It can include deficiencies, deformities, or discrepancies that make a limb appear different.
A limb deficiency is when a leg, arm, hand, finger, foot, or toe is crooked, uneven, partially formed or even missing. It can affect the whole limb or just part of the limb and can be congenital (present at birth) or acquired (the result of a disease, accident or other trauma).
A limb deformity is a misshapen limb. A deformity can affect the appearance and function of upper limbs like the arms, hands and fingers, as well as lower limbs like the legs, feet, and toes.
Limb length discrepancy
If it has a limb length discrepancy, which means the limbs are uneven, it may be caused by limb deficiency problems or complications from broken bone growth plates and may be the result of:
Failure of formation.
Too many bones and fingers.
Too few bones and fingers.
In the human body, there are two kinds of limbs, Upper limbs and lower limbs. Two Upper limbs are called arms, while two lower limbs are called legs. It has 4 limbs in total, in which 2 are upper limbs and other 2 are lower limbs. Upper and lower limbs consist of elements of the shoulder and hip girdles. A knee joints the upper and lower segment of each lower limb, while an elbow joints the upper and lower segment of each upper limb.
Limb difference is the partial or complete absence of or malformation of limbs (arms and legs). There are two main types of limb difference: congenital limb difference and acquired limb difference.
Congenital limb difference is also referred to as “limb reduction” or “congenital amputation” or “amelia” and occurs when someone is born missing all or part of their upper and/or lower limbs.
Acquired limb differences is also known as “amputation” and occurs when someone has a limb removed for medical reasons, or accidentally due to trauma.
