Two infants had congenital atlantoaxial dislocation associated with myelopathy. One of them, a 3-month-old girl, showed anterior dislocation of the atlas on the axis, and had extreme weakness of the extremities. Another patient, an 8-month-old boy, showed tetraplegia, and posterior dislocation with absent odontoid process was demonstrated radiologically. These cases add another cause to the varied etiologies of floppiness in early infancy.
两名婴儿患有先天性寰枢椎脱位并伴有脊髓病。其中一名3个月大的女孩，表现为寰椎相对于枢椎向前脱位，四肢极度无力。另一名患者是一名8个月大的男孩，表现为四肢瘫痪，影像学显示齿突缺如并伴有后脱位。这些病例为婴儿早期肌张力低下的多种病因增加了另一个原因。
