Hallux length and deep medial crease in complex clubfeet: Do they recover?

2020 
Abstract Objective The shortened hallux and deep medial crease are a significant cosmetic deformity in complex clubfeet. We quantitatively determined the correction of hallux length and deep medial crease following treatment of complex clubfeet. Methods A chart review of 11 patients (17 feet) with complex clubfeet treated with modified Ponseti method was undertaken. Pretreatment clinical photographs and Pirani scores were compared with those obtained at a recent follow-up to analyze outcomes. Hallux length was matched with 2nd toe and graded similar to Pirani score. Results Mean patient age at enrollment was 26.8 weeks. Average follow up was 22.6 months. Pre treatment and follow up Pirani score averaged 5.8 and 0.2 respectively. The average number of cast utilized was 7. Incomplete/ non correction of hallux was observed in 6 feet (35%), of which 4 suffered an equinus relapse. Deep medial crease corrected in all. Conclusions The study describes a clinical method of hallux length quantification in complex clubfeet. Medial crease recovered in all feet. The recovery of hallux length was delayed in some patients and might indicate persistent posteromedial soft tissue contracture/ fibrosis in these feet.
