Clinical Musings (Adolescents) II

We will continue with our discussion of adolescent conditions and injuries that we often see in the clinic.

A year ago a young boy and his father came to the clinic. The boy was 11 years old and was a basketball player. He stated that he plays basketball everyday before and after school. He stated that he was starting to feeling pain in his knees. He stated that this pain is worsening and that running and jumping are extremely painful. His father stated that he holding his son from basketball at this time.

Upon inspection it was seen that the child's knee was indeed swollen at the tibial tuberosity, which can be seen below. This is the structure that anchors your knee cap and the entire quadriceps muscles to the rest lower leg. There is a growth plate at this point and is commonly irritated in growing children. It was also seen that the boy's tibial tuberosity was extremely tender to the touch. He also presented with significant tightening of the quadriceps muscles with testing. What this child was experiencing was Osgood-Schlatter's disease (OS).

Much like Sever's Disease (Discussed last week), Osgood-Schlatter's disease is a terrible name for a somewhat common condition. Much like Sever's Disease, OS is not a disease at all,  but an apophysitis (please see my last post for more information about apophysitis). Instead of a apophysitis of the heel, OS is an apophysitis of the patella tendon. This condition is also caused by rapid bone growth that muscles and tendons cannot keep up with leading to pulling on the growth plate of the tibial tuberosity. 

If left untreated this condition can lead to progressive bone growth at the tibial tuberosity and eventual deformation of the structure. As seen below, the bone growth will become permanent and could cause life long irritation.

The treatment for this condition holding the patient from all jumping and running activities. In the beginning ice is very important to decrease inflammation because NSAIDS (Advil other OTC anti-inflammatories) are not always safe for adolescents. Progressive stretching of the quadriceps and manual mobilizations should also be done by a therapist. 

This patient was non-compliant with treatment and continued with basketball. He is now 15 and has a permanent deformation at the tibial tuberosity that is painful with most active movements. 

Clinical Musing (Adolescents)

Adolescent kids are sometimes the hardest people to treat. They are usually pretty nervous about being treated and they are terrible symptom reporters. Although it is difficult, they are usually the most fun to interact with once they get comfortable with you.

The next few post I am going to outline some common adolescent conditions that we see in the clinic. 

Sever's Disease

A young girl came into the clinic, with her mother, complaining of heel and ankle pain. She is a soccer player and is very active. She stated that she has felt progressive increase in pain with running walking. She stated that at this point she is unable to run and that she is unable to walk without limping. She said the whole ankle and heel is painful. What this patient was experiencing was Sever's Disease.

Sever's Disease (also Sever's Apophysitis/Calcaneal Apophysitis) is actually a terrible name for a somewhat common dysfunction. From here on out I will refer to it as Sever's Apophysitis (SA) because it is actually a more accurate description of the condition. SA is not a disease but is rather repetitive structural damage at the growth plate of the heel from the Achilles tendon. This usually happens in growing children that participate in sports. Apophysitis is technical description of a tendon pulling on a bone to the point that the bone starts to pull away from the rest of the bone. As you can imagine this can be a severely (pun totally intended) painful condition. 

http://en.wikipedia.org/wiki/File:Gray1241.png

As seen above the Achilles tendon attaches to the heel bone at the posterior foot. In pubescent children, bones tend to grow faster than muscles and this causes increased tension along tendons such as the Achilles  There is a growth plate in the heel bone which can become irritated with this increased tension from the Achilles. This increasing irritation is referred to as Sever's Apophysitis. 

Treatment for this condition is usually manual massage of the calf, gentle and progressive stretching and strengthening activities, possibly bracing and taping techniques. Acutely ice and heat are also helpful. It is also important to hold kids from sports activities in the short run to avoid further injury.

This patient is doing much better and has been able to return to practice recently on a limited program. 

Clinical Musings II

A few weeks ago a patient came into the office complaining of shoulder pain with most shoulder movements that woke her up in the night. When asked where the pain was located she stated that the pain was in the lateral shoulder. She then started to rub the outside of her arm. When asked if she feels pain when she rubs her arm in the area that usually hurts with shoulder movement, she stated the she does not.  This is an extremely common presentation for shoulder pain.

