Following publication of the original article [1], the author reported that the arrows, chevron and stars in Figs. 1 and 2 were removed during the corrections stage. These were added back to the images and the original article has been updated.

Ewing sarcoma of the proximal tibia in an 8-year-old boy. MR images show an extra-compartmental involvement and a partially circumferential (medial) respect for the CPU. Footnotes: arrows: axial edges; chevrons: level of the periosteal section

Fig. 2
figure 2

A Ewing sarcoma of the distal right fibula with purely intraosseous second localization in the homolateral proximal tibia in a 9-year-old boy. B Subperiosteal resection of the tibial localization with the previous site of biopsy. Tripod reconstruction was performed with non-vascularized autografts (2 fibulas and one tibia cortical). The distal fibula tumor was removed (at the same surgical time) (footnote: star: periosteum preserved). C Gross specimen with posterior and medial aspects. Proximal tibia without its periosteum and only the previous site of biopsy was resected with the tumor (footnote: star: anterior tibial tuberosity). D Serial radiographs showing rapid bone consolidation and good reconstruction. E Good functional result at 3-year follow-up. Little lower limb discrepancy. MSST = 28/30
