Scoliosis (Spinal Curvature): Causes, Symptoms, and Treatment
Request Call Back
Overview
Scoliosis, also known as spinal curvature, is a musculoskeletal condition where the spine curves sideways, often resembling the shape of the letter “S” or “C.” In a healthy spine, when viewed from the back, the vertebral column appears straight. However, in scoliosis, the curvature is noticeable and can vary in severity.
Most cases of scoliosis are mild, but in advanced cases, the spinal deformity may cause complications such as chronic pain, reduced mobility, and breathing difficulties. Early diagnosis and timely treatment are crucial in preventing progression and maintaining a good quality of life.
At MedicalPoint Hospital, our multidisciplinary team of orthopedic surgeons, neurosurgeons, and rehabilitation specialists provide comprehensive scoliosis care—from screening and diagnosis to personalized treatment strategies.
What Is Scoliosis?
Scoliosis is defined as a sideways curvature of the spine that typically occurs during the growth spurt before puberty, although it can also develop in adulthood. The human spine consists of 33 vertebrae and has natural curves that support posture, balance, and movement. In scoliosis, these curves become abnormal, shifting laterally in the coronal plane.
Though commonly described as a two-dimensional condition, scoliosis is actually a three-dimensional deformity, as it involves rotation of the vertebrae along with side curvature.
Causes of Scoliosis
Scoliosis can be classified into non-structural (functional) and structural types.
- Non-structural scoliosis – Often results from external factors such as leg length discrepancy, muscle spasms, or posture-related issues. The spine itself remains structurally normal, and the curvature may resolve once the underlying cause is corrected.
- Structural scoliosis – Represents permanent spinal deformity. In many cases, the cause is idiopathic (unknown), but other factors may include:
Common Causes and Risk Factors:
- Neuromuscular disorders: Conditions such as cerebral palsy or muscular dystrophy.
- Congenital anomalies: Malformations of vertebrae that occur during fetal development.
- Trauma or infections: Injuries, surgeries, or spinal infections affecting bone growth.
- Genetics: Family history may increase susceptibility.
- Age and growth spurts: Curves often progress rapidly during adolescence.
- Gender: While scoliosis affects both genders, progression is more likely in females.
Types of Scoliosis
Scoliosis is categorized based on cause and age of onset:
- Idiopathic scoliosis – Accounts for about 75–80% of cases. It usually appears in adolescence and may be linked to genetic and environmental factors.
- Congenital scoliosis – Caused by abnormal spinal development during pregnancy; often detected in infancy or childhood.
- Neuromuscular scoliosis – Associated with neurological or muscular diseases such as cerebral palsy or spinal muscular atrophy.
- Degenerative scoliosis – Occurs in adults due to spinal degeneration, arthritis, or osteoporosis.
Symptoms of Scoliosis
Mild scoliosis may not produce noticeable symptoms. However, as the curvature progresses, the following signs may appear:
- Uneven shoulders (one higher than the other)
- Prominent shoulder blade or rib hump
- Uneven hips or waistline
- Head not centered over the pelvis
- Back pain or stiffness
- Visible S-shaped or C-shaped curve when bending forward
- Fatigue due to muscle imbalance
- In severe cases: breathing difficulties due to reduced lung capacity
Diagnosis of Scoliosis
At MedicalPoint Hospital, scoliosis is diagnosed through a combination of physical examination and imaging tests.
- Physical exam: Doctors check for uneven shoulders, hips, or rib cage, often asking the patient to bend forward (Adam’s forward bending test).
- X-rays: Provide detailed images of the spine and allow measurement of the curve angle (Cobb angle).
- MRI or CT scans: Used in complex cases to evaluate spinal cord abnormalities or congenital malformations.
A spinal curve of more than 10 degrees on X-ray is typically defined as scoliosis.
Treatment Options for Scoliosis
Treatment depends on the severity of curvature, age, skeletal maturity, and underlying cause.
- Observation and Monitoring
- Mild scoliosis (curves less than 20 degrees) may only require regular monitoring every 6–12 months.
- Children and adolescents undergoing growth spurts need closer follow-up.
- Bracing
- Used for moderate scoliosis (20–40 degrees) in growing children and teens.
- Braces do not cure scoliosis but can prevent further progression.
- Types include underarm braces (TLSO) and Milwaukee braces.
- Physiotherapy and Exercise
- Targeted exercises improve posture, muscle balance, and spinal stability.
- Techniques such as the Schroth method are widely used in rehabilitation.
- Surgery
- Recommended for severe curves (usually greater than 45–50 degrees) or rapidly progressing scoliosis.
- Spinal fusion: Vertebrae are fused together using bone grafts, rods, and screws to prevent worsening of the curve.
- Growing rods: Used in children, allowing the spine to grow while controlling curvature.
- Advances in minimally invasive and robotic-assisted spine surgery at MedicalPoint Hospital provide safer and more precise correction.
Living with Scoliosis
With appropriate treatment, most patients lead normal lives. However, untreated severe scoliosis can lead to:
- Chronic back pain
- Decreased lung and heart function
- Reduced mobility and self-esteem
- Visible deformity affecting quality of life
At MedicalPoint Hospital, scoliosis care includes rehabilitation, physiotherapy, pain management, and psychological support to address both physical and emotional aspects of the condition.
Conclusion
Scoliosis is a common spinal deformity that ranges from mild curves requiring observation to severe cases needing surgical correction. Early detection and personalized treatment are crucial for preventing complications and improving long-term outcomes.
At MedicalPoint Hospital, we combine state-of-the-art imaging, advanced surgical techniques, and personalized rehabilitation programs to deliver world-class scoliosis care. Our goal is to help patients regain function, reduce pain, and improve posture and quality of life.
