The Sternum Locking Plate is a highly specialized orthopedic implant engineered for the stable internal fixation of the sternum, or breastbone. Unlike long bones, the sternum is a flat, superficial bone that is constantly in motion due to respiration. Traditional fixation methods can fail under these cyclical forces. This plate is designed with an anatomically low-profile and is secured with locking screws to provide rigid, fixed-angle stability. This allows the plate to act as an internal splint, protecting the sternum from the stress of breathing, coughing, and other chest wall movements. The system is an ideal solution for a variety of conditions, including traumatic sternal fractures, sternal non-unions, and as a robust alternative for sternotomy closure after cardiac surgery, promoting rapid healing and a significant reduction in patient pain and discomfort.
Sternum Locking Plate
TOOLMED
Product Description
The plate is designed to be extremely thin and anatomically contoured to fit the superficial nature of the sternum, minimizing soft tissue irritation and hardware prominence.
The locking screw-to-plate interface creates a rigid, fixed-angle construct that provides superior stability, which is essential for resisting the cyclical forces of respiration and coughing.
The locking technology prevents screws from loosening or pulling out, which is a significant advantage in the thin and cancellous bone of the sternum where traditional screws may not hold.
The plate features multiple holes to allow for multi-point fixation, providing a powerful scaffold for stabilizing comminuted sternal fractures.
Crafted from a high-quality titanium alloy, the implant offers exceptional strength and biocompatibility for reliable, long-term fixation.
The Sternum Locking Plate is primarily indicated for the stable fixation of sternal fractures, including comminuted or unstable fractures that cannot be managed with conservative treatment.
It is an ideal solution for the treatment of sternal non-unions (failure of the bone to heal), providing the necessary stability for corrective procedures.
The implant is also used for sternotomy closure after open-heart surgery, offering a more robust and stable alternative to traditional wiring techniques, particularly in high-risk patients.

The Sternum Locking Plate is a specialized orthopedic implant designed for the unique challenges of sternal fixation. The sternum is constantly moving with every breath, and its bone quality can be poor, making traditional fixation methods, like wires, prone to failure. This plate uses a locking technology where the screw head locks into the plate, creating a fixed-angle construct. This makes the plate and screws act as a single, rigid unit that does not rely on compression against the thin bone. This superior stability is crucial for withstanding the high, cyclical forces of respiration and for promoting a high rate of healing in this anatomically challenging area.
The primary application of the Sternum Locking Plate is in the treatment of sternal fractures, particularly those that are displaced, comminuted, or unstable. These plates are also used to treat sternal non-unions, which can cause significant pain and disability. A very important application is in sternotomy closure after cardiothoracic surgery. In patients who are at high risk for sternal wound complications, such as those with osteoporosis, diabetes, or obesity, a locking plate provides a more robust and stable closure than traditional wires, reducing the risk of sternal dehiscence (separation) and infection.
The Sternum Locking Plate offers several key advantages. The fixed-angle stability provides a powerful "splint" that protects the sternum from the constant motion of breathing and coughing. This rigid fixation significantly reduces pain, allowing patients to breathe more easily and mobilize earlier. It also reduces the risk of non-union and infection. The low-profile, anatomical design minimizes the chance of soft tissue irritation, which is a common problem with hardware in this superficial location. Overall, this advanced system leads to faster healing and better patient outcomes with reduced complications.
The biomechanics of the Sternum Locking Plate are centered on its ability to provide a rigid, load-bearing construct that can withstand the complex forces on the sternum. The sternum is subjected to both tension and compression during the respiratory cycle. The fixed-angle locking screw system ensures that the plate and screws act as a single, stable unit, effectively neutralizing these forces and preventing micromotion at the fracture site. This is a significant advantage over traditional cerclage wires, which can fail or cut through the bone. The rigid fixation provided by the locking plate promotes direct bone healing, which is essential for a successful outcome.
The implantation of the Sternum Locking Plate is typically performed via an anterior approach. After the fracture is reduced, the surgeon positions the contoured plate on the sternum. Using a dedicated drill guide, the surgeon can then precisely place the locking screws. The locking screws are then threaded into the plate, creating the rigid fixed-angle construct. The procedure is designed to be highly secure and reliable, ensuring that the sternum is stabilized in the correct anatomical alignment for proper healing and function.
Following a successful Sternum Locking Plate fixation, a structured postoperative care plan is initiated. Due to the high stability and strength of the implant, patients often experience a significant reduction in pain and are able to breathe and mobilize more easily. They are generally encouraged to begin gentle activities and avoid heavy lifting. Regular clinical and radiographic follow-up appointments are essential to monitor fracture healing and ensure the implant remains stable throughout the recovery process.
The Sternum Locking Plate is a highly effective and reliable solution for the treatment of sternal injuries. Its innovative design, which combines a low-profile anatomical shape with advanced locking technology, provides surgeons with a powerful tool for achieving stable, customized fixation. By promoting high stability, anatomical reconstruction, and reducing pain, the Sternum Locking Plate leads to excellent clinical outcomes, a faster recovery, and a restored quality of life for the patient.
A sternum locking plate is used to provide stable fixation for fractures of the breastbone, especially those that are unstable. It is also a preferred method for closing the sternum after a sternotomy (e.g., for heart surgery), particularly in high-risk patients where traditional wiring may not be sufficient.
The sternum is constantly moving with breathing and coughing. A locking plate provides a rigid, fixed-angle construct that is independent of bone quality. This prevents micromotion at the fracture site, which reduces pain and promotes healing, unlike traditional wires that can fail under these cyclical forces.
This plate is much thinner and has a more unique anatomical contour than plates designed for long bones. It is specifically designed to be extremely low-profile to minimize irritation in this superficial location. The screws are also very short to avoid penetrating the mediastinum.
The plate is designed to be a permanent implant. However, it can be removed once the bone has fully healed if the patient experiences pain or irritation from the hardware, although this is less common due to its low-profile design.
With stable fixation from the locking plate, patients often experience less pain and are able to begin rehabilitation and return to daily activities much sooner. Full bone healing typically takes 3-6 months, with a complete return to normal activities and full function taking a few months of rehabilitation.
