Infection: purpura fluminans from meningococcal septicemia (may be multilimb)
Classifying Congenital limb deficiency

Longitudinal def named for ones partially or totally affected & fraction missing
Fibular Longitudinal Deficiency
Fibular hemimelia
Most common
Manifests as valgus foot, short leg, unstable knee &/or unstable ankle
Transtibial Deficiency
MC than transfemoral
Longitudinal def of tibial
