Background: Dorsolumbar trauma is the most common cause of paraparesis or paraplegia. Optimal goals of the management include establishment of a painless, balanced and stable spinal column with vertebral fusion. One of the general cause of Paraplegia is Dorsal-lumbar spine injury where damage to the dorsal- lumbar spinal cord that causes temporary or permanent changes in its function. Objective: The aim of our study is to evaluate Outcome of Surgical Management of Unstable Dorso-Lumbar Spine Injuries with Transpedicular Screws and Rods Fixation with Posterior Decompression. Methods: This observational descriptive study was conducted at Department of Orthopaedic Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2017 to January 2019 where 59 cases was observed and clinically Patients were graded using Frankel classification of neurological deficits pre-and postoperatively. Results: In this result injury where most of the patients face fall of height and D12 vertebra was fractured in 20 cases. Also Majority of the patients belonged to frankel grade A (71.18%). Most of the patients face fall of height 84.85%. Fracture in 59 case where D12 vertebra was fractured in most of the cases followed by L1 vertebra was fractured in 19 cases. Shows after posterior approach 17 patients presented with partial neurological deficit showed significant improvement after surgery. Fracture Pattern in Dorsal-lumbar Spinal Injuries where Common type of fractures were compression and burst fractures. Conclusion: After much analysis we can conclude that this rapid surgical management is safe and helps in early.
