STUDY DESIGN A retrospective study was conducted to review the complication of cage migration in posterior lumbar interbody fusion (PLIF) with the Bagby and Kuslich method. OBJECTIVE To review and analyze cage migration in spondylolytic spondylolisthesis treated with PLIF using paired BAK cages. SUMMARY OF BACKGROUND DATA PLIF with cages has been(More)
BACKGROUND CONTEXT Disc degeneration is a major reason for low back pain and can be caused by apoptosis. The prevention of apoptosis using mesenchymal stem cells (MSCs) may lead to new treatments for low back pain. Previous studies have reported that transplanted MSCs can proliferate and differentiate into cells expressing some of the major phenotypic(More)
Ghrelin, a 28-amino acid peptide, is mainly secreted by the stomach. Ghrelin has been shown to have neuroprotective effects. However, whether ghrelin protects the spinal cord from ischemia/reperfusion (I/R) injury is unknown. To investigate this, 60 rats were randomly divided into three different groups: the sham group (n = 20), the vehicle group (n = 20),(More)
One of the consequences of osteoporotic vertebral compression fractures (OVCFs) is progressive collapse of the fractured osteoporotic vertebral body. This can lead to spinal kyphosis that may cause restriction of respiratory function. The balloon kyphoplasty procedure can reduce kyphosis and relieve the pain. There are few studies that have appropriate data(More)
Our objective was to study the changes in respiratory function of patients with osteoporotic vertebral compression fractures (OVCFs) after vertebroplasty and kyphoplasty. Thoracic kyphotic angle, local kyphotic angle, pain scores and pulmonary function parameters were measured in 38 older women with OVCFs before, three days after and three months after(More)
BACKGROUND It has been well recognized that malnutrition causes wounds to heal inadequately and incompletely. Malnutrition is often observed in the elderly, and it appears to be more severe in patients with hip fracture than in the general aging population. Few prospective studies give a detailed account of the identification and classification of(More)
Patients with nonunion of osteoporotic vertebral compression fractures that are refractory to conservative treatments have persistent back pain, progressive vertebral body collapse and kyphosis, and mobility of the fracture. Although many previous reports have reported vertebral compression fractures treated by balloon kyphoplasty, few data is available on(More)
OBJECT The authors undertook a study in patients with traumatic central cord syndrome (TCCS) who underwent surgical intervention. They retrospectively assessed the motor score improvement and functional status and identified prognostic predictors of improvement. METHODS Between March 1999 and May 2004, 49 patients with TCCS were surgically treated. Motor(More)
PURPOSE To evaluate the clinical efficacy, especially the pain reduction, of vertebroplasty and balloon kyphoplasty in the treatment of osteoporotic vertebral compression fractures (OVCFs). METHODS Eighty-six patients with OVCFs were treated with vertebroplasty or balloon kyphoplasty. All patients were followed up for seven-36 months. Visual analog scale(More)
BACKGROUND CONTEXT Although several authors have already reported on the high local recurrence rate of sacral chordomas after surgical resection, there are no reports on the risk factors for recurrence after resection when combined with preoperative tumor-related blood vessel embolism by digital subtraction angiography (DSA) technique.
