The interscalene brachial plexus block is an effective intervention for reducing postoperative pain but is related to side effects, Suprascapular nerve block and a block of the axillary nerve have been introduced as alternatives to the interscalene brachial plexus for the control of postoperative pain. Previous study demonstrated new method of axillary block using interfascial plane injection guided by ultrasoud. Axillary block has been used widely for the relief of postoperative arm pain.~Recent study deomonstrated good pain relief when ultrasound guided interfascial plane injection was performed in patients with cervical radiuculopathy.~There is no study showing clinical efficacy of interfascial plane injection of axillary block in patients of cervical radiculopathy.
The primary endpoint of this study was to compare the clinical efficacy of axillary block in patients of cervical radiculopathy using 2 volumes of local anesthetics.
