Finite element analysis of biomechanical effects of mineralized collagen modified bone cement on adjacent vertebral body after vertebroplasty
نویسندگان
چکیده
Objective: To investigate whether mineralized collagen modified polymethyl methacrylate (MC-PMMA) bone cement impacts the implanted vertebral body and adjacent segments feasibility of biomechanical properties compared with common in treatment osteoporotic compression fractures (OVCF). Methods: A healthy volunteer was selected to perform a three-dimensional reconstruction T11-L1 establish corresponding finite element model spine, changes stress distribution different types were biomechanically analyzed groups by applying quantitative loads. Results: The similar between two under various conditions. Conclusion: Mineralized had advantages promoting regeneration, good biocompatibility, transformability, coupling, support strength not inferior PMMA cement, indicating it has development prospects potential.

0319 - Effects of Bone Cement Volume and Distribution on Vertebral Body Stiffness Recovery after Vertebroplasty
Introduction Vertebroplasty is a new therapeutic method which by way of filling bone cement in the vertebral body stabilizes the vertebra. This technique requires a relatively short and less invasive surgery, and has produced excellent short-term clinical results in terms of pain relief . Biomechanical studies have shown that cement augmentation can stabilize the damaged vertebral body in terms...
متن کاملEffect of Bone Cement Volume and Stiffness on Occurrences of Adjacent Vertebral Fractures after Vertebroplasty
OBJECTIVE The purpose of this study is to find the optimal stiffness and volume of bone cement and their biomechanical effects on the adjacent vertebrae to determine a better strategy for conducting vertebroplasty. METHODS A three-dimensional finite-element model of a functional spinal unit was developed using computed tomography scans of a normal motion segment, comprising the T11, T12 and L...
متن کاملCement Leakage into Adjacent Vertebral Body Following Percutaneous Vertebroplasty
Percutaneous vertebroplasty (PV) is a minimally invasive procedure for osteoporotic vertebral compression fractures that fail to respond to conventional conservative treatment. It significantly improves intolerable back pain within hours, and has a low complication rate. Although rare, PV is not free of complications, most of which are directly related to cement leakage. Because of its associat...
متن کاملAdjacent vertebral failure after vertebroplasty. A biomechanical investigation.
Vertebroplasty, which is the percutaneous injection of bone cement into vertebral bodies has recently been used to treat painful osteoporotic compression fractures. Early clinical results have been encouraging, but very little is known about the consequences of augmentation with cement for the adjacent, non-augmented level. We therefore measured the overall failure, strength and structural stif...
متن کاملVertebroplasty: cement leakage into the disc increases the risk of new fracture of adjacent vertebral body.
BACKGROUND AND PURPOSE Patients successfully treated with vertebroplasty often return with new pain caused by a new vertebral body fracture. The new fractures often are adjacent to the vertebral bodies that were initially treated. In our clinical work, we have observed that cement leakage into the disk increases the risk of new fracture of the adjacent vertebral body. This study analyzed the ri...
