What does rearfoot varus mean?
A condition in which the rear of the foot tends to curve inwards at the ankle due to inversion at the subtalar joint. Those with rearfoot varus tend to be more susceptible to ankle sprains when landing after a jump. They usually need to strengthen evertors to help pull the foot back to its neutral position.
When correcting forefoot valgus with a wedge where should that be located?
Foot Posture Index (FPI-6)
| -2 | -1 | |
|---|---|---|
| Calcaneal frontal plane position (viewed from behind) | More than an estimated 5o inverted (varus) | Between vertical and an estimated 5o inverted (varus) |
| Prominence in region of TNJ (viewed at an angle from inside | Area of TNJ markedly concave | Area of TNJ slightly, but definitely concave |
Is forefoot varus or valgus more common?
The relationship between left or right extremities for forefoot or rearfoot deformities was not significant. The forefoot valgus deformity was the most common forefoot imbalance in this sample. Rearfoot varus was present in 97 (83.6%) of the feet surveyed.
What is uncompensated rearfoot varus?
In uncompensated rearfoot varus (A), the calcaneus (and forefoot) are inverted when the subtalar joint is neutral. The person compensates (B) by pronating STJ to allow medial heel to touch the ground.
What are the two forms of forefoot valgus?
Forefoot valgus is when the forefoot is everted while the calcaneus and subtalor joint are in neutral. The medial metatarsals lie below the calcaneus (plantar flexed in relation to the calcaneus). There are two different types: total valgus (all the toes slope down) or 1st ray plantarflexion.
How do you treat rearfoot varus?
Orthotics are a long- term solution to prevent reoccurrence by controlling and / or correcting the mechanics that cause the problem. Orthotics for forefoot varus should include: Heel cup and medial longitudinal arch support to align forefoot to hindfoot. Posting or wedging under the 1st metatarsal head.
When do you use a forefoot post?
This posting is most useful when controlling forefoot varus or valgus in sports where heel contact is short or there are large amounts of side-to-side motion in the activity. A runner’s wedge is incorporated in the same manner as the extrinsic long except with 3° of varus in addition to the forefoot intrinsic posting.
What is uncompensated forefoot varus?
Forefoot varus is the angling or inverted position of the bones in the front of the foot relative to the heel. In an uncompensated forefoot varus deformity, this causes the bones on the inside edge of the foot to sit higher off the ground than the outside of the foot when standing.
What is compensated forefoot varus?
The foot with a compensated forefoot varus requires STJ pronation to get the metatarsal heads to the ground. The calcaneus therefore, everts beyond vertical and the STJ is maintained in a fully pronated position throughout propulsion. The foot is hypermobile during the latter part of midstance and through propulsion.
What is mild hindfoot valgus?
Hindfoot valgus refers to malalignment of the hindfoot in which the mid-calcaneal axis is deviated away from the midline of the body. On the DP view, this results in an increase in the angle between the mid-calcaneal axis and the mid-talar axis (talocalcaneal angle) 1.
What is forefoot Varus?
Forefoot varus is when the forefoot is inverted (big toe higher than 5th toe) while the subtalor joint and calcaneus are in neutral. This foot abnormality almost always causes over pronation. Joint play is often excessive. Compensations include calcaneal eversion and navicular collapse to allow forefoot to contact the surface.
What is calcaneal valgus?
Calcaneal Valgus or Talipes Calcaneal Valgus or Flat feet are a condition where the foot surface which is in the contact with the floor is more than the normal feet.
What is the definition of valgus?
The classical Latin adjective valgus, valga, valgum means “bowleg” or “bowlegged” and applies to the appearance of the defect.
