The SRS-22 instrument was developed to assess quality of life in adolescent idiopathic scoliosis patients (AIS). The aim of our study was to evaluate the impact of surgical treatment on quality of life in neurologically normal patients with complex spinal deformity of a range of aetiologies using the SRS-22 questionnaire.

We analysed prospectively collected SRS-22 data on 407 consecutive patients (315 females-92 males) treated from 2006–2012 under the care of the senior author. 97.6% of patients had a posterior (PSF), 1.3% an anterior (ASF) and 1.1% an anterior-posterior (A/PSF) spinal fusion. Questionnaires were completed at 4 stages of treatment: preoperatively, 6-months, 12-months and 24-months postoperatively. Other variables included age at surgery, gender, diagnosis and year of surgery. 9 diagnoses were included in the study: 271 patients had AIS; 39 Scheuermann's kyphosis; 31 spondylolisthesis; 16 congenital scoliosis; 13 JIS; 6 IIS; 13 scoliosis associated with intraspinal anomalies; 11 syndromic scoliosis; 7 scoliosis associated with congenital cardiac disease. Mean age at surgery was 15.14±2.07 years. Age at surgery was divided in 3 groups to compare outcomes against previous studies: 10–12, 13–15, and 15–19 years.

Mean total SRS-22 scores for the whole group were: preoperative 3.62±0.66; 6-month 4.12±0.44; 12-month 4.39±0.40; and 24-month 4.52±0.37 (p<0.0001). Individual preoperative scores for the whole group were: function 3.77±0.75; pain 3.7±0.97; self-image 3.14±0.66; mental 3.86±0.77. Mean 24-month postoperative scores for the whole group were: function 4.39±0.42; pain 4.59±0.56; self-image 4.39±0.51; mental 4.43±0.56; satisfaction 4.81±0.40. All changes observed at 2-year follow-up were statistically significant (p<0.0001). Male preoperative total score (3.64±0.66) did not have a significant difference compared to female (3.62±0.66); however 24-month total score improvement was significant, with males (4.62±0.25) performing better than females (4.49±0.39) including satisfaction (p=0.004). Spondylolisthesis patients performed worse preoperatively (2.93±0.26) compared to other diagnoses (p<0.0001); AIS 3.67±0.64, congenital 3.81±0.57, syndromic 3.80±0.54, Scheuermann's 3.48±0.75, JIS 3.90±0.63, scoliosis with congenital cardiac disease 4.04±0.41 or intraspinal anomalies 3.71±0.66, and IIS 3.58±0.80. No change in total and individual scores was observed at 24-month review across diagnoses (p>0.05). There were no significant changes between each year of surgery in the study period and the total values at each stage (p>0.05). There were no significant changes between the 3 age ranges at each stage (p>0.05). Patients undergoing ASF performed significantly better at preoperative function (4.7±0.27) compared to PSF (3.76±0.74) and A/PSF (3.68±0.72), (p=0.19). All values at 2-years were not significant in comparison regarding type of operation (p>0.05).

All individual domains and total SRS-22 scores improved after surgical correction of spinal deformity in our young patient cohort with an incremental change between preoperative, 6-month, 12-month and 24-month postoperative. Our 24-month postoperative outcomes in all diagnoses compare favourably to reported SRS-22 scores in healthy adolescents (function: 4.31±0.54; pain: 4.44±0.67; image: 4.41±0.64; mental health: 3.96±0.81; total 4.26±0.54). We are planning to continue this study with longer follow-up in order to allow comparison of our SRS-22 outcomes after surgical treatment to those obtained in patients treated with bracing or patients who were followed untreated (previous reports SRS-22 total scores: 4.2 for braced patients and 4.1 for observed patients).
