Abstract
Introduction We have undertaken a retrospective study to identify prognostic factors predictive of neurological recovery after spinal cord injury (SCI).
Methods During the year 1999 to 2000, 403 patients with SCI were admitted and 91 patients could be followed-up for more than one year. Improvement in the motor score (ASIA) were taken as indicative of functional neurological recovery. Prognostic factors were simplified into static (which do not change with time) and dynamic (which may change with time). Variables like age, sex, mode of injury, mechanism of injury and skeletal level were static. Neurological level, sacral sparing, duration of spinal shock, reflex recovery, sensory & motor scores and complications like bedsores, flexor spasms, UTI, URTI, & DVT were dynamic. These were recorded at admission, at weekly intervals until discharge and at three monthly intervals in follow-up. They were correlated for any association with neurological recovery at one year. Regressive analysis of static and dynamic factors was done.
Results No significant correlation of static variables with the neurological recovery was found. First aid and transportation, duration of spinal shock, sacral sparing, rate of reflex recovery, flexor spasms and bedsores had a significant correlation with neurological recovery. Pin-prick sparing, spinal shock of < 24 hours and early appearance of deep tendon reflexes were good prognostic factors. Complete lesion, spinal shock for > 1 week, flexor spasms within three weeks and bedsore within one week were worst prognostic factor. Initial three weeks following injury was the critical period influencing final neurological and functional outcome.
