Abstract
Neck pain is a prevalent issue associated with musculoskeletal disorders. This study describes the interfascial Levator Scapulae Plane Block (LeSP Block) technique, using ultrasound guidance for local anesthetic administration to treat chronic neck pain. Two patients, 1 77-year-old female and 1 50-year-old female, underwent the LeSP Block. Immediate postprocedure pain relief was achieved in both, with 1 patient experiencing complete pain remission (VAS = 0) and the other showing significant improvement (VAS = 2) after 30 days. The LeSP Block demonstrated effectiveness and ease of use, suggesting its inclusion in pain management strategies for shoulder girdle and scapular pain. Further anatomical studies aimed at improving the anatomical description of the accessory spinal nerve are recommended to refine the technique.
