英伦广角 为了改善表现而对健康的运动员做的韧带重建手术对身体是有伤害的（在线收听）

“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 okau 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.”
