60秒科学:Dodgers Doc: No Noninjury Tommy John Surgery to Improve Performance


60秒科学节目(SSS)是科学美国人网站的一套广播栏目,英文名称:Scientific American – 60 Second Science,节目内容以科学报道为主,节目仅一分钟的时间,主要对当今的科学技术新发展作以简明、通俗的介绍,对于科学的发展如何影响人们的生活环境、健康状况及科学技术,提供了大量简明易懂的阐释。

“There was a recent study that did a survey of parents and coaches asking them what they thought about Tommy John surgery.”

Dr. Stan Conte, vice president of medical services for the LA Dodgers, at the Society for American Baseball Research conference in Phoenix on March 13.

“And about 38 percent to 42 percent of the coaches and the parents thought it was okay to do a Tommy John surgery on their son that did not have an elbow problem in order to improve performance. This is dangerous stuff.”

Dangerous because that velocity does not increase on average after the surgery. The vast majority of pitchers do return to previous performance levels after a long rehab. But about 15 to 25 percent, depending on level of play, do not come back. And the shelf life of the surgery is limited. More major league pitchers are undergoing repeat Tommy John surgeries, with two being announced just this week.

“The parents come in and say, ‘Listen he’s throwing 78, he’s not going to get a scholarship until he’s throws 83, let’s do the surgery so he can throw 83.’ This sounds ridiculous, but it’s happening on a global scale. It’s ridiculous.”
