Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 2 - High volume (intervention) Suprascapular nerve block (SSNB)
10mL total volume injected around the supra scapular nerve (SSN)
9mL 0.5% bupivacaine and 1mL Celestone
Intervention will be administered once only

Intervention will be delivered by trained intervention radiologist or radiology registrar under supervision. The intervention will be an USS guided HCLA injection to the suprascapular nerve. This will be delivered as part of follow up through the outpatient orthopaedic clinic. Follow up will occur 6,12 and 52 weeks after injection.

The same radiologist will perform all injections to ensure adherence to the study protocol. All radiology reports will also be reviewed in clinic

Patients will be provided with comprehensive patient information sheet detailing the study, risks and benefits and contact information.

Power analysis:
Power analysis has been performed under the guidance of a statistician from University of Queensland.
30 participants per group are required
Parameters considered in the power analysis were as follows:

Expected CM score in intervention group following therapy is greater than or equal to 60 with a standard deviation of greater than or equal to 15
This data is based off a recent study that utilised CM score as the primary outcome following high volume SSNB This article included a population similar to the cohort that is proposed in this study

Summary
Brief summary
This study aims to determine if high volume HCLA SSNB injection leads to decreased pain and improved functional outcomes, when compared with low volume injection in patients with rotator cuff tears.

This will be a landmark study for SSNB HCLA injection volumes in the literature. This research will help create a standardised process for the administration of HCLA SSNB injections. At present, there is no protocol or guidelines in place that guide SSNB volumes. Evidence based processes could be created with this research and will have the effect of reliable and reproducible treatment which increase the efficacy and safety of treatment for patients.
