Which condition requires avoiding HVLA due to risk of epidural hematoma?

• A. Osteoporosis
• B. Anticoagulants
• C. Ankylosing Spondylitis
• D. Pregnancy

Answer: (B)

Bleeding risk in the spinal canal is the key concern with this maneuver. When someone is on anticoagulants, their blood’s ability to clot is reduced, so any small vessel injury during a high-velocity, low-amplitude thrust in the spine can expand into an epidural hematoma. This collection of blood in the epidural space can compress the spinal cord or nerve roots, leading to rapid neurological decline and requiring urgent treatment. Because of this danger, HVLA manipulations are avoided in patients taking anticoagulants or with known coagulopathy, and safer, non-thrust or medically supervised approaches are preferred. The other options involve different risks (fragility fractures with osteoporosis, potential spine injuries with a severely fused spine in ankylosing spondylitis, and pregnancy-related anatomical/physiologic considerations) but do not specifically create the same acute risk of an epidural hematoma from HVLA.
