CME OnDemand: Novel Imaging and MIS Techniques in Foot and Ankle Care (2026)-MIS in Metatarsus Adductus

Video Transcription

Video Summary

Metatarsus adductus is a congenital C-shaped foot deformity with medial deviation of the forefoot at the TMT joints while the hindfoot is neutral or slightly valgus, often due to intrauterine compression. It is common in women and strongly associated with hallux valgus: patients are ~3.5 times more likely to develop hallux valgus, and about one-third of hallux valgus surgery candidates have metatarsus adductus. Diagnosis relies on weight-bearing radiographs and angles (especially Sgarlato/modified Sgarlato), which are reliable and correlate with hallux valgus severity. Recognizing it is crucial because it affects surgical planning and recurrence risk.
