About

This study evaluates the effects of T2 paravertebral block block improving interscalene brachial plexus block and superficial cervical plexus block on the relief of pain intensity during elderly proximal humerus fracture fixation surgery. The brachial plexus and cervical plexus block(IC block) will be performed in half of participants, while the T2 paravertebral block combined with IC block will be performed in the other half.
