Background: This study investigates the role of the dorsal scapular nerve (DSN) block in treating periscapular pain associated with scapular dyskinesia. Scapular dyskinesia is a prevalent condition causing shoulder dysfunction and pain, yet its management remains a clinical challenge.
Methods: Our approach included a comprehensive narrative review of existing literature and a detailed case study. The review encompassed randomized controlled trials, observational studies, and case reports, focusing on the efficacy of DSN block in treating periscapular pain associated with scapular dyskinesia.
Results: A total of 10 articles published on DSN for periscapular pain relief from 1993 to 2023. 3/10 articles reported ultrasound guidance in performing DSN block. 3/3 articles reported >50% pain relief.
Conclusions: The findings suggest that the DSN block is a promising treatment for scapular dyskinesia, offering significant therapeutic benefits. This study advocates for the incorporation of DSN block into clinical practice for managing scapular dyskinesia and calls for further research to explore its full potential and long-term effects.
