A rare condition where one or both shoulder blades are underdeveloped and abnormally high, leading to decreased range of motion in the neck and shoulders. Also called congenital high scapula, or congenital elevation of scapula, it has been reported as an autosomal-dominant inherited condition, but most often occurs sporadically due to a disruption in normal fetal skeletal development. More often seen in girls than boys, common signs and symptoms include nuchal rigidity, neck and shoulder muscle hypoplasia, muscle atrophy, and limited range of motion.

Management may include physical therapy to develop and maintain a greater range of motion and functionality. Surgery, when chosen, is recommended in early childhood (under 8 years old). Multiple surgical procedures include Green's procedure, scapula osteotomy, and the Woodward procedure.
