Combination of costoclavicular and upper trunk (CUT) block for the surgical repair of proximal humerus fracture in a severely obese patient

Effects of the costoclavicular block versus interscalene block in patients undergoing arthroscopic shoulder surgery under monitored anesthesia care: a randomized, prospective, non-inferiority study

“…This led us to speculate that if we could anesthetize almost all myotome and osteotome innervations of the shoulder joint, we could increase the acceptability of the CCB for intraoperative surgical anesthesia [ 14 , 15 ]. To date, clinical studies evaluating the efficacy and safety of CCBs as the sole anesthetic technique for proximal upper limb surgery have been limited [ 16 , 17 ].…”
