Abstract :

Introduction–Dorsolumbar spinal segment is an unstable zone between fixed dorsal and mobile lumbar spine⁽¹⁾ are the commonest site of spinal injuries. The treatment remains controversial^(2,3,4,5) for unstable fractures and fracture dislocations of dorsolumbar spine. The pedicle screws are passed one level above and one level below the fractured vertea via posterior approach. The aim of this study was to evaluate the use of pedicle screw fixation for preservation of remaining spinal cord function, restoration of spinal alignment, early mobilization and maximization of neurological recovery in Spinal Injury Patients. Materials and methods–Sixty–eight patients aged 18–65 years (mean 37.8 years) with posttraumatic instability (duration <3weeks) of lower thoracic or upper lumbar spine qualifying inclusion criteria were surgically managed at the Orthopaedics department, IGIMS, Sheikhpura, Patna. Results –Fifty–six patients(91.80%) out of sixty–one with incomplete neurological deficit had some amount of neurological recovery in terms of Frankel scale but no neurological recovery was seen in six patients(85.71%) out of seven patients with complete neurological injury. Mean correction of kyphotic angle was 11.74 degrees. Mean postoperative increase in anterior verteal body height was 42%. Complications like bed sore, superficial wound infections and peroperative dural tear were seen but all of which were treated successfully. Neurological deterioration after operation, screw pull out and implant failure were seen in none. Conclusion– Short segment pedicular screw fixation is a safe and effective method for treatment of unstable spinal injury.
