In
comparison to traditional cylindrical interbody devices, the LT-CAGE® Lumbar Tapered Fusion Device restores lordosis and sagittal balance with significantly less
reaming of the vertebral endplates. And Medtronic Sofamor Danek's Tapered
Laparoscopic Instruments are designed to easily and reproducibly place
the LT-CAGE® Device.
Features and Benefits
The LT-CAGE® Device offers the following features
and benefits:
- Provides anatomic restoration of lordosis
and sagittal balance with maximum vertebral endplate preservation -
requires 50% less endplate reaming than cylindrical constructs.
- Incorporates large openings to maximize area for bony ingrowth.
- Incorporates truncated (flat) sides, which require less dissection,
retraction, and exposure.
- consistent, reproducible placement when implanted utilizing Medtronic
Sofamor Danek's instruments.
Indications
The LT-CAGE® Lumbar Tapered Fusion Device is indicated for spinal fusion
procedures in skeletally mature patients with degenerative
disc disease (DDD) at one level from L2-S1, and may also have up to
Grade 1 spondylolisthesis
or retrolisthesis at the involved level. The LT-CAGE® Device is to be used
with autogenous bone graft and implanted by way of a laparoscopic or open
anterior approach. Patients receiving the LT-CAGE®
Device should have had at least six months of nonoperative treatment prior
to treatment with the LT-CAGE® Device. In addition, the LT-CAGE® Device should not be implanted in patients with an active
infection at the operative site or with an allergy to titanium or titanium
alloy.
Laparoscopic Surgery
As indicated, the LT-CAGE® Device is to be implanted
utilizing a laparoscopic or open anterior approach. Because of the special
instrumentation utilized to perform laparoscopic spinal surgery, such as
Medtronic Sofamor Danek's Tapered Laparoscopic Instruments, this approach
only requires a small incision (approximately 10mm).
For the patient, laparoscopic surgery may offer the following benefits:
- Less tissue damage and muscle loss;
- A significantly smaller incision than what is required for a traditional
open approach, which, in turn, presents less risk of morbidity and improved
cosmetic results; and
- Reduced hospital stay and recuperation time. Patients undergoing laparoscopic
surgery are hospitalized for just under two days versus the up to six-day
stay required for patients undergoing open surgery.
Medtronic Sofamor Danek's Tapered Laparoscopic Instruments - one of the
latest advancements in minimally
invasive surgery - are designed to easily and reproducibly place the
LT-CAGE® Device. For the surgeon, these instruments
offer the following features and benefits:
- Integrated seal system to prevent loss of insufflation.
- Color-coded instruments and cases that clearly identify the size-specific
instruments for each size of construct (14mm, 16mm, and 18mm).
- Finned distraction tips that prevent migration of the distractor during
insertion.
- Sequential distraction for optimal disc space distraction and height
restoration prior to endplate preparation.
- Centering devices for bi-lateral construct placement utilizing a trephining
method (annulotomy).
- Easy-to-use adjustable depth stops that allow for accurate, controlled
passage of instruments.
- Integrated system design that facilitates stable, accurate placement
of the construct and facilitates a consistent, reproducible operation.
 Important Safety Information
It is important that you discuss the potential risks, complications, and benefits of the LT-CAGE® with your doctor prior to receiving treatment, and that you rely on your physician's judgment. Only your doctor can determine whether you are a suitable candidate for this treatment.
