Conditions
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.
Interventions
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. Follo

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.
