The key idea is that HVLA relies on the spine having intact structural stability. An acute fracture or dislocation means the bones or joints are unstable or disrupted, so a rapid thrust can worsen the injury by propagating a fracture, shifting bone fragments, or compressing the spinal cord or nerve roots. This carries a real risk of severe neurological or vascular injury, making it an absolute contraindication to lumbar HVLA.

The other scenarios don’t pose the same immediate, structural hazard. Chronic back pain without neurological signs isn’t inherently dangerous to manipulate if there’s no acute fracture. Mild scoliosis with normal bone density isn’t automatically disqualifying; adjustments to technique can be considered rather than excluding treatment. Recurrent headaches don’t specifically reflect a current lumbar spine injury, so they don’t establish an absolute reason to withhold HVLA in the lumbar region.
