Results of short segment posterior fixation in ao type c fractureof dorsolumbar spine

Introduction: Spinal injuries are one of the common injuries in road traffic accidents and high velocity traumas. Needs special attentions regarding its managements and rehabilitations. Thoracolumbar is the second most common segment involved in the vertebral column following cervical segment in patients with spinal injuries. The goal of treatment of any spinal injury is restoration of the patient to maximum possible function with disability free life. Initially, Long segment transpedicular fixation was done , which is providing stability to spine but in this type of fixation Motion segments of spine are involved which leads to rigid and fix spine. To overcome this problem, Short segment fixation is developed in which Motion segments of spine can be preserved without disturbing stability of fixation.in this study patients were managed with short segment spinal fixations and follow-up with various criterias regarding its out-come. Materials and Methods: 32 atients out of which 23 male and 9 female with thoraco-lumbar junctions injuries are managed with short segment posterior spinal fixation. And follow-up with various criteria regarding its outcomes such as vertebral heights attained, sagittal and anterior wedge angle, pain relief and complications such as inplant failure and infections. Mean duration of follow-up was 6 months. Results: in this study which was done on 32 patient. Mean age was 35.6 for males and 33.56 for females. The mean regional angle observed during pre-operative stages was 16.0 ° ±5.1and during pre-op-24th post op week it was 4.1° ± 4.2°. mean difference between this two is 11.95° and p<0.05 . the mean anterior wedge angle observed during pre-operative stages was 18.0° ±6.9° and during 24th post op week it was 5.2° ± 4.8°. mean difference between this two is 13.6° and p<0.05. The mean difference in vertebral height between the pre-operative stage and 6th post-op week was 7.96mm. in terms of complication one patient developed post-op infection. Conclusion: Short segment posterior instrumentation is a good implant system used in the treatment of vertebral fractures. There is a statistically significant restoration of vertebral body height, mean regional angle and mean anterior wedge angle, sparing of motion segments which are sacrificed in the conventional long segment fixation and avoiding morbidity of anterior approach for anterior reconstruction.
