Pectus Excavatum and Scoliosis
Scoliosis is a sideways curvature of the spine that usually occurs in the growth spurt, right before puberty hits.
According to MayoClinic, about 3% of all adolescents have scoliosis.
In most people, scoliosis is moderate.
However, certain deformities like pectus excavatum can further worsen the scoliosis seriousness, as the sufferer gets older.
Severe scoliosis can cause a lot of trouble. It can reduce the amount of space in the chest, which will restrict lung functioning.
If the patient also suffers from a severe case of a pectus excavatum deformity, which is proven to reduce lung capacity in some patients, things get a lot messier.
7 Most Common Symptoms
7 Possible Complications
Even though most people think that scoliosis is unharmful, it can cause complications.
As stated by MedLinePlus, these are the seven most common possible complications.
Does Repairing Pectus Excavatum Fix Scoliosis?
This was unknown until a group of researchers published a study about this subject in 2017.
The study revealed how correcting pectus excavatum impacts pre-existing scoliosis.
779 patients with pectus excavatum who underwent Nuss procedure between the period of 2007 and 2011 were examined.
It was discovered that pectus excavatum repair with a Nuss bar could correct scoliosis.
However, when the preoperative Cobb angle is higher than 15°, scoliosis may be worsened.
Surgeons must be careful while they operate a pectus excavatum patient with moderate scoliosis (Cobb angle > 15°).
Correcting pectus excavatum can both worsen and correct scoliosis. That depends on the Cobb's angle.
Nuss Procedure Can Cause Scoliosis
A study in 2003 reported two cases of acquired scoliosis, following a Nuss procedure to repair a severely indented chest.
A 14-year-old was referred to undergo a Nuss procedure to fix the dent in his chest.
Before surgery, a posteroanterior chest X-ray showed no presence of scoliosis.
The kid underwent a successful Nuss procedure.
Four weeks after the surgery, the boy was seen to have a curvature in the back.
At a follow-up, a right-sided thoracic curve with a Cobb angle of 54° was determined.
The surgeons decided to stop the curve progression and remove the Pectus bar.
After bar removal, the Cobb angle reduced from 54° to 41°.
The kid was also given a brace to wear for up to 12 hours a day.
After three months, scoliosis has disappeared.
The researchers confirmed that the Nuss procedure could cause scoliosis by the fact that it was fixed after the Pectus bar removal.
They concluded that the spine must be regularly measured before and after a Pectus excavatum surgery.
If scoliosis occurs after surgery, the researchers suggest physical therapy and bracing to fix it effectively.
The surgeries were performed successfully in all patients.
Postsurgically, scoliosis has developed in two of the patients.
This study proves that a Nuss procedure can cause scoliosis.
In a research, 406 patients suffering from pectus excavatum underwent a Nuss procedure.
The surgeries were performed successfully in all patients.
Postsurgically, scoliosis has developed in two of the patients.
This study further proves that a Nuss procedure can cause scoliosis.
Few scientific articles prove that scoliosis was caused by undergoing a Nuss procedure.
Scoliosis in Women
Scientific research published in 2011 tested 248 patients diagnosed with pectus excavatum.
Researchers concluded that 56 out of all patients had scoliosis, with a Cobb angle higher than 10°.
That's approximately about 22.58%.
They also concluded that scoliosis was more prominent in females.
38.46% out of all female patients had scoliosis, in comparison to males who had 18.37%.
The study concluded that there was a significant correlation between scoliosis and pectus excavatum.
Patients suffering from the deformity have a higher predominance of scoliosis than regular people.
Thirty-seven patients with pectus excavatum were divided into two groups in a study published in 2017.
The study revealed that there was no significant difference between the severity of pectus excavatum, with the severity of scoliosis.
However, scoliosis will worsen as the patient gets older.
That is caused by the heart, which is compressed by the sunken chest. It produces a horizontal push that forces the spine to the right.
