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.（点击英国《每日邮报》查看原文）

美国男孩截肢 足踝成膝盖

       据英国《每日邮报》报道，来自美国俄亥俄州的13岁男孩杜根•史密斯截肢后仍活跃在棒球场上打一垒位置，而这多亏接受了奇特的疗法，他的脚也因此前后调转。

       杜根10岁时不慎从树上堕地，股骨骨折，其后主治医师约珥书•迈耶森发现他腿上长有垒球般大的恶性肿瘤，而且不停出血。癌细胞扩散至肌肉，他被证实患上骨肉癌。

       手术切除了他右腿膝盖上下的肿瘤，再将小腿前后调转重新接上。

       手术后，杜根大腿截肢、小腿取代了大腿，足踝关节变成膝盖，其余部分则由义肢代替。最重要的是，他的癌细胞已被切除，可以再次回到棒球场上了。
