Regarding “A Multisite Injection Is More Effective Than a Single Glenohumeral Injection of Corticosteroid in the Treatment of Primary Frozen Shoulder: A Randomized Controlled Trial”

Abstract

We read with great interest the original research entitled “A Multisite Injection Is More Effective Than a Single Glenohumeral Injection of Corticosteroid in the Treatment of Primary Frozen Shoulder: A Randomized Controlled Trial” by Koraman et al.1 In this study, 76 patients with primary frozen shoulder (FS) were divided randomly into 2 groups, multisite injection and single glenohumeral injection. Assessments for clinical scores and range of motion (ROM) were performed at 1, 3, 6, and 12 months after injection.
