Aims. 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. Methods. 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
Background. Percutaneous endoscopic interlaminar discectomy (PEID) has achieved favorable effects in the treatment of
The aims of this study were to determine the rates of surgical complications, reoperations, and readmissions following herniated lumbar disc surgery, and to investigate the impact of sociodemographic factors and comorbidity on the rate of such unfavourable events. This was a longitudinal observation study. Data from herniated lumbar disc operations were retrieved from a large medical database using a combination of procedure and diagnosis codes from all public hospitals in Norway from 1999 to 2013. The impact of age, gender, geographical affiliation, education, civil status, income, and comorbidity on unfavourable events were analyzed by logistic regression.Aims

Introduction: Operations inside the spinal canal are afflicted with a certain number of iatrogenic dural lesions. Incidence figures in the literature vary from 1 to 17% and are mainly based on retrospective studies. The Swedish Spine Register, SweSpine, provides a good possibility to study the incidence in a prospective patient material. Patients and Methods: During 5 years more than 9 000 patients had surgical treatment for
We present our four-year experience with a new minimally invasive method for ambulatory treatment of
Introduction Minimally invasive lumbar discectomy using the METRx™ System (MAST discectomy) has been advocated as an alternative to open microdiscectomy for symptomatic posterolateral
Background. Recently, some studies have focused attention on the possibility that anaerobic pathogens of low virulence could constitute an etiological factor in disc herniation. There have been isolated such strains, predominantly Propionibacterium acne, between 7 and 53% of patients undergoing surgery for disc pathology. According to these studies, patients with anaerobic infections of the disc are more likely to develop Modic changes in the adjacent vertebrae. The aim of this work was to test this hypothesis by growing in specific media the disc material extracted in a series of lumbar discectomy and relating this factor with the presence of pre-intervention Modic changes. Methods. A total of 22 consecutive patients undergoing primary unisegmental discectomy for

The study was founded by The Regional Institute of Health Sciences Research. Background: There is a need for identifying specific subgroups of LBP, Modic changes might be one of these subgroups. The aim is to describe the relationship between a previous herniated disc and the following Modic changes. Methods: 181 patients with radicular pain below the knee, leg pain ≥ 3, duration of leg pain between 2 and 52 weeks, and age between 18 and 65 years were included. The patients were randomized into one of two active conservative treatment regimes lasting eight weeks. All included patients were scanned at baseline and again at 14 months follow-up. All MRI evaluation was carried out by the same experienced radiologist using a validated evaluation protocol. Results: The prevalence of Modic changes type 1 increased more than 3 fold from 9 % at baseline to 29 % at follow-up; type 2 was respectively 14 % and 13 %. In patients with Modic changes at baseline, extremely few reduced in size or disappeared, on the contrary new type 1 changes developed after the herniation. In patients with a normal disc, 0 % developed Modic changes at follow-up, whereas in those with extrusions and sequestrations 56–63%. There exist a strong association between Modic changes and LBP, 67 % of those with Modic changes had LBP compared to 21 % of the patients without, OR 6.1, (p<

In a high-risk technically advanced speciality like spine surgery, detailed information about all aspects of possible complications could be frightening for the patients, and thereby increase anxiety and distress. Therefore, aim of this study was to
Analyze written evidence of the consenting procedure pertaining to (a) nature of operation (b) benefits intended as a result of the operation (c) risks specific to the particular type of operation (c) general risks of spine surgery and anaestheia. Patients’ experiences of information regarding the risk of such complications and how the information affects the patients.
The study had a non-randomized design and patients divided into TWO groups Group A and group B. The patients in the group A received standard information and were consented in a routine way without being given written proforma with all complications. The patients in the group B were given the same information as patients in the control group, with written information about common and rare complications. Patients in both groups were assessed on an ‘impact of events scale’ and hospital anxiety and depression scale immediately before ad after the consent process and again after surgery when they were discharged from the hospital. For comparison of the proportion of Yes and No answers in 2 groups, Fisher’s exact test was used, and for comparison of more than 2 groups, the Chi-square test was used. For graded answers and other ordinal scales, the Mann–Whitney U-test was used for comparison of 2 groups and the Kruskal–Wallis test for comparison of more than 2 groups. Spearman’s test was used when assessing the correlation between 2 variables measured on an ordinal scale.

Purpose. Patients may present with concurrent symptomatic hip and spine problems, with surgical treatment indicated for both. Controversy exists over which procedure, total hip arthroplasty (THA) or lumbar spine procedure, should be performed first, and does the surgeon's area of expertise influence the choice. Materials & Methods. Clinical scenarios were devised for 5 fictional patients with both symptomatic hip and lumbar spine disorders for which surgical treatment was indicated. An email with survey link was sent to 110 clinical members of the Hip Society and 101 experienced spine surgeons in the USA requesting responses to: which procedure should be performed first, and the rationale for the decision with comments. The clinical scenarios were painful hip osteoarthritis and (1) lumbar spinal stenosis with neurologic claudication; (2) lumbar degenerative spondylolisthesis with leg pain; (3)
