Congenital Scoliosis: Causes, Treatment, and Symptoms

congenital scoliosis

There are many different types of scoliosis a person can develop. The condition can affect any age and develops irrespective of gender, race, and socioeconomic factors. A condition’s cause, when known, helps classify the condition. Congenital scoliosis is one of the less typical condition forms with a known cause.

Congenital scoliosis is the presence of an abnormal spinal curvature that affects newborns and/or young infants. Sometimes referred to as ‘infantile scoliosis’, when scoliosis is congenital, the abnormal spinal curvature develops in utero. The curvature makes the spine bend to the left or right, in the shape of an ‘S’ or a ‘C’.

While scoliosis is most commonly diagnosed in adolescents between the ages of 10 and 18, younger children and infants can develop the condition too. Infants with congenital scoliosis often have other medical issues such as bladder or kidney problems.

Scoliosis and Babies

When scoliosis is diagnosed in children under the age of 10, this is often referred to as ‘early-onset scoliosis’. Within that group, the youngest cases involving children under the age of 3 are further categorized as ‘infantile scoliosis’.

In cases of infantile scoliosis with small curvatures, it’s possible that the abnormal spinal curvature will self-correct without treatment. While some cases of infantile scoliosis resolve themselves by the age of 3, others can progress with maturity, and of course, there is no definitive means of predicting which cases will get worse, and which will improve on their own.

It is very important to understand that even though some cases of infantile scoliosis resolve without treatment, in those that do not, they are facing a higher chance of progressing to severe levels and causing issues later in life.

in most cases of infantile 400Infantile scoliosis is often related to other disorders. In most cases of infantile scoliosis when the patient is under the age of 3 with a Cobb angle measurement of 20+ degrees, MRI’s are commonly recommended.

Congenital Scoliosis in Babies

Scoliosis in patients under the age of 3 is often congenital, meaning its development is due to a bone malformation in the spine that occurred before birth. Congenital scoliosis occurs in approximately 1 in 10,000 newborns and is far less common than adolescent idiopathic scoliosis that accounts for 80 percent of known diagnosed cases.

The spine is made up of individual bones called vertebrae. These bones are stacked on top of one another, separated by intervertebral discs. If you picture the bones of the spine as rectangular in shape, imagine one of those bones is, instead, triangular in shape.

Imagine how one misshapen vertebra could throw off the alignment of the entire spine. In cases of congenital scoliosis where one part of the body did not develop and form properly, it’s not uncommon for there to be other areas or body parts that are also malformed; this is why, in cases of congenital scoliosis, a thorough assessment of all body systems is necessary.

Types of Congenital Scoliosis

The spine is a complex and important part of human anatomy with three main natural and healthy curvatures characterizing the spine’s three main sections: cervical (neck), thoracic (middle and upper back), and lumbar (lower back).

The spine can develop a number of conditions, and even within a single condition, such as congenital scoliosis, there can be important differences that contribute to the condition’s development.

Incomplete Vertebrae Formation

The spine develops and forms before birth, and if one or more vertebrae don’t form completely, this abnormality is known as a ‘hemivertebra’. When this happens, the spine tends to produce sharp angles, and that angle can get worse as a child develops and grows.

This abnormality can involve one vertebra or many. When there are multiple hemivertebrae, they can counteract each other, balancing each other out and making the spine more stable.

When the Vertebrae Fail to Separate

As a fetus develops in utero, the spine initially forms as a single column of tissue; later, this column separates into individual segments, becoming vertebrae (bones of the spine). When this separation isn’t complete, a partial fusion can occur, joining two or more vertebrae together as one solid bone (bony bar).

Bony bars of this nature prevent the spine from growing evenly on both sides after the child is born.

Bars and Hemivertebrae Combination

When there is a combination of a hemivertebra on one side of the spine and a bar on the other, this can cause serious growth problems. These types of cases are severe as there are two issues impacting the spine’s health.

Surgery is often recommended at an early age to prevent the spine’s abnormal curvature from increasing.

Compensatory Curves

A child’s spine can develop what’s known as ‘compensatory curves’, in addition to scoliosis curves.

