Outcome Analysis of Indirect Reduction and Decompression by Ligamentotaxis with the Help of Pedicle Screw and Rod System in Thoracolumbar Spine Injuries

Outcome Analysis of Indirect Reduction and Decompression by Ligamentotaxis with the Help Of Pedicle Screw And Rod System In Thoracolumbar spine Injuries. Background- In thoracolumbar fractures which type of fixation is superior between short segment fixation, long segments fixation, intermediate screw fixation is not very well known. But due to lack of any powerful evidence it is said that with few pros and cons some are better than others. The aim of this study is to analyse the outcome of ligamentotaxis with the help of pedicle screw and rods system. Method- A study was conducted on 40 patients of thoracolumbar burst fractures. All patients were of age range from 15 to 60 years, among them 25 male and 15 female treated with conventional pedicle screw and rod (short segment fixation). Parameters evaluated are vertebral body height, kyphosis correction, neurological outcome, correction loss at follow up, instrumentation failure. Follow up period was from immediate post op to 3 years. Result- Patients improved in terms of vertebral body height restoration, neurological improvement (among 6 patients with grade A, 4 patients have improved upto grade C, while 2 patients improved upto grade B. Average kyphotic deformity decreased from 25.120 to 4.50. While implant failure seen in 4 patients and correction loss seen in 2 patients on follow up. Conclusion- With some implant failure, it is seen that ligamentotaxis with pedicle screw and rod is effective method in fixation of thoracolumbar injury.
