# Posterior Release Surgery Further Improves the Efficacy of Halo-Pelvic Traction in the Treatment of Patients With Severe Spinal Deformity

## TL;DR

Combining posterior release surgery with halo-pelvic traction improves spinal correction in patients with severe spinal deformities.

## Contribution

Demonstrates that posterior release surgery enhances the efficacy of halo-pelvic traction for severe spinal deformity correction.

## Key findings

- Phase I achieved a 31.9% scoliosis correction rate and 23.1% kyphosis improvement.
- Combining posterior release with traction resulted in an overall 48.9% scoliosis correction and 38.0% kyphosis improvement.
- Age, gender, and comorbidities significantly influenced scoliosis correction rates.

## Abstract

Objective: To explore the effect of posterior release surgery combined with halo-pelvic traction in improving spinal deformity and to evaluate the factors affecting the correction rate of scoliosis.

Background: Spinal surgery is the preferred treatment for severe scoliosis and kyphosis, but direct primary corrective surgery carries significant risks and demands. Traction surgery has been shown to improve safety and spinal correction rates. However, traction surgery has a ceiling effect. In recent years, posterior release surgery has emerged as an emerging technique for spinal correction, but further research is needed to improve correction rates for severe scoliosis.

Methods: Fifty-four patients with spinal deformity treated between April 2021 and December 2023 were divided into two treatment phases: a halo-pelvic traction phase (Phase I) and a posterior spinal release followed by a halo-pelvic traction phase (Phase II). The effects of Phase I and Phase II on scoliosis and kyphosis correction were retrospectively evaluated, and statistical analysis was performed to identify factors influencing scoliosis correction rates.

Results: The first-stage scoliosis correction rate was 31.9%, and the kyphosis improvement rate was 23.1%. The second-stage scoliosis correction rate was 25.0%, and the kyphosis improvement rate was 19.5%. The overall scoliosis correction rate was 48.9%, and the kyphosis improvement rate was 38.0%. Statistical analysis showed that age, gender, and comorbidities (rib fusion or spinal fusion) were significant risk factors for scoliosis correction.

Conclusion: Posterior release surgery combined with halo-pelvic traction can significantly improve the correction effect of patients with severe spinal deformity.
