Delayed neurological insufficiency caused by transverse sacral fracture after minor trauma in elderly patients.

Sacral fractures in elderly patients with associated lumbosacral lesions can be overlooked easily because of vague symptoms and delayed neurological insufficiency. A 70-year-old female and a 73-year-old female presented with delayed neurological insufficiency caused by transverse sacral fracture after minor trauma. Both patients had suffered from lower extremity symptoms with dysuresia and dyschezia for more than a month. Coexisting lumbosacral pathological lesions may confuse the correct diagnosis for sacral fractures. Decompressive sacral laminectomy was performed, and the patients showed relatively favorable outcomes.
