Object: The objectives of this study were to: 1) describe the incidence and clinical features of intravertebral vacuum phenomenon (IVVP) in a relatively large number of cases; 2) quantitatively evaluate intravertebral instability and determine the factors affecting instability; and 3) evaluate the efficacy of percutaneous vertebroplasty in the treatment of this phenomenon.
Methods: A retrospective review was conducted of the records of 67 patients with IVVP among 652 consecutive cases of osteoporotic compression fracture. Comparisons between the IVVP group and a control group, a stable group, and an unstable group were conducted. Percutaneous vertebroplasty was performed in all patients. There were 67 patients (10.3%) in whom there were 70 vacuum phenomena of the intravertebral space. Intravertebral vacuum phenomena occurred predominantly in the thoracolumbar junction (81%) and in patients with a longer duration of symptoms (10.6 +/- 9.8 months) compared with the control group. Of 59 vertebrae for which flexion-extension radiographs were available, 26 vertebrae were categorized as stable and 33 as unstable. Twenty-one vertebrae (64%) had undergone compression fracture in the unstable group compared with nine (35%) compression fractures in the stable group. There were 28 (85%) fractures of the wedged vertebrae in the unstable group compared with 16 (61%) fractures in wedged vertebrae in the stable group. Percutaneous vertebroplasty was performed with successful clinical outcome.
Conclusions: Intravertebral vacuum phenomenon is more common than has been previously appreciated. The results of this study indicate that biomechanics, not ischemic or avascular theory, may play an important role in pathogenesis of this phenomenon. Percutaneous vertebroplasty was found to be a minimally invasive and effective procedure for the treatment of IVVP.

Background: Machine learning (ML) has been widely applied to predict the outcomes of numerous diseases. The current study aimed to develop a prognostic prediction model using machine learning algorithms and identify risk factors associated with residual back pain in patients with osteoporotic vertebrae compression fracture (OVCF) following percutaneous vertebroplasty (PVP).
Methods: A total of 863 OVCF patients who underwent PVP surgery were enrolled and analyzed.

Article Synopsis
- The study aimed to assess the occurrence of secondary vertebral compression fractures (SVCF) after percutaneous vertebral augmentation (PVA) and to identify associated risk factors for better clinical guidance.
- A retrospective analysis involved 288 PVA cases, categorizing patients into groups based on whether they experienced SVCF during follow-up, while collecting various health and procedural data.
- Results showed a 14.60% incidence of SVCF, with significant risk factors identified, including age, body mass index, fat infiltration in muscles, cement leakage, and procedural techniques, evaluated through statistical analyses.

Based on the characteristics of Kummell's disease (KD) and related anatomical structures of the thoracolumbar spine, a novel bone cement screw system has been designed to effectively avoid the cement loosening and displacement. This experiment aimed to assess the biological effects of the novel bone cement screw system in KD on fresh cadaveric thoracolumbar spine specimens, thereby discussing its potential application value and providing a foundation for clinical implementation. This study employed a total of 50 fresh female adult cadaver specimens.

Article Synopsis
- Osteonecrosis is a condition marked by bone death due to reduced blood flow, seen in various locations and stemming from different causes, like medications and radiotherapy.
- A unique case study is discussed where a 52-year-old woman, undergoing chemotherapy for lymphoma, developed rare multilevel osteonecrosis in her vertebrae, indicating the complexity of the condition.
- The case highlights the need for more research on diagnosing and treating vertebral osteonecrosis, given its rarity and the complications that arise from treatment interactions and lack of standardized protocols.

Article Synopsis
- - Osteoporotic vertebral compression fractures (OVCFs) can lead to ongoing back pain even after treatment, with varying rates of residual pain reported, highlighting the need for more research on risk factors.
- - A systematic review of 19 studies revealed that 16% of patients experience residual back pain (RBP) and 18% have cement leakage post-treatment, with several factors like gender, bone mineral density, and history of fractures linked to RBP.
- - The study emphasizes the importance of understanding RBP's risk factors to help doctors identify high-risk patients and improve treatment strategies, while future research should work on standardizing definitions and patient selection for better outcomes.
