Acromioclavicular Joint Injury

acromioclavicular joint injury

What’s up ? This is THE stephane ANDRE. With my training, I’m interested in biomechanics to avoid injuries. I read « Sport Medicine Media Guide » and I learned some good stuff.

Acromioclavicular joint is a joint between the clavicle and the scapula. Acromion is a continuation of the scapular spine and hooks over anteriorly. It articulate with the clavicle (collar bone ) to form the acromioclavicular joint.

Problems types

The most common problems are arthritis, fracture and separation. Arthritis is characterized by a loss of joint’s cartilage. Arthritis of acromioclavicular joint is common with weight lifter, especially with bench press and a little less with shoulder press. When there is a problem with the rotator cuff, it’s possible that there is also acromioclavicular joint’s arthritis.

Acromioclavicular separation

acromioclavicular joint injury type grade

When there is an acromioclavicular joint separation, it means that the ligament that connects the acromion and clavicle is damaged and that the 2 structures don’t align properly. Separation’s state can be weak or severe, that is why there is a system of « grade » according to which ligament is torn and the severity of the tear.

Grade I Injury – This is the weakest damage and the acromioclavicular joint is still aligned.

Grade II Injury – This is an average damage. Ligaments are only stretched but not fully torn. In case of stress (physical effort), the acromioclavicular joint becomes painful and unstable.

Grade III Inury – This is a serious damage. Ligaments are completely torn and the collar bone is no longer attached to the scapula, which creates a visible deformity.

Treatment of acromioclavicular joint arthritis

If the rest, ice, medications and change of the training program (changing the exercises) don’t work, the next step is a shot of cortisone. A shot of cortisone in the joint may have calmed the pain and may be permanently swollen. As each individual is unique, the effects may vary and it’s possible that it doesn’t swell permanently.

If non-surgical methods fail, it’s possible to perform a surgical operation. The pain is localized at the bones end that make contact with each other and the goal of the operation is to remove some of the end of the clavicle. This ambulatory surgery can be done with a small incision of 1 inch (2.5 cm) long or with the arthroscopy technique with 2-3 incisions. The results and recovery of these 2 surgical techniques are about the same. Most patients have a full movement by 6 weeks and can return to do sport by 12 weeks.

Treatment for acromioclavicular separation

Separation can create very painful injuries, so the first thing to do is to decrease the pain. Hold the arm in a sling, put ice and pack the shoulder for 20-30 minutes every 2 hours as needed. Acetaminophen and non-steroidal anti-inflammatory medications can also help calm the pain.

When the pain begins to subside, it’s important to move the fingers, wrists and elbow (and eventually the shoulders) in order to avoid having stiff or « frozen » shoulder. The length of time needed to regain complete movement and function depends on the severity or injury’s grade.

Recovery from Grade I acromioclavicular separation usually takes 10-14 days while Grade III takes 6-8 weeks.

When surgery

Grade I and II separations require very rarely surgery. With a Grade III injury, after surgery, it’s possible to have full body physical activity with some restrictions.

General Stretching Of The Upper Body

stretching upper body

What’s up ? This is THE stephane ANDRE ! I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Stand with your feet a little wider than your pelvis width and you back is straight :

  • Hold your ams vertically with your hands clasped and your fingers crossed. Your palms directed upwards :

  • Inhale to inflate your lungs to the maximum and stretch your intercostal muscles. Push your palms up keeping your back and head upright.

  • Exhale slowly by relaxing and starts again.

This stretching exercise stretches intercostal, rectus abdominis, latissimus dorsi, teres major, triceps. When you incline your torso laterally, you stretch more your external oblique and internal oblique, quadratus lumborum and the internal and medium part of your erectors spinae.

stretching upper body lateral

Note

This stretch is great for relaxing the body after a training with heavyweights like leg press, squat, deadlift because the ribcage and spine have been compressed.

This movement may occasionally replace or supplement the stretching at the bar  to rebalance the pressure and tensions of the intervertebral joints.

