An 82-year-old male with a history of Parkinson disease and osteoporosis is brought to the emergency department by his son after a fall from standing height. The patient is found to have stridor and labored breathing, as well as reduced strength and sensation in all extremities. A plain radiograph is obtained, and a CT scan confirms additional vertebral fractures of the thoracic and lumbar spine.
