The Core Outcome Measures Index (COMI) is a short, multidimensional outcome instrument, with excellent psychometric properties, that has been recommended for use in monitoring the outcome of spinal surgery from the patient's perspective. This study examined the feasibility of implementation of COMI and its performance in clinical practice within a large(More)
Decompression surgery is a common and generally successful treatment for lumbar disc herniation (LDH). However, clinical practice raises some concern that the presence of concomitant low back pain (LBP) may have a negative influence on the overall outcome of treatment. This prospective study sought to examine on how the relative severity of LBP influences(More)
Randomised controlled trials (RCTs) of cervical disc arthroplasty vs fusion generally show slightly more favourable results for arthroplasty. However, RCTs in surgery often have limited external validity, since they involve a select group of patients who fit very rigid admission criteria and who are prepared to subject themselves to randomisation. The aim(More)
BACKGROUND Image guided spinal injections are successfully used in the management of low back pain and sciatica. The main benefit of CT-guided injections is the safe, fast and precise needle placement, but the radiation exposure remains a serious concern. The purpose of the study was to test a new institutional low-dose protocol for CT-guided periradicular(More)
STUDY DESIGN Prospective study with 12-month follow-up. OBJECTIVE To examine how the relative severity of low back pain (LBP) to leg/buttock pain (LP) influences the outcome of decompression surgery for spinal stenosis. SUMMARY OF BACKGROUND DATA Decompression surgery is a common treatment for lumbar spinal canal stenosis, with generally good outcome.(More)
BACKGROUND CONTEXT Recent years have witnessed a shift in the assessment of spine surgical outcomes with a greater focus on the patient's perspective. However, this approach has not been widely extended to the assessment of complications. PURPOSE The present study sought to quantify the patient-rated impact/severity of complications of spine surgery and(More)
The Core Outcome Measures Index (COMI) is a reliable and valid instrument for assessing multidimensional outcome in spine surgery. The minimal clinically important score-difference (MCID) for improvement (MCID(imp)) was determined in one of the original research studies validating the instrument, but has never been confirmed in routine clinical practice.(More)
BACKGROUND Chronic low back pain (CLBP) and chronic neck pain (CNP) have become a serious medical and socioeconomic problem in recent decades. Patients suffering from chronic pain seem to have a higher prevalence of sleep disorders. PURPOSE To calculate the prevalence of sleep deprivation in patients with CLBP and CNP and to evaluate the factors that may(More)
PURPOSE The last few decades have witnessed a paradigm shift in the assessment of outcome in spine surgery, with patient-centred questionnaires superseding traditional surgeon-based assessments. The assessment of complications after surgery and their impact on the patient has not enjoyed this same enlightened approach. This study sought to quantify the(More)
STUDY DESIGN Prospective case report series and detailed description of technique. OBJECTIVES To describe a surgical procedure designed to prevent fracture and cutting-through and pullout of screws in the adjacent segment after multilevel deformity correction in adults. SUMMARY OF BACKGROUND DATA Surgery of adult deformities has a high complication(More)
