摘要

Purpose

To evaluate the effectiveness and safety of anterior scoliosis correction (ASC) in patients over 40 years of age.

Methods

This prospective study included 29 patients (mean age 46.6 ± 8.8 years) with idiopathic or adult spinal deformity and a Cobb angle > 30°, who underwent ASC. The follow-up two to five years. Outcomes assessed were Cobb angle correction, quality of life (ODI, SRS-22, SF-36), and postoperative complications.

Results

The mean Cobb angle correction was 59% (from 52.5° to 21.3°). At final follow-up (2.8 ± 1.1), a slight increase to 24.0° was observed, mainly due to curve subsidence. No complications occurred in 62% of patients. Subsidence > 5° was noted in 17% (n = 5), and loss of correction > 15° in 3% (n = 1). One patient experienced persistent pain managed conservatively. Higher risk of subsidence was associated with age > 50 years and preoperative Cobb angle > 50°. Quality of life improved across all measures: ODI decreased from 45% to 32%, SF-36 increased from 50 to 65, and SRS-22 declined slightly from 3.9 to 3.7 in patients with tether settling.

Conclusion

ASC demonstrates high effectiveness and acceptable safety for scoliosis correction in patients over 40 years. Subsidence is the primary adverse event, warranting further investigation and careful patient selection.
