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
The aim of this study was to evaluate the time course of changes
in parameters of diffusion tensor imaging (DTI) such as fractional
anisotropy (FA) and apparent diffusion coefficient (ADC) in patients
with symptomatic lumbar disc herniation. We also investigated the
correlation between the severity of neurological symptoms and these parameters. A total of 13 patients with unilateral radiculopathy due to herniation
of a lumbar disc were investigated with DTI on a 1.5T MR scanner
and underwent micro discectomy. There were nine men and four women,
with a median age of 55.5 years (19 to 79). The changes in the mean
FA and ADC values and the correlation between these changes and the
severity of the neurological symptoms were investigated before and
at six months after surgery. Aims

Aims. The purpose of this study was to investigate the risk of additional surgery in the lumbar spine and to describe long-term changes in patient-reported outcomes after surgery for

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
