Suprascapular nerve block is an effective substitute for subacromial injection for non-operative
management of rotator cuff tears, especially the full-thickness tears.
The symptomatic
rotator cuff tears can effectively be managed with the implementation of a
suprascapular nerve block (SSNB), as per a piece of the study published in the
Journal of Shoulder and Elbow Surgery.
Participants
with symptomatic partial- and full-thickness rotator cuff tears selected and
obtained either an ultrasound-guided suprascapular nerve block (SSNB) versus
subacromial injection (SA). Shoulder function was considered as the primary
outcomes measured by modified Constant-Murley (CM) score and pain score at 2,
6, and 12 weeks after injection was regarded as the secondary outcome measured
by a visual analogue scale.
A total of 43
shoulders were examined, out of which 21 underwent SSNBs and 22 underwent SAs.
Nominal data and continuous variables were assessed by Fisher exact test (1
sided) and an independent t-test (2 tailed), respectively. SSNB group showed
significantly higher mean change from the baseline CM score as compared to the
SA group at six weeks and 12 weeks' follow up. The visual analogue scale score
also improved significantly within the SSNB group than another group at 12
weeks. As per these findings, SSNB can effectively reduce pain and improve the
functional outcomes of patients suffered from symptomatic rotator cuff tears.
