Abstract:
OBJECTIVES:To report a case of sacral stress fracture that developed after lumbosacral fusion.SUMMARY OF LITERATURE REVIEW: Sacral stress fractures rarely develop after lumbosacral fusion, and osteoporosis, female sex, being over 60 years old, and long segment fusion are known risk factors.
MATERIALS AND METHODS:A 66-year-old woman with spondylolisthesis at L5 on S1 underwent posterior lumbar interbody fusion and posterior instrumentation. A sacral stress fracture was found 4 weeks after the first operation, and we performed posterior reduction and posterior instrumentation with S2 alar screws.
RESULTS:The patient was free from symptoms and no further displacement was found at 3 months after the last operation.
CONCLUSIONS:Sacral stress fracture after lumbosacral fusion can be treated with posterior reduction and posterior instrumentation with S2 alar screws.
