Abstract

Introduction

An experimental study of experimental burst fractures in bovine spinal specimens was conducted to analyze the effects of transpedicular short-segment posterior fixation followed by reduction on indirect spinal canal decompression.

Materials and methods

For this purpose, experimental burst fractures were created in 11 bovine specimens with a hydraulic materials-testing machine. The specimens were evaluated with plain radiographs and CT scans before reduction. Thereafter, they were instrumented with titanium transpedicular screws and rods (short-segment posterior fixation); and reduction was achieved which included distraction and kyphosis correction maneuvers.

Results

Each spinal specimen was evaluated with plain radiographs and CT scans after reduction by applying distraction and kyphosis correction maneuvers. Plain radiographic analysis showed that the kyphosis angle and segmental height values improved. Furthermore, CT scans revealed that the spinal canal diameter values improved compared with those before reduction. The differences between before and after reduction in kyphosis angle, segmental height, anterior body compression, and percentage of retropulsion were statistically significant.

Conclusion

Short-segment posterior fixation followed by indirect spinal canal decompression led to an improvement over spinal canal retropulsion in experimental burst fractures. Furthermore, the kyphosis angle and segmental height values improved following the reduction compared with those before reduction.
