Intended Use

VertaPlex HV Radiopaque Bone Cement is indicated for the fixation of pathological fractures of the vertebral body using vertebroplasty or kyphoplasty. It is also indicated for the fixation of pathological fractures of the sacral vertebral body or ala using sacral vertebroplasty or sacroplasty. Painful vertebral compression fractures may result from osteoporosis, benign lesions (hemangioma), and malignant lesions (metastatic cancers, myeloma).

Device Story

VertaPlex HV Radiopaque Bone Cement is a PMMA-based bone cement consisting of a powder component (polymer and barium sulfate) and a liquid monomer component. Components are mixed to initiate polymerization, creating a pourable, injectable material that cures into a hardened acrylic structure. Used by physicians trained in vertebral augmentation and acetabuloplasty to provide long-term load support and bone augmentation for pathological fractures of the vertebral body and sacrum. The device is administered intraoperatively under imaging guidance. The hardened cement stabilizes the fracture site, potentially reducing pain and restoring structural integrity to the affected bone. No software or electronic components are involved.

Clinical Evidence

No clinical trials were performed. Evidence consists of a cadaveric study (n=not specified) comparing long-axis vs. short-axis techniques for sacroplasty to assess cement extravasation. Results showed zero instances of extravasation using either technique when performed with meticulous imaging guidance and post-procedural positioning. Supporting evidence includes an extensive literature review on the safety and efficacy of PMMA in the vertebral body and sacrum.

Technological Characteristics

PMMA bone cement consisting of polymer powder (14g), monomer liquid (9.5ml), and barium sulfate (6g) for radiopacity. Polymerization-based hardening. Sterilization via Ethylene Oxide (EO). No electronic, software, or connectivity components.

Indications for Use

Indicated for fixation of pathological fractures of vertebral body or sacral vertebral body/ala via vertebroplasty, kyphoplasty, or sacroplasty. Patient population includes those with painful vertebral compression fractures due to osteoporosis, benign lesions (hemangioma), or malignant lesions (metastatic cancers, myeloma).

Regulatory Classification

## VII. Non-Clinical

A cadaveric study in support of the expanded indication was completed. entitled: A Study of Extravasation of Stryker® VertaPlex® HV Radiopaque Bone Cement Comparing the Meticulous Intraoperative Long Axis Versus Short Axis Techniques for Sacroplasty in Osteoporotic Cadavers. This cadaveric study was conducted to provide data and guidelines as to the most conservative approach

The word "stryker" is in bold, black, sans-serif font, with a registered trademark symbol to the right of the "r".

for sacroplasty procedures, to mitigate the risk for extravasation in sacroplasty procedures.

No instances of cement extravasation after administration of VertaPlex HV Radiopaque Bone Cement were observed in the cadavers included in this study, using the long-axis technique or the short-axis technique. The results of this cadaveric study demonstrate no difference in the occurrence of cement extravasation after administration of VertaPlex HV Radiopaque Cement between the long- and short-axis techniques when the sacroplasty procedure is performed with meticulous imaging quidance by a physician who is trained and experienced in vertebral augmentation and acetabuloplasty and when careful post-procedural positioning is used.

Risk of extravasation specific to the new expanded anatomical area can be mitigated with the use of the guidance developed through completion of the cadaveric study which established surgical guidelines. These surgical guidelines, established by Stryker, are titled "Surgical Procedure - Long and Short Axis Sacroplasty Techniques with Post-Procedure Positioning and CT Evaluation."

## VIII. Substantial Equivalence Conclusion

There have been no changes to the device since the previous clearance. Minor modifications to the packaging had no impact on the device's fundamental scientific technology or intended use, and yielded no increased risk to safety or effectiveness.

The additional Indications for Use to include the vertebral body and sacrum and sacroplasty procedures are supported by the clinical literature and the cadaveric study report. The cadaveric study vielded information to help mitigate the risk of extravasation with the use of the guidance established by Stryker titled "Surgical Procedure - Long and Short Axis Sacroplasty Techniques with Post-Procedure Positioning and CT Evaluation." In addition, the extensive literature review reveals the safety and efficacy of PMMA when used in the vertebral body and sacrum and in sacral vertebroplasty or sacroplasty procedures.

The information submitted herein supports the substantial equivalence of Stryker® Verteplex® HV Radiopaque Bone Cement for use in the vertebral body and sacrum and in sacral vertebroplasty or sacroplasty procedures.
