Results of talectomy for inveterate or recurrent clubfoot

The aim of the present study was to define indications for talectomy in congenital paralytic, dystrophic or idiopathic, inveterate or recurrent, clubfoot.

Talectomy is a valid option for paralytic, dystrophic or idiopathic, inveterate or recurrent, clubfoot.

A single-center retrospective series comprised 52 clubfeet in 31 patients. Etiology was paralytic in 34 feet (65%) (17 arthrogryposes, 10 myelomeningoceles, 4 encephalopathies, 3 peripheral neuropathies), dystrophic in 6 (12%) and idiopathic in 12 (23%). In 27 feet, there was history of surgery (52%). Mean age at talectomy was 4.7 years. In 45 feet (87%), there were associated procedures (soft-tissue release, tendon surgery, calcaneal or lateral arch osteotomy, tibiocalcaneal fusion) and talectomy was isolated in 7 feet (13%). Mean follow-up was 9 years. Final assessment was based on the modified Ghanem and Seringe classification (G&S) and the Ankle-Hindfoot Scale (AHS).

All feet required at least one complementary procedure, either in the same step or as revision. Revision surgery was performed in 17 cases (33%), including all 7 feet with isolated talectomy (7 calcaneal tendon lengthenings, 10 mid- or hind-foot osteotomies, 6 tibiocalcaneal fusions, one calcaneocuboid fusion, and 2 progressive corrections by external fixator). Finally, 33 feet (63%) had good G&S results, 44 (85%) were pain-free, and 40 (77%) were plantigrade.

Talectomy for paralytic or dystrophic inveterate or recurrent clubfoot provided satisfactory medium-term results. Associated to other procedures, it achieves a pain-free plantigrade foot in most cases. Tibiocalcaneal fusion has an analgesic effect. Talectomy may, however, not be indicated in idiopathic clubfoot, given the patients' high functional demand and the existence of alternative treatments.
