posteriortibialvaltimo

Posterior tibial valgus, often referred to as posterior tibial valtimism or acquired adult flatfoot deformity, is a condition characterized by the outward rolling of the heel and flattening of the arch of the foot. This progressive deformity typically affects one foot, though it can occur in both. The primary cause is often a dysfunction or rupture of the posterior tibial tendon, a crucial structure that supports the arch of the foot and helps invert it. Over time, repetitive stress, age-related degeneration, or injury can weaken this tendon, leading to its failure to adequately support the arch.

Symptoms commonly include pain along the inner side of the ankle and arch, swelling, and a noticeable change in foot shape. As the deformity progresses, the foot may appear to turn outward, and the heel bone can shift outwards (valgus). Activities that involve prolonged standing or walking can exacerbate the pain. Diagnosis usually involves a physical examination where the doctor assesses the foot's alignment and the strength of the posterior tibial tendon. Imaging such as X-rays, MRI, or ultrasound may be used to confirm the diagnosis and evaluate the extent of tendon damage. Treatment options range from conservative measures like rest, ice, physical therapy, orthotic devices (arch supports), and specialized footwear to surgical interventions for more severe cases. Surgery may involve tendon repair or reconstruction, osteotomies (bone cuts to realign bones), or fusions to correct the deformity and restore foot function.
