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)
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 (MCIDimp) was determined in one of the original research studies validating the instrument, but has never been confirmed in routine clinical practice.(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)
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 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)
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)
OBJECT The contemporary assessment of spine surgical outcome primarily relies on patient-centered reports of symptoms and function. Such measures are considered to reduce bias compared with traditional surgeon-based outcome ratings. This study examined the agreement between patients' and surgeons' ratings of outcome 1 year after spine surgery. METHODS The(More)
Patient-orientated questionnaires are becoming increasingly popular in the assessment of outcome and are considered to provide a less biased assessment of the surgical result than traditional surgeon-based ratings. The present study sought to quantify the level of agreement between patients’ and doctors’ global outcome ratings after spine surgery. 1,113(More)
Spinal injection procedures can be performed blindly or, more accurately, with fluoroscopic or computed tomography (CT) guidance. Radiographic guidance for selective nerve root blocks and epidural injections allows an accurate needle placement, reduces the procedure time and is more secure for the patient, especially in patients with marked degenerative(More)
Despite the good general patient acceptance, high patient comfort, safety and precision in the needle placement, exposure to radiation in computed tomography (CT)-guided spinal interventions remains a serious concern, and is often used to argue against its use. The aim of this study was to determine the technical possibilities of reducing the radiation dose(More)
