Most osteoporotic vertebral fractures (OVFs) can be treated successfully with conservative methods. In about 10% of patients, nonunion develops and warrants surgical management with minimally invasive procedures such as vertebroplasty and kyphoplasty. Nevertheless, for patients with nonunion fractures that involve the posterior vertebral body wall,(More)
OBJECTIVE To investigate the effects of insulin-like growth factor 1(IGF-1) and ethanol (EtOH) on the changes in the osteoblast proliferation and the osteoblast function under the normal serum concentration and serum starvation. METHODS The osteoblasts harvested from the SD rat calvaria were incubated in the following six conditions according to the(More)
OBJECTIVE To summarize the recent minimally invasive approach for cervical spondylotic radiculopathy (CSR). METHODS The recent literature at home and abroad concerning minimally invasive approach for CSR was reviewed and summarized. RESULTS There were two techniques of minimally invasive approach for CSR at present: percutaneous puncture techniques and(More)
OBJECTIVE To study the technique and effect of adjunctive cancellous screw in treatment of intertrochanteric fractures with dynamic hip screw (DHS) fixation. METHODS Between April 2004 and August 2007, 33 patients with intertrochanteric fracture were treated with DHS fixation and adjunctive cancellous screw. There were 13 males and 20 females, aging 43-82(More)
OBJECTIVE To investigate and compare the effects of restoring and maintaining the cervical curvature and height of the fused segment by using three different anterior cervical plate systems. METHODS From January 2002 to June 2004, 122 patients underwent anterior cervical decompression, autogenous iliac bone graft and plate fixation. Of the 122 patients(More)
To establish a minimally invasive rat model of lumbar intervertebral disc degeneration (IDD) to better understand the pathophysiology of the human condition. The annulus fibrosus of lumbar level 4-5 (L4-5) and L5-6 discs were punctured by 27-gauge needles using the posterior approach under C-arm fluoroscopic guidance. Magnetic resonance imaging (MRI),(More)
Osteoporotic vertebral compression fractures (OVCFs) are common in the elderly population and often involve the thoracolumbar vertebrae. Clinical symptoms of OVCFs include severe pain, loss of vertebral height, progressive kyphosis and increased mortality. Jack vertebral dilator kyphoplasty is a recently developed OVCFs treatment modality, with few(More)
