Repeated lumbar spine surgery has been associated with inferior clinical outcomes. This study aimed to examine and quantify the impact of this association in a national clinical register cohort. This is a population-based study from the Norwegian Registry for Spine surgery (NORspine). We included 26,723 consecutive cases operated for lumbar spinal stenosis or lumbar disc herniation from January 2007 to December 2018. The primary outcome was the Oswestry Disability Index (ODI), presented as the proportions reaching a patient-acceptable symptom state (PASS; defined as an ODI raw score ≤ 22) and ODI raw and change scores at 12-month follow-up. Secondary outcomes were the Global Perceived Effect scale, the numerical rating scale for pain, the EuroQoL five-dimensions health questionnaire, occurrence of perioperative complications and wound infections, and working capability. Binary logistic regression analysis was conducted to examine how the number of previous operations influenced the odds of not reaching a PASS.Aims
Methods
To evaluate outcome in patients with late onset juvenile scoliosis or adolescent idiopathic scoliosis 15 years or more after Boston brace treatment. 281 of 369 patients (22 men) with late onset juvenile (n=67) or adolescent (n=214) braced at mean 24.7 (range 16-32) years previously, responded to follow-up. Patients answered a standardized questionnaire including demographics, work status, Oswestry Disability Index (ODI) (100 - worst possible), EuroQol (EQ-5D) (1 – best possible), and Scoliosis Research Society - 22 (SRS - 22) (5 - best possible), and had radiological examination.Purpose
Methods
To evaluate comorbidity and health-related quality of life in patients with idiopathic scoliosis. 496 patients treated with Boston brace for idiopathic scoliosis were invited for long-term follow-up. 361 women and 29 men responded. Mean age was 39.2 (4.6) years; mean follow-up time 23.4 (4.3) years. 28 patients had been operated. All patients had radiographs at baseline, brace weaning, and follow-up, and filled in validated self-report questionnaires for evaluation of health-related quality of life.Purpose
