Proximal Lateral Tibial Locking Plate-II

What is Proximal Lateral Tibial Locking Plate？

The CZMEDITECH 3.5 mm LCP® Proximal Tibia Plate is part of the LCP Periarticular Plating System, which merges locking screw technology with conventional plating techniques. The LCP Periarticular Plating System is capable of addressing complex fractures of the distal femur with the 3.5 mm LCP Condylar Plates, complex fractures of the proximal femur with the 3.5 mm LCP Proximal Femur Plates and 3.5 mm LCP

Proximal Femur Hook Plates, and complex fractures of the proximal tibia when using the 3.5 mm LCP Proximal Tibia  Plates and 3.5 mm LCP Medial Proximal Tibia Plates.

The locking compression plate (LCP) has Combi holes in the plate shaft that combine a dynamic compression unit (DCU) hole with a locking screw hole. The Combi hole provides the flexibility of axial compression and locking capability throughout the length of the plate shaft.

Plate Features:

• Anatomically contoured to approximate the lateral aspect of the proximal tibia

• Can be tensioned to create a load-sharing construct

• Available in left and right configurations, in 316L stainless steel or commercially pure (CP) titanium

• Available with 5、7、9 or 11 Combi holes in the plate shaft

• The two round holes distal to the head accept 3.5 mm cortex screws and 3.5 mm cancellous bone screws for interfragmentary compression or to secure plate position

• An angled, threaded hole, distal to the two round holes, accepts the 3.5 mm cannulated locking screw. The hole angle allows this locking screw to converge with the central locking screw in the plate head to support a medial fragment

• Combi holes, distal to the angled locking hole, combine a DCU hole with a threaded locking hole

• Limited-contact profile

Proximal Lateral Tibial Locking Plate: An Overview of Indications, Surgical Technique, and Outcomes

Fractures of the proximal tibia can be difficult to manage, especially in cases of comminuted or osteoporotic fractures. The use of a proximal lateral tibial locking plate (PLTLP) has emerged as an effective method for treating these complex fractures. In this article, we will discuss the indications, surgical technique, and outcomes associated with the use of a PLTLP.

Indications

The PLTLP is primarily used for the treatment of fractures of the proximal tibia, including those that involve the tibial plateau, the medial and lateral condyles, and the proximal shaft. It is particularly useful for fractures that are difficult to stabilize with traditional methods, such as intramedullary nails or external fixators. The PLTLP can also be used in cases of nonunion or malunion of the proximal tibia.

Surgical Technique

The PLTLP is typically inserted through a lateral approach to the knee joint. The surgeon will make an incision over the lateral aspect of the knee, and then expose the fracture site. The fracture fragments are then reduced and temporarily fixed in place with Kirschner wires. Next, the PLTLP is contoured to fit the proximal tibia and fixed in place with locking screws. The locking screws provide stability by engaging with the bone and preventing rotational or angular motion.

Outcomes

Studies have shown that the use of a PLTLP results in high rates of union and good clinical outcomes. One study reported a union rate of 98% and a mean Knee Society Score of 82 at an average follow-up of 24 months. Another study reported a union rate of 97% and a mean Knee Society Score of 88 at an average follow-up of 48 months. However, it should be noted that individual outcomes may vary depending on the specific patient and fracture characteristics.

Potential Complications

Complications associated with the use of a PLTLP include infection, nonunion, malunion, and hardware failure. Careful patient selection and surgical technique are important for minimizing the risk of complications. The surgeon should also take care to avoid damaging the surrounding soft tissue, such as the peroneal nerve or the lateral collateral ligament.

Conclusion

The proximal lateral tibial locking plate is a useful tool in the treatment of complex fractures of the proximal tibia. It provides stability and allows for early mobilization, which can lead to better clinical outcomes. While complications are possible, careful patient selection and surgical technique can help minimize the risk. Overall, the PLTLP is a valuable addition to the orthopedic surgeon's armamentarium for the treatment of proximal tibia fractures.

FAQs

1. How does the proximal lateral tibial locking plate compare to other methods of treating proximal tibia fractures? The PLTLP has been shown to be an effective method for treating complex fractures of the proximal tibia, particularly those that are difficult to stabilize with traditional methods. However, individual outcomes may vary depending on the specific patient and fracture characteristics.

2. What are the advantages of using a proximal lateral tibial locking plate? The PLTLP provides stable fixation of the fracture fragments and allows for early mobilization, which can lead to better clinical outcomes. It is particularly useful for complex fractures that are difficult to stabilize with traditional methods.

3. What are the potential complications of using a proximal lateral tibial locking plate? Complications associated with the use of a PLTLP include infection,nonunion, malunion, and hardware failure. Careful patient selection and surgical technique can help minimize the risk of complications.

4. How long does it take for the proximal lateral tibial locking plate to heal? The time it takes for a PLTLP to heal varies depending on the individual patient and the nature of the fracture. However, studies have shown high rates of union with the use of a PLTLP.

5. Can the proximal lateral tibial locking plate be removed after the fracture has healed? Yes, the PLTLP can be removed once the fracture has healed if it is causing discomfort or other issues. However, the decision to remove the hardware should be made on a case-by-case basis and in consultation with the patient's surgeon.
