This study focuses on treating vertebral compression fractures, a condition where bones in the spine collapse. It compares two treatments: vertebroplasty or kyphoplasty using a bone cement called PMMA alone, or PMMA mixed with a special additive, Inossia® Cement Softener. The goal is to confirm if Inossia® Cement Softener, when mixed with PMMA, is safe and effective for strengthening bones weakened by these fractures. The study aims to enroll 150 patients who are eligible for these treatments. The results could help improve care for people with this condition by providing a new treatment option. During the study, participants receive either the standard PMMA treatment or the PMMA treatment with Inossia® Cement Softener. The study then measures the location and timing of any new fractures, comparing those who received the standard treatment to those who received the new combination. This helps determine if the new treatment is as good as, or better than, the current standard. The study also checks for any potential risks or benefits associated with using Inossia® Cement Softener.

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

203 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Criteria

Inclusion Criteria: * Informed consent obtained before any study-related activities (study-related activities are any procedures that would not have been performed during normal management of the patient, i.e. standard of care); * Symptomatic osteoporotic vertebral compression fracture without prior or not responding to medical treatment within 6 months; * Maximum of 1 level of vertebral compression fractures eligible for treatment localized at level Th5 to L5 and verified by MRI or bone scan; * Height reduction of the affected vertebra(e) with an anterior wall compression of not exceeding 60% compared to the nearest normal vertebral body determined by X-ray; * Have pain correlating to the fractured levels requiring regular analgesic intake and/or causing substantial disability of daily life; * Pain score ≥ 40 mm measured by VAS correlating to at least one of the fracture levels (scale 0 - 100 mm) at the screening visit; * Oswestry Disability Index \> 20 (0 - 100 scale); * SF-12PCS Index \< 80 (0 - 100 scale); * Patient with a communicative ability to understand the procedure and participate in the study and comply with the follow up program. Exclusion Criteria: * Patients below 18 years; * Any burst fracture; * Unstable fractures defined by neurological deficit or interspinous process widening as evaluated by the Investigator, as well as kyphosis \> 30°, translation \> 4 mm; * Established or suspected malignancy of the fractured vertebra. Hemangioma of the fractured vertebra; * High energy trauma or clinical diagnosis of herniated nucleus pulposus or severe spinal stenosis as suggested by progressive weakness; * Have neurologic symptoms or deficits, or radiculopathy related to the fractured vertebrae; * Patients with extremely high BMI, i.e. BMI ≥ 40; * Previously treated with vertebroplasty or kyphoplasty; * Patients with concomitant diseases which may be worsened by invasive treatment of the fracture such as e.g. severe cardiopulmonary dysfunction (including aortic aneurysm), as judged by the Investigator * Irreversible coagulopathy or bleeding disorder. Note regarding reversible coagulopathies: Patients on Coumadin or other anticoagulants may participate. Investigators should follow routine practices for perioperative discontinuation and re- initiation of anticoagulants; * Active systemic infection or local skin infection at the puncture site; * Pregnancy or breast-feeding; * Patients with known chemical dependency or drugs or with a medical history of drug abuse; * Patients who are serving prison sentence; * Have participated in another investigational study within 30 days prior to inclusion * Pacemaker * Previous or active radiotherapy affecting the spine

Treatment Groups
Study Objectives

2 intervention groups are designated in this study

This study does not include a placebo group 

Treatment Groups

Group I

Experimental
This group uses a special bone cement called V-Flex, which includes Inossia® Cement Softener. This is being tested as a treatment for vertebral compression fracture.

Group II

Active Comparator
Participants in this group receive the V-Steady treatment, which involves the use of bone cement alone. No additional medications or procedures are included.
