Magnetic resonance imaging (MRI) is frequently performed during follow-up in patients with known lumbar-disk herniation and persistent symptoms of sciatica. The association between findings on MRI clinical outcome controversial.We studied 283 a randomized trial comparing surgery prolonged conservative care for sciatica herniation. Patients underwent at baseline after 1 year. We used 4-point scale to assess disk MRI, ranging from "definitely present" 4 absent." A favorable was defined as...
<b>Objective</b> To assess whether interspinous process device implantation is more effective in the short term than conventional surgical decompression for patients with intermittent neurogenic claudication due to lumbar spinal stenosis. <b>Design</b> Randomized controlled trial. <b>Setting</b> Five neurosurgical centers (including one academic and four secondary level care centers) Netherlands. <b>Participants</b> 203 participants were referred Leiden-The Hague Spine Prognostic Study Group...
Objective This study describes the 5 years’ results of 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 follow-up data from 231 283 patients (82%) were collected. Intervention Early surgery or an intended 6 months conservative treatment. Main outcome measures Scores Roland disability questionnaire, visual analogue scale (VAS) leg back pain a...
A cross-sectional study on baseline data.To translate the Oswestry Disability Index (ODI) version 2.1a into Dutch language and to validate its use in a cohort of patients with chronic low back pain secondary spine care.Patient-reported outcome measures (PROMs) are commonly accepted evaluate interventions. Functional status is an important research. The ODI recommended condition-specific patient-reported measure used functional pain. As yet, no formal translated exists.The was according...
Femoral component rotation from a total knee prosthesis can be determined by either measured resection technique or balanced gap technique. With the implantation technique, femoral vary freely within restrictions produced soft tissue structures. Because internal might cause patella problems, effect of ligament releases on in prospective clinical study was studied. intraoperatively with tensor applied flexion at 150 N 87 knees. Great interpatient variability found; rotation, reference...
