ObjectivePeriscapular pain has a broad differential diagnosis. Dorsal scapular neuropathy is part of that differential diagnosis but is often forgotten by clinicians, leading to delayed diagnosis, chronic pain, and potentially worse outcomes. The objective of this study was to describe our method for diagnosis, surgical technique, intraoperative findings, and outcomes in consecutive patients undergoing dorsal scapular nerve (DSN) decompression.MethodsA retrospective cohort study was performed to compile and describe outcomes for consecutive patients (n = 21) who underwent DSN decompression by a single surgeon during the period between August 2018 and February 2021. The primary outcome was change in visual analog scale (VAS) score for periscapular pain between baseline and 6 months postoperatively. Secondary outcomes included change in VAS score for overall pain, change in Disabilities of the Arm, Shoulder, and Hand (DASH) score, and change in the Zung Self-Rating Depression Scale (Zung SDS) between baseline and 6 and 12 months postoperatively.ResultsPatients undergoing DSN decompression showed significant improvement in VAS score for periscapular pain between baseline and 6 months postoperatively (mean score 54.0 vs 26.8, respectively; p < 0.001). Fifteen of 21 patients (71%) had a good outcome (score improvement ≥ 20). Disability (as determined by DASH scores) was significantly improved at 6 and 12 months postoperatively. The only factor that was predictive of outcome was symptom duration, with longer symptom duration predicting a poor outcome.ConclusionsSurgical treatment of dorsal scapular neuropathy is associated with significant improvements in pain and disability, and these improvements are durable. Morbidity associated with surgical treatment is low.
