A Phase 4 interventional study of Supracondylar radial nerve block and Hematoma block in Wrist Fracture, sponsored by Sarasota Memorial Health Care System. Enrolling by invitation at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-26.

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.
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.
330 studies on the registry are indexed under Wrist Fractures; 73 are open to participants now.
This study's planned enrollment of 105 is above the median of 62 across 265 interventional studies indexed under Wrist Fractures.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Lidocaine injection given near the radial never under ultrasound guidance
Procedure: Supracondylar radial nerve block
Injecting analgesia into the hematoma that forms surrounding the wrist fracture
Procedure: Hematoma block
Supracondylar radial nerve block given first followed by hematoma block
Procedure: Combination of blocks
Supracondylar radial nerve blocks given at the radial nerve not as the same location of the fracture site, prior to fracture reduction.
Injection of analgesia into the hematoma that forms surrounding the wrist fracture.
Supracondylar radial nerve block given first, followed by hematoma block, before fracture reduction.
Pain levels comparison
Comparing pain levels among patients who are undergoing a wrist fracture reduction. Measured on a scale of 0-10, 0= no pain to 10= worst pain. Pain will be measured at (1) baseline, (2) after administering the assigned pain block (s), and after the (3) fracture reduction.
Time frame: Pain will be measured at (1) baseline, (2) after administering the assigned pain block(s), and after the (3) fracture reduction.
Amount of opioid medication needed to control pain.
The amount of opioid prescribed, if any, will be collected and recorded for comparison during patient's time in emergency room.
Time frame: Opioid medication prescribing will be assessed at baseline, time of admission to the emergency room, until the patient is discharged and they are no longer active in the study.
Number of patients requiring conscious sedation.
The need for conscious sedation among patients undergoing wrist fracture reduction in emergency care center will be recorded and monitored for comparison between groups.
Time frame: Patients will be monitored for need of conscious sedation from baseline, time of enrollment in the study, until discharge from the emergency room, when they are no longer active in the study.
Adverse Events Monitoring
Adverse events associated with any of the blocks that are administered to patients undergoing a wrist fracture reduction in the emergency care center will be identified, monitored, and recorded for reporting.
Time frame: From baseline, time the patient is admitted and enrolled into the study, until the patient is discharged and no longer active in the study.
