Coming Back From Shoulder Separation

By Dev K. Mishra, M.D., President, Sideline Sports Doc, Clinical Assistant Professor of Orthopedic Surgery, Stanford University

Key Points:

  • A “shoulder separation” is a different injury than a shoulder dislocation
  • The shoulder separation involves a sprain to the ligaments of a joint at the point of the shoulder near the end of the collarbone
  • We will often see these injuries when a player is tackled or falls to the ground on the point of the shoulder, with the arm at the player’s side
  • Most shoulder separations from sports injuries can successfully be treated without surgery

I’ve written recently about shoulder dislocation, a serious condition in which the ball portion of the shoulder (humerus) becomes completely dislodged from the socket. This week we’ll discuss a shoulder separation, another common shoulder injury. But first let’s clear up some terminology to avoid confusion.

A separated shoulder refers to an injury to the ligaments of the acromioclavicular joint (commonly known as the AC joint), which is the joint between the end of your collarbone and the upper part of your shoulder blade. It’s located near the point of the shoulder.

Most shoulder separations occur during some type of hard fall or contact, such as a quarterback being tackled on to his shoulder, or a cyclist falling and landing on his shoulder. When I see a hard fall to the ground I’ll be suspicious for either a shoulder separation or a broken collarbone if the athlete fell with the arm tucked in to the side, and I’m suspicious for a shoulder dislocation if the athlete fell on to the outstretched hand.

There are six types of shoulder separations. Types 1 and 2 are the most common ones we see in sports injuries and are treated without surgery. Type 3 injuries are also reasonably common, and most of these are treated without surgery (although there is some debate about early repair for the throwing shoulder of an elite athlete…). Types 4-6 are not seen very often in sports injuries and these will require surgery. I refer to these as “types” although some surgeons will call these “grades”.

  • Type 1 – The ligaments have a mild sprain without a tear.
  • Type 2 – The AC ligament tears, leading to a partial separation.
  • Type 3 – The AC ligament and other associated ligaments tear, leading to a complete separation.
  • Types 4-6 – These are complete separations, serious injuries often requiring urgent surgery. I have seen one type 4 separation in a D1 quarterback during my 23-year career.

Here are typical return to play times for the common types:

  • Type 1: You can usually return to play 2-3 weeks after the injury, depending on your sport and position. You should be comfortable, with full motion, normal strength, and ability to do sport specific motions. Treatment includes rest and anti-inflammatory medication.
  • Types 2 and 3: A Type 2 injury takes about 3-4 weeks to fully heal, and a type 3 injury takes about six to eight weeks to heal. We’ll almost always treat these without surgery, and we’ll use the same return to play criteria as indicated above for the Type 1 injury. If you’re in a collision sport (such as football) I’ll usually recommend you return to play with an AC joint pad to minimize the chance of another injury.

PITCH SMART RECOMMENDATIONS FOR YOUTH BASEBALL

By Dev K. Mishra, M.D., President, Sideline Sports Doc, Clinical Assistant Professor of Orthopedic Surgery, Stanford University

Key Points:

  • Young pitchers are at risk for arm injuries due to a number of factors, and pitching while fatigued is perhaps the biggest risk for injury
  • MLB’s Pitch Smart guidelines are designed to reduce injury risk while still allowing for the competitive development of the young player.
  • Parents, coaches, and league administrators would be wise to implement the Pitch Smart recommendations for their pitchers

As spring and summer baseball is ramping up, I’d like to remind our readers of a terrific Grant Lewisresource for the young pitcher- MLB’s Pitch Smart guidelines. I’ve written about pitch counts, the “100 inning rule”, and pitching injuries in several other blog posts but it is worth pointing out some of the reasons why we should revisit this topic. Pitch Smart is an effort by Major League Baseball to critically evaluate factors responsible for injury risk to young pitchers and then create guidelines to minimize that risk. Pitch Smart is partnered with many of the brightest minds in sports health for throwers and has produced a set of recommendations based on evidence and experience.

