Risk Factors for Bone Cement Displacement After Percutaneous Kyphoplasty in Osteoporotic Vertebral Fractures: A Retrospective Analysis.

BACKGROUND Bone cement displacement (BCD), which has received increasing attention from scholars, is a serious complication following vertebroplasty in patients with osteoporotic vertebral fractures (OVFs), and percutaneous kyphoplasty (PKP) might promote its occurrence. However, few studies have systematically explored the risk factors of BCD after PKP. This research aimed to study the risk factors for BCD following PKP.

Biomechanical Effects of Different Spacing Distributions Between the Cemented Superior Boundary and Surgical Vertebral Superior Endplates After Percutaneous Vertebroplasty for Osteoporotic Vertebral Compression Fractures: A Three-Dimensional Finite Element Analysis.

Objective: Patients with osteoporotic vertebral compression fractures (OVCF) treated with vertebroplasty (PVP) are experiencing an increasing number of problems such as pain recurrence, mainly due to recompression fractures of the operated vertebral body within a certain period of time after the operation, which is closely related to the distribution of intraoperative bone cement. The aim of this study is to investigate the effect of different spacing distributions between the upper boundary of the cement and the upper endplate of the operated vertebra on the biomechanics of the operated vertebra after percutaneous vertebroplasty for OVCF using finite element analysis (FEA).

Methods: One patient with L1 vertebral body OVCF was selected, and computed tomography (CT) of the thoracolumbar segment was performed.

Development of patient-tailored preoperative assessment of percutaneous vertebroplasty.

Percutaneous vertebroplasty (PVP), a minimally invasive surgery technique, has become the common treatment for osteoporotic vertebral compression fractures (OVCF). The complications of PVP will lead to severe damage to spinal neuro systems due to bone cement leakage. A patient tailored preoperative assessment approach was developed to reduce the risks of complications in this study.

Is it safe to treat osteoporotic burst thoracolumbar fracture using percutaneous vertebroplasty? A minimum of 5-year follow-up study.

Background Context: Percutaneous vertebroplasty for the treatment of osteoporotic burst fractures remains controversial. A previous study has shown that an osteoporotic burst fracture with asymptomatic spinal canal compromise is not a contraindication for percutaneous vertebroplasty.

Purpose: To determine whether these outcomes persist over a long term, we continued to observe patients in their short-term study over a long-term period.

Low pelvic incidence as a risk factor for vertebral recollapse after percutaneous vertebroplasty in the thoracolumbar region.

Background Context: Percutaneous vertebroplasty (PVP) is an effective procedure for treatment of osteoporotic vertebral compression fractures (OVCFs). Recollapse of the cemented vertebrae is not unusual and the thoracolumbar junction is the most common region. Nevertheless, not all patients suffering from OVCFs in this region develop recollapse after PVP.

Vertebral augmentation: How we do it.

Vertebral augmentation consists of minimally invasive techniques indicated in the treatment of vertebral compression fractures (VCFs). These compression fractures cause vertebral body height loss and consequent significant pain and are most frequently the result of osteoporosis, cancer metastasis, or trauma. The deleterious effects of VCFs often compound, as greater load-bearing stress is transferred to the remaining healthy vertebrae.

Keeping it "straight": how to do spinal tumor ablation with vertebral augmentation.

This technical review provides a comprehensive overview of spinal tumor ablation and vertebral augmentation. These percutaneous minimally invasive procedures offer significant survival and palliative pain relief benefits for patients with pathological vertebral fractures. Vertebral augmentation, which includes vertebroplasty and kyphoplasty, involves injecting cement into fractured vertebral bodies to restore height.

Towards optimized biopsy use in vertebral compression fractures: integrating risk assessment for better clinical decision-making.

Purpose: Tissue biopsy is the gold standard for differentiating osteoporotic vertebral compression fractures from malignant lesions.

Methods: A total of 100 elderly patients with osteoporotic spinal fractures, treated between August 2019 and July 2021, were divided into two groups: PVP (research group, n=50) and conservative treatment (control group, n=50). Outcome measures, including injured vertebrae, pain levels, and treatment outcomes, were retrospectively analyzed.

Vertebral Augmentation for Osteoporotic Vertebral Compression Fractures: What is the Current Evidence Pro and Con?

Osteoporotic vertebral compression fractures can be quite challenging to treat, especially since they often occur in older adults and can be associated with significant morbidity and mortality. The standard treatment for these fractures has been medical management, as many of these patients are not candidates for open surgery. Vertebral augmentation procedures have emerged as another treatment option.

Percutaneous Vesselplasty for the Treatment of Vertebral Osteoporotic Collapse Fractures.

A 78-year-old woman with vertebral compression fractures (VCFs) and chronic back pain was the subject of this case study. To treat symptomatic VCFs, less invasive procedures such as balloon kyphoplasty and vertebroplasty were developed. Vertebroplasty involves injecting polymethylmethacrylate (PMMA) into the vertebral body to mechanically stabilize it.

Endovascular treatment of a large bone cement pulmonary embolism: Case report.

We report a case of endovascular treatment of bone cement embolism after percutaneous vertebroplasty. The patient underwent percutaneous vertebroplasty for acute L1 compression fracture. Two weeks later, the patient developed symptoms of pulmonary embolism.

Contact between leaked cement and adjacent vertebral endplate induces a greater risk of adjacent vertebral fracture with vertebral bone cement augmentation biomechanically.

Background Context: Adjacent vertebral fracture (AVF) is a frequently observed complication after percutaneous vertebroplasty in patients with osteoporotic vertebral compressive fracture (OVCF). Studies have demonstrated that intervertebral cement leakage (ICL) can increase the incidence of AVF, but others have reached opposite conclusions. The stress concentration initially increases the risk of AVF, and dispersive concentrated stress is the main biomechanical function of the intervertebral disc (IVD).
