The initial correction rate (ICR) has been widely used as a predictor for curve progression in adolescent idiopathic scoliosis (AIS) undergoing bracing treatment. We proposed a new parameter, the initial Cobb angle reduction velocity (ARV), for prediction of curve progression. The purpose of this study was to identify whether the initial ARV was a more effective predictor than ICR for curve progression in AIS patients undergoing brace treatment, and to evaluate the ideal cut-off point of initial ARV for prediction of curve progression. ⋯ The initial Cobb angle reduction velocity serves as a better predictor for curve progression than initial correction rate in braced AIS patients with follow-up interval of 3-6 months. At the second visit following bracing prescription, those AIS patients with reduction velocity in Cobb angle lower than 10°/year have significantly higher risk of curve progression.

Lumbar disc herniation (LDH) in children is rare. Few studies have evaluated the outcome of surgery and none in a prospective study design. ⋯ Operative treatment of LDH in growing individuals leads to very good outcome with high degree of patient satisfaction.

The occurrence of spinal epidural haematoma of 'spontaneous' origin in adults is a well-documented entity, though it is rare in children. In the literature to date, there are few cases of this kind of spontaneous haematoma proven to be due to an underlying vascular abnormality. ⋯ These are the first two such cases described with clinico-pathological correlation.

The purpose of this study was to review the postoperative complications after posterior spinal fusion (PSF) in cerebral palsy (CP) scoliosis and identify the predictive preoperative risk factors. ⋯ This study suggests that G-tube dependence is a predictive risk factor of complications after PSF in CP scoliosis. Children with G-tube need special perioperative care. No other specific preoperative risk factor predicted postoperative complications.

Lumbar spondylolysis, a stress fracture of the pars interarticularis in the lumbar spine, is often precipitated by trauma, but there may be a congenital predisposition to this condition. There have been few studies on spondylolysis in young children, despite their suitability for studies on congenital defects. The aim of this study was to identify the clinical features of lumbar spondylolysis in elementary school age children in order to elucidate its pathogenesis. ⋯ Lumbar spondylolysis in elementary school age children was commonly a terminal-stage bone defect at L5, which was not necessarily related to history of athletic activity and was sometimes asymptomatic. It was often associated with SBO, indicating a possible congenital predisposition. These findings may provide further insight into the pathogenesis of lumbar spondylolysis.