Deadlift Correctly (Part 3)

deadlift

If you didn’t read the first parts, click Part 1 and Part 2 

I read a Nerd Fitness article and I learned good stuff.

Grip the barbell

deadlift grip

The strength of the grip is an important part of the deadlift. There are 2 types of grip:

  • Overhand grip => The palms of your hands are towards your body (pronated grip).

  • Over-under ou mixed grip => One palm of your hand is toward your body and the other towards the outside (one hand with a pronated grip and the other with a supinated grip).

  • Hook grip => Your thumb is under your fingers

For beginners, the double overhand grip is the best to have a safe grip.

Use the mixed grip when you have more experience and you lift heavy because there are disadvantages. Stress on the shoulders is uneven and can create problems or injuries in the biceps whose palm is outside. As the stress on the shoulders is uneven, it’s easier to lift heavy weights.

When you begin deadlift, your grip’s strength is powerful enough to lift the barbell because your back’s strength is correct. The day of your back’s strength is more powerful than your grip’s strength (your hands slips slowly), that’s when you need to think about improving your grip.

If you don’t like the mixed grip, you can use the hook grip.

Wrist straps

Straps can help you lift heavier because your grip is assisted by a strap that is wrapped to the barbell and is hooked to your wrist.

I advise you to use wrist straps only when you lift very very heavy. This is not a thing to use all the time otherwise you’ll lose the natural strength of your grip.

Gloves

The truth is that the gloves don’t improve the grip. Gloves create a space between your hands and the barbell, this increases the diameter of the barbell and make the barbell harder to hold. Gloves prevent you from having a secure grip, I advise you to use them only if you have ripped callus to your hands.

With this video , you’ll learn to take care of your hands to avoid having this type of injury.

Belt

Many people in gyms use the belt in the wrong way, but you’re a smart one. The belt is useful only when you’re lifting very heavy weights and it’s not only for your lumbar. With this article , you’ll learn how to use the belt in an effective way.

Note

Use a mixed grip and a belt isn’t necessary to lift very heavy. Watch this video of Anthony Mychan  who do a deadlift at 249.47kg (550lbs) at a Nerd Fitness Camp with a double overhand with no belt.

Common mistakes

common mistakes

Rounded back

Having the back rounded throughout the movement may cause injuries. It’s necessary to have your spine in a neutral position.

Note => there are some powerlifters that purposefully round theirs upper back to decrease the range of motion, but this is a sport specific move, still a fault, and something you should not consider as a beginner.

Head raised and look up

To have a raised head create a hyperextension to your neck. This can cause injuries. Keep your head in a neutral position like your spine.

Hyperextending at the top

In fitness competitions, exaggerate the top of the deadlift has become popular for quickly show the judges that hip and knees locking is done.

Use the squat position

Deadlift is not squat. Deadlift doesn’t have the same start and end position as the squat. Deadlift is a different movement than squat.

Barbell makes a forward movement

It’s necessary that the barbell stays above your shoe’s laces and the barbell needs to be lifted vertically all along your body.

Barbell’s movements towards the front are to be avoided.

Your torso rises after your butt

We call it the « stripper deadlift ».

It’s important that your torso guides the movement and that your body moves in the same rhythm upwards.

Bend your arms

Often people bend their arms to lift the barbell more quickly. Unfortunately, this is a bad tactic because this can tear biceps muscle. Keep your arms straight during the movement.

The Reasons For An Asymmetric Body (Part 1)

asymmetircal body

I watched a Jamcore DZ’s video  and I learned good stuff.

When I look in the mirror, I see that my right biceps is bigger than my left biceps. And I also see that my left calf is bigger than my right calf. I think you too, you have weak points and an asymmetrical body like me.

I tried several technique to clear the weak point of my left biceps by doing more reps or lifting heavier with my left arm. But it didn’t work as I thought and I realized that there were even more factors that caused my asymmetrical body.

You have to know that there are real weak points and false weak points. And yes, there are 2 type of weak points.

