Risk factor analysis for re-collapse of cemented vertebrae after percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP)

Abstract

Patients with low BMD, or undergoing PKP, or receiving a low volume of injected cement might have a high risk of re-collapse in surgical vertebrae.

Teriparatide Associated with Fewer Refractures and Higher Body Heights of Cemented Vertebrae after Vertebroplasty: A Matched Cohort Study

“…The inherent risk factors are low BMD 1 (T score < −2.2), old age 1 , loss of preoperative ABH 1 , a history of other fractures 34 , a greater local KA and a greater sagittal index 35 , and glucocorticoid-induced osteoporosis 36,37 . The procedure-related risk factors are receiving KP 38 , a lower volume of injected cement 38 , significant ABH restoration 2,4,5 , and solid lump filling cement 2 . Moreover, vertebral bone marrow integrity assessed through quantitative preprocedural MRI is associated with refracture 3 .…”

Efficacy analysis of percutaneous pedicle screw fixation combined with percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fractures with kyphosis

“…The cases after PKP were particularly serious, which might be the result of different contact between bone cement surfaces in PKP balloons. There are many reasons for vertebral height loss after vertebral augmentation, for example, the severity of osteoporosis, the choice of surgical methods, the different surgical approaches, the different degrees of preoperative vertebral compression, the different distributions of bone cement, the different amounts of bone cement injection, or the existence of intravertebral cleft and other reasons [16][17][18][19][20][21][22][23]. Therefore, vertebroplasty alone is not appropriate for the treatment of OVF with severe compression and kyphosis.…”

A novel and convenient method to evaluate bone cement distribution following percutaneous vertebral augmentation

“…In addition, cytotoxicity and heat generation of bone cement also play a role in pain relief of patients received vertebral augmentation [9][10][11] . The amount of bone cement used can influence risk of various complications after vertebral augmentation [12][13][14][15][16][17][18][19][20][21] . Injection of excessive bone cement tends to induce new fractures of adjacent vertebral bodies and may increase the leakage rate [12][13][14][15] , while too little bone cement can result in insufficient filling, which can fail to relieve the pain rapidly 15,16 and easily induce re-collapse of the treated vertebrae [17][18][19] .…”
