Abstract
Introduction: This retrospective study examined the clinical characteristics, radiological findings, management, and functional outcome in 34 rehabilitated patients who presented with traumatic central cord syndrome.
Methods: Between 1994 and 2004 a total of 34 patients with central cord syndrome were admitted to the National Spinal Injuries Unit. There were 29 men and 5 women. The mean age was 56.1 years (15 to 88). The mean follow up time was 4.9 years. Patients were divided into three groups by age, < 50 years (10 patients), 50–70 years (16 patients), and > 70 years (8 patients). The American Spinal Injury Association (ASIA) system recorded the motor and sensory scores, of upper and lower limbs, on admission, discharge and during rehabilitation. Patients underwent radiological investigation that included plain film, CT, and MRI of the cervical spine.
Results: The mechanism of injury was a fall in 58.8%, road traffic accident in 35.2% and other in 6%. Alcohol was a contributing factor in 32.4% of cases. Seven patients had a spinal fracture. The cervical spine was involved in 5 cases with the remaining 2 cases involving the thoracic spine. Seventy percent of patients received intravenous steroids. Over half (53%) of the patients had some degree of cervical spondylosis while cord changes were seen in almost all of the patients (79.4%). In the majority of cases (70.4%) the affected level was C3/4. Disc herniation was present in one third of cases (33.2%). The mean upper limb ASIA score on admission was 7.6, on discharge was 12.4 and at follow up was 20.2. A similar pattern was also observed in the lower limb with scores of 12.1, 13.7, and 20.5 respectively. Sensory loss also improved with time. 88.2% of those admitted required urinary catheterization, with 23.5% being discharged to the National Rehabilitation Hospital with a catheter in situ. Surgical decompression was performed in 7 cases. The remainder of patients wore a Miami-J cervical collar.
Conclusion: As was shown in the original paper by Schneider et al (1954), hyperextension of a degenerative cervical spine was the predominant mechanism of injury. The return of lower limb function precedes that of upper limb, with autonomic function recovering in the majority of cases.
Discussion: In this study patients in the younger age groups had better recovery of function and had fewer complications. The original paper by Schneider et al. stated that conservative treatment was most appropriate, however, in this review surgery was performed in specific cases such as those with cord compression secondary to disc herniation. Alcohol was a significant contributing factor.
