TSRH-3D

Once the decision has been made for a patient to undergo surgery, the surgeon will carefully select the type of procedure to do, and will decide if spinal instrumentation will be needed. One of the newest and most popular spinal instrumentation systems used by surgeons is TSRH-3D.

The “break-through” associated with TSRH-3D is its uniquely designed pedicle screw. Pedicle screws are implants used in the thoracic and lumbar spine to help surgeons stabilize the spine. The TSRH-3D pedicle screw has a remarkable “headless” design. It has proven to be one of the smallest yet strongest spinal implants available today. The screws were designed using the most advanced engineering technology and finite-element-analysis (FEA). FEA has shown the remarkable structural integrity and strength of the screws.

Surgeons like the “headless” pedicle screws for several reasons, including:

1. Design: The headless screw design makes it easier for the surgeon to implant the pedicle screw while avoiding the facet joint.
2. Flexibility: Three-dimensional (3-D) means implant flexibility.
3. Versatility: Adjusts for anatomical differences in patients.
4. Unlike older screw designs, TSRH-3D allows the surgeon to manipulate the lumbar spine to help restore normal contour. When the surgeon is satisfied with re-positioning of the lumbar spine, the components are locked into place.
5. TSRH-3D pedicle screws can be implanted at each spinal level regardless of the extent of the deformity.
6. Spine fixation using TSRH-3D reduces the amount of motion between two vertebral segments. A stable construct facilitates fusion.
7. Operating time and post-operative pain is reduced.

More than 13,000 patients have been successfully treated using TSRH-3D spinal instrumentation. The implant’s ease-of-use has been recognized by many surgeons. The advantages of this implant equates to less operating time, fewer complications and faster recoveries for patients.

The TSRH-3D Spinal Instrumentation has been described by surgeons across the country, as the easiest way to “instrument” the spine because of the often-dramatic in-surgery time savings. For the patient, ease-of-use to a surgeon means a shorter operation, fewer complications and less recovery time.

Another technological advancement of the TSRH-3D instrumentation is its strength. Medtronic Sofamor Danek is committed to the strength and safety of all of its implants and products.

Because every patient is different it is important for a screw system to adjust for anatomical differences.

In 1992 the TSRH Variable Angle Screw was the first implant that eliminated the concerns of what angle the screw connected to the rod. This was an enormous benefit to both surgeon and patient.

In 1998 the TSRH-3D instrumentation repeated history when it became the first spinal implant to eliminate concerns for what height the screw is connected to the rod. This is where the addition “3D” came from, meaning the 3rd dimension of implant flexibility.

TSRH-3D for 2001
Now the TSRH-3D design has been refined with the use of a technology known as finite-element-analysis. The new design has been able to maintain all of its characteristics, increase its strength, while significantly reducing its size. So, in addition to being the easiest and among the strongest, it is now one of the smallest.
