Study Design. Single blind randomized study. Objectives. To compare the effectiveness of lumbar instrumented fusion with cognitive intervention and exercises in patients with chronic low back pain and disc degeneration.Summary of Background Data. To the authors' best knowledge, only one randomized study has evaluated the effectiveness of lumbar fusion. The Swedish Lumbar Spine Study reported that lumbar fusion was better than continuing physiotherapy and care by the family physician.Patients and Methods. Sixty-four patients aged 25-60 years with low back pain lasting longer than 1 year and evidence of disc degeneration at L4 -L5 and/or L5-S1 at radiographic examination were randomized to either lumbar fusion with posterior transpedicular screws and postoperative physiotherapy, or cognitive intervention and exercises. The cognitive intervention consisted of a lecture to give the patient an understanding that ordinary physical activity would not harm the disc and a recommendation to use the back and bend it. This was reinforced by three daily physical exercise sessions for 3 weeks. The main outcome measure was the Oswestry Disability Index.Results. At the 1-year follow-up visit, 97% of the patients, including 6 patients who had either not attended treatment or changed groups, were examined. The Oswestry Disability Index was significantly reduced from 41 to 26 after surgery, compared with 42 to 30 after cognitive intervention and exercises. The mean difference between groups was 2.3 (Ϫ6.7 to 11.4) (P ϭ 0.33). Improvements inback pain, use of analgesics, emotional distress, life satisfaction, and return to work were not different. Fearavoidance beliefs and fingertip-floor distance were reduced more after nonoperative treatment, and lower limb pain was reduced more after surgery. The success rateaccording to an independent observer was 70% after surgery and 76% after cognitive intervention and exercises. The early complication rate in the surgical group was 18%.Conclusion. The main outcome measure showed equal improvement in patients with chronic low back pain and disc degeneration randomized to cognitive intervention and exercises, or lumbar fusion. Lumbar fusion rates have increased greatly over the past 20 years, but the rates vary from country to country. 1 Fusion rates appear to vary markedly among individual surgeons, among small and large geographic regions in the nation, and between the United States and England. 2 Surgical investigations and interventions account for as much as one third of the health care costs for spinal disorders, but the scientific evidence for most procedures is still unclear. 3 The effect of using instruments, such as pedicle screws and cages, compared with pure osseous fusion has been compared in six randomized studies. 3 Only one of these studies reported a higher success rate in the instrumented group, but this was not a strictly randomized study, and the surgeon evaluated the outcome himself. The 1997 Volvo Award Winner concluded that lumbar posterolateral fusion with pedicle screw...

BackgroundEarly diagnosis of idiopathic scoliosis allows for observation and timely initiation of brace treatment in order to halt progression. School scoliosis screening programs were abolished in Norway in 1994 for lack of evidence that the programs improved outcome and for the costs involved. The consequences of this decision are discussed.ObjectivesTo describe the detection, patient characteristics, referral patterns and treatment of idiopathic scoliosis at a scoliosis clinic during the period 2003–2011, when there was no screening and to compare treatment modalities to the period 1976–1988 when screening was performed.MethodsPatient demographics, age at detection, family history, clinical and radiological charts of consecutive patients referred for scoliosis evaluation during the period 2003–2011, were prospectively registered. Patients were recruited from a catchment area of about 500000 teenagers. Maturity was estimated according to Risser sign and menarcheal status. Severity of pain was recorded by a verbal 5-point scale from no pain to pain at all times. Physical and neurological examinations were conducted. The detector and patient characteristics were recorded. Referral patterns of orthopedic surgeons at local hospitals and other health care providers were recorded. Patient data was obtained by spine surgeons. Treatment modalities in the current period were compared to the period 1976–1988.ResultsWe registered 752 patients with late onset juvenile and adolescent idiopathic scoliosis from 2003–2011. There were 644 (86%) girls and 108 (14%) boys. Mean age at detection was 14.6 (7–19) years. Sixty percent had Risser sign ≥ 3, whilst 74% were post menarche with a mean age at menarche of 13.2 years. Thirty-one percent had a family history of scoliosis. The mean major curve at first consultation at our clinic was 38° (10°-95°). About 40% had a major curve >40°. Seventy-one percent were detected by patients, close relatives, and friends. Orthopaedic surgeons referred 61% of the patients. The mean duration from detection to the first consultation was 20(0–27) months. The proportion of the average number of patients braced each year was 68% during the period with screening compared to 38% in the period without screening, while the proportion for those operated was 32% and 62%, respectively ( p=0.002, OR 3.5, (95%CI 1.6 to 7.5).ConclusionIn the absence of scoliosis screening, lay persons most often detect scoliosis. Many patients presented with a mean Cobb angle approaching the upper limit for brace treatment indications. The frequency of brace treatment has been reduced and surgery is increased during the recent period without screening compared with the period in the past when screening was still conducted.

