title: Aneurysmal bone cyst of medial cuneiform and a novel surgical technique for mid-foot reconstruction.
abstract: Aneurysmal bone cyst of the foot is extremely rare and the involvement of medial cuneiform has never been reported in the literature. In this report, we describe a 15-year-old boy who presented with a 6-month history of pain and swelling in his left foot. Radiograph demonstrated a lytic lesion in the medial cuneiform extending on to the middle cuneiform, the navicular bone and the base of the first metatarsal. En bloc resection of the lesion was performed using a dorsal longitudinal incision along the first ray. Tricortical iliac crest graft was harvested and shaped to fill the defect. Two drill holes were made and the tibialis anterior tendon was attached to the graft. Prepared, morcellised allograft was placed along the junction of autograft and host bone. At 1-year follow-up, the patient was pain free, the medial arch of the foot was maintained and the graft had united with the host bone.
