Abstract: Apparatus 10 discloses a cranial orthosis for treating cranial deformities in infants. The device 10 conforms to the contour of an infant's head 18 and is used to correct positional plagiocephaly by redirecting the compressive forces that would otherwise be imposed on soft, compliant areas of the developing cranium. The device 10 is comprised of a frame member 12 housing having front 14 and rear 16 pads incorporating means for adjusting pressure 24 thereon. The cranial orthosis 10 has at least one removable panel 44 for relieving pressure during nighttime use. Alternate embodiments disclose devices having three pads 14, 54 in either an “X” or “Y” configuration.
