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)
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)
STUDY DESIGN A prospective nonrandomized comparative study. OBJECTIVE To compare the efficacy and safety of kyphoplasty and vertebroplasty for treatment of painful osteoporotic vertebral compression fractures (VCFs) with respect to pain, functional outcome, radiomorphology, cement leakage, and incidence of new adjacent vertebral fracture. SUMMARY OF(More)
OBJECT The nucleus pulposus has been reported to be an immunologically privileged site. The expression of Fas ligand (FasL) on normal and herniated lumbar disc cells has been reported. The relationship between a physiological barrier and the role of FasL has not yet been addressed. To clarify this relationship and to investigate a possible pathogenesis of(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)
To evaluate the clinical efficacy, especially the pain reduction, of vertebroplasty and balloon kyphoplasty in the treatment of osteoporotic vertebral compression fractures (OVCFs). Eighty-six patients with OVCFs were treated with vertebroplasty or balloon kyphoplasty. All patients were followed up for seven–36 months. Visual analog scale (VAS), vertebral(More)
A total of 51 patients who underwent the second open discectomy by fenestration from January 1988 through December 1994, were followed for an average of 146.8 months. The long-term follow-up results were evaluated through direct examinations and questionnaires. At the final follow-up, according to the Macnab classification an excellent and good outcome was(More)
OBJECTIVE To analyze complications associated with posterior lumbar interbody fusion (PLIF) in which two Bagby and Kuslich (BAK) interbody fusion cages were implanted. METHODS A total of 118 patients with spondylolytic spondylolisthesis underwent single-level PLIF using two BAK cages filled with morselized autogenous bone. The major clinical and(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)
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.
