The suprascapular nerve block
The suprascapular nerve block (SSNB) is discussed in the literature but not widely adopted as a treatment option for certain shoulder conditions such as adhesive capsulitis or shoulder dislocation. In todays post, we will briefly review the anatomy, discuss the technique and review some of the literature on the indications.
Adhesive capsulitis, more commonly termed frozen shoulder, is an excellent candidate for SSNB. Ozkan et al found patients pain scores and range of motion significantly improved after SSNB.Ozkan, Korhan, et al. “Suprascapular nerve block for the treatment of frozen shoulder.” Saudi journal of anaesthesia 6.1 (2012): 52. Jung et al found similar effectiveness when they compared intra-articular injection with or without SSNB.Jung, Tae Wan, et al. “Does combining a suprascapular nerve block with an intra-articular corticosteroid injection have an additive effect in the treatment of adhesive capsulitis? A comparison … Continue reading The patients in the SSNB arm had better range of motion at both 2 weeks and 2 months follow up. At 1 year follow up, the SSNB group still had better pain and range of motion scores than the group that received intra-articular injection only. Shanahan had similar findings with reduction in pain and increased patient satisfaction scores.
