Ultrasound Guided Carpel Tunnel Syndrome Hydrodissection; It’s All About It

Abstract

Carpal tunnel syndrome (CTS) is one of the most common entrapment neuropathies leading to median nerve compression, with a high prevalence in the adult population. The term hydrodissection (HD) conveys a process of nerve fiber separation from adjacent structures, thus alleviating the underlying nerve compression, helping in pain relief, and improving nerve functions subsequently. Several methods with different techniques and different injectates have been studied with variable results. This review aims at highlighting the efficacy and safety of CTS ultrasound-guided HD, discussing and evaluating different techniques and modalities, and covering the most practical points of this technique with evidence-based recommendations for its use.
