Summary Spinal canal areas were measured prospectively in 22 consecutive burst fractures of the thoracolumbar junction, preoperatively, within 1 week postoperatively and 1 year after operation. Preoperative canal encroachment averaged 38% (range 10%–70%) of the estimated original area. The 11 patients with neurological impairment had a significantly more severe initial canal encroachment (mean 48%) than those who were neurologically intact (mean 33%). Postoperatively, canal encroachment had decreased to a mean of 18% (range 0%–62%). Within 12 to 15 months postoperatively, canal encroachment was further reduced by resorption of bone fragments to a mean of 2%. The largest observed remaining encroachment was 29%. The amount of bone resorption correlated significantly with the persistent postoperative encroachment. A critical appraisal of the methods used to assess the pre-fracture canal area revealed that reconstructing the vertebral foramen of the fractured vertebra on CT scans substantially overrated the original area as compared with averaging the canal area of the two adjacent vertebrae. 相似文献

Background Context
The load sharing classification (LSC) laid foundations for a scoring system able to indicate which thoracolumbar fractures, after short-segment posterior-only fixations, would need longer instrumentations or additional anterior supports.Purpose
We analyzed surgically treated thoracolumbar fractures, quantifying the vertebral body's fragment displacement with the aim of identifying a new parameter that could predict the posterior-only construct failure.Study Design
This is a retrospective cohort study from a single institution.Patient Sample
One hundred twenty-one consecutive patients were surgically treated for thoracolumbar burst fractures.Outcome Measures
Grade of kyphosis correction (GKC) expressed radiological outcome; Oswestry Disability Index and visual analog scale were considered.Methods
One hundred twenty-one consecutive patients who underwent posterior fixation for unstable thoracolumbar burst fractures were retrospectively evaluated clinically and radiologically. Supplementary anterior fixations were performed in 34 cases with posterior instrumentation failure, determined on clinic-radiological evidence or symptomatic loss of kyphosis correction. Segmental kyphosis angle and GKC were calculated according to the Cobb method. The displacement of fracture fragments was obtained from the mean of the adjacent end plate areas subtracted from the area enclosed by the maximum contour of vertebral fragmentation. The “spread” was derived from the ratio between this subtraction and the mean of the adjacent end plate areas. Analysis of variance, Mann-Whitney, and receiver operating characteristic were performed for statistical analysis. The authors report no conflict of interest concerning the materials or methods used in the present study or the findings specified in this paper. No funds or grants have been received for the present study.Results
The spread revealed to be a helpful quantitative measurement of vertebral body fragment displacement, easily reproducible with the current computed tomography (CT) imaging technologies. There were no failures of posterior fixations with preoperative spreads <42% and losses of correction (LOC)<10°, whereas spreads >62.7% required supplementary anterior supports whenever LOC>10° were recorded. Most of the patients in a “gray zone,” with spreads between 42% and 62.7%, needed additional anterior supports because of clinical-radiological evidence of impending mechanical failures, which developed independently from the GKC. Preoperative kyphosis (p<.001), load sharing score (p=.002), and spread (p<.001) significantly affected the final surgical treatment (posterior or circumferential).Conclusions
Twenty-two years after the LSC, both improvements in spinal stabilization systems and software imaging innovations have modified surgical concepts and approach on spinal trauma care. Spread was found to be an additional tool that could help in predicting the posterior construct failure, providing an objective preoperative indicator, easily reproducible with the modern viewers for CT images. 相似文献7.

