Clinical Trial Controlled Clinical Trial
Outcome scores in degenerative cervical disc surgery.
Forty-six consecutive patients with neck pain and arm radiculopathy were treated with anterior cervical discectomy and fusion. All patients had neurological symptoms corresponding to a herniated disc and/or spondylosis at one or two cervical levels, verified by magnetic resonance imaging. The patients were stabilized with an anterior graft and randomized to either fixation with a CSLP plate or no internal fixation. ⋯ We conclude that the modified Million Index and Oswestry Index are clinically useful tools in the evaluation of outcome after degenerative cervical disc surgery. The clinical benefits of plate fixation were minimal. The outcome after surgery, measured with the Oswestry Index, Million Index and VAS for arm and neck pain, seems to correlate well with the classification of outcome by Odom.

Thirty-nine consecutive patients, 22 male and 17 female with an average age of 37.6 years, with traumatic spondylolisthesis of the axis were reviewed. The cause of injury in 75% of the patients was a road traffic accident. The fractures were classified according to Effendi et al., the type II fractures were further divided into three subgroups: flexion, extension and listhesis injuries. ⋯ However, further distinction of the type II injuries regarding their stability is mandatory. Type II spondylolisthesis injuries are unstable, with a high number of associated injuries, a great potential for neurological compromise and significant complications associated with non-operative treatment. The majority of type II extension and type II flexion injuries can be successfully treated with nonrigid external immobilisation.

Pain in the pelvic joints and lower back, a major problem for pregnant women, has proved resistant to precise measurement and quantification. To develop a classification system, the clinical tests used must be able to separate pelvic from low back pain; they must also have a high inter-examiner reliability, sensitivity and specificity, and preferably be easy to perform. The aim of this study was to describe a standardised way of performing tests for examining the pelvis, and to evaluate inter-examiner reliability, and establish the sensitivity and specificity of 15 clinical tests. ⋯ Five tests showed superior sensitivity. The specificity of the tests was between 0.98 and 1.00, except the value for pelvic topography, which was 0.79. These results show that it is possible to standardise examination and interpretation of clinical tests of the pelvic joints, resulting in a high degree of sensitivity, specificity and inter-examiner reliability.

The goal of this systematic literature review was to determine, for patients with degenerative disc disease, which method of single-level anterior cervical interbody fusion using the anterior approach gives the best clinical and radiological outcome. The number of new techniques for obtaining a solid fusion has increased rapidly, but the rationale for choosing between different techniques is unclear. Randomised comparative studies on anterior cervical interbody fusions were identified in a sensitive Medline, Cochrane and Current Contents database search. ⋯ Good clinical outcome (disability, pain and symptoms) ratings varied from 66% to 82%. A meta-analysis to determine the best method for an anterior interbody fusion could not be performed due to the heterogeneity of the methods reported and because no standard outcome parameter was used. From this systematic literature review, a gold standard for the treatment of degenerative disc disease could not be identified.

The vertebral end-plate is critical for maintaining the health of the intervertebral disc. This paper reviews the literature that relates to end-plate structure and development and describes how disc integrity is affected by changes associated with pathology and aging. A range of studies, including biomechanical, biochemical, surgical and histological is discussed to illustrate the important role of the end-plate in spinal function.
