Background:Restoration of proximal humeral anatomy (RPHA) after total shoulder arthroplasty (TSA) has been shown to result in better clinical outcomes than is the case in non-anatomical humeral reconstruction. Preoperative virtual planning has mainly focused on glenoid component placement. Such planning also has the potential to improve anatomical positioning of the humeral head by more accurately guiding of the humeral head cut, and selection of anatomical humeral component sizing. Hypothesis of the study: The use of preoperative 3D planning helps to reliably achieve RPHA after stemless TSA.

Methods:One hundred consecutive stemless TSA (67 males, 51 right shoulder, mean age of 62 9.4 years) were radiographically assessed using pre- and postoperative standardized AP radiographs. The RPHA was measured with the so-called circle method described by Youderian et al. We measured deviation from the premorbid center of rotation (COR), and more than 3mm was considered as minimal clinical important difference. Additionally, pre- and postoperative humeral head diameter (HHD), head neck angle (HNA) and humeral head height (HHH) were measured to assess additional geometrical risk factors for poor RPHA.

Results:The mean distance from of the premorbid to the implanted head COR was 4.3mm 3.1mm. Thirty five shoulders (35%) showed a deviation of less than 3mm (mean 1.9, 1.1) and 65 shoulders (65%) a deviation of 3mm (mean 8.0 3.7). Overstuffing was the main reason for poor RPHA (88%). The level of the humeral head cut was responsible for overstuffing in the 46 of the 57 overstuffed cases. The preoperative HHD, HHH and the HNA were significantly larger, higher and more in valgus angulation in the group with accurate compared to the group with poor RPHA (HHD of 61.1mm 4.4 vs 55.9 6.6, p<0.001; HHH 8.62.2 vs 7.62.6 p=0.026, varus angulation of 134.7 6.4 vs. 131.0 7.91, p=0.010).

Conclusion:Restoration of proximal humeral anatomy after stemless TSA using CT-based 3D planning was not precise. A poorly performed humeral head cut was the main reason for overstuffing which was seen in 88% of the cases with inaccurate RPHA. Preoperative small HHD, low HHH and varus angulated HNA are risk factors for poor RPHA after stemless TSA.

Clinical significance:While Preoperative CT-based 3-D planning gives insight into the proximal humeral anatomy, execution of this insight through visual based surgery without guides or navigation, does not appear to increase accuracy of RPHA.

Level of evidence:Level IV; Case Series; Treatment Study.

Keywords:CT based 3D planning of total shoulder arthroplasty; Humeral head cut; Humeral head implant size; Restoration of proximal humerus anatomy; Total shoulder arthroplasty; preoperative virtual planning.

Most kinesiology graduates go on to have careers in exercise, health or education.Patrick McMurraywenton to open acclaimed sea food restaurants and break Guinness World Records for oyster shucking and credits his University of Toronto education, no less.

Born into a family of teachers, McMurray planned to become a teacher after completing his bachelors degree in physical health and education at U of T in 1993.

Yet, McMurray says his undergraduate education was quietly preparing him for a career in the food industry all along.

During my time at the university, I was the social director, organizing monthly pubs and social gatherings, and helping out with frosh weeks, he says. I was also working in restaurants as a server during that time to help pay for school.

McMurray started his own restaurant called Starfish in 2001 and six months later won the Canadian shucking championship a third time. Next, he was off to Ireland to compete in the world championship, taking his new blade and training regimen with him.

Going from a Canadian championship to a world championship is like switching from a sprint to a long distance race. says McMurray. You have to use a different approach.

The Canadian championship requires contestants to shuck 18 oysters. At the world championships, contestants have to shuck 30 Irish native oysters, which are a different species and are technically more difficult to open. McMurray used his university education to help him train. Leaning on the lessons he learned in his biomechanics and ergonomics classes, he designed an ergo-dynamic knife, which gave him a better grip and more leverage. He also developed a technique that would help him open the oysters more efficiently.

The difficulty of shucking an oyster comes from it being hard on the outside and soft on the inside, he explains. You have to sever the muscle that holds the two shells together and serve the oyster without cutting the meat, so the competitions are a combination of speed and dexterity.

You can save a lot of time by training your hands to do different things.

Murray came up with the idea ofserving his customers plates of 30 oysters for $35 while they timed him shucking oysters on a table the same height as the competition table. He went on to win the Galway World Championships that year, the first Canadian to accomplish the feat. When he returned home to Canada, he was invited on Christine Cushings show on Food TV.