Past sports

sports

These are the sports that you have done regularly before you train seriously at the gym. For exemple, I played soccer for 2-3 years so I developed a lot of my legs and calves. I have been doing karate, kung-fu and taekwondo for years (I have more than 15 years of martial art) so I developed a lot my back, my arms, chest and my abs. My past sports allows me to develop all these muscles (calves, legs, back, arms, chest and abs) even more easily.

Now I’m going to tell you about the difference between a real weak points and a false weak points. In my case, I have nice abs, nice, chest. My arms are correct (I have one arm bigger that the other) and my legs are correct (I have one leg bigger than the other).

For example, a soccer player or a cyclist will use his/her legs and calves more often. A boxer will use his/her arms, back and abs more often. This shows that the past sports is important in muscle development because people developed more rapidly the upper body’s muscles rather the lower body muscles or the reverse.

So don’t worry because absolutely everyone has an asymmetric body (if you know a person who has a 100 % symmetrical body, attention, it’s a robot).

Genetic

genetic

It’s the moment to go to the higher level. Now, you understood that there are people who can easily develop the upper body’s muscles rather that the lower body’s muscles or the reverse. In both case, there is the same problem : an asymmetry.

We’re human beings, we are not perfect and that is normal. Professional bodybuilders also have an asymmetric body like you. It’s for everyone like that. When we look at the mirror, we have a more developed part than the other.

Here are the causes.

Bone

bone

Because of your bones, there is one side of you body that can lift easily heavier weights that the other. So the side muscles that can lift easily heavier develop faster.

A) clavicle length

We all have a longer clavicle than the other. Take you time, check the length of your clavicles, you will be surprised. When the clavicle is longer, this affects the leverage when you lift weights. This means that it boost your strength and your muscular growth.

But, there is a solution to avoid that there is a big difference between the 2 sides. It’s learning to isolate and feel your muscle. I use a technique called « magic touch ». Before doing a set, I touch with my fingers the muscle that I have to work. This allows me to be focus and stay focus on muscle sensations. This is to create the connection between my brain and my muscle.

This is why it’s important to take light weights to learn how to perform a movement to learn the muscles sensations. For example, bench press. There are people who use too much shoulders when the arms are straight. Bench press is an exercice to work mainly chest and not shoulders. So pay attention to your muscles sensation when you to an exercise and adjust.

B) Short and long muscles

This is really a genetic case. There are people with short muscles or long muscle. Take as an example a short biceps and a long biceps.

A short biceps responds slowly to training because the muscles is less close to insertion with the joint.

A long biceps respond quickly to the training because the muscle is closer to insertion with the joint.

As you can see, there are some similarities with the clavicle’s length. When the muscle is long, it’s easier to develop the muscle.

This is something you can’t change and doing an operation to lengthen your muscle is useless. It’s your genetics that decides whether your muscles are short or long.

dorian yates

Wait, it’s not over yet, there’s still plenty of other things in the genetics that influence muscle development. In your training, you can use several techniques to stimulate your muscle fibers like « High Intensity Training » . Dorian Yates (6x Mr. Olympia), used this technique during his career as a professional bodybuilder. This technique stimulates muscle fibers even more that hypertrophy .

There is also nerve genetics. It’s the ability to isolate and feel the muscle you’re working on. It’s an ability that improves only with experience and time.

Here is the end of the Part 1. The Part 2 comes soon.

Stretching Of Deltoids Anterior

stretching of deltoids anterior beams

I read a Frederic Delavier’s book « Strength Training Anatomy » and there is good stuff.

Standing legs spreads to shoulers width. Your arms stretched behind your back with your fingers crossed. Push your arms as far back as possible and raise your arms slowly. Pull out your torso and try to touch your torso with your chin.

Keep this position for 10-20 seconds.

This exercice mainly stretches deltoid anterior beams, pectoralis major (chest) and brachii biceps. This exercice stretches a little bit the brachial, brachio-radial and all wrist’s muscles extensor.