What this patient was experiencing was referral pain from the rotator cuff. Lateral shoulder pain that occurs with movement but does not hurt with palpation is usually referral pain from the infraspinatus tendon of the rotator cuff.

The rotator cuff (RTC) is a term that is thrown out there a lot and is usually referred to without much knowledge of what it actually is. The RTC is actually a group of 4 muscles: The infraspinatus, subscapularis, supraspinatus and the teres minor. 

http://www.creativerehab.net/

These four muscles are the primary movers and stabilizers of the shoulder. People think that you only injure your RTC by playing sports, but most often times we can injure these structures by poor posture and repetitive habits. 

The patient I was seeing was an avid exerciser that just finished knee surgery. During that time she was exercising her upper body exclusively and thus caused irritation to her RTC. This is what was causing her pain. More specifically, she was presenting with infraspinatus tendinitis (inflammation of the tendon). 

Treatment for this condition is usually trigger point release techniques (either dry needling or deep massage), Ultrasound, RTC strengthening, and shoulder mobilizations. This patient has been seen for 3 weeks and is showing vast improvements. Unfortunately, physical therapy is not always helpful and more aggressive treatment maybe necessary. 

Clinical Musings

Recently I saw a young patient that plays in several sports that require ballistic shoulder movements. She stated that while pitching in fast pitch softball she felt severe pain in her shoulder and that the pain has not improved in the past few weeks. She stated that the shoulder was tender to the touch and with movement above shoulder height.

Many orthopedist and therapist would suspect only ONE thing… rotator cuff injury. Although this is a perfectly logical assumption one must always be thorough in their examination.

Upon inspection, one thing was immediately noticeable. There was a significant difference in shoulder height (painful shoulder was lower). With this it was important to see if the scapulas are winging. Upon inspection it was seen that her affected shoulder was in fact “winging”.

There are varying degrees of winging and illustrated below is an example of a severely winging scapula. A winging scapula could be more subtle and less noticeable.

These signs should raise a little red flag in a good diagnostician for a possible long thoracic nerve injury.

The long thoracic nerve innervated that serratus anterior (SA). The SA is a muscle that looks much like the serrated end of a knife thus its name the serratus anterior.

The SA is only of the primary stabilizer for the shoulder complex in conjunction with the RTC therefore a long thoracic nerve palsy could be misdiagnosed as a  rotator cuff injury. The primary way of differentiating the two is to look for the winging scapula. 

Working on stabilization of the shoulder and using functional electric stimulation to cause activation of the SA has been very effective in treating this patient. In just two weeks she has improved 70% and is now able to raise her shoulder above her head with no pain. 

Ouch My Knee Hurts!!! [Part 6] Posterior Knee Pain

Posterior knee pain is very common and can be very limiting to ones daily life. Posterior knee pain could mean many things but it is important to narrow down the most likely causes. One of the most common causes of posterior knee pain are the hamstrings. 

The hamstrings are one of the biggest and most important muscles in the legs. Due to its anatomical structure the hamstrings are somewhat vulnerable to injury. The hamstring is the main muscle responsible for bending the knee. The hamstrings come from the hip and attaches to the posterior knee, making the hamstring one of the longest muscles in the body. Not only are the hamstrings very long but they are also very thin. This structure makes the hamstrings vulnerable to injury in a way that we do not see in larger more bulky muscles.  A hamstring strain to this insertion of the hamstrings (Zone 1) could cause pretty significant posterior knee pain.

The posterior knee also contains the origin of the calf (Zone 4), the gastrocnemius.  The calf is the muscle that is used to push the foot down and is integral to jumping. The calf is a very powerful muscle that is strained less often at the origin.

The popliteus is a small muscle in the posterior knee (Zone 2) which helps to “unlock” the knee during walking and running activities. This muscle can become irritated and cause some pain with knee bending and straightening. 

All of these issues are soft tissue issues that will improve with therapy and rest. Ice is also very helpful in reducing pain and irritation in the short run.  Hamstring strains could be more problematic depending on the severity of the injury. See a physical therapist for more information about your knee pain. 

