Unlike the flexible flat foot that is commonly encountered in young children, congenital vertical talus is characterized by presence of a very rigid foot deformity. The foot deformity in congenital vertical talus consists of various components, namely a prominent calcaneus caused by the ankle equines or plantar flexion, a convex and rounded sole of the foot caused by prominence of the head of ...
A patient recovering from surgery to treat foot drop, with limited plantar and dorsiflexion.. Foot drop is a gait abnormality in which the dropping of the forefoot happens out of weakness, irritation or damage to the deep fibular nerve (deep peroneal), including the sciatic nerve, or paralysis of the muscles in the anterior portion of the lower leg.

Pes cavus is a multiplanar foot deformity characterised by an abnormally high medial longitudinal arch. Pes cavus commonly features a varus (inverted) hindfoot, a plantarflexed position of the first metatarsal, an adducted forefoot, and dorsal contracture of the toes.
An equinovalgus is a deformity of the human foot.It may be a flexible deformity or a fixed deformity. Equino- means plantarflexed (as in standing on one's toes), and valgus means that the base of the heel is rotated away from the midline of the foot (eversion) and abduction of foot. [1]
In cases where deformities are present in both feet, bilateral arthroereisis can be performed. Dorsiflexion of the foot is accomplished with the knee extended post surgical repair. Subcutaneous Achilles tendon lengthening is necessary if dorsiflexion is restricted until the foot can be dorsiflexed to 10 degrees. [14]
Acting via the Achilles tendon, the gastrocnemius and soleus muscles cause plantar flexion of the foot at the ankle. This action brings the sole of the foot closer to the back of the leg. The gastrocnemius also flexes the leg at the knee. Both muscles are innervated by the tibial nerve. [14]
The tibialis posterior muscle is a key muscle for stabilization of the lower leg. It also contracts to produce inversion of the foot, and assists in the plantarflexion of the foot at the ankle. [3] The tibialis posterior has a major role in supporting the medial arch of the foot.
