Abstract :

INTRODUCTION:

The spinal traumas are common and leading problem in orthopedic practice. Thoraco–lumbar fractures are serious injuries of concern, if left untreated may result in marked morbidity and disability to the patient. Thoracolumbar segment is second most commonly involved segment in the spinal cord following spinal injuries followed by cervical segment. It constitutes 40 to 60% of all spinal injuries. In this study, we stabilize the fractures of the unstable thoracolumbar

spine with or without decompression and pedicle screw & rods and fusion with bone grafts.

PATIENTS AND METHODS :

Patients of this prospective study comprises of 24 cases of dorsolumbar spinal injuries treated with short segment posterior stabilization with or without decompression in our institution

RESULTS:

All the 24 patients were operated for their spinal injury by posterior short segment stabilization by pedicle screws and rods system. 10 patients underwent posterior decompression by means of laminectomy, hemilaminectomy and 14 patients underwent indirect posterior decompression by means of ligamentotaxis, all underwent posterior stabilization and spinal fusion with cancellous grafts

Out of the 24 patients twenty patients showed neurological recovery to various Frankel grades. All patients had post–operative pain relief and no evidence of radiating pain. All patients showed good anatomical reduction and maintainence of the reduction in the post operative follow–up period. Results are categerised with categories such as 1.Post operative pain relief 2. Anatomical reduction and maintainence 3. Superficial and deep infections 4. Implant failure 5. Post–op neurological status 6. Locomotion 7. Bowel and bladder rehabilitation with scores of Good [11 to 13 ] Fair [7 to 10] Poor [0 to 6]. In our study out of 24 cases good result in about 19 cases, fair result in 4 cases and poor result in 1 case.

Conclusion:

In our series of twenty four cases followed up for a period of three months to sixteen months, ten cases underwent direct decompression and posterior stabilization and fourteen cases underwent indirect decompression and posterior stabilization. Posterior stabilization is done by means of short segment pedicle screws and rods system. Among them no patient showed neurological complication per–operatively.
