OBJECTIVE This study describes the 5 years' results of the Sciatica trial focused on pain, disability, (un)satisfactory recovery and predictors for unsatisfactory recovery. DESIGN A randomised controlled trial. SETTING Nine Dutch hospitals. PARTICIPANTS Five years' follow-up data from 231 of 283 patients (82%) were collected. INTERVENTION Early(More)
The effectiveness of surgery in patients with sciatica due to lumbar disc herniations is not without dispute. The goal of this study was to assess the effects of surgery versus conservative therapy (including epidural injections) for patients with sciatica due to lumbar disc herniation. A comprehensive search was conducted in MEDLINE, EMBASE, CINAHL,(More)
UNLABELLED Femoral component rotation from a total knee prosthesis can be determined by either a measured resection technique or a balanced gap technique. With the balanced gap implantation technique, femoral component rotation can vary freely within the restrictions produced by soft tissue structures. Because internal rotation might cause patella problems,(More)
PURPOSE Odontoid fractures are the most common cervical spine fractures in the elderly. As the population ages, their incidence is expected to increase progressively. The optimal treatment of this condition is still the subject of controversy. The objective of this review is to summarize and compare the outcome of surgical and conservative interventions in(More)
INTRODUCTION Despite an increasing implantation rate of interspinous process distraction (IPD) devices in the treatment of intermittent neurogenic claudication (INC), definitive evidence on the clinical effectiveness of implants is lacking. The main objective of this review was to perform a meta-analysis of all systematic reviews, randomized clinical trials(More)
BACKGROUND AND PURPOSE Outcome measurement has been shown to improve performance in several fields of healthcare. This understanding has driven a growing interest in value-based healthcare, where value is defined as outcomes achieved per money spent. While low back pain (LBP) constitutes an enormous burden of disease, no universal set of metrics has yet(More)
STUDY QUESTION Is interspinous process device implantation more effective in the short term (eight weeks) than conventional surgical decompression for patients with intermittent neurogenic claudication due to lumbar spinal stenosis? SUMMARY ANSWER The use of interspinous implants did not result in a better outcome than conventional decompression, but the(More)
PURPOSE The primary goal of this study was to assess the difference in active flexion between patients with a mobile versus a fixed bearing, cruciate retaining, and total knee arthroplasty. The study was designed as a randomised controlled multi-centre trial. METHODS Participants were assigned to interventions by using block-stratified, random allocation.(More)
BACKGROUND Various surgical and non-surgical treatments for lumbar spinal stenosis (LSS) are widely adopted in clinical practice, but high quality randomised controlled trials to support these are often lacking, especially in terms of their relative benefit and risk compared with other treatment options. Therefore, an evaluation of agreement among(More)
BACKGROUND In the search for better surgical treatment of chronic low-back pain (LBP) in the presence of disc degeneration, total disc replacement has received increasing attention in recent years. A possible advantage of total disc replacement compared with fusion is maintained mobility at the operated level, which has been suggested to reduce the chance(More)
