What is the cause of Pes Cavus?
The most common cause of pes cavus is the hereditary motor and sensory neuropathies (HMSNs), the most common subtype being Charcot-Marie-Tooth (CMT) disease. CMT is a progressive degeneration of peripheral nerve myelin with decreased motor nerve conduction.
What is metatarsus varus?
Metatarsus adductus, also known as metatarsus varus, is a common foot deformity noted at birth that causes the front half of the foot, or forefoot, to turn inward.
What is rearfoot eversion?
Rearfoot eversion was defined as frontal plane movement of the rearfoot (calcaneus) during running. The angle between the line made by the upper two markers and lower two markers were defined as rearfoot eversion angle. Positive angles represent rearfoot eversion and negative angles represent inversion.
What causes a varus deformity?
Varus knee is common in newborns. In older children and adults, the condition is usually caused by improper bone formation due to rickets, cancer, or arthritis. Certain professions can increase one’s risk of developing varus knee. Various exercises can help reduce the pain caused by this condition.
What muscles cause pes cavus?
In many cases the cause is an imbalance between agonist and antagonist muscle groups. Common imbalances contributing to pes cavus include weak gastrocnemius and strong plantar flexors, weak tibialis anterior and strong hallucis extensors, and weak peroneus brevis and strong peroneus longus.
What bones form the rearfoot?
The hindfoot, sometimes also referred to as the rearfoot, is the posterior region of the human foot as differentiated from the midfoot and the forefoot. The hindfoot area includes the talus and calcaneus bones; the subtalar and talocrural (ankle) joints; and the muscles, tendons, and ligaments in the heel area.
What is rearfoot posting?
According to Dr. Phillips, the rearfoot post changes the angle the orthotic can assume inside the shoe as the foot strikes the ground, and it decreases the longitudinal flexibility and torsional flexibility of the orthotic once the anterior edge of the orthotic accepts weight.
What is primus varus?
Metatarsus primus varus is a foot deformity where the first metatarsal bone, which connects to the proximal phalanx bone of the big toe, is rotated and angled away from the second metatarsal bone.
What causes metatarsus primus Elevatus?
The etiology of metatarsus primus elevatus is either structural or functional. Structural etiology occurs from a congenital malformation or first metatarsal fracture, usually toward the base of the metatarsal. Functional elevatus is due to some form of muscle or biomechanical imbalance, or a combination of both.
What causes a rearfoot Varus?
Rearfoot Varus. Aetiology: Assumed to be due to a failure of the calcaneus and tibia to fully derotate from their foetal varus positions. 3 causes: 1) Tibial varum (tibial influence) – distal third of tibia is in varus – due to failure of tibia to correct from infantile position; genu varum of Blount’s disease 2) Varus angulation…
What causes anterior calcaneus Varus?
Assumed to be due to a failure of the calcaneus and tibia to fully derotate from their foetal varus positions. 3 causes: A varus position of the rearfoot complex may also be due to trauma.
What is the most common deformity in the foot?
Rearfoot Varus This is a positional deformity where the entire foot is inverted relative to the ground when the subtalar joint is in its neutral position, as shown below. This is by far the most common foot disorder we will see. Exists in about 85% of the patient population that has pronation problems.
Why do patients with rear foot Varus experience increased torsion/excessive deceleration?
Explain why patients with rear foot varus experience symptoms relating to increased torsion/excessive deceleration. – As heel lands in inverted position, the peroneals attempt to pull heel into eversion to correct. This results in overworked peroneals (and lateral muscle pain)
