Evaluation of the Efficacy of Suprascapular Nerve Block in Adhesive Capsulitis
Sponsor: CHU de Reims
Summary
This is a double-blind interventional superiority study evaluating the efficacy of suprascapular nerve block in addition to conventional therapies for adhesive capsulitis. Adhesive capsulitis is a pathology that results in reduced shoulder mobility due to retraction of the periarticular capsule. It may be primary or secondary to traumatic or neurological events, or associated with diabetes in particular. The usual treatment includes re-education sessions to improve joint amplitude and restore shoulder mobility. In persistent forms, intra-articular injection of cortisone is combined with distension of the capsule with a local anaesthetic under radiographic control. In some countries, subscapular nerve block (reversible anaesthesia) is used to improve pain. The combination of arthrodistension and subscapular nerve block has never been performed to accelerate the healing process. The aim of this study is to compare the performance of these two procedures together against the reference technique alone on time to improvement with the number of patients improved at one month according to the Constant score. This score is used to assess shoulder pain and function, with a significant improvement above eight points.

Conditions
Interventions
Triamcinolone Acetonide
1 injection of local anaesthetic (5 ml levobupivacaine 2.5 mg/mL) opposite the subscapular nerve, under ultrasound control, in a lateral decubitus or sitting position. Subsequently, they underwent Xray-controlled arthrodistension by injection of 1 ml of Triamcinolone Acetonide, combined with 10 ml of visipaque 270 contrast medium and 5 ml of Xylocaine.
saline solution
intramuscular injection of 1 ml saline under ultrasound control under the same conditions as the experimental group. Subsequently, they will undergo Xray-controlled arthrodistension under the same conditions as the experimental group
