Hemimelia
Other names	Longitudinal meromelia

Terminal defect of an arm with transverse, incomplete hemimelia
Specialty	Medical genetics

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]

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]
