Pharyngula

Call me perverse, but my first thought on seeing this kid was that I desperately want to see an x-ray of the pectoral girdle. It looks to me from this one picture that the lower arm must lack a scapula or a clavicle, or at best have fragments with screwy and probably nonfunctional connections. I don’t understand why the doctors are even arguing about which arm could be more functional, if the article is correct. Or why they’re even considering it important to lop one off: if there aren’t circulatory defects or it isn’t impairing the function of the ‘best’ arm, why take a knife to him?

Poor kid. It does look like a very weird and fascinating developmental aberration, though, and it sounds like there are other internal asymmetries that are going to make life rough for him.
