(A) A cystogram was performed and tissue was obtained for histological examination. (B) Under image-intensifier control, kirschner wires were drilled in appropriate positions on both medial and lateral cortices. (C) The entry holes of the nails were created with cannulated drills over the kirschner wires, and the nails were directed to pass through the bone cyst, one at a time. (D) Iliac crest bone marrow was mixed with demineralized bone matrix and the mixture was injected at the cyst.
