Percutaneous vertebroplasty has been applied widely to treat bone metastases. The injected cement may strengthen the affected bone to prevent pathological fractures and relieve the pain. Moreover, the thermal reaction (70°C) due to polymerisation of cement also contributes to tumour destruction. The cement dose and diffusion pattern may be significant factors for the treatment efficacy, which can be affected by the inner pressure of the metastases. The investigators will apply a rotary cutter to destroy the structure of metastases to alleviate the pressure in the metastases. Then, more cement will be injected, which may effectively interdigitates with the surrounding bone and generate more thermo to kill the tumor cells.

Percutaneous vertebroplasty is now a common procedures of patients with acute osteoporotic vertebral compression fractures in medical units all over China, but the efficacy and essentialit...
Vertebroplasty is a procedure used to stabilize broken vertebrae, the bones that form the spine. This study will evaluate the effectiveness of vertebroplasty for the treatment of fractures...
The VITTA trial is a randomized, controlled, single-blinded, cross-over trial comparing percutaneous vertebroplasty with facet block in patients with acute (
The aim of this study is to evaluate the efficacy of carrying out early vertebroplasty procedure, compared to the standard conservative treatment (corset), in order to prevent residual def...
The purpose of this study is to determine whether percutaneous vertebroplasty is able to improve long-term quality of life in patients with pain secondary to osteoporotic vertebral fractur...
Percutaneous vertebroplasty consists of percutaneous injection of polymethylmethacrylate (PMMA) via a transpedicular approach for the treatment of collapsed osteoporotic or metastatic vertebrae. Even ...
Percutaneous vertebroplasty (PVP) and kyphoplasty (KP) are minimally invasive treatment options for VCFs due to malignancy.
The aim of the current study was to use a Bayesian network meta-analysis to evaluate the relative benefits and risks of balloon kyphoplasty (BK), percutaneous vertebroplasty (PVP), and non-surgical tr...
The Cochrane vertebroplasty review of April 2018 was replaced with an updated version in November 2018 to address complaints of errors in analysis. The updated version continues to misrepresent the ev...
Vertebral augmentation is among the current standards of care to reduce pain in patients with vertebral fractures (VF), yet a lack of consensus regarding efficacy and safety of percutaneous vertebropl...
Percutaneous excision of a herniated or displaced intervertebral disk by posterolateral approach, always remaining outside the spinal canal. Percutaneous nucleotomy was first described by Hijikata in Japan in 1975. In 1985 Onik introduced automated percutaneous nucleotomy which consists in percutaneous aspiration of the nucleus pulposus. It is carried out under local anesthesia, thus reducing the surgical insult and requiring brief hospitalization, often performed on an outpatient basis. It appears to be a well-tolerated alternative to surgical diskectomy and chymopapain nucleolysis.
A family of percutaneous techniques that are used to manage CORONARY OCCLUSION, including standard balloon angioplasty (PERCUTANEOUS TRANSLUMINAL CORONARY ANGIOPLASTY), the placement of intracoronary STENTS, and atheroablative technologies (e.g., ATHERECTOMY; ENDARTERECTOMY; THROMBECTOMY; PERCUTANEOUS TRANSLUMINAL LASER ANGIOPLASTY). PTCA was the dominant form of PCI, before the widespread use of stenting.
Surgical removal of large KIDNEY CALCULI by means of a percutaneous nephroscope which is passed into the KIDNEY PELVIS through a track created in the patient's back.
Excision, in part or whole, of an intervertebral disk. The most common indication is disk displacement or herniation. In addition to standard surgical removal, it can be performed by percutaneous diskectomy (DISKECTOMY, PERCUTANEOUS) or by laparoscopic diskectomy, the former being the more common.
Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization.
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
Pain is defined by the International Association for the Study of Pain as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage”. Some illnesses can be excruci...
