Abstract
INTRODUCTION: Constriction amniotic band syndrome (CABS) is a rare condition associated with the fibrous amniotic bands that restrict and ensnare the fetus in utero resulting in malformations at birth in one per around 15,000 live births. CABS associated with clubfoot, historically required extensive soft-tissue release due to its propensity for relapse. CASE REPORT: A 2-day-old Caucasian male infant born at 27 weeks gestation through emergency cesarean section due to concern for placental abruption and premature rupture of membranes in the setting of a prenatal history significant for oligohydramnios. The patient presented with non-viable tissue in the right leg requiring amputation with a left-sided clubfoot deformity. Following amputation of the right leg, the clubfoot was corrected with Ponseti method of serial casting and Achilles tenotomy. Three-week post-tenotomy and 6 months of age, a custom fit prosthesis of the right leg allowed for the application of a left abduction foot orthosis which maintained the correction. CONCLUSION: This case study supports recent literature that CABS-associated clubfoot can be corrected with the Ponseti method. While a contralateral amputation can prevent the use of a traditional bilateral abduction foot orthosis, a custom fitted prosthesis can allow for its use and prevention of a relapse of deformity.
