Abnormal anthropometry including comparably lower weight and body mass index (BMI) in the adolescent idiopathic scoliosis (AIS) population is increasingly recognised, however, no study has examined postoperative weight loss or its clinical relevance in these relatively thin patients. This study aimed to assess perioperative nutritional status as well as clinically severe involuntary weight loss and its impact on outcomes in patients with AIS undergoing posterior spinal fusion (PSF). A further objective was to compare preoperative anthropometric measurements of the current AIS cohort with healthy controls. ⋯ This study demonstrated that clinically severe postoperative weight loss >10%, identified in almost one-third of this AIS cohort, was associated with significantly increased wound infection incidence. Early detection and prevention of severe postoperative weight loss in patients with AIS who undergo spinal fusion may be beneficial in reducing wound infection risk. This study confirms a body of literature indicating the significantly lower weight and BMI in patients with AIS compared with healthy controls.

One single factor cannot by itself predict curve progression accurately. The aim of this study is to determine multiple related factors in predicting the progression of scoliosis in girls with adolescent idiopathic scoliosis (AIS) treated with bracing. ⋯ This study suggests that Risser sign, the magnitude of the major curve at pre-brace, apical vertebral rotation, and the spinal length increasing velocity are important factors to predict progression in the girls with AIS. Risser sign cannot predict the progression of scoliosis accurately unless combined with other related parameters.

To compare patient outcomes and complication rates after different decompression techniques or instrumented fusion (IF) in lumbar spinal stenosis (LSS). ⋯ As already demonstrated in the literature, decompression in patients with LSS is a very effective treatment. Despite better patient outcomes after laminectomy in combination with IF, caution is advised due to higher rates of surgical and general complications and consequent required measures. Based on the current study, laminotomy or laminectomy, rather than hemilaminectomy, is recommendable for minimum relevant pain relief.

To determine the static and dynamic radiological findings characteristic of symptomatic foraminal stenosis. ⋯ A large segmental range of motion in sagittal plane of L5-S1 and posterior instability of L5 are risk factors for symptomatic L5-S1 foraminal stenosis. These dynamic radiological findings support the diagnosis of symptomatic foraminal stenosis.
