Spinal problems can occur as a result of the frequent falls suffered by young infants in the first years of life. A fall from a bed, a sudden stop in an automobile, or any significant unsupported movement of the head and neck in an infant can induce excessive movement in the spine causing vertebral subluxations. At the other end of the spine, the act of learning to walk, and the number of simple falls encountered in this way, can induce trauma to the lower spinal segments and to the large sacroiliac joints of the pelvis. Young children learning to walk also fall and hit their heads. Older children can suffer from sports injuries. These apparently innocent, frequently occurring events can also create spinal subluxations.
