Oakland Athletics starting pitcher Jarrod Parker was diagnosed with a fractured medial epicondyle, A's head trainer Nick Paparesta informed beat reporters after Saturday's contest against the Seattle Mariners.
That's the bone where one end of the TJ graft is anchored. Unclear if TJ surgery will have to be repeated.— Susan Slusser (@susanslusser) May 10, 2015
Parker exited his Friday rehabilitation start with the Nashville Sounds after he fell to the ground in apparent excruciating pain. Parker will spend time with his family and consult specialists before undergoing surgery to treat the broken elbow. You probably know the medial epicondyle (initially called the "epichondral" by Nick Paparesta, based on beat reporter tweets) as the part of the humerus where, if struck, causes the tingling sensation in the ulnar nerve that gives rise to the phrase "hit your funny bone." You can imagine the pain when the epicondyle is broken.
For those asking, Jason Isringhausen is among those who have had three TJs. there are a handful.— Susan Slusser (@susanslusser) May 10, 2015
MLB.com's Jane Lee tweets that surgeons will not know if Parker's Tommy John graft is still intact until they open up his arm to repair the elbow fracture.
