To report the incidence of cancer in a cohort of adolescent idiopathic scoliosis (AIS) patients treated 25 years previously. ⋯ The overall cancer rate in this AIS cohort was 4.3 % which is five times higher than compared to the age-matched Danish population, and endometrial and breast cancer was most frequent. The radiation dose applied to the patients in this study, is comparable to modern equipment. This is to our knowledge the first study to report increased rates of endometrial cancers in a cohort of AIS patients, and future attention is needed to reduce the radiation dose distributed to the AIS patients both pre-operatively and during surgery.

Study of patients with adolescent idiopathic scoliosis. ⋯ A mild positive correlation was identified between sPAP and the coronal Cobb angle of the MT curves. There was no relationship between sPAP and the direction of the curvature.

To investigate whether an optimal upper instrumented vertebra (UIV) tilt angle would prevent 'lateral' shoulder imbalance or neck tilt (with 'medial' shoulder imbalance) post-operatively. ⋯ An optimal UIV tilt might prevent neck tilt with 'medial' shoulder imbalance due to trapezial prominence and but not 'lateral' shoulder imbalance.

Evaluate the relationship between radiological, clinical and perceived waistline asymmetry (WLA) in a sample of idiopathic scoliosis (IS) patients. ⋯ WLA measures proposed in this article are reliable tools to assess WLA. We have found a significant correlation between clinical WLA and skeletal deformity (Cobb angle). WHA is related with MT curve while the RLWAD depends on the TLL curve magnitude and its LEV. We have also found a significant relation between WHA and the patient's perception of the deformity. It seems that WLA is a cosmetic concern to take into account in clinical evaluation of IS patients.

"Simplified Chinese" version of Spinal Appearance Questionnaire (SC-SAQ) for patients with adolescent idiopathic scoliosis (AIS) was available but did not fit for communities using "Traditional Chinese" as their primary language. We developed a traditional Chinese version of SAQ (TC-SAQ) and evaluated its reliability and validity. ⋯ TC-SAQ had good internal consistency and test-retest reliability. Concurrent validity evaluated against the original English version was excellent. TC-SAQ was both reliable and valid for clinical use for AIS patients using traditional Chinese as their primary language.
