Risk factors for noncontiguous spinal fractures among elderly patients presenting with traumatic spinal fractures: a retrospective case‒control study.

Objective: Risk factors for noncontiguous spinal fractures (NSFs), which are important for early, timely diagnoses and treatments of elderly individuals with traumatic spinal fractures, have not been discussed in depth. Thus, this study aimed to investigate the risk factors for noncontiguous spinal fractures (NSFs).

Methods: The records of 1,415 elderly patients (aged 60 years and over) who presented with TSFs between 2013 and 2019 were retrospectively reviewed.

Single-cell RNA sequencing identifies the expression of hemoglobin in chondrocyte cell subpopulations in osteoarthritis.

In recent years, chondrocytes have been found to contain hemoglobin, which might be an alternative strategy for adapting to the hypoxic environment, while the potential mechanisms of that is still unclear. Here, we report the expression characteristics and potential associated pathways of hemoglobin in chondrocytes using single-cell RNA sequencing (scRNA-seq). We downloaded data of normal people and patients with osteoarthritis (OA) from the Gene Expression Omnibus (GEO) database and cells are unbiased clustered based on gene expression pattern.

Comparison of percutaneous vertebroplasty and conservative treatment for one level thoracolumbar osteoporotic compression fracture in a 3-year study.

The efficacy of Mesh optimized versus standard percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures. Grid optimization (102 cases; 38 men, 64 women aged 67.3 ± 8.

Implementation of a Specific Set of Intraoperative C-Arm Fluoroscopy Terminologies in Percutaneous Vertebroplasty.

Objective: Percutaneous vertebroplasty (PVP) is currently the primary minimally invasive surgical approach for treating vertebral compression fractures caused by senile osteoporosis. The current existing problem is the lack of research on the application of a specific set of intraoperative C-arm fluoroscopy terminologies in PVP. Therefore, the purpose of this study is to explore the use of a specific set of intraoperative C-arm fluoroscopic terminologies in PVP in order to increase fluoroscopy accuracy, decrease fluoroscopy frequencies and ray protection, and minimize operation times through rapid preoperative training of surgeons and radiographers.

Efficacy and Safety of a 3D-printed Guide Device During Percutaneous Kyphoplasty for the Treatment of Osteoporotic Vertebral Compression Fractures.

Background: During percutaneous kyphoplasty (PKP) for the treatment of osteoporotic vertebral compression fractures (OVCFs), repeated fluoroscopic images to adjust the puncture needle and inject the polymethylmethacrylate (PMMA) are critical steps. A method to further reduce the radiation dose would be of great value.

Objectives: To assess the efficacy and safety of a 3D-printed guide device (3D-GD) for PKP in the treatment of OVCFs and compare the clinical efficacy and imaging outcomes of traditional bilateral PKP, bilateral PKP with 3D-GD and unilateral PKP with 3D-GD.

O-Arm- and Guide-Device-Assisted Personalized Percutaneous Kyphoplasty for Thoracolumbar Osteoporotic Vertebral Compression Fractures.

With the ageing of the global population, the incidence of osteoporotic vertebral compression fractures (OVCFs) is increasing. To assess the safety and efficacy of O-arm- and guide-device-assisted personalized percutaneous kyphoplasty (PKP) for treating thoracolumbar OVCFs, a total of 38 consecutive thoracolumbar OVCF patients who underwent bilateral PKP assisted with an O-arm and a guide device (O-GD group, = 16) or traditional fluoroscopy (TF group, = 22) from January 2020 to December 2021 were retrospectively reviewed, and their epidemiologic, clinical and radiological outcomes were analysed. The operation time was significantly decreased ( < 0.

Unilateral Percutaneous Kyphoplasty Using a Novel Guide Device for Thoracolumbar Osteoporotic Vertebral Fracture.

Objectives: Unilateral percutaneous kyphoplasty (UPKP) has been effective in reducing the operative time, cement volume, and cement leakage (CL) rate compared with bilateral kyphoplasty. However, no device can help to determine the trajectory during operation, especially the inner inclination angle. To assess the safety and efficacy of a novel guide device (GD) for UPKP in the treatment of thoracolumbar osteoporotic vertebral fractures (TLOVFs).

Combined Application of Grid Body Surface Locator and Preemptive Analgesia in Daytime Vertebroplasty.

Objective: To explore the clinical advantages of grid body surface locator combined with preemptive analgesia in the treatment of osteoporotic lumbar fractures in daytime vertebroplasty.

Methods: A retrospective study was conducted on 120 patients who underwent lumbar vertebroplasty in the Department of Orthopedics of General Hospital of Northern Theater Command from January 2017 to January 2020. According to the preoperative planning and analgesic mode of treatment, they were divided into the daily operation experimental group and the traditional mode control group.

A Comparison between Accurate Unilateral Puncture Paths Planned by Preoperative and Conventional Unilateral Puncture Techniques in Percutaneous Vertebroplasty.

Objective: Comparison of the clinical and radiological effects of precise unilateral puncture pathway prepared by preoperative CT data and traditional unilateral puncture pathway in PVP administration for the treatment of osteoporotic vertebral compression fractures. PVP is a commonly used vertebral augmentation operation for the treatment of painful spinal compression fractures. A percutaneous unilateral approach is routinely used to get access to the vertebral body.
