Overview
Brief Summary
The aim of this retrospective study is to present clinical and radiological features and their relationships for differentiating functional scoliosis due to LLD and LLD concurrent with AIS.
Detailed Description
This study was conducted as a single-center retrospective comparative study on 47 consecutive scoliosis patients detected LLD, aged 10-18 years, between 2018 and 2020. The scoliosis patients with a diagnosis of structural LLD were divided into two groups according to whether there was a concurrent AIS diagnosis or not. Demographic data were recorded. Limb length was clinically measured by direct, indirect evaluation method and new LLD-Scoliometer Test. Cobb degree, axial rotation, internal/external pelvic obliquity and LLD were obtained from posteroanterior spine radiographs measured by two blinded orthopaedic spine surgeons.

Outcomes
Primary Outcomes
Full spine PA radiography
Time Frame: baseline
Posteroanterior whole spine digital X-Ray images were obtained with the patient barefoot, both heels on the floor, and both knees extended in an upright standing position. The digital radiography detector was 350x430 millimeters in size and clearly showed the positions of the femoral heads, the iliac crests, and whole spine. The distance between the X-ray tube and the detector was two meters. All radiographic data such as Cobb degree, axial rotation by Perdriolle and pelvic obliquity were measured by two blinded orthopaedic spine surgeons using Surgimap ® Spine (Nemaris ™ Inc, New York, NY) a validated software
direct evaluation- tape measure
Time Frame: baseline
Limb length was clinically with a tape measure while the patient was in a supine position. For the direct evaluation method, measurements were taken from the anterior superior iliac spine to the medial malleolus.
indirect evaluation- wooden blocks
Time Frame: baseline
indirect evaluation method, wooden blocks of known height were used to evaluate the amount of LLD in standing position.
