Comparison of 3 ultrasound-guided brachial plexus block approaches for cubital tunnel release surgery in 120 ambulatory patients.

We wanted to determine whether 1 of 3 brachial plexus blocks was best for one of our most common surgeries, the cubital tunnel release with or without transposition of the ulnar nerve. Brachial plexus blocks can provide excellent results for upper extremity surgery, but we noticed inexplicable block failure for cubital tunnel releases with an incision in the proximal arm. In this case series, we initially reviewed 90 patients receiving axillary, infraclavicular, or supraclavicular blocks to determine if one block performed better for a surgical procedure that proceeds up the inner aspect of the arm.
