Brief Summary

The present study intends to: 1)establish a multi-center large-sample randomized controlled trial to explore the technical advantages and surgical indications of the novel surgical technique of CLIF correction for ASD compared with the conventional correction strategy; 2)analyze the postoperative clinical and imaging results, and to explore the related complications and preventive measures; 3) establish 2-year follow-up to further quantify the clinical and radiographical outcomes of CLIF correction.

Outcome Measures

Primary Outcomes (1)

  • ODI score

    ODI score is Oswestry Disability Index(0-100), indicating the back pain; the higher score, the greater back pain

    2 year after surgery

Secondary Outcomes (1)

  • SF-36 score

    2 year after surgery

Study Arms (2)

Novel CLIF correction

EXPERIMENTAL

ASD patients with novel CLIF correction

Procedure: CLIF correction

conventional correction strategy

ACTIVE COMPARATOR

ASD patients with conventional correction strategy

Procedure: conventional correction strategy

Interventions

CLIF correction was a novel surgical techqiue of correction of spinal deformtiy with minimal invasive approach

Novel CLIF correction

conventional correction was the classic surgical techqiue of correction of spinal deformtiy with open posterior approach