I thought Id make an attempt at the Guinness world record, set at 27 oysters in one minute, a perfect time frame for TV, McMurray says. I brought 40 Oysters, opened 33 in 60 seconds, and after sending in the video and letters, was awarded my first Guinness world record.

Ever since, McMurray has received calls from around the world asking him to attempt tobreak his own record which he did in 2007 inBeijing, where he shucked 38 oysters per minute.Then, in2017, he went head to head with Gordon Ramsay on The F-Word Live show, setting the new record of 39 oysters per minute. His Guinness world record now stands at 1,114 oysters in one hour.

Oysters have taken McMurray around the world, across Canada and throughout the U.S., Europe and Asia.

Travelling around the globe has shown me that oyster culture is found wherever ocean touches land, McMurray says.

In 2007, he published his first book on oysters, calledConsider the Oyster:a Shuckers Field Guide, in which he wrote about the global nature of oysters and created the oyster tasting wheel. In 2018, he published a second edition calledThe Oyster Companion, which includes recipes and more stories.

Oysters are a rare food that can take you back to an exact location and memory, he says. Thats because when the muscle closes, it captures sea water that it uses as its lifeblood. That little drop of ocean water has the flavour of the region its been plucked from, so I can open up an oyster from Ireland here in Toronto and smell the sea breeze in western Ireland.

Thats why I always tell people to first smell the oyster, then chew it.

McMurray is often invited to speak at special events, judge shucking contests and make TV appearances, most memorably on Martha Stewarts TV show, where he showed her, Snoop Dogg and Wanda Sykes how to shuck oysters and spoke about oyster etiquette, such as choosing the right sauce.

If you look at Tabasco sauce, thats great for someone from Louisiana, but if youre in Paris, why are you using a Louisiana sauce on a Parisian order of French oysters? Regional sauces would be more appropriate, he says. On the other hand, the Olympia oyster should be eaten without sauce. Its the size of a loonie and it takes five years to grow it and it virtually melts on the palette. Its so small, but its the most complex of all oysters.

When hes not teaching celebrities about oysters, McMurray teaches a culinary and hospitality class at Centennial College, having finally come full circle from his days at U of T when he planned to become a teacher.

When I teach my class about oysters, I talk about the different species, the anatomy of the oyster and how to open it. I learned all about muscles in my anatomy class at U of T, he says.

He saysthere is no better food source for protein than oysters. Theyre low on fat, contain Omega 3 and Omega 6, zinc, selenium and vitamin D. And, he says, they are among the most sustainable foods to grow, with the ocean doing most of the work.

Eat an oyster, save an ocean, says McMurray. Theyre good for you and the environment.

His words of advice for new students starting their education in the most unusual of times? Enjoy it.

You never know where you will end up, but know that youll always be able to use what youre learning and apply it perhaps in different ways than originally intended, says McMurray.And, follow your passion. My passion turned out to be food, but I used so much of what I learned in school about nutrition, anatomy and biomechanics in my career.

Surprises abound in the new IDTechEx Research report, "Supercapacitor Markets, Technology Roadmap, Opportunities 2021-2041". In 2010, there were no Chinese manufacturers in the top ten supercapacitor manufacturers. In 2020, 40% of them are Chinese. This has been achieved by world-class R&D, being in one of the largest markets globally, strong investment and government support including protective trading. However, China is not leading in capacitor-supercapacitor hybrids where the USA saw a $7 million follow on order recently.

An exception to the commoditisation is small supercapacitors in the form of battery-supercapacitor hybrids BSH, aerospace and military ones working at 150C, capacitor-supercapacitor hybrids beating tantalum electrolytics on ripple and one fifth to one tenth of the size and weight and ones in odd formats such as to go in a watch or smart card. Those working at 85C, -40C and 3V as single cells are less common and in demand.

Several companies declare their supercapacitors to be "graphene" as a badge of honour. It can mean non-flammable, relatively non-toxic, no use of the volatile, toxic carcinogen acetonitrile, valuably improved series resistance, better voltage and energy density in a pure EDLC - all good things justifying higher price.

Raghu Das predicts, "Acquisitions and mergers will continue. One billion dollar supercapacitor businesses may be created by 2045. If the addressable markets we have analysed are strongly penetrated, then it will be much earlier. Given past disappointments, our upside forecast currently stands at $7 billion in 2041."

Editors note: How did Ohio State football become a Buckeye Nation of true believers? In a 14-part series, we explore aspects that shaped OSUs evolution from Saturday afternoon diversion to near-religious experience. Today: Chase

Not even two Heisman Trophies can bookend the regret that slides off the shelf of Archie Griffins most painful Pasadena memory, when undefeated Ohio State lost to underdog UCLA in the 1976 Rose Bowl, costing the Buckeyes a national championship.

