Scapular relocation descended the scapula by 60%, and achieved a normal shoulder joint motion. However, atlantoaxial rotatory subluxation developed, probably by pulling force of the tightened anterior fibers of upper trapezius muscle. Atlantoaxial joint was reduced easily under general anesthesia and muscle relaxant, along with surgical release of the tight band at the anterior part of trapezius muscle, which was maintained by halovest immobilization. © 2012 Lippincott Williams & Wilkins, Inc.
