Sonographically-navigated frozen shoulder release (S-FSR): A modified technique for sonographically-navigated, in-office hydrodilatation of adhesive capsulitis

Abstract

We describe a new technique for hydrodilatation of the frozen shoulder, which we coined ‘Sonographically-Navigated Frozen Shoulder Release (S-FSR)’ or ‘Dr Gonzalez's technique.’ Traditional treatments include a combination of conservative and surgical modalities, such as non-steroidal anti-inflammatories, physical therapy, and open capsular release. We describe a modification to hydrodilatation of the frozen shoulder. Our technique describes the gradual dilation of the glenohumeral (GH) capsule with the goal of seeing a gentle release of the frozen shoulder. Furthermore, we outline our protocol for patient preparation with preprocedural diazepam 5   mg and Hydrocodone 5   mg-Acetaminophen 325   mg, one tablet each. During the procedure, we inject a solution of 10   mL lidocaine mixed with 2   mL of 40   mg/mL triamcinolone acetonide injection (80   mg total) through an anterior approach at the level of the rotator interval for pain control. Following this injection, we proceed to fenestrate the superior glenohumeral ligament (SGHL) in the process. We conclude the procedure with hydrodilatation of the GH joint (GHJ) through the posterior approach with approximately 50   mL of 0.9% normal saline, or until an expansion and release of the GH joint is visualized under ultrasound visualization.