There was a notable difference in the two age groups in the severity of scoliosis.
The Cobb angle in the adult group was a lot higher than in the kid's group.
28 out of all 37 patients tested had a Cobb angle > 10°.
20 out of 28 of these patients were adults.
The scoliosis severity is higher in the adult group.
Also, roughly 90% of all patients in the adult group had scoliosis.
On the other hand, scoliosis was present at 53.33% of the patients in the kid's group.
Studies revealed that scoliosis is present twice as much in female pectus excavatum sufferers than male. The spine curvature can also get worse with age.
How Does Pectus Excavatum Cause Scoliosis?
Researchers believe it’s happens when the bones get more calcified, the costal cartilages get fragile and more ossified, with age.
The funnel chest creates an internal horizontal compression that pushes the heart to the left.
The heart creates a counterforce that pushes the thoracic vertebrae to the right, further worsening the curvature.
That is why most patients with sunken chests are bent to the right.
This internal force is believed to make scoliosis worse as the pectus excavatum patient gets older.
What to Do
Once scoliosis is diagnosed, and you already know that you have the pectus excavatum deformity, you should start treatment immediately.
Don't let scoliosis get worse day by day.
The dent in the chest can push the heart to the right. The heart reacts to it with counterforce, and it can push the spine to the right.
Double crush to the thorax
The combination of scoliosis and pectus excavatum lead to more significant cardiopulmonary impairment, than if they occur in separately.
This is called a "double crush to the thorax".
The combination of both thoracic abnormalities aroused the interest of the surgeons in the last few years.
Most Common Type of Scoliosis for Pectus Excaavtum
As stated in a 2017 scientific research, 20, out of 37 patients with pectus excavatum had a spinal curvature to the right.
That is called dextroscoliosis.
Eight out of 37 patients had curvature to the left (levoscoliosis).
The remaining patients had no scoliosis, or their Cobb angle was not higher than 10°.
The study concluded that dextroscoliosis is the most common type of scoliosis in pectus excavatum patients.
Dextroscoliosis is a type of scoliosis when the spine curves to the right.
In pectus excavatum patients, it usually affects the middle-to-upper back, also known as the thoracic spine.
This is confirmed in a 2014 research where they concluded that 85-90% of all adults have dextroscoliosis.
According to Healthline, if the dextroscoliosis is severe, it can press other organs in your body.
It can lead to:
How to Know if You Have it
If you're wondering what type of scoliosis you have, you should ask a doctor for a physical examination.
That's the safest way to proceed in treating this type of scoliosis.
The doctor will take a look at the following things:
According to MedicalNewsToday, there are a few exercises that will improve scoliosis symptoms, non-surgically.
They will also lengthen the spine, expand the chest, strengthen the musculature in your back.
The first stretch to fix Dextroscoliosis is targeting the glutes.
To do this exercise, lay down on the floor, or on a gym mat if you have one.
Bend both knees right in front of you, and place the right foot on your left knee.
Then, lift both legs, and interlace your fingers behind the left knee/hamstring area.
Pull gently toward your chest until you feel a gentle stretch on your glutes.
Then, switch the legs and repeat the stretch for the other leg.
If you have dextroscoliosis, it is usually the right glute that will feel tighter than the other. That was the case for me.
Because of that, I stretched my right leg more than my left, up until my dextroscoliosis was corrected.
Knee to Chest Stretch
This is a fantastic stretch for the hips and the lower back.
To start the exercise, slowly roll yourself down on your back, one vertebra at a time.
Then, bend both knees while laying flat on a surface.
Put your hands behind one knee, and pull it gently toward your chest.
Then, fully straighten the other leg on the surface.
You will feel the stretch in the back of the hip of the leg you're pulling. At the same time, you'll feel it in front of the opposite hip.
For faster results, I recommend you repeat this three times a day.
