Skeletal asymmetry.
Bilateral variations in dimensions of upper and lower limb bones are attributable to difference in mechanical stress and strain that the bones are subjected to during bone growth, and is referred to as directional asymmetry. This skeletal asymmetry in the upper limbs is usually prominent on the dominant side while in lower limbs on the other side, possibly due to supportive contra lateral muscle contractions, that influence the bone growth. This contra lateral dominance in upper and lower limbs is known as cross-symmetry pattern. During skeletal remains examination, variations in different dimensions of long bones of an individual can result in erroneous opinion regarding number of individuals, especially in case of mass disasters. A case report of skeletal remains examination with review of relevant literature is presented where the different dimensions of right and left limb elements are measured and compared.
