This study was designed to analyze the flow and distribution of polymethylmethacrylate (PMMA) in vertebral body through computer simulation. Cadaveric lumbar vertebrae were scanned through electron beam tomography (EBT). The data was imported into Mimics software to build computational model. Vertebral body center and junction of pedicle and vertebral body were chosen as injection points. Silic...

Introduction: Thermal ablation by microwave (MWA) has proven efficacy in treatment of primary and metastatic cancers. Soft tissue tumors could be ablated completely using MWA. However, bony tissue metastasis particularly spinal vertebral metastasis ablation has not reported yet. Case presentation: A 50 year old male patient with primary diagnosed colon cancer undergone surgical resection of ...

Given the diversity of vertebral morphologies among fishes, it is tempting to propose causal links between axial morphology and body curvature. We propose that shape and size of the vertebrae, intervertebral joints, and the body will more accurately predict differences in body curvature during swimming rather than a single meristic such as total vertebral number alone. We examined the correlati...

Vertebral fractures are a common clinical entity, caused by trauma or related to osteoporosis (benign). Their recognition is especially important in the post-menopausal female population but also important is their differentiation from pathological (malignant) fractures (1). A vertebral fracture is evidenced by vertebral body deformity or reduction in vertebral body height beyond a certain thre...

BACKGROUND AND PURPOSE Percutaneous vertebroplasty is known for its pain-relieving effect. Our purpose was to evaluate its effect on the kyphosis angle, wedge angle, and height of the fractured vertebral body. METHODS We reviewed digital radiographs of 73 vertebral bodies in 53 patients before and after vertebroplasty. We measured the spinal kyphosis angle and the wedge angle of the fractured...

OBJECTIVE To evaluate whether an early bone marrow edema pattern predicts vertebral deformity types and prognosis in osteoporotic vertebral compression fracture (OVCF). METHODS This retrospective study enrolled 64 patients with 75 acute OVCFs who underwent early MRI and followed up MRI. On early MRI, the low SI pattern of OVCF on T1WI were assessed and classified into 3 types (diffuse, globul...

OBJECTIVE To see the safety and efficacy of Percutaneous vertebroplasty in osteoporotic vertebral compression fractures. METHODS This study was conducted at the Department of Neurosurgery, Liaquat National Hospital (LNH) Karachi, Pakistan. Patients with osteoporotic compression vertebral fractures, not responding to conservative treatment and having localized overlying tenderness and MRI evid...
