Talocalcaneal Coalition and New Causes of Peroneal Spastic Flatfoot

A case report of tibialis spastic varus foot with tarsal coalition.

“…Since then, several authors have reported the same condition and it has been recognized that talo-calcaneal coalition could also be a cause of it (Conwey, 1969;Cowell, 1972).…”

“…Cowell (1972) also stated with respect to the treatment of peroneal spastic flat foot that calcaneonavicular coalition, if detected prior to the onset of degenerative changes, should be treated by resection of the coalition. However, in my patient with caneo-navicular coalition a satisfactory result was obtained with conservative treatment.…”

“…Peroneal spastic flat foot is a well-known condition occurring in correlation with anomalies of tarsal coalition (Conway, 1969;Cowell, 1972;Harris et al 1948;Haris, 1965). Although it is accepted that tarsal coalition is an important factor of peroneal spastic flat foot, the mechanism by which the peroneal muscles are put into spasm is still obscure.…”

Tarsal Coalition

“…Tarsal coalitions may be isolated phenomena or may be associated with congenital malformation syndromes, including hereditary symphalangism, Apert's acrocephalosyndactyly, and the hand-footuterus syndrome (3,10,11). Many cases of peroneal spastic flatfoot are accompanied by tarsal fusions, although the former finding may also be caused by a previous fracture, osteoarthritis, tuberculosis, juvenile chronic arthritis, or other conditions (12)(13)(14)(15).…”

“…Conservative treatment includes the use of a medial heel wedge or medial longitudinal arch support. 13 Other authors 14,15 have reported success from foot supports, ankle foot orthoses, or 6 weeks of casting. Casting was reported as the most effective conservative method of care, but none of the options provided lasting relief.…”
