Key Takeaways
- Poor posture does not typically cause structural scoliosis, although it can make an existing spinal curve more noticeable.
- The causes of scoliosis vary and may include genetic, congenital, neuromuscular and age-related factors.
- Scoliosis involves a sideways curvature of the spine, often accompanied by some rotation of the vertebrae.
- Early assessment can help determine the type and severity of spinal curvature and guide appropriate management.
Can Poor Posture Cause Scoliosis?
Slouching at a desk, leaning towards one side or spending long hours looking down at a mobile phone can contribute to poor posture. Over time, these habits may cause muscle discomfort, stiffness and postural imbalances. However, they are not considered direct causes of structural scoliosis.
Scoliosis is a condition characterised by an abnormal sideways curvature of the spine, typically involving a rotation of the vertebrae as well. Unlike ordinary postural changes, this curvature does not simply disappear when a person straightens their back.
While poor posture may make the shoulders or hips appear uneven, structural scoliosis involves changes in the alignment of the spine itself.
What Are the Common Causes of Scoliosis?
The causes of scoliosis depend on the type of condition. In many cases, particularly among adolescents, the exact cause remains unknown.
Here are some recognised types and contributing factors,
- Idiopathic Scoliosis
Idiopathic scoliosis is the most common type, particularly among children and adolescents. The term ‘idiopathic’ means that the exact cause is unknown.
It often becomes noticeable during periods of rapid growth, such as puberty. Although the precise cause has not been established, genetic factors may contribute to its development.
- Congenital Scoliosis
Congenital scoliosis develops before birth due to abnormalities in the formation or segmentation of the vertebrae.
These structural differences may cause the spine to curve as a child grows. The severity and progression can vary depending on the underlying spinal abnormality.
- Neuromuscular Scoliosis
Neuromuscular scoliosis can develop in individuals with conditions affecting the muscles or nervous system.
Conditions such as cerebral palsy, muscular dystrophy and spinal muscular atrophy may affect the muscles responsible for supporting the spine, resulting in an abnormal curvature.
- Degenerative Scoliosis
Also known as adult-onset or degenerative scoliosis, this type develops later in life due to age-related changes in the spine.
Factors such as disc degeneration, arthritis and changes in the spinal joints can affect spinal alignment and contribute to curvature.
There is also a condition known as functional scoliosis, where the spine appears curved due to factors such as leg length differences, muscle spasms or other temporary imbalances. Unlike structural scoliosis, the curve may improve when the underlying cause is addressed or the person’s position changes.
A clinical assessment is necessary to determine whether an observed spinal curve is structural or functional.
What Are the Signs That You May Have Scoliosis?
Scoliosis does not always cause noticeable symptoms, particularly in its early stages. However, some common signs include,
- One shoulder appears higher than the other.
- Uneven hips or waistlines.
- One shoulder blade appeared more prominent.
- A visible difference in the alignment of the back.
- One side of the rib cage appearing more prominent when bending forwards.
- Back discomfort or pain, particularly in some adults with degenerative scoliosis.
In children and adolescents, scoliosis may become noticeable during routine growth checks or when parents observe changes in posture.
If these signs are present, an orthopaedic assessment can help establish whether the asymmetry is related to scoliosis or another underlying condition.
How Is Scoliosis Diagnosed and Managed?
Diagnosing scoliosis typically involves a physical examination and an assessment of spinal alignment.
A doctor may perform a forward bend test to look for asymmetry in the back. If scoliosis is suspected, standing spinal X-rays may be recommended to assess the curvature and measure its severity using the Cobb angle.
Management depends on several factors, including,
- The degree of spinal curvature.
- The patient’s age and remaining growth.
- Whether the curvature is progressing.
- The presence of pain or other symptoms.
- The underlying cause of the condition.
Depending on these factors, management may include,
- Observation- Smaller curves may require periodic monitoring, particularly in growing children.
- Bracing- A spinal brace may be recommended for certain growing adolescents to reduce the risk of curve progression.
- Physiotherapy- Specific exercises may help improve muscle strength, flexibility, posture and physical function.
- Surgery: In selected cases involving significant or progressive curves, surgical treatment may be considered.
Not every person with scoliosis requires active treatment. An individualised assessment helps determine the most appropriate approach.
Frequently Asked Questions
1. Can sitting for long hours cause scoliosis?
Sitting for prolonged periods or maintaining poor posture does not typically cause structural scoliosis. However, these habits may contribute to muscle discomfort and postural imbalances.
2. Is scoliosis hereditary?
Genetic factors may contribute to certain types of scoliosis, particularly adolescent idiopathic scoliosis. However, having a family history does not necessarily mean that a child will develop the condition.
3. Can scoliosis develop in adulthood?
Yes. Adults can develop scoliosis due to age-related degeneration of the spinal discs and joints. Some adults may also have scoliosis that developed during childhood but was not previously diagnosed.
4. Can exercise correct scoliosis?
Exercise and physiotherapy may help improve muscle strength, mobility and physical function. Certain scoliosis-specific exercises may also help with curve management. However, exercise alone does not reliably correct an established structural spinal curvature.
5. Does scoliosis always cause back pain?
No. Many individuals with scoliosis do not experience significant pain, particularly during childhood and adolescence. Some adults may develop back discomfort due to degenerative changes or altered spinal mechanics.
Schedule a Consultation And Get Your Spinal Alignment Assessed
An uneven shoulder line or a change in posture does not automatically indicate scoliosis. However, persistent asymmetry or visible changes in spinal alignment should not be overlooked.
Understanding the underlying causes of scoliosis is an important first step towards appropriate assessment and management. If you have concerns about spinal curvature, posture or persistent back discomfort, consider arranging an orthopaedic consultation.
At MASH Spine & Orthopaedics, Dr. MASH can assess your spinal health, discuss potential causes and advise on suitable management options based on your individual condition.
