Valgus Hindfoot Deformity Secondary to Neonatal Intravenous Infiltration

Orthopedic complications of intravenous (IV) infiltration are rare, with only a handful of cases reported in the literature. Because of the relatively high rate of IV infiltration in neonates, however, such complications do occur and can include growth arrest, limb length discrepancy, and joint deformities that require surgical intervention. The risk of these complications is highest in preterm neonates. A 7-year-old girl presented to our institution with a severe valgus hindfoot deformity that developed secondary to a neonatal IV infiltration injury. Management consisted of a medial displacement calcaneal osteotomy followed 5 years later by a triple arthrodesis, Strayer procedure, and free flap transfer.
