Brief Summary

To examine the relationships between spine coronal alignment and lower limb biomechanical parameters in scoliotic adolescents

Detailed Description

BACKGROUND:

Adolescent idiopathic scoliosis is one of the most common orthopaedic diseases affecting the spine during adolescence. Numerous studies deal with the aetiology of the disease, X-ray morphology and classification of curvatures and how the disorder disrupts the spinal biomechanical balance, however the disorder is a complex three-dimensional deformity that affects the body as a whole, and these effects must not be overlooked. No cross-section studies were found assessing the connection between sagittal or coronal balance and the biomechanical parameters of the lower extremity.

HYPOTHESES:

Null hypothesis There are no statistically significant relationships between spine coronal alignment and lower limb biomechanical parameters in scoliotic adolescents.

RESEARCH QUESTION:

What are the relationships between spine coronal alignment and lower limb biomechanical parameters in scoliotic adolescents?

PURPOSE: To examine the relationships between spine coronal alignment and lower limb biomechanical parameters in scoliotic adolescents

Primary Outcome Measures
NameTimeMethod
Coronal balanceat the enrollment

Coronal balance estimated by the distance between plumb line and central sacral line from Anetroposterior x-ray view assessed by computed radiograph (X-ray computed scanogram )

length of the the tibia and femurat the enrollment

The length (in centimeter) of the Tibia and femur will be assessed by computed radiograph (X-ray computed scan-gram)

lower limb mechanical axis; and mechanical axis deviationat the enrollment

The mechanical axis of the lower limb, also called the Mikulicz line, is drawn by connecting a point in the center of the femoral head to a point in the center of the ankle. The value of the deviation is measured in millimeters and is named mechanical axis deviation (MAD). It will be assessed by computed radiograph (X-ray computed scan-gram).

Cobb's angleat the enrollment

Cobb's angle for dorso-lumbar scoliosis. The angle of the curve apex from D10 to L4 will be assessed by computed radiograph (X-ray computed scanogram)

tibiofemoral angleat the enrollment

The tibiofemoral angle (TFA), or knee angle, is defined as the angle between the anatomical axis of femur with the anatomical axis of tibia. It will be assessed (in degrees) by computed radiograph (X-ray computed scan-gram)

knee joint line convergence angleat the enrollment

The knee joint-line convergence angle (KJLCA) h is the angle made by a tangential line between the femoral condyles and the tibial plateau. It will be assessed (in degrees) by computed radiograph (X-ray computed scan-gram)
