Scoliosis

Definition

Scoliosis is the abnormal sideway curving of the spine (backbone) that begins in infancy, childhood or adolescence.

The spine is made up of the interchange of bones (vertebrae) and discs stacked upon one another running straight down your back.

It is natural for the spine to curve a bit but for people with scoliosis, there is too much curvature of the spine (more than 10 degrees). In these instances, the spine may look like an ‘C’ or ‘S’.

Severe Scoliosis of the Thoracic Spine.

The progression of scoliosis is affected by growth during the first two decades of life.

Early detection, management, and treatment of scoliosis are essential in preventing long-term consequences of the condition.

Symptoms

These are some of the signs and symptoms of scoliosis:

  • Uneven shoulders – one shoulder may be higher than the other.
  • Uneven waist – one hip may be higher than the other.
  • One shoulder blade may appear more prominent that the other.
  • Rolling gait.

As the scoliosis gets worse,

  • Your child or the young person may start experiencing back pain.
  • If the spine starts to rotate as well, the ribs on one side of the chest may become more prominent than the other side.
  • Difficulty breathing is a common complication of scoliosis.
  • Activities that require chest and belly use often tire the person out.

Causes

There are two types of scoliosis:

  1. Nonstructural scoliosis

This occurs when no other abnormalities apart for the sideway curve of the spine is seen. The spine itself is structurally normal with no rotation or asymmetry.

The causes of nonstructural scoliosis include:

  • Postural cause – where the scoliosis is only apparent when the child is standing and disappears on lying.
  • Compensatory mechanism – where the problem is in the legs. When one leg is shorter than the other, the spine naturally curves down to compensate.
  • To avoid pain – one example is irritation of the sciatic nerves leading to altered posture to alleviate the pain.
  • Infection causing pain in the stomach such as in appendicities.

2. Structural scoliosis

This is the type of scoliosis where the spine not only curves sideway but the bones also rotate on top of one another causing asymmetry of the truck.

The causes of structural scoliosis include:

  • Idiopathic – where no associating causes are found. 75-80% of children with scoliosis are idiopathic in nature.
  • Neuromuscular diseases – such as cerebral palsy, poliomyelitis, or muscular dystrophy
  • Birth defects
  • Injury
  • Infections
  • Tumours such as neurofibromatosis
  • Metabolic factors
  • Connective tissue disorders
  • Rheumatic diseases

Risk Factors

These are the risk factors for idiopathic scoliosis, which is the most common type of scoliosis.

  • Age – scoliosis typically starts between the ages of 9-15 when the body is growing. 
  • Gender – girls are at a higher risk of worsening scoliosis and needing treatment for it. However, there is no difference between gender in terms of who gets the disease. 
  • Family history – scoliosis has been shown to run in families at times. However, majority of children with scoliosis don’t have a family history of the disease.

Investigations

The main investigation your doctor will request to diagnose scoliosis is a spine X-ray.

Other tests will vary depending on your condition. These may include:

  • Lung function test – if the scoliosis has affected your breathing.
  • MRI – if there are concerns regarding other symptoms you experience including dizziness and unbalanced walking.

Complications

Treatment

Treatment will depend on the cause of your scoliosis. For most people in idiopathic scoliosis, watchful waiting or the use of a brace is the mainstay of treatment.

  • Observation
  • Brace Treatment
  • Surgery

F.A.Q. | Frequently Asked Questions

What Causes Adolescent Idiopathic Scoliosis?

First, there are many myths about causation (aetiology).

  • It is not a postural problem.
  • You do not get scoliosis from a soft mattress.
  • The carrying of heavy school bags neither causes a curve nor makes an existing one worse.
  • You do not get scoliosis from watching too much television and eating too much junk food.
  • Scoliosis is not contagious – you cannot catch it from someone who has a curvature.
