ABSTRACT

Study Design: A case report. Objectives: Lumbar burst fracture was treated with operation, which delayed recollapse of L1 and led to conus medullaris syndrome. Summery of Literature Review: After operation, conus medullaris syndrome causing by delayed recollapse is not frequently reported. Materials and Methods: A 56-year-old male was admitted with lower back pain caused by a fall. Radiologic findings showed L1 burstfracture with about 42% of height loss. There was no neurologic deficit. Posterior fusion was performed using instrumentation. Fiveweeks after the operation, the patient was admitted for urination and defecation difficulty. Radiologic findings showed that the L1 hadrecollapsed with about 38% of height loss. To resolve the problem, anterior surgery was performed. Results: Two years after surgery, bladder and anal sphincter dysfunction wasn’t recovered. Conclusions: Lumbar burst fracture should be follow up carefully until union of the fracture because burst fracture leads to delayedrecollapse. Key Words: Lumbar spine, Conus medullaris syndrome, Burst fracture, Recollapse
