The Ponseti method of clubfoot treatment in walking age children: is it effective? A study of 56 children from 1 to 10 years of age.

The Ponseti method is well-established for the treatment of clubfoot in younger babies; however, its effectiveness in older children is still unclear. The aim of our study was to report our results of the 'traditional' Ponseti method in the management of clubfoot in children of walking age. A total of 56 (81 clubfeet) children with a mean age of 3.16±2.35 years (1-10 years) were divided into two groups: group I consisted of 12 (18 clubfeet) patients with a mean age of 3.36±2.7 years (range: 1-8.4 years) who presented with an untreated clubfoot whereas group II consisted of 44 (63 clubfeet) patients with a mean age of 3.19±2.34 years (range: 1-10 years) who presented with a recurrent clubfoot. All children underwent the standard manipulation and casting technique described by Ponseti, including a percutaneous tenotomy of the Tendo Achilles. The bracing protocol was modified appropriately. All feet corrected with a mean of 7.36 (3-17) casts in group I and 4.49 (1-12) casts in group II. All children in group I and 70.45% in group II underwent a percutaneous Tendo Achilles tenotomy. There was a statistically significant change between the pretreatment and post-treatment Pirani scores in both groups. Nineteen (30.86%) patients underwent relapse at a mean follow-up of 2.84±1.25 years (1.2-5.4 years), who were treated by re-casting, bracing and tibialis anterior tendon transfer. The Ponseti method is effective even in walking age children upto the age of 10 years with a good success rate, although approximately one-third of the clubfeet relapsed and needed further treatment. No modifications to the standard casting protocol are required. Despite a high relapse rate, a supple, plantigrade and pain-free foot is achievable without the need for extensive soft-tissue surgeries or bony procedures. The Ponseti method lends itself well to developing a nation-wide program for clubfoot treatment in countries with limited resources. Level of Evidence: Level III.
