GRAVITY® Titanium Suture Anchors are designed to provide optimal stability,
while reducing the number of steps required for implantation. All anchors
feature an internal square drive and suture eyelet, allowing for pre-loaded
suture that is protected during insertion. GRAVITY® Titanium Suture Anchors
are available in 2.7, 3.5, and 5.5mm diameters. GRAVITY® Titanium Suture
Anchors may be used to address a variety of applications that span the
forefoot, midfoot, and hindfoot.

System Benefits
» High-strength Force Fiber® surgical suture maximizes construct stability
» Fully-threaded titanium anchor design increases pull-out strength
» Aggressive, self-tapping cutting flutes ease anchor insertion
» Silicone-Free Force Fiber® suture features a low-profile design, minimizing
soft-tissue irritation by reducing knot size and allowing for contiguous
placement of multiple knots*
» Suture organization helps save time and streamlines the procedure
» Pre-loaded anchor design eliminates the need for intraoperatively threading
suture through the anchor eyelet or needle, reducing the number of
procedural steps
Modular handle design allows for organized
suture & needle deployment.
Silicone-free Force Fiber® braid configuration
enhances suture strength and handling
characteristics.

GRAVITY® Titanium Suture Anchor Size Assessment
The GRAVITY® Titanium Suture Anchor System features multiple anchor
diameters and suture options. The surgeon’s final decision on anchor size and
suture should be based on the procedure’s requirement of the device, the
degree of soft-tissue tension involved, and the patient’s anatomy.

Pre-Drilling
In most cases, the design of the GRAVITY® Titanium Suture Anchor allows it
to be inserted without tapping or pre-drilling. The surgeon may choose to use
a pre-drill to ease the insertion torque required to insert the anchor. When
needed, choose the appropriate drill as indicated below.

GRAVITY® Titanium Suture Anchor 5.5mm
(P/N 86TAN255)
Anchor Positioning
Prior to insertion, position the driver tip to achieve the desired trajectory. While
maintaining slight pressure and ensuring that the anchor is free of soft-tissue,
rotate the handle clockwise to begin advancement.
Anchor Seating
Advance the anchor until the optimal depth has been reached. A driver shaft
depth marker is located 1mm above the anchor and may be used as a reference
during insertion.
| Figure 1
Suture Deployment
All anchors are loaded with ForceFiber® sutures which pass through the anchor,
up the driver shaft, and wrap inside the suture cartridge. Upon final seating of
the anchor, release the suture cartridge by pulling back on the cartridge’s driver
shaft clasp and disengaging it from the driver shaft. | Figure 1 When the suture
cartridge is fully disengaged from the handle, gently pull back on the driver
handle to release the driver tip from the suture anchor. | Figure 2
Set aside the driver handle and maintain possession of the suture cartridge.

Soft-tissue Fixation
Using a needle driver, hemostat, or forceps, remove each needle from the
cartridge and drive them through the desired soft-tissue, tensioning the tissue
as needed. Secure the soft-tissue to the bone by tying knots with the suture. It
may be helpful to use the suture cartridge to organize the needles and suture
during soft-tissue fixation.
Explant Information
The implant can be removed if needed. To re-engage the anchor, utilize the
handle and driver shaft of the appropriate size driver (see sizing chart). Insert
the driver tip into the anchor and rotate the handle counterclockwise to
remove the implant.
Postoperative Management
If the removal of the implant is required due to revision or failure of the device,
the surgeon should contact the manufacturer using the contact information
located on the back cover of this surgical technique to receive instructions for
returning the explanted device to the manufacturer for investigation.
Postoperative Care
Postoperative care is the responsibility of the medical professional.
