Lateral hindfoot pain is generally due to impingement or arthrosis at the lateral hindfoot caused by an altered biomechanical force vector associated with hindfoot valgus .
An examination revealed bilateral hindfoot valgus and flatfoot deformities, and both feet were rigid and not reducible.
For stage IIB adult-acquired flatfoot deformity, the main pathological changes occur at the transverse tarsal joint with a characteristic of forefoot abduction and hindfoot valgus
In ankle valgus the callosity is under the medial malleolus and in hindfoot valgus under the talar head.
Hindfoot valgus is due to muscle imbalance, with shortening of the Achilles tendon, and a mid-foot break.
Shortening the fibula in patients with upper level fibular fractures associated with tibial fractures treated with intramedullary nailing may cause a dynamic hindfoot valgus
Other common findings associated with PTT dysfunction include hindfoot valgus deformity and forefoot abduction.
(13,18) This muscle functions as a plantar flexor and powerful inverter of the foot, it also provides support to the medial longitudinal arch, and stabilizes against hindfoot valgus and forefoot abduction deformities.
They are used to help control ankle pronation (eversion, or rolling in) and hindfoot valgus
(rolling out) position.
He had psychomotor delay and presented skeletal anomalies: left side metatarsus adductus with reducible hindfoot valgus
and bilateral reducible patellar dislocations.
Typically the physical examination of tibialis posterior dysfunction patients reveals a flatfoot deformity that consists of flattening of the medial longitudinal arch, hindfoot valgus, and abduction of the midfoot on the hindfoot.
The standing patient displays an increased degree of hindfoot valgus, apparent weakness of tibialis posterior function, "too many toes" sign, and inability to do a single leg heel rise; however patients still have a relatively normal arc of subtalar motion.