The result of their effort is a set of age appropriate recommendations designed to keep young pitchers as healthy as possible.

We’ve definitely made progress in recognizing and putting in place recommendations to reduce injury risk, but as the website points out we still have some work to do. For example, a survey of youth pitchers published in 2014 showed that of the pitchers responding to the survey many were engaging in behaviors that risk the health of their arms:

  • 45% pitched in a league without pitch counts or limits
  • 5% pitched on consecutive days
  • 4% pitched on multiple teams with overlapping seasons
  • 2% pitched competitive baseball for more than 8 months per year

Those published statistics are a few years old and hopefully we’ve made some progress in this area thanks to the efforts of Pitch Smart and others.

Take a look at the age-specific guidelines. They are divided into 5 age groups. For example, in the 15-18 year group which would cover most of our high school aged athletes some of the key recommendations are:

Players can begin using breaking pitches after developing consistent fastball and changeup

  • Do not exceed 100 combined innings pitched in any 12 month period
  • Take at least 4 months off from competitive pitching every year, including at least 2-3 continuous months off from all overhead throwing
  • Make sure to properly warm up before pitching
  • Set and follow pitch-count limits and required rest periods
  • Avoid playing for multiple teams at the same time
  • Avoid playing catcher while not pitching
  • Players should not pitch in multiple games on the same day
  • Make sure to follow guidelines across leagues, tournaments and showcases
  • Monitor for other signs of fatigue
  • A pitcher remaining in the game, but moving to a different position, can return as a pitcher anytime in the remainder of the game, but only once per game
  • No pitcher should appear in a game as a pitcher for three consecutive days, regardless of pitch counts

In my opinion, Pitch Smart’s recommendations are another example of much neededSideLineSportsDoc changes designed to keep young players playing longer and healthier. These are recommendations rather than rules, but if you are a league administrator I’d urge your league to have a close look at these recommendations and adopt them for your players.

DOES SPORT SPECIALIZATION GET YOU TO DIVISION 1 COLLEGE?

Key Points:

  • Sport specialization by adolescent and early teenage athletes is associated with a relatively high injury risk
  • One study of Division 1 athletes showed that only about 17% of athletes were “highly specialized” when they were in 9th grade, with about 41% “highly specialized” by 12th
  • Only a small number of the athletes felt that they were pressured by their parents to specialize

Young athletes, and high school aged athletes in particular feel a lot of pressure to specialize in one sport. The thought is that by specialization you have a better chance of playing in college or in the pros compared to those who don’t specialize. But is this actually true?

Here’s an interesting study that took a look at this question. It’s titled “High School Sport Specialization Patterns of Current Division 1 Athletes” and published in the journal Sports Health. The authors used a survey of current athletes at the University of Wisconsin- Madison to assess how specialized these high level collegians were in high school.

Three hundred forty three athletes participated, representing 9 sports at the university. They found that sport specialization increased throughout high school, with about 17% “highly specialized” as 9thgraders and about 41% highly specialized by 12th grade.

Specialization was more common in individual sports (such as tennis, swimming, golf, etc.) and specialization was much less common for football athletes. The most common reason the athletes gave for specialization was simply because they enjoyed that sport the most, and the second most common reason was the opportunity to earn a college scholarship. Only 10% cited parental pressure as the reason for specialization.

Whenever possible, I encourage my young athletic patients to participate in multiple sports. By the time they get to me it means they’ve already had an injury and I’m trying to reduce their chance of having another one. There’s ample scientific evidence that sport specialization is a key factor in negative outcomes such as injuries, psychological burnout, and poor body movement patterns. And on the other end we have plenty of evidence that participating in several physical activities can have real benefits (except when you play multiple sports at the same time!).

