Case Report: Ultrasound-guided hydrodissection targeting the subsynovial connective tissue with dynamic ultrasound assessment in refractory carpal tunnel syndrome: a report of two cases
Carpal tunnel syndrome is established to be caused by compression of the median nerve. However, recent studies have highlighted fibrosis of the subsynovial connective tissue and consequent restriction of median nerve sliding as a key pathophysiological mechanism. In this case report, we present the results of dynamic u...
