Purpose

We report on outcomes of surgically versus (vs) non-surgically treated patients with moderate adolescent idiopathic scoliosis (AIS) after minimum of 29 years.

Methods

AIS patients with a follow-up of  ≥ 41 years in the surgical group and  ≥ 29 years in the non-surgical group were included. Patients were treated surgically for primary curves  ≥ 45° vs non-surgically for curves  

Results

In total, 16 patients (8 within each group, 75% females) with a median age of 14 (interquartile range (IQR) 2) years could be included and were followed up after 46 (IQR 12) years. All matched variables were similar for both groups, including the primary curve Cobb angles of 48° (IQR 17°) (surgical) vs 40° (IQR 19°) (non-surgical); p = 0.17). At final follow-up after a median of 47 (IQR 5) years for the surgical and 39 (IQR 19) years for the non-surgical group (p = 0.43), the ODI was similar for both groups (15 (IQR 13) points (surgical) vs 7 (IQR 15) points (non-surgical); p = 0.17) with, however, a primary curve magnitude lower in the surgical compared to the non-surgical group (38° (IQR 3°) vs 61° (IQR 33°); p = 0.01), respectively.

Conclusion

After around 47 and 39 years, respectively, surgical and non-surgical treatment of moderate AIS showed similar subjective outcomes, but with a relevant smaller curve magnitude with surgical treatment.
