    Abstract:
    STUDY DESIGN: Observational. OBJECTIVE: To examine changes in patient-reported two-year postoperative outcomes via the Scoliosis Research Society (SRS)-24 Outcomes Instrument from 2001 through 2015. SUMMARY OF BACKGROUND DATA: Techniques for correction of adolescent idiopathic scoliosis (AIS) have evolved over the years, but it is unclear how these changes have impacted patient-reported outcomes. METHODS: AIS patients with two-year postoperative follow-up from a prospective multicenter registry were divided into three-year groups based on trends in surgical approach and construct type (2010-2014: 52% anterior, 43% posterior hybrids; 2005-2011: 3% anterior, 5% posterior hybrids; 2012-2015: 0% anterior, 0.2% posterior hybrids). Because of the ordinal scale (1-5) and bipolar nature of the response sets for the SRS-24, domain/total scores were categorized as ≤3 (predominantly negative) or 4-5 (predominantly positive). Variables were compared across the three groups. RESULTS: A total of 1,695 patients were analyzed; 172 (2010-2014), 926 (2005-2011), and 597 (2012-2015). Average age was 14.7 ± 2 years, the average primary curve was 55° ± 13°, and the group was primarily female (82%). There was a decline in the rate of positive scores for preoperative pain and self-image across the three groups (p < .05). There was an increase in the rate of positive scores for two-year postoperative self-image after surgery, function after surgery, and satisfaction (p < .05). Decreases in length of hospital stay, blood loss, surgical time, preoperative kyphosis, and postoperative trunk shift were observed (p < .05). Increases were observed in levels fused, preoperative major coronal curve, preoperative rib prominence, preoperative trunk shift, percentage correction of major curve, kyphosis restoration, and the rate of double/triple curves (p < .05). CONCLUSION: The percentage of patients with positive postoperative SRS scores has increased in the modern era, providing evidence that newer surgical techniques are resulting in improved outcomes based on the patients' perspectives. Interestingly, recent patients were more afflicted with negative pain and self-image before surgery.
