Overview

In this project, IDEAL-IQ technology and PDFF and R2 image-based imaging methods are used to analyze the intrinsic relationship between preoperative vertebral bone marrow fat content, magnetic susceptibility properties of bone tissue and bone strength (bone volume and bone mass), to explore the mechanism of vertebral re-fracture after PVP / PKP, and to explore the imaging markers for the risk of postoperative vertebral re-fracture after PVP / PKP. To construct a precise and individualized risk assessment model of vertebral re-fracture after PVP/ PKP by combining clinical risk factors, preoperative quantitative MRI parameters (PDFF, R2) and imaging characteristics, so as to achieve the goal of objectively and accurately evaluating the risk of vertebral re-fracture at the early stage of the postoperative period (1 year).

Eligibility

Inclusion Criteria:

  • Patients diagnosed with osteoporotic vertebral fractures of the thoracic and lumbar level with reference to the 2022 edition of the Osteoporotic Fractures Guidelines (2022 edition);
  • The presence of bone marrow edema or hemorrhage (acute fracture) in the fractured vertebrae is clearly defined by MR examination, and the responsible vertebrae is treated with PVP / PKP;
  • Number of fractured vertebrae: 1-3 vertebral compression fractures (including old fractures).

Exclusion Criteria:

  • History of severe scoliosis, vertebroplasty, or internal spinal fixation;
  • Presence of spinal infection and malignant neoplastic disease;
  • Presence of mental disease, cognitive impairment, or critical illness (e.g., severe cardiac or cerebrovascular disease).

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
