This retrospective analysis included 43 patients with cervical spinal cord injury without radiological abnormality. Seven potential factors were assessed: age, sex, external force strength causing damage, duration of disease, degree of cervical spinal stenosis, Japanese Orthopaedic Association score, and physiological cervical curvature. A model was established using multiple binary logistic regression analysis. The model was evaluated by concordant profiling and the area under the receiver operating characteristic curve. Bootstrapping was used for internal validation. The prognostic model was as follows: logit(P) =-25.4545 + 21.2576 VALUE + 1.2160SCORE-3.4224 TIME, where VALUE refers to the Pavlov ratio indicating the extent of cervical spinal stenosis, SCORE refers to the Japanese Orthopaedic Association score(0–17) after the operation, and TIME refers to the disease duration(from injury to operation). The area under the receiver operating characteristic curve for all patients was 0.8941(95% confidence interval, 0.7930–0.9952). Three factors assessed in the predictive model were associated with patient outcomes: a great extent of cervical stenosis, a poor preoperative neurological status, and a long disease duration. These three factors could worsen patient outcomes. Moreover, the disease prognosis was considered good when logit(P) ≥-2.5105. Overall, the model displayed a certain clinical value. This study was approved by the Biomedical Ethics Committee of the Second Affiliated Hospital of Xi'an Jiaotong University, China(approval number: 2018063) on May 8, 2018.展开更多

We discuss our results, comparing this procedure (from a technical point of view) with the muscle-preserving interlaminar decompression (MILD) and the unilateral approach for bilateral decompression (ULBD). Clinical and outcome data of 62 consecutive patients were reviewed, using the Visual Analogue Scale for both low back pain (LBP) and legs pain and the Oswestry Disability Index (ODI) for the degree of disability. Mean age was 68.88 ± 9.54 years and mean follow-up (FU) was 16.38 ± 11.12 months. A statistically significant improvement of LBP, legs pain and ODI was globally observed. At latest FU, patients with multilevel lumbar spinal stenosis significantly improved all scores and patients with spondylolisthesis significantly decreased their disability. No major complications occurred. Two cerebrospinal fluid (CSF) collections were treated conservatively. No wound infection occurred. No progression of spondylolisthesis was observed. No reoperation was needed. Although efficacious in patients with lumbar spinal stenosis, MILD and ULBD can have both some limitations. MILD has been found to decrease lumbar function in multilevel decompression (increasing sagittal translation and lumbar lordosis probably due to the removal of half of the spinous processes) and ULBD shows some disadvantages due to the difficulty of manipulating instruments through a small portal and the inadequate decompression due to a minimal exposure. The minimal invasive bilateral interlaminar decompression (in this technique, the access is bilateral but the supraspinous and interspinous ligaments and the spinous processes are preserved) allows wide access (bilateral exposure) with minimal invasiveness and very low morbidity in patients with lumbar spinal stenosis at one or more levels.展开更多

In the present study, we established a rat model of acute spinal cord injury by cerclage. The cerclage suture was released 8 or 72 hours later, to simulate decompres-sion surgery. Neurological function was evaluated behaviorally for 3 weeks after surgery, and tumor necrosis factorα immunoreactivity and apoptosis were quantiifed in the region of injury. Rats that underwent decompression surgery had significantly weaker immunoreactivity of tumor necrosis factorα and signiifcantly fewer apoptotic cells, and showed faster improvement of locomotor function than animals in which decompression surgery was not performed. De-compression at 8 hours resulted in signiifcantly faster recovery than that at 72 hours. These data indicate that early decompression may improve neurological function after spinal cord injury by inhibiting the expression of tumor necrosis factorα.展开更多

It is characterized by increased bone resorption and the compensatory formation of new bones. The increased bone conversion and remodeling lead to the incrustation of woven bones and lamellar bones and finally result in the expansion, loosening, and excessive vascularization of the affected bones, rendering them susceptible to deformity and fracture. Paget's disease occurs much more commonly in Anglo-Saxons than in Asians and Africans.展开更多

文摘Cervical spondylotic myelopathy is the main cause of non-traumatic spinal cord injury,with chronic static and/or dynamic compressive spinal cord injury as the unique pathogenesis.In the progression of this condition,the microvascular network is compressed and destroyed,resulting in ischemia and hypoxia.The main pathological changes are inflammation,damage to the blood spinal cord barriers,and cell apoptosis at the site of compression.Studies have confirmed that vascular regeneration and remodeling contribute to neural repair by promoting blood flow and the reconstruction of effective circulation to meet the nutrient and oxygen requirements for nerve repair.Surgical decompression is the most effective clinical treatment for this condition;however,in some patients,residual neurological dysfunction remains after decompression.Facilitating revascularization during compression and after decompression is therefore complementary to surgical treatment.In this review,we summarize the progress in research on chronic compressive spinal cord injury,covering both physiological and pathological changes after compression and decompression,and the regulatory mechanisms of vascular injury and repair.
