ABSTRACT
Objective:
To define the relationship between radiological and functional outcomes of AIS more than10 years follow-up.
Methods:
22 AIS patients were reviewed retrospectively. Cobb angles were measured from full-length spinal radiography at preoperative, postoperative, mid-term and longterm follow-up. Correction rate and correction loss rate were calculated. The SRS-30 questionnaire form was filled by the patients at the final follow-up examination. Results were compared with the Mann Whitney U test and unpaired t-test. Non-parametric correlation analytical test was performed with the Spearman test. p<0.05 considered as statistically significant.
Results:
There were 15 female and 7 male with the mean age of 14.5. The mean followup was 35.8 and 134 months for mid-term and final follow-up. The mean fusion levels were 10.4 and the average of last instrumented vertebra was L 1.8. Major curvatures were corrected from 53.1° to 19.7° with a 63.6% correction rate. According to the SRS- 30 questionnaire form, the mean pain, function and activity, self-image appearance, mental health, and satisfaction scores were 4.16 ± 0.29, 4.43 ± 0.28, 4.15 ± 0.31, 3.84 ± 0.30, and 4.15 ± 0.44 at mid-term and 3.96 ± 0.52, 4.22 ± 0.38, 4.35 ± 0.22, 4.14 ± 0.36, and 4.10 ± 0.34 at final follow-up, respectively. While the mental health scores improved statistically (p=0.0214), the pain (p=0,043) and the activity (p=0.038) scores deteriorated and the satisfaction score (p=0.64) remained stable in time. A significant relationship was found between the final cobb angle and pain (p = 0.044, Rho = -0.407). When the SRS-30 results were evaluated among themselves, there was a significant correlation between function and self-image (p= 0.005, Rho = 0.547), also function and pain (p= 0.038, Rho = 0.532).
Conclusion:
For the surgical treatment of adolescent idiopathic scoliosis, posterior instrumentation and spinal fusion surgery is an efficient and successful method with patient satisfaction, curvature correction, and low complication rates after more than ten years follow-up.
