Background. Surgical site infection following spine surgery is associated with increased morbidity, mortality and increased cost for the health care system. The reported pooled incidence is 3%. Perioperative antibiotic prophylaxis is a key factor in lowering the risk of acquiring an infection. Previous studies have assessed perioperative cefuroxime concentrations in the anterior column of the cervical spine with an anterior surgical approach. However, the majority of surgeries are performed in the posterior column and often involve the
Generally, it is considered to be safe in preventing iatrogenic instability if half of the facet joint is left intact during decompression surgeries. By removing half of the facets can we get adequate decompression of the nerve roots? Is there a difference at different levels in the lower lumbar spine? What is the inclination of the facet joint at each level and how does it affect the stability?. Retrospective study. We analysed 200 consecutive magnetic reasonance imaging (MRI) scans of the lumbosacral spine at L3/4, L4/5, and L5/S1 levels. We measured the difference in the distance from midline to the lateral border of the foramen and from midline to the middle of the facet joint at each level on either sides. The angle of the facet joint was also noted. The distance to the foramen from the level of the middle of the facet joints seem to be between 5-6mm lateral at every level. The angle of the facet joints at L3/4 is 35.9°+/−7.4°, while at L4/5 it is 43.2°+/−8.0°, and at L5/S1 it is 49.4°+/−10.1°. In

Aims. Chronic low back pain due to degenerative disc disease is sometimes treated with fusion. We compared the outcome of three different fusion techniques in the Swedish Spine Register: noninstrumented posterolateral fusion (PLF), instrumented posterolateral fusion (IPLF), and interbody fusion (IBF). Patients and Methods. A total of 2874 patients who were operated on at one or two lumbar levels were followed for a mean of 9.2 years (3.6 to 19.1) for any additional
A series of experiments showing how posture affects the
Kinematics characteristics of the spine and pelvis are one measure proposed to assess lumbar dysfunction. To extent our knowledge about this matter we described the relationship between the orientation of the sacrum, in the sagittal plane, at upright position and the differential
We compared magnetic resonance imaging (MRI) scans and plain antero-posterior (AP) and lateral radiographs of 100 randomly selected patients in order to detect segmental abnormalities of the
Summary Statement. Pedicle screws provide robust fixation and rigid immobilization. There has been no attempt to correlate the anatomic dimensions of thoracic and lumbar pedicles with the accuracy of navigated insertion. This study demonstrates that comparable accuracy using this technique. Introduction. Pedicle screws provide robust mechanical fixation, which makes their use attractive; their use enables fixation of the three spinal columns. There remains concern about the potential both for misplacement; various investigators have studied the accuracy of pedicle screw insertions, comparing different techniques. What is not clear, however, is whether there is any relation between the variables of pedicles’ anatomic dimensions, screw dimensions and accuracy. This study aims to elucidate the relationship between these variables. Patients & Methods. We conducted a retrospective review of consecutive pedicle screws that were inserted in the thoracic and
Introduction: Degenerative disc desease is one of the most frequently encountered spinal disorders. The intervertebral disc is a complex anatomic and functional structure, which makes the development of an efficient artificial disc a challenge [. 1. ]. Based on the complexity of the anatomical structures and the nearly unknown loading conditions at the moment only contradictory knowledge exists about the kinematics after TDA and in particular the location of the center of rotation in the human
Aging has been associated with decreases in muscle strength and bone quality. In elderly patients, paravertebral muscle atrophy is accompanied by vertebral osteoporosis. The purpose of this study was to use paravertebral injection of botulinum toxin-A (BTX) to investigate the effects of paravertebral muscle atrophy on
Aims: The purpose of this study is to evaluate the possible utility of a low-cost radiation-free technique for predicting degenerative changes in the
Purpose: This is a prospective study to examine the post-operative self-satisfaction of the patients and the stability of the
