NEWLY AVAILABLE, NEWLY APPROVED
Vertebral Compression Fracture System
|
DePuy Spine, Inc. has announced the
worldwide launch of the CONFIDENCE
SPINAL CEMENT SYSTEM™, a novel
treatment for vertebral compression
fractures. The CONFIDENCE System consists
of a proprietary hydraulic-based delivery
system that provides precise placement
of a specially formulated high-viscosity
polymethylmethacrylate (PMMA) bone
cement directly into vertebral bodies
to stabilize fractures and to potentially
reduce pain.
The company wishes to note that the
CONFIDENCE Spinal Cement System is easy
to use and has a very short mixing time.
The dough-like consistency of the CONFIDENCE
High Viscosity Cement provides a controlled,
more even fill than that of low-viscosity
cement.1
CONFIDENCE achieves high viscosity immediately
after mixing and stays at a constant
high viscosity for 9 minutes, allowing
for optimal working time. The high-viscosity
properties of the CONFIDENCE Cement
are designed to allow for interdigitation,
preserving the remaining trabecular
structure of the vertebral body.
The unique hydraulic-based delivery
system allows the high-viscosity cement
to flow easily through a long, thin
introducer needle and into the fracture
site. The system also allows delivery
and control outside the fluoro field,
reducing the surgeon’s exposure
to radiation.

Anterior Lumbar Partial Vertebral Body Replacement Device
|
LDR has begun to market its
ROI-A™ partial vertebral body replacement device following 510(k) clearance
from the United States Food and Drug Administration. The ROI-A™ system
incorporates the innovative verteBRIDGE™ anchoring technology.
The ROI-A™ is a stand-alone implant system with zero-profile, self-locking
anchoring plates designed for initial and long-term stability. The surgical technique
is a direct anterior approach, with the curved anchoring plates inserted along
the sagittal plane, thus requiring no additional exposure to the vertebral bodies.
The ROI-A™ device is made of PEEK-Optima® for biocompatibility and
radiolucency along with tantalum markers for verification of implant positioning.
The system is composed of multiple footprint sizes, lordotic angles, and heights
for optimized fit per anatomical requirements. An innovative inserter holds the
implant, protecting vascular structures and guiding the anchoring plates during
insertion.

PEEK Rod System
|
DePuy Spine, Inc. has launched the EXPEDIUM™ PEEK Rod System, a load-sharing
posterior instrumentation system designed to increase anterior column loading
and support the interbody fusion process in the thoracolumbar spine.
EXPEDIUM PEEK rods shift compressive axial forces from the posterior elements
to the interbody fusion site, more closely reproducing the normal loading characteristics
of the lumbar spine. The EXPEDIUM PEEK Rod System is also said to decrease forces
on the bone screw interfaces compared with more rigid metal rod constructs.
EXPEDIUM PEEK rods are made of PEEK-OPTIMA®, a biocompatible polymer of polyetheretherketone
(PEEK), which, DePuy notes, provides a unique combination of strength and flexibility
for load-sharing spinal instrumentation applications. The material is infused
with barium sulfate, a radiopaque compound that allows surgeons to use standard
x-ray technologies to visualize both the PEEK rod implants and the fusion mass
site without the imaging interference associated with titanium or stainless steel
rods.
EXPEDIUM PEEK rods are available in standard 5.5-mm and 6.35-mm diameters and
feature round geometry, which helps reduce the construct profile compared with
larger-diameter, oval-shaped PEEK rod implants. In addition, EXPEDIUM PEEK rods
are compatible with the EXPEDIUM 5.5 and 6.35 and VIPER™2 Spine Systems supporting
both open and minimally invasive (MIS) approaches. Surgeons now have the freedom
to make intraoperative decisions regarding the use of either titanium or PEEK
Rods without having to utilize 2 separate instrumentation systems.
