About

The purpose of this study is to compare different types of local anesthesia-a supracondylar radial nerve block, a hematoma block, or a combination of the two-for reducing pain in people with a broken wrist (distal radius fracture). This is being done to find out which method provides better pain relief after the injury and during treatment in the emergency room.

Full description

This study is testing different ways to provide pain relief before reducing a broken wrist. Participants will receive one of three techniques: (1) a nerve block where a doctor injects lidocaine near the radial nerve under ultrasound guidance; (2) a hematoma block where a doctor injects lidocaine into the area where the bone broke; or (3) both the nerve block and the hematoma block. Patients will be asked how much pain they feel before the numbing, after the numbing, and after the wrist is reduced.

Enrollment: 105 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
