patients was randomized into two equal groups. Group I received ultrasound-guided hydrodilatation with corticosteroid, saline, and local anesthetic via posterior intra-articular approach; group II received the same ultrasound-guided hydrodilatation via anterior rotator interval approach.~Both groups received guided stretching exercises for 3 months after injection. Baseline and 3 months evaluation of pain by visual analogue scale (VAS), shoulder pain and disability index (SPADI), and range of motion (ROM) had been recorded for all patients.~A statistical power analysis was performed after sample size estimation, based on data from the current study (N = 60), comparing group I to group II.~Qualitative data was expressed as numbers and percentages, and Chi-squared test, Quantitative data were expressed as mean and standard deviation.
A prospective randomized controlled study among 60 consecutive adhesive capsulitis to compare between the ultrasound-guided anterior hydrodilatation in rotator interval and the posterior approach.
