Abstract
Split cord malformation is well documented and reported in various case series and reports in the literature. The excision of bony spur in type 1 split cord malformation is challenging due to the intricate pathologic anatomy. The standard method advocated is to excise the bony spur with the help of a high-speed microdrill and a forward cutting punch. We describe a novel method of using fine-tipped slender microrongeur, which can negotiate the narrow confines harboring the bony spur and protect the adjacent hemicords. The surgical nuances are detailed and discussed.
