SECOND GRAVIDA WITH POG of 15WKS 6DAYS
? LMP (Lactational Amenorrhoea).Uneventful first pregnancy .Present Sonogram findings are s/o Bilateral
club foot ( Talipes varus). Possibly isolated abnormality .
Rest of the scan per se was normal .
NORMAL FETAL FEET

FOOT WITH ASSOCIATED
HINDFOOT VARUS ) .
Inward deviation of both the fetal Feet is appreciated . There is associated hindfoot varus .
Rounding of the angle between feet and leg is appreciated .
Long axis of the metatarsals are visualized in the same plane as leg .
FOLLOWING SPECTRUM OF
ABNORMALITIES CAN BE ASSOCIATED WITH
CLASSIC TALIPES
•Hind foot equinus ( plantar flexion)
•Hind foor varus ( inward rotation)
•Forefoot adduction
•Forefoot cavus

CLASSICAL TALIPES
Spectrum of abnormalities associated with variable degree of contracture at ankle region /along with tendon abnormalities .
May be isolated or associated with neurological defects ( spina bifida) , neuromuscular ( FADS) ,environmental factors( oligohydramnios, uterine abnormalities , Early rupture of the membranes, Fetal crowding due to multiple gestation).
Two types : Talipes varus Talipes equinus
TALIPES VARUS ( CLUB FOOT)
Occurs in 0.1 to 0.2% of population.Recurrence rate after birth of first child with club foot is 2%
to 3% and if one parent is affected the recurrence risk is 3% to 4% .
Majority are isolated deformations. Early amniocentesis is associated with increased risk of club
foot . Normal foot can also achieve extreme dorsiflexion / plantar
flexion and caution should be exercised while making isolated diagnosis of club foot especially in late gestation.
Congenital talipes equinovarus has spectrum ranging from : Postural talipes / Non rigid deformity Severe rigid deformity .
