During correction of a BP sacrum, which maneuver is used?

• A. Push L5 posterior
• B. Push sacrum under L5
• C. Rotate sacrum
• D. Open disc space

Answer: (B)

The key idea is aligning the sacrum with the adjacent lumbar vertebra, particularly the L5, to restore proper lumbosacral mechanics. Pushing the sacrum under L5 directly repositions the sacral base so it sits correctly beneath the L5 vertebra, reestablishing a normal relationship at the lumbosacral junction and allowing the pelvis and SI joints to reset. This is the most direct way to correct a BP sacrum because it addresses the sacral position itself rather than moving the lumbar vertebra or rotating the sacrum in a way that doesn’t fix the underlying alignment. Pushing L5 posterior, rotating the sacrum, or opening the disc space do not restore that sacral–L5 relationship in the same targeted manner and thus are not the optimal correction for this presentation.
