Does "Freeze Spray" Work? Evaluating the Efficacy of Ethyl Chloride Usage Prior to Orthopaedic Injections
University of Chicago
Summary
A procedure frequently performed by orthopaedic providers is the administration of corticosteroid injections for the management of various soft tissues and joint-related conditions, such as osteoarthritis, tendinitis, carpal tunnel syndrome, trigger finger, and de Quervain's tenosynovitis. While these injections have demonstrated effectiveness in alleviating symptoms, the discomfort associated with the procedure can be a source of anxiety and apprehension for patients. This discomfort arises from the sensation of the needle entering the affected area and the burning sensation induced by the corticosteroid solution.
