Step deformity is a skeletal deformity in which 2 adjacent bones which should be aligned with each other are displaced and are at different levels – resembling a step of a staircase
Examples:
Step deformity of spine
two adjacent vertebra are at different levels
can be identified by palpating the spinous process
spinous process appears prominent due to anterior/posterior displacement of adjacent vertebra (spondylolisthesis)
Step defromity of infraorbital ridge
seen in zygomatic bone (tripod fracture)
Step deformity of knee
seen in rupture of cruciate ligaments
results in displacement of tibia and fibula relative to femur
Step deformity below acromion
seen in separation …
