Practice questions
- In a CT study of paired femora and tibiae in skeletally mature subjects, which general pattern of bilateral variation was reported?
- A study measured bilateral lower-limb morphology in 361 skeletally mature subjects without bone pathology. Which method and imaging detail were reported?
- In the bilateral CT study, what was the reported mean left–right asymmetry in femoral anteversion?
- Which quantitative result best describes tibial version asymmetry in the reported bilateral CT study?
- A clinician assumes that the patient's opposite femur provides an exact template for femoral anteversion. Which interpretation is most consistent with the bilateral CT evidence?
- Which conclusion about the bilateral CT study is appropriately cautious?
- A developmental study examined long-bone surface features in individuals spanning fetal life through early childhood. Which age range was included?
- In the developmental surface study, which overall trajectory was described for long-bone surfaces?
- When interpreting vascular channels on a developing long bone, which orientation pattern was described in the developmental study?
- A developing femur shows persistent porosity and perpendicular bone spicules in a region associated with substantial muscle or fascial attachment. Which interpretation best fits the developmental surface study?
- A porous surface is observed on a femur from an infant. Which additional information is most relevant before interpreting the feature as abnormal?
- Which statement best captures why a baseline description of immature long-bone surfaces is useful?
- The developmental study compared lower- and upper-limb long bones. Which relative timing of structural stability did it report?