Thats the one that haunts me, Griffin said, grimacing more from the recollection of that 23-10 loss than from the sore back that now hampers his golf game.

The Buckeyes were ranked No. 1 in both the Associated Press and United Press International polls, had defeated the Bruins 41-20 in the Los Angeles Coliseum earlier in the season and entered the New Years Day game as two-touchdown favorites.

Yet despite coming up short again Griffin finished 1-3 in Rose Bowls, with two lost chances at national titles the former tailback would not describe 1975 as a failed season just because the Buckeyes were not voted No. 1.

It cant be national championship or bust, he said.

It cant? Try telling that to Ohio State fans too young to recall when a successful season could be defined by a win over Michigan and playing in the Rose Bowl. These days, anything short of a College Football Playoff appearance, culminating in a national championship, leaves many fans, players and coaches feeling frustrated.

Before the Big Ten reinstituted football on Wednesday, Ohio State coach Ryan Day tweeted we still have an opportunity to give our young men what they have worked so hard for: a chance to safely compete for a national championship this fall.

Woody Hayes did not think that way. The former OSU coach considered a national championship the outcome of a special season not the goal. Win the Big Ten and Rose Bowl and the chances of being voted poll champions were pretty good.

But there were no guarantees, which explains why Hayes and the next two Buckeyes coaches, Earle Bruce and John Cooper, focused their attention more on winning the conference than winning a national championship that was decided by media and coaches poll voters. During Hayes time, and before, voting to determine the national champion took place before the bowl games were played.

As Griffin explained it, You could win your bowl game and might win the national championship, but it in the end it was still up to the voters.

Cooper learned that the hard way in 1996 the penultimate season before the Bowl Championship Series began when the Buckeyes lone blemish was a 13-9 loss to Michigan in The Slip game. Ohio State dropped from No. 2 to No. 4 in the polls, then defeated No. 2-ranked Arizona State 20-17 in the Rose Bowl.

Cooper hoped voters would bump the Buckeyes to No. 1, but OSU finished No. 2 to Florida after the Gators defeated No. 1 Florida State 52-20 in the Sugar Bowl.

Im envious of the (playoff) system, the 83-year-old Cooper said. I had a couple teams that, Im not saying they would have won it but they would have played for the national championship.

Cooper admitted, however, that such wishful thinking fails to consider context and a changing win-at-all-cost culture.

Times have changed, he said. The goal back then seemed like it was win your games, beat Michigan and go to the Rose Bowl. It used to be you win the Big Ten, youre going to play in the Rose Bowl.

I coached at Oregon State and UCLA, and even out there the goal was to go to the Rose Bowl. Bowls were a reward for a good season. Later on, it became you had to win the Rose Bowl.

The BCS changed everything when it arrived in 1998, pitting No. 1 vs. No. 2 in a championship game that removed some subjectivity from the equation. Schools still had to be voted into the top two spots, but the title was decided on the field.

By the time Ben Hartsock arrived at Ohio State, in 1999, the tight end already had put most of the Rose Bowl mystique in his rearview mirror. He grew up listening to his father rave about The Granddaddy of them All, but as a player, Hartsock knew there were bigger fish to fry.

The importance of the Rose Bowl felt to me like something my dad focused on, Hartsock said. I knew how big it was because I was raised in a house that taught that curriculum, but I transitioned away from it.

When Jim Tressel arrived at Ohio State in 2001, he immediately replaced Rose Bowl with national title.

When Tressel came in, the main focus was Michigan. It starts with beating Michigan, then winning the Big Ten and the national title, Hartsock said. And winning the Big Ten was the only way to get to the national title. You could argue thats not the case today.

A team now can fail to win its regular-season conference championship and still win a national title, as Alabama did in 2011 (BCS) and 2017 (College Football Playoff). The playoff selection committee emphasizes that its only mission is to choose the four best teams.

Left unsaid is the reality that any team outside the top four and any bowl outside the two semifinals and championship game becomes an afterthought.

Its now all about making the playoff. Ohio State coach Urban Meyer in 2014 even gave a name to the quest: The Chase.

That doesnt mean coaches minimize conference championships. Meyer stressed in 2014 that we wake up every day to compete for championships in November. But those conference titles are more a means to an end than the ultimate goal. In Ohio States case, the first job is to win the Big Ten East Division, which gets you into the conference championship game, then win in Indianapolis to hopefully earn a playoff berth.

