Purpose: This study aimed to evaluate the clinical effects of percutaneous vertebroplasty (PVP) combined with postoperative radiotherapy (RT) in the treatment of spinal metastases.
Methods: Nine patients (4 males and 5 females, mean age 59.56 years) with painful pathologic compression vertebral fractures caused by metastatic cancers of the spine (5 thoracic levels, 8 lumbar levels) were admitted to our hospital between July 17, 2016 and September 25, 2018. All patients were treated with PVP via bilateral pedicle approach combined with postoperative RT to treat metastatic lesions of the centrum. The clinical records of the patients were retrospectively analyzed. Patients' demographic features and medical conditions including the Visual Analogue Scale (VAS), Oswestry Disability Index (ODI) and Imageology data were observed.
Results: Patients' mean VAS scores decreased from 8.67 ± 0.50 preoperatively to 1.78 ± 0.83 at 6 months after PVP. Moreover, the mean ODI score decreased from 74.07 ± 13.15 preoperatively to 31.87 ± 10.00 at 6 months after PVP. Significant improvement in the degree of pain and dysfunction among the enrolled patients were observed. Furthermore, the metastatic carcinoma lesion within the vertebral body was well controlled according to imaging.
Conclusion: PVP in conjunction with postoperative RT is a good treatment strategy for vertebral compression fractures caused by metastases.

Background: No studies have evaluated the impact of the cement distribution as classified on the basis of the fracture bone marrow edema area (FBMEA) in magnetic resonance imaging (MRI) on the efficacy of percutaneous vertebral augmentation (PVA) for acute osteoporotic vertebral fractures.
Methods: The clinical data of patients with acute, painful, single-level thoracolumbar osteoporotic fractures were retrospectively analyzed. The bone cement distribution on the postoperative radiograph was divided into 4 types according to the distribution of the FBMEA on the preoperative MRI.

Osteoporotic vertebral compression fractures (OVCFs) can be painful. Percutaneous kyphoplasty (PKP) aims at strengthening the vertebra and reducing pain, but efficacy can vary among patients. The purpose of this study was to establish a risk prediction model for pain relief following PKP in patients with OVCF.

The rising incidence of osteoporotic vertebral compression fractures (OVCF) has increased the demand for precise treatments like robot-assisted percutaneous vertebroplasty (PVP), especially for conditions like Kümmell's disease that require high surgical accuracy. However, the traditional tracer fixation method has certain limitations. This study aimed to compare the safety and clinical efficacy of a modified tracer fixation technique with the traditional fixation method in robot-assisted percutaneous vertebroplasty (PVP) for Kümmell's disease.

Background: Multiple myeloma (MM) is a hematological malignancy characterized by bone marrow infiltration and osteolytic tumor formation. Despite advancements in the treatment of this disease, MM remains incurable and often leads to complications, such as multiple myeloma bone disease (MMBD). Surgical intervention is frequently necessary to manage symptoms associated with bone disease, including pain and fractures.

Background: Percutaneous vertebroplasty (PVP) is a common surgical method for osteoporotic vertebral compression fracture (OVCFs). The puncture method and location of the puncture needle can directly affect bone cement distribution in the vertebra. This retrospective study aimed to compare the clinical efficacy and safety of PVP using the cross-puncture and bilateral conventional puncture for the treatment of Genant grade 0-1 OVCFs.
