Hemimelia is a birth defect consisting in unilateral or bilateral underdevelopment of the distal part of the lower or upper limb.[1] The affected bone may be shortened or not develop at all.[2][3]

Types of hemimelia

[edit]
Hemimelia of the right leg (complete absence of leg with foot on hip)

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]
