Dynamic varus heel cup: a new orthosis for treating pes planovalgus

Pes planovalgus is an extremely common deformity and still not completely understood. Its pathogenesis and the possibilities for treating it with shoe inserts are still under debate. While the controversy between abstentionists and interventionists remains a fact, since a certain number of flat feet persist into adult age and cause disability, a new type of orthosis is proposed. This has been tested on children affected with grade III pes planovalgus and with all the worst clinical, objective and prognostic parameters. The study was carried out with a control group using traditional Lelièvre insoles. The results were extremely good and correction was achieved in a significantly higher number of patients than in the control group.
