Clinical Effectiveness of Intervertebral Disc Release in Treating Lenke 5 Adolescent Idiopathic Scoliosis

Adolescent idiopathic scoliosis (AIS) poses challenges in achieving optimal three-dimensional correction. While posterior fusion with pedicle screws has shown success, osteotomy techniques, such as Ponte osteotomy, have further improved outcomes. However, residual vertebral rotation remains a concern, impacting long-term complications. Intervertebral disc release (IDR) presents a potential solution to enhance derotation and reduce fusion levels, particularly in Lenke Type 5 AIS. This prospective randomized controlled trial aims to evaluate the clinical effectiveness of IDR in treating Lenke 5 AIS, comparing it to Ponte osteotomy. The study focuses on axial vertebral rotation correction, coronal curve improvement, blood loss, hospital stay, and adverse events. Participants aged 10-18 with Lenke 5 AIS will undergo either IDR or Ponte osteotomy, randomly assigned. Outcome measures include axial rotation correction rate, radiographic parameters, and clinical assessments. A total of 132 participants will be recruited. The IDR technique, through posterior disc removal, presents a promising approach to optimize derotation in Lenke 5 AIS. While offering potential advantages, challenges like limited working space and bleeding risks require careful consideration. The study's findings aim to provide robust clinical evidence, enhancing treatment strategies for Lenke 5 AIS and offering innovative approaches for AIS as a whole.
