Percutaneous vertebroplasty (PVP) is an interventional technique to increase the strength of the vertebral body or restore the shape of the vertebral body, relieve pain and inactivate tumors by injecting bone cement into the vertebral lesion either directly or after the formation of the vertebral body through a special puncture device under the guidance of imaging equipment.
The mechanism of action is to increase the strength of the vertebral body through the mechanical reinforcement of the bone cement; and to relieve pain by inactivating tumor cells and killing nerve cells through the exothermic reaction of the bone cement polymerization.
Indications
1.Compression fracture of osteoporosis
2.Vertebral hemangioma
3.Myeloma
4, primary and metastatic tumors of the vertebral body
5, benign tumors of the vertebral body: such as eosinophilic granuloma, vertebral body lymphoma leading to vertebral body collapse, etc.
Contraindications.
1, uncorrected coagulation disorders and bleeding constitution
2, allergic to the drugs used
The significance of percutaneous vertebroplasty in osteoporosis
The common symptom caused by osteoporosis is painful vertebral compression fracture, which is mostly seen in elderly patients, who used to be treated with medication and bed rest, but long-term bed rest can lead to complications, among which the reduction of exercise after bed rest can aggravate osteoporosis and easily recur vertebral compression fracture, forming a vicious circle. Vertebroplasty can rapidly relieve pain and increase the strength of the vertebral body, restore daily activities, avoid further aggravation of osteoporosis, and improve the quality of life.
Features of percutaneous vertebroplasty
1.Minimally invasive and painless, no need for incision.
2.Good efficacy and fast results.
3.Low complications and low cost.
Typical cases.
Severe compression fracture of vertebral body due to osteoporosis, painful
Percutaneous puncture of a special needle for bone cement into the compressed vertebral body
The pain disappears immediately after the bone cement is injected
