What this trial studies

This clinical trial evaluates the effectiveness of intervertebral disc release (IDR) in treating Lenke 5 adolescent idiopathic scoliosis (AIS) compared to Ponte osteotomy. It aims to assess improvements in axial vertebral rotation and coronal curve correction, as well as to monitor blood loss, hospital stay duration, and adverse events. Participants aged 10-18 with Lenke 5 AIS will be randomly assigned to receive either IDR or Ponte osteotomy. The study will measure various clinical and radiographic outcomes to determine the superiority of IDR in achieving better correction rates.

Who should consider this trial

Good fit: Ideal candidates are adolescents aged 10-18 diagnosed with Lenke 5 type adolescent idiopathic scoliosis.

Not a fit: Patients with a history of previous corrective surgery or those with congenital scoliosis requiring extensive osteotomy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved surgical outcomes and reduced complications for adolescents with Lenke 5 AIS.

How similar studies have performed: While there have been studies on osteotomy techniques, the specific approach of intervertebral disc release in this context is relatively novel and has not been extensively tested.
