Medical research... so enlightening.

Study design: Multicenter, prospective, consecutive clinical series.
Objective: To report on back pain and its association with patients' perceptions of appearance in a prospective cohort study of children before and after posterior spinal fusion for idiopathic scoliosis.
Summary of background data: Back pain in idiopathic scoliosis has been noted to be reduced following surgery. However, uncertainty over its prevalence before and after operation persists. There is a paucity of data on correlations between patients' perceptions of their appearance and preoperative and postoperative pain.
Methods: We reviewed 1433 patients entered consecutively into the Prospective Paediatric Scoliosis Study (PPSS), a database of children (8-22 yr) undergoing operation for idiopathic scoliosis who have been followed for one and two years (n = 295) with the SRS-22 and SAQ instruments.
Results: Preoperative pain was reported by 77.9% of patients and 44% of surgeons. More preoperative pain correlated with older age (rho = -.140, p = 0.000), greater BMI (rho = -0.168, p = 0.000), larger proximal thoracic curve (rho = -0.086, p = 0.019), and a higher score on the SAQ Appearance (greater perception of spinal deformity, rho = -0.223, p = 0.000) and Appearance Desire scales (stronger desire to change the appearance of their spine, rho = -0.153, p = 0.000).
Pain was reduced at 1 and 2 years after operation (p = 0.0002). Patients who perceived themselves as less deformed (rho = -0.284, p < 0.01) or had less desire to change their spinal appearance (rho = -0.183, p < 0.01) experienced a greater reduction in pain 2 years after operation.
Preoperative analgesic use for back pain was high (28.8%) and remained high at 2 years after operation (29.5%) (p > 0.05).
Conclusions: Back pain affects three-quarters of adolescents with idiopathic scoliosis and is reduced after posterior fusion. Patients who are overweight, older, and have larger proximal thoracic curve magnitudes report more preoperative pain. Patients who view themselves as more deformed tend to have more absolute pain, and less reduction in pain after operation.
Significance: Pain in AIS is high and our results point to an opportunity for better management in the subgroup who are dissatisfied with their appearance.
