RIGHT–LEFT ASYMMETRY

Dr Padmasini Srinivasan

Abstract :

Osteoporosis is a disease process that eats away bones that makes them weak and susceptible to fragility fractures. As the bone mass depends on many factors such as genetic, endocrinological, dietary and lifestyle we see that females are affected by osteoporosis more frequently due to menopause than their male counterparts and suffer from its complications in the form of fragility fractures .Metacarpal Radiogrammetry of left second metacarpal bone on hand x rays has been in vogue for more than half a century for detection of osteoporosis . This study demonstrates the bilateral asymmetry of second metacarpal bone radiogrammerically by studying various parameters on hand x rays using verniercallipers. Our study proves and confirms the finding that right second metacarpal bone in right handed females is significantly bigger in shape and size than left . Limb long bone asymmetry is well documented in literature.The left side bones are weak as compared to right so osteoporosis affects left side bones more than right consequently raising the susceptibility for fracture and its complications due to laterality. Thus osteoporosis can be easily detected on the left hand as compared to the right and may be a cause of more fragility fractures affecting left side upper limb bones than right .The natural asymmetry of the right and left hand bones and its consequences can be explained by factors that lead to more bone formation on right limb such as genetic, dominance and differential mechanical loading of hands.
