Bone screw fixation sleeve

Bone screw fixation sleeves are implantable, tube-shaped devices designed to stabilize loose, broken, or backing-out screws in orthopedic or spinal surgeries. They create a mechanical wedge when tightened, reinforcing the screw’s grip in bone and preventing further displacement or failure.

These sleeves are typically made from non-bioabsorbable polymers and sized intraoperatively to fit the specific surgical site. They are often supplied as disposable devices, sometimes paired with complementary tools or screws for immediate use in the operating room.
