Denervation point for neuromuscular blockade on lateral pectoral nerves: a cadaver study.

Purpose: The objective of our study was to clarify the topography of the medial and lateral pectoral nerves (LPNs) and the vascularity in the infraclavicular fossa and to propose an ideal injection point for neuromuscular blockade of the pectoralis major (PM) muscle.

Methods: The pectoral muscles and their nerves were examined bilaterally on 10 formalin-fixed cadavers. The PM muscle was dissected from its clavicular origin and sternocostal attachments.
