Comparative efficacy of supra-scapular nerve block, posterior shoulder capsule hydro-dilatation, and shoulder interval hydro-dilatation in managing shoulder adhesive capsulitis

Although no significant differences were observed among the three groups, we recommend posterior intra-articular hydro-dilatation as it yielded the most promising and sustainable outcomes as regard pain reduction and range of motion improvement. Suprascapular nerve block is recommended for patients with prominent pain symptoms. Rotator interval hydro-dilatation is the least recommended intervention, being the most challenging and painful technique, and as it demonstrated a less sustained effect on range of motion. Key Points • This study aimed to find the best treatment modality for adhesive capsulitis through comparing the effects of suprascapular nerve block, posterior intra-articular hydro-dilatation, and hydro-dilatation of the shoulder interval. • Although no significant differences were found among three modalities, posterior intra-articular hydro-dilatation showed the best long-term outcomes for pain and range of motion. Suprascapular nerve block is recommended for patients with severe pain, while hydro-dilatation of the shoulder interval had less lasting benefits.
