Detailed description: • Does local steroid injection have a role in treatment of spasmodic flat foot in adolescent patients? One of the most common foot complaints in the juvenile and adolescent age group is the "flatfoot" deformity. (1) Clinical evaluation of flatfeet primarily focuses on differentiation between the two main types: flexible and rigid. (2) The flexible type is a common diagnosis and is one which is usually not problematic and rarely needs treatment. (3) Rigid flatfoot deformity is less common (occurring one-third as often as the flexible type) but often is symptomatic and requires treatment. (4) Spasmodic valgus foot is usually associated with resistant pain and deformity. It shows controversy regarding its incidence, etiology, and treatment. (5) Spasmodic flatfoot is a rare condition characterized by a rigid and usually painful valgus deformity in the hind foot with peroneal muscles spasms (6,7) It is often caused by inter-tarsal bars or bone anomalies that restrict tarsal joint motion . (8) Our study aims to evaluate the functional and clinical outcome after local long-acting steroid injection in the sinus tarsi followed by cast in adolescent patients with spasmodic flatfeet without coalition.

* Age of the patients from 10 to 16 years
