4. radiographs of the foot show diffuse infiltration of an osteolytic lesion into the midfoot area, suggesting the aggressive nature of the lesion. Jae Hoon Ahn et al. J Bone Joint Surg Am 2011;93:e133 ©2011 by The Journal of Bone and Joint Surgery, Inc.

5. A preoperative T2-weighted transverse MRI scan shows a large expansile mass replacing the medial two cuneiforms and also abutting the lateral cuneiform. Jae Hoon Ahn et al. J Bone Joint Surg Am 2011;93:e133 ©2011 by The Journal of Bone and Joint Surgery, Inc.

6. A line drawing shows the surgical plan, consisting of excision of the medial two cuneiforms and the proximal two-thirds of the first and second metatarsals, as well as the partial excision of the lateral cuneiform and the third metatarsal base.

9. A standing anteroposterior radiograph of the foot obtained at one year and two months after the operation and two months after the plate and screw removal shows the well-maintained length of the reconstructed metatarsal bones as well as solid consolidation...

11. A standing lateral radiograph shows that the fibrous union has occurred with mild extension of the distal portion of the graft, thereby decreasing the cavus foot deformity. Jae Hoon Ahn et al. J Bone Joint Surg Am 2011;93:e133 ©2011 by The Journal of Bone and Joint Surgery, Inc.
