What is AC joint separation? Do I need surgery for this?

 Recently a friend of mine had a falling accident in a playground and was Diagnosed as "AC joint separation". She reached out to me and asked the above questions. I spent time chatting online and I realized she had not clue what was going on and what to do about it. I decided to share some information here in case you need some help.

What is AC joint?


 The acromioclavicular joint, or AC joint is a joint connecting the acromion and the clavicle as showed in the following picture. 

What is AC joint's function?

Along with other ligaments, It stabilizes the shoulder girdle and maintain appropriate muscle tone of the neck, shoulder and para-scapular muscles. 


What happened during the injury?

When you fell, you landed on the shoulder and directly hit the acromion of the scapula and increased the shear force to separate the AC joint. Sometimes the violence might be strong enough to separate the coracoclavicular ligament, which is also very important. The surgeons would like to assess this ligament's integrity before offering surgery or not.

 There are 6 classes of AC joint separation.
Why do you need to know about this?
Grade 4-6 requires surgery.

 Grade 1-3 can be treated conservatively without surgery as showed on pictures on the right.

 The ligaments might still have a chance to reattach together and get back to full function.

 Tip: Ask your doctor about the severity of the injury and classification of the separation. You might need to come back for a second look in 1-2 weeks with or without update of the X ray.

 As indicated on the picture of Grade 3 AC joint separation, the coracocalvicular ligament might also be separated and the weight of the scapula and upper limb might be pulled down by gravity without support of the ligaments. You neck and upper back and the shoulder muscles might get into spasm and pain due to the pulling of the weight.  Your shoulder might be placed in a sling to decrease that pulling and discomfort.

 There is another treatment option to decrease the discomfort of the shoulder.
Check out the Strapping and taping the AC joint of the shoulder. As a doctor of physical therapist, I do see the benefits of taping for my clients with this diagnosis. I highly recommend the Strapping and taping the AC joint approach.
Pros of taping:
1.direct support between the clavicle and upper arm, decrease the loading of the AC joint.
2.Taping increases the proprioception input of the skin and decreases the compensatory motions of the shoulder girdle.
3. No need to place the arm in internal rotated position and elbow flexion position in a sling for days. So better sleeping!

Cons of taping:
1. Potential skin irritation after prolonged use; Swelling and injury might make it hard to tolerate.
2. Patient might feel overconfident with the taping pain and overdo for a lot motions and ended up with more swelling

Dry Needling by a Physical Therapist: What You Should Know

Dry Needling by a Physical Therapist: What You Should Know I got questions about DN a lot recently. So here is a useful link to learn about Dry needling. https://www.moveforwardpt.com/Resources/Detail/dry-needling-by-physical-therapist-what-you-should A licensed PT with DN training will help you to deal with tightness, pain, and headache. My personal feeling about Dry Needling was not as great at the very beginning, mainly because of the limited evidence we have now.  But after seeing the change of my clients after DN, I recommend DN to all providers and clients. The baseline is the anatomy. Now I see the DN technique as a new approach to get to the deep and sensitive muscles. Usually, I will have to do a lot stretching and adjustment of the spine before the "angry tissues" will relax. That means more pain during the process and less compliant with my client. Now with DN approach, I can pinpoint the compensated tissues quickly. I mean genuinely PINPOINT

A true case of neck herniation presentation

"Surgery, or not surgery?" Recently one of my clients had to make the biggest decision of her life. She will have to make up her mind and accept a fusion surgery on the cervical spine. The risk of paralysis with or without surgery is the biggest concern for her, not to mention the risk of infection, active bleeding and possibly expensive medical bills. Her MRI did show spinal stenosis with 4 intervertebral disks herniations, which match the constant spasm and very limited range of the neck and shoulders. She started to notice the weakness of the legs with mild tripping imbalance accidents. She almost cried when we talked about the possible surgery before further rehab. Constant spasm with tingling of the limbs usually indicates some impinging problem of the peripheral nerves close to the spine.  I strongly suggest anyone with a similar presentation go for professional help immediately. Compared to the expensive medical bills for surgery, the cost to see your PCP or an

What are Shoulder Rotator cuff muscles? Why they might be the source of your upper back, neck and shoulder pain?

WWW.PTcares.com One of my clients was diagnosed with Rotator cuff muscles injury.  She asked me about the rotator cuff muscles and why they are contributing to the shoulder pain and neck pain.  Today we will talk about the function of rotator cuff muscles. There are 4 rotator cuff  muscles: Supraspinatus Infraspinatus Teres Minor Subscapularis The primary function of the rotator cuff muscles is to maintain the stability of the glenohumeral (GH) joint, which is part of the shoulder complex.  As you can see, there are 3 bones in the shoulder complex: Scapula, clavicle and humeral bone. When the rotator cuff muscles are weak and could not maintain the humeral head close to the glenoid of the scapula, the humeral head might not glide smoothly and impinge surrounding tissues, causing connective tissue problems, such as tendinitis, bursitis, capsulitis, or rupture of tendons or ligaments. When the connective tissues and muscles around the sho
