Acquired Flat Foot due to Tibialis Posterior Rupture, a Known Yet Missed Cause

Abstract

AbstractRupture of tibialis posterior tendon is a known cause of acquired flat foot but the diagnosis is missed or delayed in most of the cases. It may lead to significant morbidity. We present a case of 13 years old boy with history of blunt trauma to his left foot one year back and presented with pain medial aspect of right foot and difficulty in prolonged walking and running. Clinically he had a flat and hyperpronated foot. His x-rays were normal and MRI revealed partial tear of posterior tibial tendon. He was recommended medial arch support, shoe modification, NSAIDs and referred to orthopedic surgeon for repair. Posterior tibialis tendon dysfunction is one of the concealed injuries that require earliest diagnosis and immediate attention, failing which the outcomes can have debilitating effects on patient's quality of life. This is important to prevent foot deformities and long term disability.