Pain regulation and health-related quality of life after thoracolumbar fractures of the spine 总被引:1,自引:1,他引:0

Fractures of the thoracolumbar spine rank among the severest injuries of the human skeleton. Especially in younger patients
they often result from high-energy accidents. Recently, a shift in paradigm towards more aggressive treatment strategies including
anterior procedures could be observed. However, so far only few data exist reflecting the quality of life (QoL) after such
injuries. The aim of this study was to evaluate medium-term QoL and further to identify factors that influence the clinical
outcome in patients with fractures of the thoracolumbar spine. Data of 906 patients who were treated during a 10-year period
in our institution were evaluated retrospectively. Only patients with single-level traumatic injuries aged between 18 and
65 years without neurological deficits, concomitant injuries of other locations and internal comorbidities were included into
the investigation (n = 204). Three different treatment groups (i.e. non-operative, dorsal and dorsoventral stabilisation) were compared to healthy
controls as well as different pain populations. The QoL was assessed using established questionnaires (SF-36, HFAQ, VAS-Spinescore,
PRQ, and PTSD). Sixty-five percent of the included patients (n = 133) were studied at an average follow-up of 5.3 ± 1.7 years after injury. All treatment groups revealed an identical gender
and age distribution. More severe and unstable injuries were found in the surgical groups associated with higher treatment
costs and a longer inability to work. Compared to healthy controls, QoL was compromised to the same extent in all groups.
Furthermore, all patients treated in this study did significantly better than low back pain individuals with regard to QoL
and pain regulation parameters. In our study, patients with thoracolumbar spine fractures showed a reduced QoL compared to
healthy controls. Thus, patients do not seem to regain their former QoL. However, the level of discomfort was comparably low
in all groups, even in patients with more severe injuries requiring extensive surgery. Overall, outcome and QoL after traumatic
fractures of the thoracolumbar spine rather seem to be determined by the severity of injury than by pain regulation or other
psychosocial factors which is likely the case in low back pain disorders. 相似文献

The most common site of injury to the spine is the thoracolumbar junction which is the mechanical transition junction between the rigid thoracic and the more flexible lumbar spine. The lumbar spine is another site which is more prone to injury. Absence of stabilizing articulations with the ribs, lordotic posture and more sagitally oriented facet joints are the most obvious explanations. Burst fractures of the spine account for 14% of all spinal injuries. Though common, thoracolumbar and lumbar burst fractures present a number of important treatment challenges. There has been substantial controversy related to the indications for nonoperative or operative management of these fractures. Disagreement also exists regarding the choice of the surgical approach. A large number of thoracolumbar and lumbar fractures can be treated conservatively while some fractures require surgery. Selecting an appropriate surgical option requires an in-depth understanding of the different methods of decompression, stabilization and/or fusion. Anterior surgery has the advantage of the greatest degree of canal decompression and offers the benefit of limiting the number of motion segments fused. These advantages come at the added cost of increased time for the surgery and the related morbidity of the surgical approach. Posterior surgery enjoys the advantage of being more familiar to the operating surgeons and can be an effective approach. However, the limitations of this approach include inadequate decompression, recurrence of the deformity and implant failure. Though many of the principles are the same, the treatment of low lumbar burst fractures requires some additional consideration due to the difficulty of approaching this region anteriorly. Avoiding complications of these surgeries are another important aspect and can be achieved by following an algorithmic approach to patient assessment, proper radiological examination and precision in decision-making regarding management. A detailed understanding of the mechanism of injury and their unique biomechanical propensities following various forms of treatment can help the spinal surgeon manage such patients effectively and prevent devastating complications. 相似文献

Health-related quality of life after osteoporotic fractures 总被引:6,自引:0,他引:6
Objective: To estimate the impact of osteoporosis fractures on health-related quality of life (HRQOL) in postmenopausal women. Methods: To compare the impact on HRQOL of different osteoporotic fractures, 600 consecutive women 55–75 years old with a new fracture (inclusion fracture) were invited by mail. After exclusions by preset criteria (high-energy fractures, ongoing osteoporosis treatment, or unwillingness to participate), 303 women were included, 171 (56%) of whom had a forearm, 37 (12%) proximal humerus, 40 (13%) hip, and 55 (18%) vertebral fracture, respectively, and all were investigated and treated according to the current local consensus program for osteoporosis. In addition, HRQOL was evaluated by the SF-36 questionnaire and compared with local, age-matched reference material. Examinations were performed 82 days (median) after the fracture and 2 years later. Results: HRQOL was significantly reduced at baseline regarding all SF-36 domains after vertebral fractures and most after hip fractures, but only regarding some domains after forearm and humerus fracture. After 2 years, improvements had occurred after all types of fractures, and after forearm or humerus fracture, HRQOL was completely normalized in all domains. However, 2 years after hip fracture, HRQOL was still below normal regarding physical function, role-physical and social function, while after vertebral fracture, scores were still significantly lower for all domains, physical as well as mental. Patients with one or more previous fractures before the inclusion fracture had lower HRQOL at baseline and after 2 years, compared with those with no previous fracture. Patients with osteoporosis (T-score <–2.5 in hip or spine) had lower HRQOL than those with normal BMD. Conclusion: Vertebral and hip fractures have a considerably greater and more prolonged impact on HRQOL than forearm and humerus fractures. The number of fractures was inversely correlated to HRQOL. These differences should be taken into account when making priorities in health care programs. 相似文献

