Congenital constriction band associated with pseudarthrosis and impending gangrene. A case report.

A newborn baby with a severe congenital constriction band associated with pseudarthrosis and impending gangrene of the foot is described. Early one-stage circumferential excision of the band with immediate wound closure by multiple Z-plasties salvaged the compromised foot. The pseudarthrosis indicated the severely compressive nature of the fibrous band. The uneventful healing of the pseudarthrosis and the full recovery of neurovascular function points to essential normal tissue underlying the constricting band.
