Beware The Five Inch Screw
Matt Garza heads to the DL for a "bone contusion" just above the elbow and his 25 man roster replacement, Lou Montanez finally winds up in the Cub starting lineup with a memorable night. As you recall, Montanez was the Cubs 2000 first round amateur draft pick (3rd pick overall) as a high school SS and after a stay in Cubville East (the Orioles System), he now resurfaces with the Cubs in RF. Getting back to Garza, let me think out loud with you readers about what seems to be the problem.
Let me stipulate that I AM NOT A DOCTOR (but I play one on tv)...so my opinions are just based on long miserable experience with the Cubs.
Garza's injury is being reported as a "bone contusion." Correct me if wrong but in my experience that's the same as saying he has a bone fracture except the fracture has no deliniation. Also, it's in his elbow so that implies that it involves cartilage as well as bone. This doesn't sound like something that heals in a week. Contusions often take longer than outright fractures to get better.
If the Cubs bring him back after missing one more start...look out.
In Garza's situation, using the term "bone contusion" is clearly an MRI diagnosis. I do have some issues with using this term here and (hopefully) I can provide some clarifications of muddy concepts being bandied about.
I love my headline (nope, I'm not going there, so shame on you) but you need to read on for some Serious Splainin' Lucy.
The diagnosis of "bone contusion" means that Matt Garza's X-Rays are negative for a fracture and the elbow MRI does show an abnormal signal in the area that his elbow is tender. The MRI is magnetic imaging which reflects changes in water content of tissues, so anything that changes the normal pattern on the imaging gets a descriptive term (an abnormal signal). If there is no linear signal seen in the bone, they won't use the term fracture. Not to be funny here, there are shades of gray to these signals. I assume the abnormal signal is in the bone (in this case the distal humerus) and probably does not extend to the soft tissues adjacent to the bone or joint, otherwise they would be worried more about the ligaments or tendons too.
Here's the local anatomy in a nutshell (some nice diagrams at the link). The medial or inside part of the elbow bone is called the medial epicondyle of the distal humerus and includes the flexor/pronator tendon origins (often referred to as "golfers elbow" when inflammed) and the nearby ulnar collateral/UCL or "Tommy John" ligament. The outside portion of the elbow bone is the lateral epicondyle and the tendon attachments, if inflammed, would be what is commonly referred to as "tennis elbow, or in medical lingo, "lateral epicondylitis" involving the extensor tendon origins that functionally extend the wrist.
For the diagnosis to be a contusion there usually is a history of direct trauma to the area. So I ask, when did that happen? Garza does not seem to indicate there was a direct trauma as his quotes below indicate. The Cubs doctors may be thinking it's a repetitive stress injury but are not willing to call it a stress fracture based on the abnormal uptake pattern on the MRI being more diffuse (rather than focal or linear) but the radiologist didn't come up with a better term for the signal abnormality. If this is the case the term "bone contusion" is misleading and what they really mean is the signal abnormality on the MRI is an early precursor to a stress fracture. The difference here can be subtle and it has to do with the normal bone remodeling process. If the repetitive stress/ trauma overwhelms the pace of bone remodeling, a structural break can occur, initially on microscopic level and just like a small car windshield crack that propagates beyond the ability to seal the defect, when a microscopic fracture propagates, the body shifts to a larger scale process of fracture healing and a clinically significant stress fracture occurs. This invokes more inflammatory changes as cells are mobilized that can lead to fracture healing. If my speculation is correct, the DL decision is an attempt to interceding before the problem becomes a stress fracture. This would be analogous to a leg injury from distance running often called "shin splints" which can progress to a formal stress fracture of the leg if the repetition continues and eventually overwhelms the bone remodeling process.
It's unlikely that there is any cartilage involvement in a bone contusion unless the direct trauma also affected the joint (that would make the diagnosis of an articular or intra-articular fracture) and one would see fluid (blood) in the joint on the MRI to make one consider that being the case.
From a Tribune article on Garza's elbow condition, Garza is quoted:
"There's a lot of reasons things like that can happen," he said. "It's just one of those things that happen, more wear and tear. Like, if you're a runner and your knees are sore, that's usually what it is -- a bruise."
The above quote bothers me as a "contusion" means some direct trauma and "wear and tear" is more of a repetitive stress problem. The "if you're a runner and your knees are sore" equals a bruise quote clearly comes from a lack of understanding orthopedic anatomy and diagnoses. I hope that's not what his doctor really told him.