The purpose of this study was to quantify the physical and mental health of a diverse adult cohort of patients with osteogenesis imperfecta (OI) utilizing a validated health self-assessment questionnaire (SF-36). In addition, a specific demographic questionnaire and a functional questionnaire were utilized to assess more specifically the physical limitations imposed by osteogenesis imperfecta in adulthood. The results of the SF-36 revealed significantly lower physical function scores compared to the U.S. adult norms. However, the SF-36 mental component scores were equal to the U.S. adult norms. The demographic questionnaire revealed high levels of educational achievement, as well as employment, despite significant physical impairments. The functional questionnaire clearly demonstrated limitations mostly related to ambulation. 相似文献

The effect of surgery and remodelling on spinal canal measurements after thoracolumbar burst fractures 总被引:5,自引:0,他引:5
Bone fragments in the spinal canal after thoracolumbar spine injuries causing spinal canal narrowing is a frequent phenomenon. Efforts to remove such fragments are often considered. The purpose of the present study was to evaluate the effects of surgery on spinal canal dimensions, as well as the subsequent effect of natural remodelling, previously described by other authors. A base material of 157 patients operated consecutively for unstable thoracolumbar spine fractures at Sahlgrenska University Hospital in Gothenburg during the years 1980-1988 were evaluated, with a minimum of 5-years follow-up. Of these, 115 had suffered burst fractures. Usually the Harrington distraction rod system was employed. Patients underwent computed tomography (CT) preoperatively, postoperatively and at follow-up. From digitized CT scans, cross-sectional area (CSA) and mid-sagittal diameter (MSD) of the spinal canal at the level of injury were determined. The results showed that the preoperative CSA of the spinal canal was reduced to 1.4 cm2 or 49% of normal, after injury. Postoperatively it was widened to 2.0 cm2 or 72% of normal. At the time of follow-up, the CSA had improved further, to 2.6 cm2 or 87%. The extent of widening by surgery depended on the extent of initial narrowing, but not on fragment removal. Remodelling was dependent on the amount of bone left after surgery. The study shows that canal enlargement during surgery is caused by indirect effects when the spine is distracted and put into lordosis. Remodelling will occur if there is residual narrowing. Acute intervention into the spinal canal, as well as subsequent surgery because of residual bone, should be avoided. 相似文献

Background The purpose of this trial was to measure the health-related quality of life (HRQL) of gastroesophageal reflux disease (GERD) patients waiting for an antireflux operation.Methods A total of 120 patients waiting for a laparoscopic fundoplication were sent questionnaires measuring their symptoms and quality of life.Results Ninety-five of the patients still needing an operation returned the questionaires and were included in the analysis. Thirty-one of 84 patients (37%) felt that the symptoms had worsened, and 51/90 (57%) were unsatisfied. Thirty percent suffered from throat or airway infections, 25% from swallowing difficulties, 48% from retrosternal pain, and 18% had asthma. The mean GERD HRQL score (0–45) was 21.7 (95% confidence interval, 19.7–23.7). Short Form-36 scores of this population were significantly worse when compared to patients with inguinal hernia or moderate asthma.Conclusions Patients waiting for a fundoplication seem to have a significantly decreased health-related quality of life due to poor symptom control regardless of continuous medical treatment. 相似文献
