Leg Length Discrepancy and Adolescent Idiopathic Scoliosis: Clinical and Radiological Characteristics

Leg Length Discrepancy and Adolescent Idiopathic Scoliosis: Clinical and Radiological Characteristics

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.

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.

Inclusion Criteria:

• Between December 2018-2020
• Scoliotic patients, who detected LLD
• Ages 10 to 18 years
• Patients who have two or more clinical records at least 6 months apart
• Who accepted to participate in the study.

Exclusion Criteria:

• Neurological disease
• A history of spinal surgery/tumors
• The diagnosis of AIS without LLD or trauma
