Sublime Projection

Adam Frank is an artist who uses new and old technologies to manipulate light in surprisingly simple and sublime ways. He just recently turned his attention toward objects scaled for the home (you might have seen Lumen, his series of shadow-projecting oil candles).

His latest design (finished just a few days ago, he tells me) is a small light that draws the outline of a window and not-so-distant trees on your presumably windowless wall.

A lovely detail: The movement of air caused by the heat of the bulb makes the "branches" tremble from time to time, as though they are being blown by a gentle, arbitrary breeze.

Pedro's Prognosis:  A Q&A with Dr. Christopher Mazoué

Pedro_card_4

A younger, healthier Pedro Martinez marvels at his own amazing stats

Baseball stat-heads make a convincing case that the Pedro Martinez of 1997-2000 was the greatest pitcher in the game's history.  Against the supercharged offenses of the steroids era, Pedro dominated the way Bob Gibson had during modern-era baseball's weakest offensive phase, the 1960s.

In late 2001, Pedro was diagnosed with a partially torn rotator cuff.  Pitchers in these circumstances typically opt either to undergo surgery or to retire, but Pedro instead remade his delivery.  Formerly an over-the-top power pitcher, he transformed himself into a sidearm finesse pitcher--this to protect his shoulder.  The guy who threw 98 mph would never return, but his replacement, throwing 88 to 93 mph, continued to dominate Major League hitters for almost five more years.

Last October 5th, in pain and barely able to reach the mid 80s, Pedro finally underwent surgery on his torn rotator cuff.  In mid or late summer he will return to the Mets--but as what kind of pitcher?  What is the nature of the injury he suffered, how is it treated, and what is his prognosis?

For answers to these questions, GQ turned to Dr. Christopher Mazoué, a South Carolina-based orthopedic surgeon and a former protégé of the legendary Dr. James Andrews at the renowned American Sports Medicine Institute.

What is the rotator cuff, and what causes it to tear?

The shoulder joint, being a ball-and-socket joint, is inherently unstable.  The rotator cuff is a set of four muscles that surrounds the shoulder joint.  One of its functions is to provide stability.  Its other function is to produce motion of the shoulder.  We're still in the process of determining what exactly causes rotator-cuff tears, but in baseball players the primary cause is the tremendous stress put on the rotator-cuff muscles and the tendons attached to those muscles when they're throwing the baseball.

In a baseball pitcher, what are the symptoms of a rotator-cuff tear?

Classically we've referred to it as "dead-arm syndrome," basically meaning that you begin to lose velocity and lose control when you're pitching.  Pain is the most common symptom, however.  Incidentally, a very large majority of Major League Baseball pitchers have at least a partial tear.  It doesn't necessarily affect their performance.  You can have an asymptomatic pitcher with a partial-thickness rotator-cuff tear.

How is a rotator-cuff tear diagnosed?

An MRI with dye injected into the joint--it's called an MRI arthrogram--is becoming the study of choice to detect rotator-cuff tears.  We see two different types of injury:  partial-thickness tears and full-thickness tears.  Usually we will debride, or clean up, the torn part of the tendon.  And we make a determination on how deeply the rotator cuff is torn and where it's torn.  If its depth is greater than fifty percent, oftentimes we will repair the tendon.  If it's less than fifty percent, we will commonly just clean up the tendon and then treat any other injuries within the shoulder that we find.

How is a rotator-cuff tear repaired?

It's usually an arthroscopic procedure.  We make several small incisions and then place a small camera within the shoulder joint, then stitch together the tear using one of two techniques:  Either we convert a partial-thickness tear into a full-thickness tear, then anchor it in the bone with sutures, or we keep the attachments of the rotator cuff in place and just repair it through the tendon.

It sounds relatively non-invasive.  Why are eight months of rehab required?

Over time, the pitcher has developed significant weakness not only in the rotator cuff but also in the surrounding muscles of the shoulder.  The surgery further worsens that weakness.  So the pitcher needs to allow for the healing of not only the rotator cuff, but also the surrounding soft tissues.  And then we want to reintroduce stresses to the shoulder slowly, over time, to allow the tissues around the shoulder to adapt.

Is there any merit to the claim of many scouts and coaches to the effect that pitchers with smaller frames, like Pedro--who's 5'11" and in his prime weighed less than 170 pounds--are particularly susceptible to injuries like this?

Common sense would suggest that there is a relationship between body size, the ability to throw at a high velocity, and the risk of injury, but there's not much scientific evidence for this.

Many post-operative Tommy John-surgery pitchers return throwing at least as hard as they've ever done, sometimes even harder.  Do we see a similar phenomenon with post-rotator-cuff surgery patients?

Yeah, the interesting thing about that is oftentimes the reason that they're throwing harder after surgery is because prior to surgery they weren't throwing as hard as they could--because they were injured.  Pedro Martinez traditionally throws 93 to 96 mph, but in the last couple years that's dropped down to 88, 90, because his injured rotator cuff wouldn't allow him to generate the forces to throw the ball as hard.  Once he recuperates from this injury, assuming he heals it correctly and he gets his strength back, there's a good chance that he'll regain the strength required to throw 95 mph.

