“…2,4 Risk factors that predispose infants to a hypercoagulable state (sepsis, thrombophilic disorders, maternal diabetes) or trauma (fetal macrosomia, difficult/traumatic birth extraction, oligohydramnios, amniotic band syndrome) have been implicated, but the exact cause of NCS remains poorly understood. [2][3][4][5] The severity of NCS ranges from transient ischemia causing minimal damage to severe compartment syndrome causing growth restriction, severe contracture, loss of limb function, and limb necrosis. 5 A previous case series and literature review of NCS reported at long-term follow-up 84% of infants had persistent contracture, 82% had radiographic bony abnormalities, and 45% had persistent nerve dysfunction.…”
