Background and Aims:

Suprascapular nerve block(SSNB) is an effective and reliable treatment for many painful shoulder disorders. Procedure is usually  performed with the guidance of ultrasonography(US) by visulazing the nerve at the supraspinous fossa. Because of the anatomic variations at bony structures and relatively deep settlement of the nerve classical posterior technique can have difficulties in some cases.Suprascapular nerve originates from the C5-6 brachial plexus roots, course posteriorly-laterally under the omohyoideus muscle to the scapular notch. Our aim was to investigate the effectiveness of SSNB with supraclavicular approach by comparing with conventional block method.

Methods:

40 patients with shoulder pain lasting for more than 4 weeks were included in the study. Shoulder-range-of-motion(ROM) values were recorded. Visual-analogue-scale(VAS) for pain intensity levels and “disability-of-arm-shoulder-and-hand-questionnaire”(DASH) for evaluating pain related upper-limb disability were also taken. Patient were randomized into two groups.
The first group was SSNB done with supraclavicular approach. While the patients lying supine with linear ultrasound probe(E-SaoteMyLab5,18MHz) suprascapular nerve visualised under the omohyoid muscle. 5 ml %0,5 Levobupivacaine was given.
The second group was the conventional group .While the patient sitting position under the supraspinatus muscle suprascapular nerve identified and 5 ml %0,5 Levobupivacaine was given. 
After 3 weeks patients reevaluated.

Results:

Groups were similar according to ROM,VAS and DASH scores. All the parameters improved positively but there were no difference among both groups.

Conclusions:

SSNB done within supraclavicular approach is as effective as conventional method. We think this method is a reliable alternative to patients whom the SSNB is needed but cannot change position to sitting or lie prone.
