Key MethodWe reviewed the cases of 727 patients with idiopathic scoliosis in whom the initial curve measured from 5 to 29 degrees. The patients were followed either to the end of skeletal growth or until the curve progressed. One hundred and sixty-nine patients (23.2 per cent) showed progression of the curve. The incidence of curve progression was found to be related to the pattern and magnitude of the curve, the patient's age at presentation, the Risser sign, and the patient's menarchal status. We found…

The natural history of adolescent idiopathic scoliosis

There is evidence that the absolute curve magnitude at presentation may be most predictive of progression in the long term, which may unlock novel predictive factors, which are based on the underlying pathogenesis of this disorder.

Progression of the curve in boys who have idiopathic scoliosis.

The prevalence of curve progression was evaluated in 210 boys who had idiopathic scoliosis. A minimum age of eight years, a deformity of at least 10 degrees, and radiographic follow-up of one year or

Assessment of curve progression in idiopathic scoliosis

It is strongly suggested that only a small percentage of scoliotic curves will undergo progression, and the pattern of the curve according to curve direction and sex of the child was found to be a key indicator of which curves will progress.

Curve Progression and Spinal Growth in Brace Treated Idiopathic Scoliosis

The findings indicate the length of the spine measured on subsequent radiographs is an excellent parameter to determine spinal growth and thus an excellent predictor of scoliosis progression.

In the major left thoracic and left lumbar curve types, initial minor curves progressed faster than major curves, and the scoliosis progressed faster in patients with minorThoracic kyphosis.

Scoliosis in patients treated with growth hormone.

It is concluded that growth hormone may increase the risk of progression of scoliosis and the progression is frequently rapid and requires special vigilance by the treating physician.

The impact of residual growth on deformity progression.

Progression risk assessment of idiopathic scoliosis showed that a 30° curve at the beginning of puberty together with 20° to 30° curves with more than 10° of annual curve progression has a 100% risk of progression towards the 45° surgical threshold in these patients.

Factors associated with spinal deformity progression in adolescent idiopathic scoliosis

There is evidence that the absolute curve magnitude at presentation may be most predictive of progression in the long term.

Skeletal age assessment from the olecranon for idiopathic scoliosis at Risser grade 0.

The method of assessing skeletal age from the olecranon allows skeletal maturity to be evaluated in regular six-month intervals during the phase of peak height velocity and is simple, precise, and reliable.

Intervention versus Observation in Mild Idiopathic Scoliosis in Skeletally Immature Patients

It is suggested that pre-menarcheal, skeletally immature patients with mild idiopathic scoliosis, and low vitamin D, BMD, and BMI should be treated, and asymmetric foot biomechanics should be addressed, although nutrition and foot orthoses are regarded to have no role in the management of idiopATHicScoliosis.



Scoliosis: incidence and natural history. A prospective epidemiological study.

A prospective study was carried out of the incidence and natural history of adolescent idiopathic scoliosis in 26,947 students, finding that spontaneous improvement of the curve occurred in 3 per cent and was seen more frequently in curves milder than 11 degrees.

[Prognosis of idiopathic scoliosis].

The Harrington procedure should now be used in all centers of scoliosis, because over 50 degrees surgery is required, because further progression is to be expected.

Nonstandard Vertebral Rotation in Scoliosis Screening Patients: Its Prevalence and Relation to the Clinical Deformity

A total of 6,321 school children screened using Moiré topography in Ottawa in 1979 showed that 39% had rotation of a nonstandard variety, the most common type was rotation extending beyond the end vertebra by more than one level.

Scoliosis: A prospective epidemiological study.

A two and a half-year prospective study carried out to determine incidence rates and distributions of various parameters associated with idiopathic scoliosis found that spontaneous improvement occurred in approximately 22 per cent of those patients followed for an average of one year.

Voluntary school screening for scoliosis in Minnesota.

The experience in Minnesota over the past eight years was reviewed, with an average of one-quarter of a million children being screened yearly, and voluntary scoliosis screening in Minnesota is an efficient and cost-effective program.
