The C Quad foot type is an under-pronator foot type with the following features:
- Moderately inverted heel alignment from Uncompensated Rearfoot Varus.
- Normal or neutral forefoot alignment.
- Medium arch.
- Restricted subtalar joint pronation and associated poor shock attenuation.
- Propulsion from the medial hallux.
- Calluses may form to the medial hallux primarily.
- Approximate presentation in US population is 25%.
This foot-type exists when an Uncompensated Rearfoot Varus is coupled with a relatively normal (neutral) forefoot alignment. A key distinguishing feature of this foot-type is an obvious toe-out gait pattern.
CHILD PRESENTATION: Usually presents without pain or associated problems. The best way to determine the progression of the child's foot is to evaluate older siblings feet or ask Mom and Dad to remove their shoes and socks.
WALKING PATTERN: Walks with a very toe-out pattern (external rotation at the hip), similar to a gunslinger (I think of one of my favorites: John Wayne). Can also be described as walking like a duck or a penquin.
POSSIBLE CLINICAL SYMPTOMS:
- Lateral Hip Pain
- Retrocalcaneal Bursitis (heel pain)
- Haglund's Deformity
- Lower Back Pain
- Iliotibial Band Syndrome
- Pinch Callus Medial Hallux (Great Toe)
- Equinus (Tight Achilles Tendon)
