A child slouching at the dining table or leaning slightly to one side is often dismissed as poor posture or the result of carrying a heavy school bag. However, medical experts are urging parents to pay closer attention, as these subtle signs could indicate scoliosis, a spinal condition that often develops silently during childhood. According to Dr Saw Lim Beng, Consultant Robotic and Spine Surgeon at Sunway Medical Centre, Sunway City (SMC), scoliosis is far more than a posture problem. It is a three-dimensional spinal deformity in which the spine curves and rotates, affecting the body's overall alignment and balance.

One of the biggest challenges with scoliosis is that it usually develops without pain or obvious symptoms in its early stages. Dr Saw explains that many cases appear mild initially and may only become noticeable during a child's rapid growth period between the ages of 10 and 15. During this stage, the spine can grow quickly, allowing a small spinal curve to progress significantly within a relatively short period. As a result, regular medical follow-ups are essential for children diagnosed with scoliosis to ensure timely intervention if the condition worsens.

While scoliosis may not cause discomfort in its early stages, its physical effects become more apparent as the curvature progresses. Parents may notice uneven shoulders or hips, one side of the body appearing higher than the other, muscle fatigue caused by imbalance, or a visible curvature of the spine. Beyond the physical symptoms, the emotional impact can be equally significant. Many children and teenagers become self-conscious about their appearance, avoiding social situations or attempting to conceal the changes with loose clothing or hairstyles. Such experiences can affect self-esteem, confidence and overall emotional well-being, particularly during adolescence.


Dr Saw also highlighted a common misconception that poor posture or carrying heavy school bags causes scoliosis. In reality, 80 to 90 per cent of scoliosis cases are classified as idiopathic, meaning the exact cause remains unknown. Although poor posture and heavy backpacks may contribute to temporary back discomfort, they do not cause the spine to curve. Misunderstanding this often delays proper diagnosis and treatment, preventing children from receiving appropriate care at an early stage.

The good news is that early detection can often reduce the need for surgery. Many mild to moderate cases can be managed through non-surgical treatments such as customised braces, specialised physiotherapy exercises and regular monitoring during periods of growth. Advances in customised 3D braces and targeted rehabilitation programmes have improved treatment outcomes by helping to control curve progression and support better spinal alignment.


For more severe cases, surgery may become necessary, particularly when the spinal curve exceeds 45 degrees or continues to progress despite conservative treatment. Dr Saw noted that modern spinal surgery has advanced considerably through improved imaging technology, surgical planning and robotic-assisted techniques. At Sunway Medical Centre, robotic-assisted systems are used in selected cases to support surgical precision and decision-making, although surgery remains the final option after non-surgical treatments have been exhausted.

One of the greatest risks is delaying medical assessment in the hope that the condition will resolve naturally. By the time specialist care is sought, the spinal curve may have progressed to a stage requiring more complex treatment and a longer recovery period. Dr Saw emphasises that parents should be alert to warning signs such as uneven shoulders, clothing hanging unevenly, a prominent rib hump when the child bends forward, a body that consistently leans to one side or an uneven pelvis while walking. Simple observations such as the Adam's Forward Bend Test may help identify potential concerns, but any suspicion should be followed by professional medical evaluation.

In conjunction with Scoliosis Awareness Month, healthcare professionals are encouraging parents to look beyond posture and recognise scoliosis as a medical condition that benefits greatly from early diagnosis and intervention. With timely treatment and appropriate monitoring, many children with scoliosis can continue to lead active, healthy lives while avoiding more invasive procedures later in life.
