A Rare Case of Contiguous Three-level Lumbar Burst Fractures-treated with Combined Posterior Stabilization and Anterior Fusion.

Introduction: Burst fractures occur frequently in high energy trauma and are commonly associated with falls from height and road traffic accidents. While multiple burst fractures are not uncommon in thoracic spine, three or more contiguous level burst fractures are a relative rarity especially, in lumbar spine. The treatment of multilevel burst fractures must be individualized, and each fracture should be treated according to its inherent stability. To the best of our knowledge, this is the only case of such injury reported in English literature.

Case Report: A 17-year-old girl who sustained contiguous three-level lumbar burst fractures with neurological compromise following alleged history of fall from height. Radiographs/computed tomography scan revealed burst fractures of L2, L3, and L4 vertebrae with retropulsion of bony fragments at all the levels. Patient underwent minimally invasive posterior stabilization and anterior Hemi-corpectomy of L2, L4, and fusion. The patient recovered completely from neurological deficits by the end of 6 months.

Conclusion: Multiple contiguous burst fractures in the lumbar spine are a rare entity. To the best of our knowledge, this is the only case of such injury reported in English literature. The treatment requires a thorough assessment of the fracture pattern and often requires a combination of surgical approaches. Each fracture merits treatment based on individual characteristics of fracture patterns and the amount of canal compromise at each level.
