Abstract
|
PURPOSE: Traumatic central cord syndrome (TCCS) is the most commonly encountered type of incomplete spinal cord injury. TCCS typically occurs in patients over the age of 50 with a narrow spinal canal and follows an acute hyperextension injury of the cervical spine. Here, we report on the demographics of TCCS patients, their clinical course and outcomes, and the factors that may have influenced these outcomes.
METHODS: We conducted a retrospective folder review of patients who presented to our facility between January 2004 and December 2008 following hyperextension injury of the cervical spine and with the clinical manifestations of a central cord syndrome. Patient details were obtained from the acute spinal cord injury register at Groote Schuur Hospital and the patient folders, radiographs and magnetic resonance imaging films were reviewed. Predetermined data points were identified, tabulated and analysed, with only information from the injury-related admission being included.
RESULTS: An ASIA motor score of ≥60 on admission or discharge correlated with an 80 % chance of being able to walk at discharge from hospital. An ASIA motor score of ≤50 on admission correlated with an 80 % chance of not walking at discharge. An ASIA motor score of ≤50 at discharge meant a patient was not only unable to walk, but required placement in a spinal injury rehabilitation centre. Further, if a patient had a cervical spinal canal diameter of ≥8 mm they had a 50 % chance of clinical improvement and nearly 80 % chance of a functional outcome.
CONCLUSION: The Groote Schuur Hospital patient population differs from the international norm, particularly with respect to age and mechanism of injury. The ASIA motor score and cervical spine canal diameter proved to be useful predictors of outcome. Within our patient group, timing of surgery did not appear to influence the outcome.