Pedro changed his mechanics after he was first diagnosed with a partial-thickness tear back in late 2001.  To that point he'd thrown over the top; thenceforth he threw sidearm.  In his prime, throwing over the top, he'd regularly touched 97, 98 mph.  Is there a basis for thinking he might be able to reinstate that powerful over-the-top delivery?

He may not want to do that, because that seemingly produced a lot of discomfort in his shoulder.  It will be interesting to find out where he's going to position his shoulder when he returns to pitching.

It's been reported that pitchers who've had rotator-cuff surgery typically return to action after about eight months.  Pedro had his surgery on October 5th, which would suggest he'd be back no sooner than early June.  Is there a chance he might return sooner than that?

Oh, I think eight months is a short period of time.  A non-pitcher can get back sooner than that, but I would say that typically it takes eight months to a year, at least.

So it's possible we may not see Pedro at full strength until 2008?

Yeah, I think if he gets back in August or September, which they're predicting, it might be limited duty.  He may get back to full strength, but it's more likely that he won't have the durability and strength to return to the rotation until 2008.

What sort of durability do we see in guys who've had this surgery?  Will Pedro need to be mindful of this injury through the remainder of his career?

Well, we do know that he has injury already in his shoulder, and the tissues in the shoulder have a certain lifespan.  There's a very good chance that he will have a number of years left, assuming that he does well with his postoperative recovery.  But it's hard to say how many.

The Demon Pitch

Daisuke Matsuzaka's advent into the Major Leagues has precipitated a flood of articles about the gyroball, the mysterious pitch he may, or may not, have mastered. On one side, authorities such as physics prof and baseball fan Alan M. Nathan doubt the pitch's existence, saying that its characteristic football-spiral spin won't produce the trajectory that's claimed for it. (Some say it moves like a screwball, others like an exaggerated slider, still others like a sinker.) On the other, two Japanese engineers have penned a gyroball primer--its title has been translated variously as THE TRUTH ABOUT THE SUPERNATURAL PITCH and THE SECRET OF THE DEMON PITCH--in which they lay out the case for what would be the first new baseball pitch since the split-fingered fastball.

This four-part article, from bigempire.com, stands as the most complete and illuminating look at the gyroball I've yet seen, in no small part because its author speaks Japanese and can interview the key figures in the story. Among other things, he visits a Tokyo training facility, the futuristically named Beta Endorphin, that offers one-on-one gyroball instruction for the equivalent of $104 per hour.

The piece includes a movie, reproduced below, that models the "wake," or airflow, created by a two-seam gyroball. The wake is significant here, the Japanese authors believe, because it strongly resembles a forkball's, with one difference: It's considerably narrower--which is to say, it encounters less air resistance. Their conclusion: When it's thrown just right, the gyroball should sink like a forkball, but travel at a much greater velocity. It does sound like a difficult pitch to hit, if it really exists.

One other thread of interest on this subject: The musings of Kyle Boddy, an ex-college pitcher in Seattle who's trying to learn how to throw the gyroball. Boddy says that the pitch is for real, and he writes lucidly about trying to master it.

Foiled Design

Sometimes, design simply doesn't work. Something goes awry between the time the drawings leave the designer's hands and the product finds its way onto store shelves.

Case in point: Polder's Z-Series Ironing Board, which won a "Design Distinction" award in I.D. magazine's annual design review last year and is pretty much the only stylish ironing board money can buy. It was designed by Scott Henderson, who's done great work for OXO (check out his dust pan and brush) and Mint.

Besides its sleek looks, it boasts a fair number of functional enhancements. Forgoing creaky tubular legs for something L-shaped and flat gives the board an ultra-slim profile when folded and makes it easy to hang on a wall. Plus, it has a built-in outlet right under the board and a smartly placed rail for hanging your newly pressed shirts.

That said, the ironing board itself is ridiculously wobbly. Even when I stuffed about three inches of folded cardboard under one of the feet, it was still completely unstable.

I talked to Henderson briefly about it. The prototype he'd submitted to Polder didn't have that problem, he said, and he wasn't involved in how the product was ultimately realized. A rep at Polder told me that they're coming out with a new version of the ironing board with stabilizing rubber feet next month (Henderson wasn't consulted on the fix). If you were thinking of buying one, hold off until the new version comes out.

Similarly, I'd had my eye on Jasper Morrison's gorgeous kitchen appliances for Rowenta—a coffee maker, toaster, and water kettle—until Morrison mentioned to me that people had been e-mailing his office to complain that the electronics in the appliances were malfunctioning.

Morrison, of course, has no control over the electrical components inside these products, but he's since taken a proactive approach by putting a warning on his Web site: "Reports received on malfunctioning products. Buyers beware!" (The warnings are in red type and are the only use of color on his ultra-minimal site. They also have the site's only exclamation points, as well.)

As frustrating as it is for us consumers, I know these problems frustrate designers as well. It's a loss for everyone when a great design is just a step or two away from being realized.
