Abstract

Pain management is an integral part of healthcare, and cryoneurolysis, a technique that uses extreme cold to disrupt nerve conduction, has demonstrated potential in managing both acute and chronic pain. It is an alternative for patients who do not respond to traditional pain management therapies. This review examines the efficacy, application, mechanism, limitations, challenges, and advancements in cryoneurolysis. Cryoneurolysis has broad applications, including acute pain management, reducing opioid dependency, and shortening hospital stays. It effectively treats chronic pain conditions like lumbar facet syndrome, phantom limb pain, occipital neuralgia, and, in some cases, unresponsiveness to traditional therapies. Furthermore, it offers values in tumor-induced neuropathies and postoperative pain. Cryoneurolysis has a favorable safety profile, presenting a low risk of minor complications such as infection and bruising, which resolve with proper care. Comparative studies indicate that cryoneurolysis, which induces Wallerian degeneration, is as effective as cooled radiofrequency ablation (CRFA), which achieves thermal nerve degradation to block pain transmission, particularly in knee osteoarthritis. However, its potential limitations impede widespread adoption, including small sample sizes, study heterogeneity, and the lack of standardized protocols. Future research should focus on large-scale trials, comparative studies with other pain management modalities, and developing standardized guidelines to enhance clinical outcomes.
