A 12-year-old African tortoise that recently had its front left leg amputated due to injury is now moving just fine, thanks to a swiveling wheel attached to his shell by doctors at Washington State University's veterinary hospital, AP reports.

The tortoise is particularly good at moving toward food, and has gained 3 pounds since the wheel was attached.

The wheel allows the tortoise to move well on both flat and lumpy surfaces like lawns, and should last for years before it has to be replaced. （点击雅虎新闻网站查看原文）

乌龟安上假肢活动自如

       一只12 岁的非洲龟受伤后左前腿被切除，幸好华盛顿州立大学兽医医院的医生们为它在龟壳下安装了一个可以旋转的轮子，它现在才可以自如地爬行，冲向食物时尤其迅速。

       美联社报道称，自从安了轮子，非洲龟的体重已经增加了3磅。

       不管是在平地还是草坪等不太平整的路面，它都可以靠着轮子自由活动，而这个轮子能一直用好多年。
