Wrist Reduction Intervention: Supracondylar Technique for Radial Nerve Block vs. Hematoma Block (WRIST Block Study)

Conditions

• Wrist Fracture

Eligibility Criteria

Sex

ALL

Age

18 Years - N/A

Healthy Volunteers

Not accepted

Interventions

• Supracondylar radial nerve block — PROCEDURE
  Supracondylar radial nerve blocks given at the radial nerve not as the same location of the fracture site, prior to fracture reduction.
• Hematoma block — PROCEDURE
  Injection of analgesia into the hematoma that forms surrounding the wrist fracture.
• Combination of blocks — PROCEDURE
  Supracondylar radial nerve block given first, followed by hematoma block, before fracture reduction.

Study Details

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.

• Experimental: Combination of supracondylar radial nerve block and hematoma block
  Supracondylar radial nerve block given first followed by hematoma block

Primary Outcome Measure

Pain levels comparison [ Time Frame: Pain will be measured at (1) baseline, (2) after administering the assigned pain block(s), and after the (3) fracture reduction. ]