As for the players, todays Buckeyes are more aware of the drive for a national championship than their predecessors. With 24/7 sports media, tuning out the playoff noise is impossible.

Of course, some things never change, no matter the ultimate goal.

In early August, when the Big Ten was adjusting its schedules to eliminate nonconference games during the coronavirus pandemic, OSU quarterback Justin Fields tweeted, I dont care when we play Michigan, I just want to play them and beat the brakes off them.

ST. PAUL, Minn.(BUSINESS WIRE)Spineology Inc., an innovator in anatomy-conserving surgery, is excited to announce the FDA grant of its proprietary Spineology Interbody Fusion System, now called the OptiMesh Expandable Interbody Fusion System. The grant follows the successful completion of the SCOUT (Spineology Clinical Outcomes Trial) Investigational Device Exemption (IDE) trial. OptiMesh is a unique mesh device that expands in three dimensions, enabling surgeons to perform interbody fusion procedures through the smallest access in the spine industry.

The SCOUT IDE trial outcomes data was presented at the Society for Minimally Invasive Spine Surgery (SMISS) Annual Meeting in November 2019, by the trials lead investigator, John Chi, M.D., M.P.H. Dr. Chi is Director of Neurosurgical Oncology at Brigham and Womens Hospital in Boston, Massachusetts, and Associate Professor of Neurosurgery at Harvard Medical School. Dr. Chi and his co-authors reported:

We have found this innovative, minimally invasive device to be a safe and effective option for lumbar interbody fusion procedures, said Dr. Chi. The outcomes, including high fusion rates, improved function, reduced pain and high satisfaction rates, are very favorable. Additionally, the minimal exposure requirements yielded an exceptional safety profile.

Spineology is preparing for a Q1 2021 launch of the OptiLIF procedure utilizing the OptiMesh device. This procedure enables enhanced recovery and exceptional efficiency, and its outcomes are supported by prospective FDA IDE clinical data.

OptiLIF is the least invasive lumbar fusion procedure that I can do, said Dr. Stephane Lavoie of DeLand, Florida, an investigator in the SCOUT study. The unique OptiMesh implant can be inserted through a one-centimeter incision and then expanded to restore anatomy, which provides neural decompression and optimally conforms to a patients endplates. As a result, patients recover quickly, and the impact to procedure efficiency is significant. OptiLIF will have a major impact on the standard of care related to low back and leg pain.

The FDA De Novo grant of the OptiMesh Expandable Interbody Fusion System opens the door to commercialization of Spineologys OptiLIF procedure, which supports Spineologys anatomy-conserving product strategy.

Kirby is one of Nintendo's most adorable characters, as well as one of its most bizarre. Here's what you should know about the pink puffball's body.

Nintendo's lovable pink fluffball has been around for over 20 years since his debut in Kirby's Dream Land on the Game Boy. Since then, Kirby has found himself in many adventures that have forced him to adapt to various situations, from getting turned to yarn to riding a giant robot through space, and that's not even getting into his signature copy ability,which changesboth his appearance and capabilities in battle.

Throughout Kirby's storied history, the hero of Pop Star has gone through many changes from great to small to incredibly strange, but always maintaining that adorably iconic silhouette. Here is a quick look at the various weird aspects of Kirby's appearance and biology and how it has changed from conception until now.

Despite being powerful enough to eliminate gigantic magic space monsters and inhale black holes, Kirby's only officially listed height places himat under a single foot. This little factoid comes froma character profile promoting the release of Kirby 64: The Crystal Shardsin the Japanese-only Nintendo Online Magazine.

This listing should be taken with a grain of salt, as in the same game, it's shown Kirby actually reaches about half the height of his friend Adeleine, who is, for all intents and purposes, a normal human girl (albeit one that can paint pictures that come to life). Super Smash Bros. fans should also be awarethatheight hardly matter when it comes to Nintendo characters, as Captain Olimar from Pikminis barely the size of a quarter in his own game.

Considering how rubbery and pliable the little guy is, this should be a given, but it has been officially confirmed that Kirby has no skeletonand no teeth. How Kirby manages to hold himself up and maintain his shape is still a mystery.

The animeKirby: Right Back At Ya! (simply titled Kirby of the Stars in Japan) had an episode titled "A Dental Dilemma" where a dentist monster created by Nightmare Enterprises tries to find teeth in Kirby's mouth to clean, only to find he has none. Not that he needed teeth to begin with, since he vacuums up mountain-sized cakes and monsters on a daily basis.