Overall I saw a lot to be encouraged by this study, at least if you happen to be an SideLineSportsDocathlete in Wisconsin! It’s believed by many that early sport specialization is driven by parental pressure but in this survey only a small percentage of the athletes said they were highly influenced by their parents. Most of the time the focus towards a single sport was driven by the athlete’s enjoyment of the sport. Most athletes who are talented enough to be recruited to play a Division 1 sport will eventually specialize in their sport, but at least for this group of athletes it didn’t appear that early specialization was necessary to become a Division 1 athlete.

IS THERE WEARABLE TECHNOLOGY IN THE YOUNG ATHLETE’S FUTURE?

By Dev K. Mishra, M.D., President, Sideline Sports Doc, Clinical Assistant Professor of Orthopedic Surgery, Stanford University

Key Points:

  • Wearable technology is very popular for monitoring steps, energy expenditure, and movement patterns.
  • The devices can generally be divided into step counters, accelerometers, GPS based devices, and physiologic measurement devices. Many systems combine several elements
  • The accelerometer and GPS based systems are likely to be useful for the young endurance sport athlete wishing to aim for peak performance
  • If you are using one of these devices for training it’s important to work with a coach experienced in interpreting the data for you

Wearable technology for adults is very popular, ranging from monitors like the FitBit, wearable technologyApple Watch, heart rate monitors, etc. In general I think there’s value for adults who are really interested in objective data to help them drive their fitness objectives and stay on track. But what about at the youth sports level? Are there technologies that could be useful to the young athlete?

This recently published article provides a nice overview of the available technologies when viewed from the sports medicine clinician’s perspective. I’ll review the categories of devices and provide some commentary on usefulness for the young athlete.

Step Counters

These devices are properly called “pedometers” and measure the number of steps taken by the individual. For adults the commonly used number is “10,000 steps a day for fitness”. There is some published evidence that pedometers help youngsters achieve a baseline level of fitness but we have no evidence that it will be of use to the young athlete. My conclusion for the young athlete: very limited value in using a step counter.

Accelerometers/Gyroscopes

These days many people carry around in their pockets a device that has some accelerometer functions: it’s called your smartphone. Beyond that, fitness specific accelerometers are widely available. This is where devices such as the FitBit, Nike Fuel Band, Jawbone UP, and others would reside. Accelerometers provide data that includes step counts but also much more such as heart rate, calorie usage, and sleep tracking. I’ve also seen several startup companies with wearable accelerometers that can track in real time and on the field movement patterns of the legs and arms. My conclusion for the young athlete: possibly useful for the elite athlete. When movement tracking of body parts becomes available I think this will have broader usage, such as looking at arm position in pitchers or knee mechanics with jumping.

GPS devices

Global positioning satellites are used with your smartphones to provide data to apps that give directions, like Google Maps. GPS wearable devices are also increasingly popular with sports applications, especially for endurance sport athletes and monitoring of entire teams. Wearable GPS monitoring is becoming the norm for adult elite collegiate and professional teams, and I’m seeing it more and more at the high school level too. Conclusion: useful for the young endurance athlete, likely to filter into youth team sports too.

Physiologic Sensors

These devices track body physiology measurements such as heart rate, body temperature, and respiration. Professional teams are using these devices frequently, and individual endurance sport athletes use these as well. These measurements are useful and likely helpful for the athlete looking to peak performance but one caution is that you need to have some knowledge in how to interpret the data. For professionals, this is the job of their training staff. For the young athlete particularly in endurance sports such as triathlon, cycling, or distance running the information could be very useful but it would be important to work with an experienced coach to help you interpret the data. My conclusion for the young athlete: possibly useful in limited circumstances.

Overall these devices have the potential to be incredibly helpful for the elite level young athlete, and could have benefits for the recreational athlete too. Many of them have a very strong “coolness” factor. We need more data in establishing baseline levels for the young athlete and for sure you should work with someone skilled in interpreting the data you receive. But they are here to stay and will likely undergo further refinements over the coming months.
