II. Exam: Foot
- Lateral view
- Normal neonatal foot dorsiflexed >90 degrees
- Rule-out fixed equinus (Clubfoot) position
- Tiptoe walking (foot plantar flexed)
- Tight heel cord
- Plantar view (footprint shape)
- Kidney bean (sole deviated medially)
- Banana (sole deviated laterally)
- PA View (from behind, while in neutral position)
- Heel varus with inverted foot (medial malleoli apart)
- Heel valgus with everted foot (medial malleoli touch)
- Abnormal foot or leg Rotation
III. Risk Factors: Foot deformity
- Intrauterine compression
- Multiple Gestation
- Uterine malformation/myoma
- Uterine compression
- Increased uterine Muscle tone
- Oligohydramnios
- Fetal Macrosomia
- Non-vertex presentation (e.g. breach presentation)
- Extrauterine compression
- Maternal Hypertension (unclear mechanism)
-
General fetal hypotonia
- Central or Peripheral Nervous System disease
- Congenital Muscle disease
- Congenital Muscle imbalance (Myelomeningocele)
-
Family History
- Clubfoot
- Dislocated hip
IV. Associated conditions: Foot Deformities

V. Prevention: Shoe Recommendations for properly fitting shoe
- Adequate criteria met by inexpensive shoes
- Straight, no inward medial or lateral toe pressure
- Broad enough
- Toes assume natural, compressed standing position
