Mentally retarded people usually receive care in special social, vocational, behavioral or educational facilities. Only recently, we gained some experience in the rehabilitation after trauma of those with mental retardation. We presume that with the increasing awareness of the benefits of comprehensive and early rehabilitation after trauma, orthopedic surgeons, neurosurgeons, and physicians who work in intensive care units, refer more patients who had never before gained from this specialty. We would like to share our experience of the unique rehabilitation process of this population.
