Review Question - QID 5905

A 68-year-old woman presents to the emergency department complaining of lower back pain for the last 4 days after a ground-level fall. Her pain has been so significant that she has been unable to perform her normal activities. She also describes severe pain radiating into the left anterior thigh and knee and difficulty straightening her left leg due to weakness. She has no bladder or bowel changes. On physical examination, she is tender over the lumbar spine and has 3/5 strength in the left quadriceps. Imaging studies show an L3 burst fracture with 40% canal compromise and indeterminate posterior ligamentous complex (PLC) integrity. What is her Thoracolumbar Injury Classification and Severity (TLICS) score and what would be the most appropriate treatment?
