Types of hemimelia edit
Transverse hemimelia is a congenital absence of part or all of a limb (including hand or foot) and is called amelia when the entire limb is missing.[2][4] Paraxial hemimelia means partial absence of one of the elements of the limb in the longitudinal axis (in phocomelia there is no complete absence of a part of the limb).[2]
Sub types of hemimelia are the following:
- Fibular hemimelia, Congenital longitudinal deficiency of the fibula or fibular longitudinal meromelia[5]
- Tibial hemimelia, Congenital longitudinal deficiency of the tibia, Congenital aplasia and dysplasia of the tibia with intact fibula, Congenital longitudinal deficiency of the tibia or tibial longitudinal meromelia[6]
- Radial hemimelia, Congenital longitudinal deficiency of the radius, radial clubhand, radial longitudinal meromelia or radial ray agenesis[7]
- Ulnar hemimelia, Congenital longitudinal deficiency of the ulna, ulnar clubhand or ulnar longitudinal meromelia[8]
