Which clinical finding is a red flag for undiagnosed vertebral fracture?

• A. Inability to lie supine
• B. Bruising over spine
• C. No trauma history
• D. No pain with percussion

Answer: (A)

In screening for vertebral fracture, an inability to lie supine is a red flag because it signals severe, focal spinal pain that worsens when the spine is placed in a recumbent position. This is especially concerning in older adults with osteoporosis or after minor trauma, where a vertebral fracture may cause such intense pain that lying flat is intolerable. It prompts urgent imaging and medical referral to rule out fracture. Bruising over the spine can occur with trauma but isn’t specific for a fracture and can be absent even when a fracture is present. A history of no trauma does not exclude a fracture, since insufficiency fractures can occur with minimal or no traumatic event. No pain with percussion would argue against a fracture, whereas vertebral fractures often produce tenderness to palpation or percussion over the involved vertebrae.
