Congenital constriction ring syndrome with foot deformity: two case reports

INTRODUCTION: Congenital peripheral constriction ring originating from soft tissues of the leg that is characterized with compression in the soft tissue usually involving the deep fascia surrounding the leg at the time of birth is occasionally observed in lower extremity. At the region of the constriction, fractures of tibia and fibula and foot deformities like clubfoot can be observed. CASE PRESENTATION: In our report, 6-month and 8-month old infants with congenital constriction band and ipsilateral clubfoot were presented. They were treated with multiple Z plasties for their constricting bands and Ponseti method of serial casting for their clubfoot deformities. CONCLUSION: Congenital-constricting bands can be effectively released with multiple Z plasties. Ponseti method of correcting club foots of various causes can be applied to club foot deformities accompanying constricting bands.
