The set is also designed with OR staff in bind with a comparatively
more compact instrumentation set when compared with the standard.
Addressing the acetabulum in revision surgery can also be quite
challenging for which DePuy is announcing their GRIPTION TF system, a
bony augment system designed for use with their PINNACLE acetabular cup
system. This system is designed for cases where there are areas of
missing bone in the acetabulum. The implant is made from a porous
titanium designed to have a modulus of elasticity similar to bone. It
utilizes locking screw technology for more rigid fixation along with a
divergent screw configuration.
We have covered DePuy's TRUMATCH
personalized knee replacement technology in the past. Using CT scans
from the knees of patients DePuy will actually create customized cutting
blocks to be used during their surgery, which they claim improves
outcomes and decreases operating room time. At AAOS DePuy announced the
next generation of this line, TRUMATCH Personalized Solutions 2.5i,
which provides enhanced capabilities and efficiency.
The last two product announcements, GLOBAL UNITE and GLOBAL STEPTECH, address shoulder replacement. GLOBAL UNITE is a system designed for
fractures of the proximal humerus, with a unique feature being that it
can later be converted to a reverse shoulder arthroplasty down the road.
The GLOBAL STEPTECH system is designed for shoulders which have
excessive bone loss in the posterior aspect of the glenoid (socket). It
uses a proprietary step design which corrects the abnormal anatomy and
counteracts posterior loading.
Here's more about the newly launched DePuy products from the press release:
Approved for use with the SIGMA Rotating Platform Knee System and LCS COMPLETE Mobile Bearing Knee System, the new AOX Polyethylene delivers
an advanced blend of polyethylene resin and a unique antioxidant,
COVERNOX, to create a new polyethylene material that is highly
efficient in trapping free radicals and scavenging oxygen. By
eliminating the annealing or remelting process, AOX Polyethylene
delivers oxidative stability and optimum wear resistance without
compromising the mechanical properties or strength of the polyethylene. By introducing COVERNOX Antioxidant into the base resin before the
polyethylene is consolidated, the process enables the antioxidant to be
uniformly dispersed and remain blended, eliminating the risk of outward
Hip Revision Solutions
The RECLAIM Modular Revision Hip System is engineered to deliver a high
level of implant strength. This system has been studied extensively
through analytic techniques and rigorous laboratory testing and has
demonstrated promising capabilities, particularly with respect to
construct fatigue strength and torsional stability. The modular design
of the RECLAIM Revision Hip System features novel instrument technology
that may improve intraoperative handling, flexibility, and efficiency.
The modularity of the system offers surgeons numerous options to treat a
patient's unique pathology while simplifying the instrumentation
required in surgery.
DePuy's GRIPTION TF Acetabular Augment System addresses bone defects
in moderate to complex acetabular revision surgery using a highly porous
structure made from commercially pure titanium; a strong,
corrosion-resistant metal that has high surface roughness and a similar
elasticity to bone. The GRIPTION TF System offers a wide range of
options and configurations for the patient at the time of surgery and is
designed to work in conjunction with the full range of PINNACLE
Acetabular Cup options.
Procedural Efficiency in Knee Replacement
TRUMATCH Personalized Solutions 2.5i provides enhanced capabilities that
aid implant positioning and procedural efficiency. TRUMATCH, which
reduces procedure time by up to 35 minutes, is the first system to
utilize CT scans and computer software to guide the development and
production of femoral and tibial cutting blocks that are individually
prepared to match the actual bone surfaces of each patient. The use of
CT scans, rather than MRIs, results in improved bone imaging, less
scanning time, and lower costs.
Advanced Shoulder Solutions
DePuy is launching two new shoulder solutions. The GLOBAL UNITE Platform
System, which treats fractures of the proximal humerus, helps improve
tuberosity healing and is the only system that can later be easily
converted to a reverse shoulder arthroplasty for treatment of arthritis
with a torn rotator cuff. The GLOBAL STEPTECH APG System has been
designed to correct excessive retroversion caused by posterior glenoid
bone loss, closely recreate the original glenohumeral joint line, and
minimize the removal of healthy bone. The prosthesis incorporates a
proprietary step design with an anterior backside surface that is
spherical and a posterior backside surface that is conical. This unique
dual surface design effectively counteracts posterior loading.