Compensatory curves develop in an effort to maintain a straight and upright posture. This occurs when the body responds to the presence of unnatural scoliosis curves by putting in spinal curves in the opposite direction, either above or below the affected area.

Congenital Scoliosis Symptoms

Most often, congenital scoliosis is diagnosed after a pediatrician notices an abnormality to the back during a routine examination.

As scoliosis in children is not painful, if the condition is not noticed at birth, it can remain undetected until it starts to produce noticeable signs and symptoms. In fact, it’s not uncommon for these conditions to remain undetected until adolescence.

Teenagers noticing that their clothing isn’t fitting properly, or parents noticing something seems wrong when they see their adolescent in a bathing suit is often how these late discoveries are made.

Other physical signs of scoliosis include:

  • Tilted and/or uneven shoulders
  • One shoulder blade protruding more than the other
  • One side of the rib cage protruding more prominently
  • An uneven waistline
  • One hip sitting higher than the other
  • An overall tilting appearance to the body
  • Rarely, issues with the spinal cord and/or nerves can produce weakness, numbness, and/or a loss of coordination

Congenital Scoliosis Treatment

When planning a child’s congenital scoliosis treatment plan, their doctor will factor in the type of spinal abnormality, the severity of the curvature, and any other relevant health issues present.

The doctor will gauge how likely it is that the child’s curvature will progress and suggest different treatment options that best address the child’s specific condition and needs.

as is the case with other 400As is the case with other forms of scoliosis, there are two main treatment choices: surgical and nonsurgical.

Surgical Treatment for Congenital Scoliosis

While every case is different, in most cases, surgical treatment is recommended for patients who have curvatures that are clearly progressing, are particularly severe, have large spinal and/or trunk abnormalities, or are developing a neurological issue due to the spinal cord’s abnormality.

When surgery is the chosen course of treatment, the goal is to let the spine and chest grow as much as possible, and there are multiple different types of spinal surgery:

Spinal fusion: the most-tilted vertebrae are fused together into one solid bone. This will eliminate movement in the affected area, meaning that progression will likely be stopped.

Hemivertebra removal: the removal of a single hemivertebra. This partial correction of the curvature is then further managed with metal implants. The procedure fuses two or three vertebrae together.

Growing rods: growing rods can be lengthened to accommodate a growing spine while working towards correcting a curvature. These rods can be lengthened with minor surgery that’s repeated every six to eight months.

One or two of these rods are attached to the spine above and below the site of the curvature.

Every six to eight months, the rod is lengthened, and when the child is full grown, the rods are replaced, and spinal fusion is performed.

Nonsurgical Treatment for Congenital Scoliosis

Here at the Scoliosis Reduction Center, our treatment goals for our congenital scoliosis patients are similar to our other patients: reduce the curvature size, prevent further progression, improve function, provide long-term stabilization, and if a patient is going to have surgery, prepare them, and their families, for as positive a surgical outcome as possible.

As there is no reliable method for determining whether an infant’s scoliosis is going to progress or remedy itself, or what their curvature size will be in the future, treatment can be a delicate balance of observation and action.

Once a curvature progresses past 25 degrees, that curvature tends to continue progressing into maturity, if left untreated. When a curvature is small is almost always the best time to act as we can take those proactive steps towards stopping that small curvature from becoming larger.

As growth is the number-one trigger for progression and infants have a lot of growth ahead of them, scoliosis curves can increase as the spine grows.

X-rays are a large component of observing how the spine is responding to treatment. When we are treating infants with scoliosis, there are certainly some unique challenges.

Our treatment plans for infants are customized and specific to each patient. These plans often include modified scoliosis-specific therapy and/or corrective bracing so that any age-specific challenges are addressed.


Congenital scoliosis is an abnormal sideways curvature of the spine that develops due to a spinal abnormality that occurred in utero.

It’s not uncommon for children with congenital scoliosis to have other health issues, which is why a comprehensive assessment of the body’s systems and parts are necessary.

Although congenital scoliosis develops in utero and is present at birth, it’s not uncommon that the condition remains unnoticed until adolescence, when the growth spurts associated with puberty cause further progression and noticeable symptoms.