Garza also is quoted in a video interview at CSN Chicago and reported at SB Nation saying that the injury is the result of throwing in cold weather and coming from the Rays, Garza isn't used to the cold (tongue meet cheek).
Again, this points to repetitive stress injury, not contusion.
In contrast, I recall Mark Prior's "bone contusion" to his right elbow when he was hit by a line drive by Brad Hawpe in 2005. They ultimately called the injury a "compression fracture." It was certainly more extensive than a "bone bruise" (OK, a severe bone bruise) yet his X-Rays were negative for a fracture so it took MRI imaging for the final diagnosis.
Finally, I remember former Brewer-WSox-Cardinal pitcher Cal Eldred, who had a diagnosis of "stress fracture" of his pitching elbow. He started the 2000 season with a 10-2 record with the White Sox but due to the stress fx, in August of 2000, had a 5 inch screw placed across the stress fx to try and heal it. He was mostly out until 2003 when he tried a brief comeback with StL before ending his career in 2005.
So, in summary and reading between the lines, I'm not sure what kind of estimate to recovery Garza has. If it's a "pre-stress fracture" or shin-splints equivalent at the elbow, it might be just the 2 weeks on the DL in the best case scenerio and that's enough rest for the bone to remodel. If he's not better or if this happens again...well, lets hope it doesn't become a recurring problem because a stress fracture at the elbow can be a bear to resolve.
Yes. That is something up with which we will not put.
Right, then. Moving forward lets focus on simple declarative sentences, subject-verb agreement, and watch out for punctuation. Avoid prepositions at the end of sentences.
I love sabremetrics and think FIP and WAR can definitely predict future success. For the Cy though which is an award for current success I do think ERA and WHIP have a place. Also while Hendricks doesn't have the strikeouts he does have the highest soft hit contact and second lowest hard hit contact which does a lot to take fielding skill out of it.
To me if the ERA is close FIP and WAR should be used but right now its not. That said I agree with you Hendricks won't get it.
Can't get soft just because we have a big lead!
kershaw will be lucky to put in 160+ip. even though it projects to be an awesome 160+ip it's going to be extremely difficult for him to do much with that. he's still got minor league rehab game(s) to go through and he's only stretched out to 2ip with his last simulated rehab...it may take another couple weeks before he returns.
the numbers are awesome, but he's lost the equivalent of a good chunk of a top-tier pen arm's season in innings of work compared to the rest of the lot.
Kershaw, Fernandez and Syndergaard are your current leaders and all will be pitching meaningful games down the stretch that could make or break them. Hendricks will not be and his saber-numbers aren't anywhere close to those 3 and he'd split votes with Arrieta and Lester whom all are basically neck-and-neck for WAR and FIP. If Kershaw pitches like just okay Kershaw in September he deserves to win in a landslide. Voters are pretty much saber-inclined now so it would take a crazy shutout streak or something for Hendricks to jump in the picture.
AZ PHIL: With starters the likes of Edwin Jackson, even Chris Rusin or Michael Bowden could look good on their staff. At best, he is a #5-6. But as always, LH are at a premium.
Sure we would all want consistency. He is not even 24, has played 5 (!) positions this year. Can you imagine what is in his head? He was only a part-time player at 2 spots last year. And THEN think about hitting?? Cut him some slack...You sure are picky lately. First wishing #6 NL RBI guy Russell have a better average, and now an "unncessarily fancy pick". Geez tough crowd!
it's going to be hard to take down scherzer.
kershaw is supposedly coming back soon, though he'll probably need a good amount of deep innings to match up with scherzer...probably too late at this point. tanner roark, bumgarner, and hendricks are probably going to steal some votes along with kershaw.
I absolutely love Javy's game, and I love the way Maddon changed the perception of him as a ballplayer, but I really wish he would just make the routine plays routinely. On the ground ball in the 9th, he made an unnecessarily fancy pick. He made the play, but tried the same thing last night and made an error.
How many wins does Kyle need for serious Cy Young consideration? Would 17 be enough if he leads the league in ERA? My goodness, what a season -- makes a Dartmouth alum proud.
hendricks WHIP drops to 0.98 over 159 innings after throwing 7ip 3h 1bb 4k, 0r/er
ERA down to 2.09 on the season.
I am pretty well fed up with the majority of home plate umps. Just terrible inconsistencies.
Oh shit forgot about that
Shark and Sczur right?
Yes, football player?- check.
