Product Description
The plate head is pre-shaped to fit the medial aspect of the proximal tibia. This reduces surgical time and ensures the screws are directed away from the joint surface and the osteotomy line.
The threaded locking interface between the screw and plate provides a rigid construct that prevents "toggling" or loss of leveling, even in the high-stress environment of a giant breed dog's stifle.
Offers a modulus of elasticity closer to bone than stainless steel, reducing stress shielding and the risk of implant-associated infection, while being significantly lighter for the patient.
The distal shaft holes are designed to allow for both dynamic compression (to close the osteotomy gap) and locking fixation (to provide final rigid stability).
The primary indication for this system. It is used to stabilize the stifle joint after a TPLO osteotomy by leveling the tibial plateau to eliminate cranial tibial thrust.
Though specialized for the tibia, the TPLO plate's head configuration is sometimes indicated for complex distal femoral or proximal tibial corrective osteotomies to manage patellar luxation.
Specifically indicated for active, sporting, and working dogs where traditional extracapsular repairs may fail due to the high mechanical forces applied during sprinting and jumping.
Indicated for proximal tibial plateau fractures in large breed dogs where an anatomical "A-Type" fit is required to support the articular surface while providing rigid shaft fixation.

The Veterinary TPLO Locking Plate (A Type Head Lock) is a specialized orthopedic implant used in Tibial Plateau Leveling Osteotomy. The "A Type" refers to the specific anatomical curvature of the plate head which is designed to sit on the medial surface of the proximal tibia, avoiding the joint capsule and tibial tuberosity. The "Head Lock" technology means that the screw heads thread into the plate holes, creating a "fixed-angle" construct. This is vital in TPLO surgery because the plate must support the entire weight of the dog as it walks on a bone that has been cut into two pieces. It is manufactured from medical Titanium to ensure long-term biocompatibility and the strength required for large, active dogs.
This system is exclusively applied in veterinary surgery to treat Cranial Cruciate Ligament (CCL) disease in dogs. Unlike human ACL repairs which use a graft, the TPLO procedure uses these plates to stabilize the bone after the top of the tibia is rotated to change the biomechanics of the knee. The A-Type plate is applied to the medial side of the tibia. Its specific hole arrangement allows for three or four screws to be placed in the proximal "rotated" fragment, ensuring it does not shift during the healing process. It is the gold standard application for medium to giant breed dogs who require a permanent, high-strength solution for knee stability.
The primary advantage of the TOOLMED TPLO system is the reduction in "screw-out" complications. Because the screws lock into the plate, they cannot loosen or back out due to the repetitive vibration of a dog walking. The Titanium construction is a significant advantage over stainless steel; it is more "biological," causing less tissue reaction and having better infection resistance—a critical factor in TPLO where implant-associated infections can be devastating. Furthermore, the pre-contoured A-Type design fits the bone so well that surgeons spend less time bending the plate, which reduces the animal's time under anesthesia and maintains the strength of the Titanium alloy.
Biomechanically, the TPLO plate must act as a tension-band construct. When the dog bears weight, the plate resists the massive forces that want to push the tibial plateau backward. The Head Lock mechanism ensures that the screws and plate act as a single unit, providing a fixed-angle stability that is much stronger than traditional non-locking plates. The scalloped "Biological" underside of the plate reduces the contact area with the bone, which ensures that the blood supply to the osteotomy site is not compromised, leading to faster "bony union" and a quicker return to full activity for the pet.
The surgical technique begins with the osteotomy using a radial saw. Once the tibial plateau is rotated to the desired angle, the A-Type TPLO plate is positioned. The surgeon typically uses a non-locking "compression" screw in the distal shaft first to pull the osteotomy gap tight. Then, the proximal "Head Lock" screws are inserted through a threaded drill guide to ensure perfect axial alignment. Once the proximal fragment is locked, the remaining distal screws are inserted. The anatomical shape of the A-Type head ensures that the screws avoid the joint space and the patellar ligament attachment point (tibial tuberosity).
Postoperative care for the pet includes strictly controlled leash walking for 8–12 weeks. For the instrument set, care involves preserving the precision of the locking drivers and drill guides. Following surgery, the TPLO-specific drill bits and threaded guides must be cleaned of bone debris using an ultrasonic cleaner. The Titanium plates are single-use and should never be re-bent if the surgery is revised. The instrument tray should be sterilized at 134°C. Proper lubrication of the moving parts in the drill guides is essential to prevent the "cold-welding" of the locking threads during future use.
The TOOLMED Veterinary TPLO Locking Plate (A Type Head Lock) offers the perfect balance of anatomical fit and mechanical rigidity. By utilizing medical Titanium and advanced locking technology, it provides veterinary surgeons with a reliable system for achieving excellent long-term results in canine knee stabilization.
The A-Type features a more traditional anatomical head shape for the medial tibia, while other types may offer different hole configurations or lower-profile necks for specific breeds or surgical preferences.
Yes. Our 3.5mm Broad TPLO plates are made from Ti-6Al-4V, which has a higher fatigue strength than 316L stainless steel, specifically designed to handle the weight of giant breed dogs.
While similar, CBLO (CORA-Based Leveling Osteotomy) often requires different screw angulations. We recommend using our dedicated CBLO system for those specific cases.
Yes, because the plate is anatomically contoured to the medial tibia, you must specify a Left or Right plate depending on which leg is being operated on.
The A-Type is pre-contoured for the "average" canine tibia. In most cases, little to no bending is required, but small adjustments can be made with TPLO bending irons if necessary.
