Neglected clubfoot treated by serial casting: a narrative review on how possibility takes over disability.

The Ponseti Method is recognized as the best treatment for congenital idiopathic clubfoot in newborns and its principles became also adopted for treating older children with neglected deformity. This review aims to evaluate the role and effectiveness of serial casting in the treatment of neglected clubfoot, worldwide. Clubfoot is a complex tridimensional congenital foot deformity that can be easily treated after birth by correct manipulation of the foot and serial casting, with a great majority of cases requiring a percutaneous Achilles tenotomy, which can be organized as an ambulatory day procedure, without need for general anesthesia. However, in many low-income countries, treatment is not readily available, and many children grow up with disabling foot deformities. When compared to a newborn's clubfoot, a neglected clubfoot is different and more challenging to treat, as bones become ossified while malaligned and exposed to abnormal forces. Application of the Ponseti method in children with untreated idiopathic clubfoot older than walking age leads to satisfactory outcomes, has a low cost, and avoids surgical procedures likely to cause complications. The upper age limit for the use of Ponseti Method in clubfoot treatment is yet to be established. Success of clubfoot treatment is mostly defined as a pain-free, aesthetically acceptable plantigrade foot, with no need for extensive surgical tissue release after casting and tenotomy. The results of the Ponseti method for the treatment of clubfoot in children after the walking age are encouraging, with more than 80% of success in achieving initial correction and 18-62.5% of relapses. If Ponseti casting is not successful, any further interventions should be carefully selected and planned, in order to maintain the length of the foot and avoid intracapsular scarring or bony fusions.
