Final answer:
A deformity over 15 degrees generally requires compensations in multiple areas of the lower extremity to maintain a vertical loaded position.
Step-by-step explanation:
When discussing deformities in the context of podiatry or orthopedics, a common standard is that any deformity over 15 degrees necessitates compensations at multiple points of the anatomy to maintain a compensated vertical loaded position. At or above this threshold, the body might require adjustments not just in the rearfoot, but also in other parts of the lower extremity and potentially throughout the kinematic chain, to achieve a properly compensated stance.
