Shoulder pain is frequently encountered in the medical field. Rotator cuff tears are the most common cause. Shoulder pain affects quality of life and delay rehabilitation programs. Effective control of post operative pain is a cornerstone in the success of these surgeries. Regional anaesthesia is often favoured for shoulder surgery as it could effectively provide anaesthesia and postoperative analgesia. Additionally, the upper limb has multiple nerve targets that can be blocked. Ultrasound combined SSNB-ANB were described as an alternative to interscalene nerve block for shoulder surgeries equipotent pain relief and patient satisfaction as well as fewer complications due to the location of injection. Ultrasound guided SHAC block is a motor sparing block which targets all nerves supplying shoulder consistently at two sites. It was validated in chronic shoulder pain patients. However, there is no sufficient evidence for this block in postoperative pain after shoulder surgery.