Ouch My Knee!! [Part 5] From Joe Shmo to Joe DiMaggio

Knee pain in Zone 4a and 4b could mean a few things but the main thing we want to rule out is a meniscus tear. If you watch ESPN or listen to sports radio I am sure you have heard of a professional athlete be sidelined for months because of this issue. I also want to make it clear that you do not have to be a professional athlete to suffer from a meniscus tear; this can affect everyone from Joe Shmo to Joe DiMaggio.

 

What is the Meniscus?

The meniscus is the cartilage in the knee that acts as a cushion and a guide for the knee while it bends and straightens. The meniscus is integral for the structure and function of the knee. If you think of the meniscus as both the shocks and the struts of your car, you could imagine how important they are. The meniscus is made up of two C shaped pieces of cartilage that face each other. This creates a deeper surface for the femur (which is the thigh bone) to connect to the tibia (shin bone).

The front and back of the meniscus are delineated into two different sections; therefore there are actually 4 parts of the meniscus that can be damaged. There is the anterior medial meniscus (AMm), posterior medial meniscus (PMm), anterior lateral meniscus (ALm) and the posterior lateral meniscus (PLm). Each one of these parts of the meniscus can be torn or injured. Please note that all drawings of anatomy are incredibly crude and were done by yours truly. Please look up images online if you are confused by my drawings.

What does a meniscus tear feel like?

• Pain with jumping, running and sometimes walking
• Possible clicking or popping in the knee when putting weight on the knee
• Pain feels like stiffness that you can’t shake off
• Feels like the knee is stuck and won’t unlock
• Knee sometimes buckles
• Pain when bending the knee

What causes a meniscus tear?

A meniscus tear is usually caused by more traumatic means such as slipping or getting your foot stuck while performing a cutting maneuver, performing deep heavy squats with improper form, planting the foot while turning the hips at high speeds. More mundane activities could also result in meniscus tears such as, slipping and falling, stepping down a stair incorrectly.

What is another condition that can be confused for a meniscus tear?

• Patella femoral syndrome (See past posts)
• Patella tendinitis (See past posts)
• ACL,MCL,LCL tear (See future posts)

What are some treatments?

Treatment options depend mostly on injury severity. Minor and moderate tears are usually treated with Physical therapy and conservative care. More severe tears could possibly require surgery if physical therapy is ineffective. Please consult with a professional before running to get an MRI or into surgery. Many times physical therapy can help to restore full function without the need for surgery.  

Ouch My Knee!! [Part 4]

Pain in Zone 3 could possibly be caused by quadriceps tendinitis. Quadriceps tendinitis is not as common as some other conditions, however, this condition could cause some serious pain while running and jumping.

The quadriceps are a very large muscle group which are made up of four different heads (illustrated below). 

 The quadriceps are primarily used to extend the knee into a straight position, but are used in basically all standing or dynamic movements (like jumping, sprinting, running, walking). The quadriceps are literally the most important muscles in the leg. This huge muscle group that is so important to all movement of the knee attaches to a very small bone called the patella. 

We have talked about the patella at length in other blogs so I encourage you to read parts 1-3 of this series. One interesting part of the patella tendon is that it is what is called a “floating bone” meaning that the patella or “knee cap” has no ligamentous connection to any other bone. Most bones are connected to other bones through ligaments but the patella actually just "floats" on top of the knee connected to the body only though tendons [Just as a side, tendons connect bone to muscle, whereas, ligaments  generally connect bone to bone].

Because the patella does not have any ligamentous connection it is a very unstable bone that is affected by outside forces such as the quadriceps. The attachment of the quadriceps on the patella is called the patella tendon (muscle to bone).  

What does quad tendinitis feel like?

• Pain right above the patella with running, jumping, squatting
• Swelling in the area above patella
• Pain when rubbing quad tendon

What causes quad tendinitis?

• Lack of stretching of the quadriceps
• Lack of warming up of said muscle group
• Inappropriate progression of exercise program

What is another condition that could be confused with quad tendinitis?

 A quad strain could be confused with quadriceps tendinitis. A quadriceps strain will cause pain in the thigh could be located anywhere along the quadriceps muscles.

What are some treatments?

Resting and ice are a good first step, but all painful activities should be stopped. Stretching and modification to exercise should be considered when returning to exercise routine. Of course physical therapy is a good option if pain does not improve in 3 weeks.