Kneeling Lunge Stretch
This stretch will help you increase the mobility and control in your hips.
To start, get into a push-up position.
Then, raise your left leg and bring it forward toward your left hand. Put your foot right next to the hand.
Make sure your knee stands directly over your foot. Don't let it go past your toes.
This will put a more significant stretch on the hip, which is the point of this exercise.
Then, bend the knee of the right leg (straightened leg) and slowly put it on the floor.
Bend forward at the hips. Do this slowly. There is no point in rushing.
Breathe into the stretch. As you exhale, bend the hips forward.
Repeat with your right leg.
Stand tall with your feet set at shoulder-width-apart.
Fully extend your left arm and point up to the ceiling.
Stretch the opposing hand down as far as you comfortably can.
Make sure you keep your body sturdy, without leaning to the side.
Hold this stretch for about 30 seconds.
Lower the left arm and repeat with the right arm up.
Reclined Butterfly Stretch
The lying butterfly stretch is an excellent opener for tight hips.
You'll feel the benefits instantly.
Lay down on your back.
Bend at the knees and bring the ankles to touch together.
Put your hands on both knees, and gently press the knees away from each other.
Don't push this stretch.
Allow the hips to stretch more and more with each breath.
Dextroscoliosis is the most common type of scoliosis in pectus excavatum patients. It can be corrected through physical therapy, bracing and surgery.
Levoscoliosis is a type of scoliosis in which the spine curves to the left side.
The curve occurs in the lower back, or in some cases in the middle back.
Generally, the symptoms are the same as in dextroscoliosis.
The only difference is that they will happen on the other side of your body.
Levoscoliosis is less frequent in pectus excavatum patients. It can be fixed through bracing, surgery, chiropractic treatment and exercises.
Make an Appointment to Orthopaedic Doctor
It is in your best interest to visit an orthopaedic doctor to discuss the severity of scoliosis.
The doctor will look at your scoliosis and provide you with a custom physical therapy program.
The spinal curvature is different in everyone.
There isn't a one program solution that fixes all cases of scoliosis.
Show the exercises I've shown above to your doctor.
Some of them would be great for your case, and some wouldn't.
An orthopaedic doctor appointment will be very beneficial in correcting scoliosis associated with the funnel chest condition.
Yoga for Scoliosis
Yoga is a fantastic way to treat scoliosis without surgery.
It focuses on spine realignment, relaxation in the muscles, and stretching of the muscles and ligaments.
Yoga both strengthens and lengthens.
In a study, patients with scoliosis who practised the side plank pose saw an improvement in the Cobb angle of 45% on average.
Strengthening the convex side of the curve with this practice, significantly reduces the scoliosis curvature.
As written by MedicalNewsToday, yoga is fantastic for people with scoliosis.
Poses like the Cat, the Tree, and the Mountain are incredibly helpful.
The breathing work in Yoga will also improve the lung capacity in pectus excavatum patients.
After each yoga session, you will feel more energized.
In some cases, yoga is a very effective way to treat both types of scoliosis associated with pectus excavatum.
The pectus excavatum deformity can worsen the severity of scoliosis.
If left untreated, scoliosis can worsen and cause problems to your wellbeing.
The heart of a patient with a funnel chest is compressed and pushed to the side.
That creates pressure on the spine, which, with time, curves even more, further worsening scoliosis.
There is scientific evidence that undergoing a Nuss procedure can improve scoliosis.
However, if the curvature is severe, the surgery can further aggravate it.
Also, there is evidence that the Nuss procedure can also cause scoliosis.
If you suffer from pectus excavatum, you will probably have dextroscoliosis (spine that curves to the right).
On the other hand, it is less common to suffer from levoscoliosis.
There are a few treatment options.
The most effective non-surgical treatments are bracing and performing corrective exercises.
However, I still highly recommend you visit an orthopaedic doctor to examine the curvature.
The doctor will tell you what you exactly need for your case.
