There are typically four classes (or types) of PFFD, ranging from class A to class D, as detailed by Aitken. [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 ...
Bones of human lower extremity X-ray image of fibular hemimelia type II (fibula completely absent) Characteristics are: [citation needed] A fibrous band instead of the fibula; Short deformed leg; Absence of the lateral part of the ankle joint (due to absence of the distal end of the fibula), and what is left is unstable; the foot has an ...
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 ...
A Chicago toddler who was born with a one-in-a-million condition that left him without part of his right leg is now walking thanks to a prosthetic leg. Dakari Miranda, who will turn 2 this fall ...
Formation of the sacrum/lower back and corresponding nervous system is usually nearing completion by the 4th week of development. Due to abnormal gastrulation, the mesoderm migration is disturbed. This disturbance results in symptoms varying from minor lesions of the lower vertebrae to more severe symptoms such as complete fusion of the lower ...
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.

An example is polydactyly, where a foot or hand has more than 5 digits. Clubfoot, one of the most common congenital deformities of the lower limbs, occurs approximately 1 in 1000 births. It can be treated by physical therapy, or by a combination of physical therapy and surgery. [1]
