Efficacy and Safety of Hematoma Block Versus Brachial Plexus Block for Closed Reduction of Extra-Articular Distal Radius Fracture: A Prospective Study

Distal radius fractures are one of the most common types of fractures, affecting mostly youngsters and the elderly. Safety, ease of use, affordability, and effectiveness all play a role in analgesia during reduction. This study's goal is to assess how well the Hematoma Block (HB) reduces distal forearm fractures in a developing nation like Nepal. At a tertiary care hospital, a randomized comparative study is used. The individuals with distal forearm fractures that have been radiologically confirmed are enrolled after taking informed consent. When reducing distal forearm fractures, the patients are divided into two groups: Brachial Plexus Block (BPB group) and Hematoma Block group. We note the level of pain before, during, and after reduction using the Visual Analogue Scale (VAS) in both groups. The patient's radiological correction is assessed by Modified Sarmiento Criteria with an immediate post reduction radiograph.

Comparing Hematoma Block and Brachial Plexus Block, we can choose a definitive easy method for reduction that is easy, safe and less time consuming. Hence, the study will provide a guide for commonly occurring distal radius fracture.

Hypotheses of the Study:

Null hypothesis (Ho): There is no difference between feasibility, safety and quality of reduction in the two groups of anesthesia techniques.

Ho: Safety, efficacy and quality of reduction with Hematoma block = Brachial plexus block

Alternate hypothesis (H1): There is a difference between feasibility, safety and quality of reduction in the two groups of anesthesia techniques.

H1: Safety, efficacy and quality of reduction with Hematoma block ≠ Brachial plexus block
