot join if your bone is sticking out (open fracture), if you have many injuries, need surgery, are being treated for cancer, or are in prison.
- The study lasts for 2 weeks.
- You will have regular check-ins to track pain and comfort.
- No surgery needed during the study period.
Participants will help doctors understand better ways to care for broken arms in the emergency room. If you think you might qualify and want more details, please talk to the research team at the hospital.
