Treatment of severe planovalgus foot deformity in a child

Planovalgus foot deformity is one of the most common orthopedic conditions detected in childhood. According to the literature, it is present in 70% of children under 11 years with various degree of severity. Without timely correction, the common complications of this deformity are: arthrosis of the talonavicular joint, valgus deformity of the knee joints, impaired posture and functional scoliosis, pain syndrome, impaired function of the lower extremities, which is an indication for surgical treatment of this pathology. 
The article presents a clinical case report of surgical treatment of a patient with severe planovalgus foot deformity. The main stages of surgical correction were tendon-muscle plasty, subtalar arthroeresis and Cotton osteotomy (wedging osteotomy of the medial sphenoid bone). 
Relying on the results of surgical treatment of the patient, we conclude that the use of the combination of methods is valid for the treatment of patients with severe planovalgus foot deformity.
