Acute central and intermediate cervical cord injury.
Six cases with cervical cord contusion are described. All were over 50 years old, had an hyperextension injury of their cervical spine, suffered from tetraparesis predominant in the upper limbs and showed no X-ray evidence of injury to the cervical spine. Marked cervical spondylosis was present in five cases, one also had a narrow spinal canal. Cases No. 3 and 4 had an atypical recovery pattern. Shoulder and elbow movements improved last or not at all, while in the classic cases the hand muscles recovered last. Upper motor neuron damage was thought to be the cause, a result of intermediate instead of central cord traumatic necrosis or ischaemia. Pathological findings in case No. 5 emphasizes the possible diagnostic importance of taking lateral X-rays of the cervical spine in hyperextension. It also shows why laminectomy and/or myelotomy cannot help. Case No. 6 shows the noxious effect of shock and the effectiveness of steroid therapy.
