Bone cement blending and staged injection method in percutaneous vertebroplasty

Abstract

The invention belongs to the technical field of osteoporosis treatment, and particularly relates to a bone cement blending and staged injection method in percutaneous vertebroplasty. The method comprises the following steps: 1, refrigerating bone cement at low temperature; 2, taking out the frozen bone cement, pouring the bone cement powder into the bone cement, pouring the liquid into the bone cement, and uniformly stirring and blending the materials in the same direction; 3, performing stirring by using a blending rod, when the bone cement is gradually changed into a liquid state from a fine sand and water mixture state, timely picking up the bone cement by using the blending rod to observe the state, defining a rod hanging period when the liquid bone cement flows downwards from the blending rod, sucking 3-5 needle tubes with the volume of 1 ml or 5 ml, putting the needle tubes into the brine ice for later use, and reasonably distributing the suction and injection time, and timely employing the stage injection in the toothpaste period, so that the satisfactory perfusion that cement exists in vertebral bone and bone exists in the cement is achieved; the risk of secondary fracture caused by pulmonary embolism, bone cement leakage, excessive perfusion and bone cement lump coalescence can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of osteoporosis treatment, in particular to a bone cement reconciliation staged injection method in percutaneous vertebroplasty. Background technique [0002] With the development of material civilization and social civilization, the trend of population aging is becoming more and more obvious. Osteoporosis is one of the diseases that threaten the health of the elderly in an aging society. According to statistics, about 50% of patients with osteoporosis often lead to vertebral compression fractures (Vertebral Compression Fractures, VCF), and corresponding kyphosis Deformity and chronic low back pain. Vertebral compression fractures can lead to dysfunctional pain that lasts for several months. The clinical manifestations are pain or aggravation when sitting up or lying down. Or avoid this pain, but long-term bed rest has brought fatal complications such as hypostatic pneumonia, deep vein thrombosis, and pulm...

AI Technical Summary

Problems solved by technology

However, the leakage of bone cement in clinical operation is a major problem for orthopedic surgeons in the application of this technology. The leakage of bone cement is the direct cause of severe complications such as spinal cord compression, nerve injury and pulmonary embolism during and after surgery.
