The Distal Femoral Locking Plate is a specialized orthopedic implant engineered for the stable internal fixation of fractures in the distal end of the femur, the area just above the knee joint. These fractures are often complex and can involve the joint surface, requiring precise anatomical reduction and a robust fixation to withstand the high loads of weight-bearing. The plate is anatomically pre-contoured to fit the lateral aspect of the distal femur, with a broad head featuring multiple locking screw holes to capture and stabilize articular fragments. The locking screw technology provides a fixed-angle construct that acts as a stable "bridge" over the fracture site, protecting the fragments and allowing for early, controlled knee motion. This system is crucial for restoring joint function and preventing post-traumatic arthritis.

Product Description
The plate is specifically designed to match the complex anatomical shape of the distal femur, providing an optimal fit that simplifies surgical placement and reduces the need for intraoperative bending.
The broad head of the plate features multiple locking screw holes, strategically placed to capture and secure small bone fragments of the femoral condyles, ensuring precise articular reduction and stability.
The locking screw-to-plate interface creates a fixed-angle construct that provides superior stability and is particularly beneficial in comminuted intra-articular fractures or in osteoporotic bone.
The plate’s low-profile design minimizes irritation to the surrounding soft tissues and muscles, reducing patient discomfort and the potential for hardware prominence.
Crafted from a high-quality titanium alloy, the implant offers exceptional strength, biocompatibility, and fatigue resistance to withstand the high loads of the knee joint.
The Distal Femoral Locking Plate is primarily indicated for the stable fixation of a wide range of fractures of the distal femur, including supracondylar, unicondylar, and intercondylar fractures.
The plate is an excellent solution for periprosthetic fractures (fractures around a knee replacement) where a stable, rigid fixation is required to bridge the fracture.
The implant is also suitable for the treatment of non-unions and malunions (improperly healed fractures) of the distal femur, providing the necessary stability for corrective procedures.

The Distal Femoral Locking Plate is a specialized orthopedic implant used to treat fractures of the femur near the knee joint. This region is critical for weight-bearing and knee function, making stable fixation paramount. The plate is designed with an anatomical contour to match the lateral side of the distal femur and uses locking screw technology. This combination is ideal because it provides a fixed-angle construct that acts as a strong, internal splint. This "bridge" protects the fracture fragments from high loads, allowing the bone to heal in proper alignment, which is crucial for restoring the smooth articular surface of the knee joint.
The primary application of the Distal Femoral Locking Plate is for the stable internal fixation of a wide range of fractures of the distal femur. These can include supracondylar fractures (above the condyles), which are often comminuted, or intercondylar fractures that split the articular surface. The plate's design allows for the precise reduction and fixation of these fragments, which is critical for restoring knee kinematics and preventing post-traumatic arthritis. It is also an excellent option for non-unions or malunions, providing the necessary stability for a second chance at healing and proper alignment.
The Distal Femoral Locking Plate offers several key advantages for treating complex fractures near the knee. The anatomically pre-contoured shape simplifies the surgical procedure and ensures an optimal fit. The fixed-angle stability provided by the locking screws is independent of the bone quality, making it a reliable solution even in comminuted or osteoporotic bone. This robust fixation allows for early, controlled knee range of motion and weight-bearing, which are essential for preventing joint stiffness and stimulating bone healing. The stable construct also reduces the risk of loss of reduction, which can lead to poor outcomes and the need for re-operation.
The biomechanics of the Distal Femoral Locking Plate are based on creating a rigid, load-bearing construct that protects the fracture fragments. The plate, when secured with locking screws, acts as an internal fixator, forming a "bridge" over the fracture gap. This "bridge" is highly resistant to axial, bending, and torsional forces, which the distal femur is subjected to. The multiple locking screw holes in the plate head provide a strong "raft" of support for the articular fragments, preventing them from collapsing under load. This superior biomechanical stability ensures that the fracture heals in the correct anatomical position, restoring the smooth articular surface.
The implantation of the Distal Femoral Locking Plate is typically performed via a standard lateral approach to the distal femur. After the fracture is reduced, with careful attention paid to the articular surface, the pre-contoured plate is positioned on the bone. The surgeon uses a targeting guide to precisely place the locking screws into the femoral condyles. The screws are then threaded into the plate, creating the fixed-angle construct. The procedure is designed to be highly secure and reliable, ensuring that the bone is stabilized in the correct anatomical alignment for proper knee function.
Following a successful Distal Femoral Locking Plate fixation, a structured postoperative care plan is initiated. Due to the high stability and strength of the implant, patients are often able to begin early, controlled knee range of motion exercises and partial weight-bearing as prescribed by the surgeon. Physical therapy is a crucial component of recovery, focusing on restoring joint function and muscle strength. Regular clinical and radiographic follow-up appointments are essential to monitor fracture healing and ensure the implant remains stable throughout the recovery process.
The Distal Femoral Locking Plate is an indispensable tool in orthopedic trauma surgery. Its innovative design, which combines an anatomical shape and advanced locking technology, provides surgeons with a powerful solution for even the most challenging distal femoral fractures. By promoting high stability, anatomical reconstruction, and facilitating early patient mobility, the Distal Femoral Locking Plate leads to excellent clinical outcomes, a faster recovery, and a restored quality of life for the patient.
A locking plate provides fixed-angle stability that is independent of bone quality. This is crucial for fractures involving the knee joint, which are often comminuted or occur in osteoporotic bone, where traditional screws might not hold, risking collapse of the joint surface.
The plate itself does not restore the joint surface. However, its anatomical shape and the multiple locking screws in the head allow the surgeon to precisely reduce and secure the articular fragments, creating a stable buttress that supports the joint surface and allows it to heal properly.
This plate is specifically designed for the distal end of the femur. It has a broad, anatomically contoured head with multiple screw holes to capture articular fragments. A standard femoral plate is designed for the shaft and has a straight or curved body for mid-diaphyseal fractures.
With stable fixation from the locking plate, patients can often begin early range of motion exercises for the knee. Full healing typically takes 3-6 months, and physical therapy is essential to regain strength and full function.
The plate is designed to be a permanent implant. However, it can be removed once the fracture has fully healed if the patient experiences pain or irritation from the hardware.
