Degenerative lumbar spinal stenosis (DLSS) can be treated by several surgical procedures. However, the choice of procedure and use of instrumentation remain controversial. In this retrospective study of 81 patients with DLSS, 43 patients received decompression and posterolateral fusion without instrumentation, and the surgery for 38 patients was(More)
We analyzed the clinical efficacy of the Zero-P implant (Synthes GmbH Switzerland, Oberdorf, Switzerland) in the treatment of single level cervical spondylotic myelopathy. The clinical data of 47 patients with single level cervical spondylotic myelopathy were retrospectively analyzed. Twenty-two patients were treated with a Zero-P implant (Group A) and 25(More)
Increasing numbers of studies support the hypothesis that chordoma arises from notochordal cell rests, although the mechanism awaits further research. Brachyury is the first specific molecule linking chordoma with the notochord, and galectin-3 has been widely used as a marker of notochordal cells. We conducted a histological study of the expression of these(More)
Sacral chordoma is a vessel-rich and infiltrative tumor, but the fundamental knowledge of its biological behavior remains unknown. This study was designed to investigate the expression levels and contributions of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) in the angiogenesis and recurrence of sacral chordoma and their(More)
Recombinant microbial transglutaminase (rMTG) is usually expressed as a soluble zymogen (pro-rMTG) in heterologous expression systems but proteolytic activation of the inactive pro-rMTG is essential. Instead of screening proteases for activating pro-rMTG, we examined an alternative method by introducing a specific cleavage site of enterokinase between the(More)
Ultrasound elastography could be used as a new noninvasive technique for detecting early osteoarthritis. As the first critical step, this study theoretically predicted the excitation power and the measurement errors in detecting cartilage detect. A finite element model was used to simulate wave propagation of elastography in the cartilage. The wave was(More)
The aim of this study is to evaluate an integrated cage and plate device (the plate cage Benezech, PCB) filled with autogenous bone in anterior cervical discectomy and fusion. The fused segment height, lordosis, and fusion were assessed by postoperative radiographic examination at different intervals. Patients were evaluated using Odom's criteria and the(More)
Pre-operative embolization of hypervascular spinal tumors can be helpful in tumour resection; however, few studies have been reported on its effectiveness in sacral tumors. We aimed to investigate the value of surgical excision with pre-operative transarterial embolization for primary sacral tumors and evaluate the long-term follow-up outcomes. Data were(More)
We describe the development of an optimization algorithm for determining the effects of different properties of implanted biomaterials on bone growth, based on the finite element method and bone self-optimization theory. The rate of osteogenesis and the bone density distribution of the implanted biomaterials were quantitatively analyzed. Using the proposed(More)
Osteoporosis is one of the most prevalent skeletal system diseases. It is characterized by a decrease in bone mass and microarchitectural changes in bone tissue that lead to an attenuation of bone resistance and susceptibility to fracture. Vertebral fracture is by far the most prevalent osteoporotic fracture. In the musculoskeletal system, osteoblasts,(More)
