[4] [5]Type A — The femur bone is slightly shorter on the proximal end (near the hip), and the femoral head (the ball of the thigh bone that goes into the hip socket) may not be solid enough to be seen on X-rays at birth, but later hardens (ossifies).
A baby hand affected by amniotic band syndrome. Congenital amputation is birth without a limb or limbs, or without a part of a limb or limbs.. It is known to be caused by blood clots forming in the fetus while in utero (vascular insult) and from amniotic band syndrome: fibrous bands of the amnion that constrict fetal limbs to such an extent that they fail to form or actually fall off due to ...
Anencephaly is the absence of a major portion of the brain, skull, and scalp that occurs during embryonic development.

One study found that male German Shepherd Dogs with a lumbosacral transitional vertebra are at greater risk for cauda equina syndrome, which can cause rear limb weakness and incontinence. [ 11 ] The significance of transitional vertebrae has been questioned by one study finding similar prevalence in the general population as those with low back ...
IV) partially fused femur, fused fibula V) partially fused femur VI) fused femur, fused tibia VII) fused femur, tibia absent. Sirenomelia is classified by the skeletal structure of the lower limb, ranging from class I, where all bones are present and only the soft tissues are fused, to class VII where the only bone present is a fused femur.
