All smiles: Dugan Smith's calf now acts as his thigh, while his ankle has become his knee. Prosthetics do the rest.

Dugan Smith, 13, of Ohio, is pitching and playing first base, thanks to a unique procedure that turned his foot backwards, the Daily Mail reports.

Dugan was 10 when he fell from a tree and fractured his femur.

Dr. Joel Mayerson said that while undergoing treatment, a softball-sized malignant tumor was discovered in Dugan's leg that was bleeding and polluting his muscles with cancer. He was diagnosed with osteosarcoma.

The surgery involved cutting above and below Dugan's knee to remove the tumor before flipping and reattaching the lower portion of his leg.

Now, Dugan's calf is his thigh, and the ankle joint acts as his knee, while the foot is now his ankle. A prosthetic ankle and foot do the rest. More importantly, he's cancer-free and playing baseball again.（點擊英國《每日郵報》查看原文）

美國男孩截肢 足踝成膝蓋

?????? 據英國《每日郵報》報道，來自美國俄亥俄州的13歲男孩杜根?史密斯截肢后仍活躍在棒球場上打一壘位置，而這多虧接受了奇特的療法，他的腳也因此前后調轉。

?????? 杜根10歲時不慎從樹上墮地，股骨骨折，其后主治醫師約珥書?邁耶森發現他腿上長有壘球般大的惡性腫瘤，而且不停出血。癌細胞擴散至肌肉，他被證實患上骨肉癌。

?????? 手術切除了他右腿膝蓋上下的腫瘤，再將小腿前后調轉重新接上。

?????? 手術后，杜根大腿截肢、小腿取代了大腿，足踝關節變成膝蓋，其余部分則由義肢代替。最重要的是，他的癌細胞已被切除，可以再次回到棒球場上了。
