Unrecognized incomplete cervical spinal cord injury: review of nine new and 28 previously reported cases.

Nine patients with unrecognized incomplete cervical spinal cord injury are discussed. Four were sent home as normal, three were called hysterical, and two went undiagnosed during stupor or coma. A literature search revealed 28 additional cases. Eighty percent of these were males, two thirds were over 50 years old, and most had central or posterior cord syndromes. Falls with hyperextension, spondylosis, or disc disease, and motor vehicle accidents were the most common causes. Only one of the 37 had a cervical fracture. In some the neurologic problem was missed altogether; in others it was attributed to hysteria, intoxication, or to other neurologic or systemic diseases. Minor injuries without cervical fracture or dislocation, advanced age, unusual or changeable neurologic deficits, intoxication, and psychiatric problems all contributed to the confusion.
