Medtronic Finds its Place in the
Orthopedic Market With Knee
Implant Service: 5 Observations
By Megan Wood
D
ublin, Ireland-based Medtronic unveiled its new business
unit, which will offer joint replacement products, according
to Minneapolis/St. Paul Business Journal.
Here are five observations:
1. In preparation for market entrance, Medtronic acquired Minne-
apolis-based Responsive Orthopedics, a startup developing afford-
able implants.
2. The new business unit, Medtronic Orthopedic Solutions, will assist
hospitals in developing and managing bundled payment programs.
3. Medtronic plans to help providers plan procedures as well as of-
fer implants and bleeding-control technology.
4. If Medtronic proves successful in cutting hospital costs, the com-
pany will receive a share of the saved amount.
5. Medtronic plans to launch its knee-implant service in 2017. n
FDA Clears Xtant Medical's
Xsert Lumbar Expandable
Interbody System
By Megan Wood
T
he FDA cleared Belgrade, Mont.-based
Xtant Medical's Xsert Lumbar Expandable
Interbody System. A titanium expandable
interbody device, the Xsert System expands
in-situ.
Xtant offers the system in different size and
lordotic angulations to complement various
patient anatomies. Intended for use at one or
two contiguous levels, the system is designed
to ease insertion techniques as well as provide
implant height adjustability. The Xsert System
is cleared for use with autograft or allograft
bone graft.
Xtant is planning an initial product launch in mid-
2017. n
8 Orthopedic Imaging Technologies to Know:
C-arms, O-arms & G-arms
By Eric Oliver
Here are the eight orthopedic imaging devices
or technologies for spine leaders to know.
C-arm for Orthopedics, GE Health (Chicago).
GE has three orthopedic-based variations on
its popular C-arm machine: the OEC 9900
Elite Mobile C-arm, the OEC 9800 Plus Mobile
C-arm and the OEC Brivo Plus. e 9800 Plus
is marketed as the most widely used mobile
C-arm imaging machine worldwide. e 9800
Plus has 1k by 1k high resolution imaging tech-
nology on its mobile system.
OEC Brivo Plus C-arm, GE Health. e OEC
Brivo Plus is another of GE's C-arm machines.
It features "eagle-eye" technology that allows
for pinpoint imagining. e device also has an
auto adjustment feature which will automat-
ically adjust an image when the anatomy is
off-center. e device produces less radiation
than a regular X-ray.
Arcadis Orbic 3D, Siemens (Erlangen,
Germany). e Arcadis Orbic imaging ma-
chine is a C-arm machine with an isocentric
design and 190 degree orbital movement. e
machine offers physicians 3-D technology for
use in orthopedic, trauma and spine surgery
related procedures. It is one of six machines
that Siemens manufactures, and the only one
with 3-D technology.
Ziehm NaviPort, Ziehm Imaging (Orlando).
e Ziehm NaviPort is an interface for the com-
pany's flagship C-arm device, the Ziehm Vision
RFD 3D. e NaviPort interface uses high-qual-
ity image data and integrates it into the C-arm
machine to create a crisper picture. e Navi-
Port interface obtains a quality that suits it for
orthopedic, trauma and spinal procedures.
Ziehm Vision RFD 3D, Ziehm Imaging. e
flagship product for Ziehm, the Vision RFD
3D is the only 3-D C-arm with flat-panel tech-
nology. e device combines both 2-D and
3-D functionality to maximize ease-of-use.
e RFD comes in a non-3-D version and a
hybrid edition. e device is one of Ziehm's
eight C-arm machines.
Brainlab Fluoro 3D C-Arm Registration,
Brainlab (Westchester, Ill.). Brainlab's Fluoro
3-D registration is an interface which allows
for intraoperative integration of 3-D C-arms
for both spine and trauma procedures. e
interface allows for real-time navigation of in-
traoperative datasets. e interface is compat-
ible with common 3-D C-arms like the Ziehm
Vision RFD 3D.
G-Arm Gxi series, Whale Imaging (Waltham,
Mass.). Whale Technologies' G-Arm gXi tech-
nology allows for 270 degrees of freedom to
view images from several different positions.
e first edition the gXi 1 uses Whale's biplanar
layout, allowing images to be viewed on a bi-
planar view and no longer requiring surgeons
to shi between AP and lateral views. e gXi
2 improved on the gXi 1 by adding tracking
wheels for mobility and a dual laser aiming
system.
StealthStation, Medtronic (Dublin, Ireland) .
Medtronic's StealthStation O-arm allows sur-
geons to visualize the anatomy of a patient's
spine while in surgery. It also allows for the
tracking of instruments in relation to anat-
omy. When coupled with the StealthStation
navigation soware, the technologies work
together to improve workflow, while enhanc-
ing outcomes. n
