Linking structural variability in long bone
diaphyses to habitual behaviors: foragers from the southern African Later Stone Age and the Andaman Islands.
Radiologically, the hallmark of the disorder is bilateral, symmetrical cortical thickening of the
diaphyses of the long bones(14,15) on both the periosteal and endosteal sides of the
diaphyses.
In addition to bowing of the tibiae and fight fibula there were other bony lesions along the
diaphyses of these bones.
The tibial and femural
diaphyses were scanned at the midpoint (50%; Figure 1) of the bone, because this area consists almost exclusively of cortical bone.
Distal humerus breadths for the wolves are 42.2 mm and 42.3 mm, respectively, compared to a greatest Paleoeskimo specimen breadth of 40.2 mm (Qaja) The similarity in breadth highlights that the
diaphyses in the wolf specimens are proportionally longer, a routine pattern that characterizes wolf limbs in relation to morphologically generalized dogs.
When the lesion center is between the epiphysis and metaphysis, it is called "metapiphyseal." Lesions located between metaphyses and
diaphyses are called "metadiaphyseal" lesions.
