Dextrose Hydrodissection for Post-Breast Cancer Chest Wall and Axillary Tightness.

Detailed Description Post-surgical breast cancer survivors often experience persistent shoulder and upper-quarter dysfunction characterized by chest wall and axillary tightness. While conventional physical therapy focuses on joint mobilization and stretching, a subset of patients with significant soft-tissue fibrosis and scar adhesions-patterns reflecting extra-articular restriction-remains non-responsive to standard care. This prospective case series evaluates the role of ultrasound-guided dextrose prolotherapy as a targeted intervention for this challenging clinical problem. The rationale is based on the mechanical and biological effects of dextrose-based hydrodissection, which aims to separate adherent fascial planes and promote tissue remodeling in areas of postoperative myofascial restriction. Procedural Workflow: Scanning Protocol: A high-frequency linear transducer is used to systematically scan the ipsilateral pectoral and axillary regions. The physician identifies symptomatic areas characterized by tissue thickening, loss of normal fascial glide, or focal tenderness. Injection Technique: Using a sterile, ultrasound-guided approach, a dextrose solution is administered into the identified myofascial or perimysial planes. The injection targets are individualized based on each participant's specific site of restriction (e.g., between the pectoralis major and minor muscles or within the axillary fascia). Frequency and Duration: Participants receive a total of three injection sessions spaced 4 weeks apart. This interval allows for the observation of cumulative clinical effects and soft-tissue adaptation. Integrated Care: To maximize functional gains, all participants continue a standardized, home-based rehabilitation program consisting of progressive stretching and postural correction throughout the 6-month study period. The study aims to provide preliminary data on whether this interventional approach can bridge the therapeutic gap for survivors with persistent myofascial symptoms despite prior rehabilitation.
