Summary
Vertebral body tethering (VBT), a fusion-less scoliosis surgery, shows moderate correction but lacks sufficient data for guidelines. Further research is needed due to the high revision rate and methodological limitations.
Area of Science:
- Spine surgery
- Orthopedics
- Scoliosis treatment
Background:
- Vertebral body tethering (VBT), also known as fusion-less anterior scoliosis correction (ASC), is an emerging surgical option for scoliosis.
- Current data on VBT efficacy and patient selection are limited, with no established guidelines.
Purpose of the Study:
- To systematically review the existing literature on VBT for scoliosis correction.
- To assess the outcomes and limitations of this surgical technique.
Main Methods:
- A systematic review was conducted following PRISMA guidelines.
- Nine studies comprising data from 175 patients undergoing VBT were analyzed.
Main Results:
- The mean vertebral instrumentation was 7.3, with an average surgical time of 230 minutes and blood loss of 153 ml.
- A mean coronal plane correction of 52% was achieved, with no significant sagittal parameter changes.
- The revision rate was 18.9%, and methodological quality was deemed unsatisfactory.
Conclusions:
- Available data are insufficient to establish general indications or guidelines for performing VBT.
- Further high-quality research is required to validate the safety and effectiveness of VBT.