Aim  Rett syndrome is a neurodevelopmental disorder starting in early childhood with devastating consequences both on the brain and on systemic neurons. Scoliosis is a common complication in most of these patients. The aim of the study was to describe the prevalence of scoliosis, classify spinal deformity, and evaluate the association between disability and scoliosis in patients with Rett syndrome. Method  Twenty‐nine female patients, mean age 14 years 8 months (range 4y 10mo–33y) were included. Outcome parameters were the Barthel Index for evaluation of function, pain, analgesics, and radiological evaluation of the spine including curve size (Cobb’s method) and curve type. None of the patients had surgery before assessment. Results  Twenty‐five (87%) patients had radiographically verified scoliosis. The median curve was 41° (range 15–77). The curve was classified as C‐shaped (neuromuscular) in 16 patients and double curve‐shaped in nine. Function was poorer in patients with C‐shaped curve (p<0.01). Walking on a level surface (r=0.9) and the ability to ascend or descend stairs (r=0.8) were highly correlated with the Barthel Index. Curve size was moderately correlated with function (r=0.5). Interpretation  Function level in females with Rett syndrome measured according to the Barthel Index showed significant correlation to scoliosis curve type. A low score was associated with a C‐shaped curve involving all of the spine and pelvis.

IntroductionThough developed for thoracic insufficiency syndrome, the spinal growth-stimulating potential and the ease of placement of vertical expandable titanium ribs (VEPTRs) has resulted in their widespread use for early-onset spine deformity. Observation of implant-related ossifications warrants further assessment, since they may be detrimental to the function-preserving non-fusion strategy.Patients and methodsRadiographs (obtained pre and post index procedure, and at 4-year follow-up) and the records of 65 VEPTR patients from four paediatric spine centres were analysed. Ossifications were classified as type I (at anchor points), type II (along the central part) or type III (re-ossification after thoracostomy).ResultsThe average age at the index procedure was 6.5 years (min 1, max 13.7). The most prevalent spine problem was congenital scoliosis (37) with rib fusions (34), followed by neuromuscular and syndromic deformities (13 and 8, respectively). Idiopathic and secondary scoliosis (e.g. after thoracotomy) were less frequent (3 and 4, respectively). Forty-two of the 65 (65 %) patients showed ossifications, half of which were around the anchors. Forty-five percent (15/33) without pre-existing rib fusions developed a type II ossification along the implant. Re-ossifications of thoracostomies were less frequent (5/34, 15 %). The occurrence of ossifications was not associated with patient-specific factors.ConclusionsImplant-related ossifications around VEPTR are common. In contrast to harmless bone formation around anchors, ossifications around the telescopic part and the rod section are troublesome in view of their possible negative impact on chest cage compliance and spinal mobility. This potential side effect needs to be considered during implant selection, particularly in patients with originally normal thoracic and spinal anatomy.

Management of scoliosis in young children needs a comprehensive approach because of its complexity. There are many debatable points; however, only serial casting, growing rods (including traditional and magnetically controlled) and anterior vertebral body tethering will be discussed in this article. Serial casting is a time-gaining method for postponing surgical interventions in early onset scoliosis, despite the fact that it has some adverse effects which should be considered and discussed with the family beforehand. Use of growing rods is a growth-friendly surgical technique for the treatment of early onset spine deformity which allows chest growth and lung development. Magnetically controlled growing rods are effective in selected cases although they sometimes have a high number of unplanned revisions. Anterior vertebral body tethering seems to be a promising novel technique for the treatment of idiopathic scoliosis in immature cases. It provides substantial correction and continuous curve control while maintaining mobility between spinal segments. However, long-term results, adverse effects and their prevention should be clarified by future studies. Cite this article: EFORT Open Rev 2020;5:753-762. DOI: 10.1302/2058-5241.5.190087

A total of 221 patients from 21 general practitioners was entered in a double-blind comparative study of spiramycin and doxycycline in the treatment of pneumonia and acute exacerbations of chronic bronchitis. One-hundred-and-five patients were randomized to treatment with spiramycin tablets for 5 1/2 days and 116 patients were randomized to treatment with doxycycline tablets for nine days. The efficacy and side effects of the two treatment regimens were observed. Of the 221 patients included, 191 were acceptable for evaluation, 91 in the spiramycin group and 100 in the doxycycline group. Three patients in the spiramycin group withdrew because of lack of efficacy and one patient in the doxycycline group withdrew because of side effects (feeling unwell and blurred vision). No significant differences in efficacy or safety were found between the two treatments.

This study entails a prospective evaluation of lumbar closing wedge osteotomy for correction of thoracolumbar kyphotic deformity in ankylosing spondylitis. Twenty patients with a median age of 52 years (range, 26-70) underwent follow-up at one year. The lumbar closing wedge osteomtomy was stabilised by metallic rods fixed by transpedicular screws. Outcome measures were quality of life (EuroQol), occiput-to-wall distance, pain, fatigue, complications, technical and radiological evaluation. The technical result was good in 16 and fair in four patients; two had neuropraxia. The deformity was reduced an average of 17 degrees (95% confidence interval 15-25 degrees) at one-year follow-up. Pain during activity, pain at night, and fatigue were significantly reduced. EuroQol improved from 0.42 to 0.69 (p = 0.002) and occiput-to-wall distance from 26 to 18 cm (p = 0.005). Functional outcome was improved after lumbar closing wedge osteotomy in ankylosing spondylitis.
