Abstract
Recent advances in spinal cord injury(SCI) management have markedly reduced mortality & morbidity, but concern regarding final neurological outcome is still at large. Global search is for prognostic-factors to predict neurological recovery. We statistically analyzed different variables to review the established and determine newer predictors of neurological recovery in SCI.
During 1999–2000, 403 patients were admitted. 91 could be followed up for more than one year. Improvement in the motor score (ASIA) was 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/mechanism of injury and skeletal level were static. These were recorded at admission and correlated for any association with neurological recovery at one year. Variables like 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 till discharge and at 3 monthly intervals in follow-up.
Bivariant & Regressive analysis of static and dynamic factors was done.
No significant correlation of static variables was found with the neurological recovery.
On bivariant analysis Pin-prick sparing, intact bladder, spinal shock of < 24 hours and early appearance of deep tendon reflexes were good prognostic factors. Complete lesion, priapism, spinal shock for > 1 week, bedsore within 1 week and flexor spasms within 3 weeks were worst prognostic factor.
When regressive linear analysis was done speed of recovery in the initial three weeks was the most important prognostic factor irrespective of other variables studied against the final neurological recovery.
All variables affecting neurological recovery have an effect on the speed of recovery, which is the single most important prognostic factor influencing ultimate recovery.
The initial 3 weeks following injury were the critical period influencing final neurological & functional outcome.
