Clinical efficacy of hydrodistention with joint manipulation under interscalene block compared with intra-articular corticosteroid injection for frozen shoulder: a prospective randomized controlled study

摘要

Background: Hydrodistention is known to be an effective method of treatment for frozen shoulder. However, hydrodistention is accompanied by severe pain during the procedure. An interscalene block may relieve the severe pain associated with the procedure of hydrodistention. This study compared the clinical efficacy of hydrodistention with joint manipulation under an interscalene block with that of intra-articular corticosteroid injection.
