The vertebral column is composed of 24 vertebrae forming three curvatures in the sagittal plane: cervical lordosis (7 cervical vertebrae), thoracic kyphosis (12 thoracic vertebrae), and lumbar lordosis (5 lumbar vertebrae). Additionally, it includes the sacral kyphosis and coccyx, which consist of 5 fused sacral vertebrae and 4 fused coccygeal vertebrae.
Scoliosis is the most common spinal deformity in children, affecting 2 to 3% of the pediatric population. It is characterized by a three-dimensional deformity of the spine, including vertebral rotation and a lateral curvature that often appears in an 'S' shape.
The Cobb angle is used to quantify the degree of spinal deformity in scoliosis. It is measured on radiographs by identifying the most tilted vertebrae at the top and bottom of the curve and helps in monitoring the progression of the condition.
During a clinical examination for scoliosis, signs such as vertebral rotation and gibbosity are assessed. The presence of gibbosity, which is a prominent rib hump on one side of the back, is a pathognomonic sign of scoliosis.
Radiological examination, particularly X-rays, is crucial in diagnosing scoliosis as it helps eliminate secondary scoliosis and assess the three-dimensional deformity of the spine. It is performed in both frontal and sagittal planes.
The prognosis of scoliosis is significantly influenced by growth spurts during puberty, particularly between the ages of 10 and 16. The risk of worsening deformities increases during this period due to rapid bone growth.
Treatment for scoliosis may include functional therapy focused on de-lordosis and muscle flexibility, along with annual radiological monitoring. Surgical intervention is considered if the curvature exceeds certain thresholds or if the condition is symptomatic.
Scheuermann's disease is a growth-related dystrophy of the spine that leads to painful thoracic kyphosis. It is characterized by an abnormal curvature of the spine that does not conform to normative values and is visible in the sagittal plane.
The two types of hyperkyphosis are postural hyperkyphosis, which is reducible and corrects with posture adjustments, and irreducible hyperkyphosis, as seen in Scheuermann's disease, which is not correctable by posture changes.
Physical activity is encouraged for children with scoliosis as it does not worsen the condition and can help maintain a healthy muscular environment. Engaging in sports can improve muscle mass and reduce stiffness.
Early diagnosis of scoliosis is crucial and should occur before puberty, ideally before the age of 10. This allows for timely intervention and monitoring to prevent progression of the deformity.
The Risser test evaluates the growth stage of a child by assessing the ossification of the iliac crest. It helps determine the risk of scoliosis progression based on skeletal maturity.
Surgical intervention for scoliosis is indicated when the curvature exceeds 45 degrees in the thoracic region or 35 degrees in the lumbar region, especially if there is a risk of further progression or significant symptoms.
Untreated scoliosis can lead to complications such as respiratory issues, especially if the Cobb angle exceeds 70 degrees, and chronic pain due to structural instability of the spine.
The position of the pelvis significantly influences spinal curvatures; for instance, an anteriorly tilted pelvis can lead to increased lumbar lordosis, while a posterior tilt may reduce it.
MRI is utilized in scoliosis evaluation when surgical intervention is considered, particularly to identify associated neurological anomalies or in atypical cases with complex deformities.
Scoliosis can be associated with neurological symptoms, particularly in cases where there are underlying conditions such as neurofibromatosis. These symptoms necessitate thorough evaluation and potential imaging.
Scoliosis typically manifests during childhood, with the most common age range for onset being between 10 and 16 years, coinciding with the growth spurts of puberty.
Monitoring scoliosis progression is essential to determine the need for intervention. Regular assessments help track changes in curvature and inform treatment decisions.
A common misconception is that asymmetrical sports, such as tennis or fencing, worsen scoliosis. However, engaging in sports is beneficial and does not negatively impact the condition.
Children with mild scoliosis often have a favorable prognosis, especially if diagnosed early and monitored regularly. Many may not require treatment and can lead normal, active lives.
