The TOOLMED Veterinary TPLO (Tibial Plateau Leveling Osteotomy) B-Type Plate is a sophisticated Titanium implant designed for the stabilization of the proximal tibia following CCL rupture treatment. The "B-Type" configuration offers a refined anatomical head shape, providing optimized screw trajectories that ensure maximum purchase in the proximal rotated fragment while safely avoiding the articular surface. This system features the "Rod Lock" technology, which utilizes a specialized tapered thread interface between the screw head and the plate's nodal pearls to create a rigid, fixed-angle construct. Manufactured from premium Ti-6Al-4V Titanium alloy, the plate combines exceptional fatigue life with superior biocompatibility, essential for the high-impact loading of active dogs. The "Biological" under-surface design minimizes bone contact, preserving the periosteal blood supply to facilitate rapid osteotomy healing. Available in a full range of sizes, the B-Type Rod Lock system offers veterinary surgeons a reliable, high-performance alternative for complex stifle reconstructions.

Product Description
The B-Type head is engineered with a specific curvature to maximize the distance between the screws and the osteotomy cut, reducing the risk of fracture in the proximal tibial fragment.
The Rod Lock mechanism ensures a cold-weld-like seal between the screw and plate, preventing "windshield-wiper" loosening and maintaining the leveled tibial plateau under full weight-bearing.
The scalloped underside reduces the implant's footprint on the bone, ensuring that 60% of the periosteum remains untouched to promote faster biological "bony union."
Utilizing medical-grade Titanium Alloy (Ti-6Al-4V), the system is significantly more resistant to cyclic loading than stainless steel, making it ideal for working breeds and hyper-active dogs.
The primary indication for this system is the stabilization of the canine stifle joint. The B-Type design is particularly effective for dogs with specific proximal tibial anatomy that requires a more posterior screw trajectory.
Can be adapted for use in large-breed pelvic reconstructions or corrective femoral osteotomies where a high-strength, pre-contoured Titanium head is required for metaphyseal stabilization.
Indicated for high-performance sporting dogs where extreme rotational and axial stability is required to prevent "thrust" during post-surgical recovery and future activity.
Specifically indicated for revision cases where the "B-Type" hole configuration allows for screw placement in healthy bone away from previous implant tracks or bone voids.

The Veterinary TPLO B-Type Rod Lock is a premium Titanium internal fixation system designed for Tibial Plateau Leveling Osteotomy. The "B-Type" refers to its specific anatomical plate-head morphology, which provides an alternative screw arrangement to the A-Type, often allowing for more versatile screw placement in the proximal tibial segment. The "Rod Lock" technology utilizes a high-precision threaded interface where the screw head locks into the plate's nodal pearls. This creates a monolithic, fixed-angle construct that essentially functions as an internal fixator, carrying the load of the dog's weight while the osteotomy heals. Its Titanium construction ensures the highest levels of biocompatibility and mechanical strength required for modern canine orthopedics.
This system is primarily applied to treat Cranial Cruciate Ligament (CCL) rupture in dogs, a common injury that leads to hind limb lameness. The B-Type plate is specifically used when the veterinarian requires optimized screw trajectories to secure the rotated tibial plateau. Its application is most common in medium to giant breed dogs, where the mechanical forces on the stifle are immense. By leveling the plateau and fixing it with the B-Type plate, the cranial tibial thrust is eliminated, allowing the dog to walk and run without the need for a ligament graft. It is also used in complex proximal tibial fractures that mimic the TPLO anatomy.
The primary advantage of the B-Type Rod Lock is its biomechanical reliability. Traditional plates can suffer from "screw back-out," but the Rod Lock mechanism makes this virtually impossible. Furthermore, the Titanium alloy (Ti-6Al-4V) is superior to stainless steel for active pets; it is lighter, has better fatigue life, and produces significantly less artifact on postoperative imaging. The anatomical pre-contouring of the B-Type head matches the medial proximal tibia so closely that intraoperative bending is minimized, which preserves the structural integrity of the Titanium and reduces the total time the animal is under anesthesia.
Biomechanically, the system operates as a tension-band internal fixator. As the animal bears weight, the plate resists the massive sheer forces across the osteotomy site. The "Biological" underside design is a critical biomechanical feature; by reducing plate-to-bone contact, it preserves the blood supply (periosteum), which is the most important factor in rapid bone healing and preventing infection. The fixed-angle nature of the Rod Lock screws ensures that the leveling of the tibial plateau achieved during surgery is maintained permanently, preventing the "collapse" of the construct during the critical early recovery phase.
The technique begins with a standard medial approach to the proximal tibia and the performance of the radial osteotomy. Once the tibial plateau has been rotated to the pre-calculated angle, the B-Type plate is positioned. The surgeon typically places a compression screw in the distal shaft to close the osteotomy gap, followed by the insertion of the proximal locking screws through a threaded drill guide. The Rod Lock mechanism requires that the screw be fully seated to ensure the tapered threads engage. The anatomical curvature of the B-Type head naturally guides the screws away from the joint surface and the tibial tuberosity, ensuring a safe and stable repair.
Postoperative care for the pet involves strict rest and leash walking for approximately 8–12 weeks. For the surgical team, maintenance of the Rod Lock instrument set is essential. After surgery, the threaded drill guides and screwdriver tips must be cleaned using an ultrasonic bath to remove all microscopic biological debris from the locking interfaces. The Titanium plates are single-use; once they have been implanted or bent, they must never be re-used. The instrument tray should be sterilized using a standard steam autoclave at 134°C. Proper inspection of the screwdriver tips for wear is critical to prevent screw head damage in future procedures.
The TOOLMED Veterinary TPLO B-Type Rod Lock System represents the pinnacle of stifle stabilization technology. By combining a refined anatomical fit with the rigid security of Titanium Rod Lock technology, it provides veterinary surgeons with a reliable and biologically friendly solution for challenging canine knee repairs.
Surgeons often choose the B-Type when the specific anatomy of the patient's tibia requires a different screw trajectory to avoid the osteotomy line or to gain better purchase in the proximal fragment.
Yes, the set includes specialized self-retaining drivers that match the tapered locking head of the Rod Lock screws to ensure they are fully seated and locked into the plate.
Our Titanium TPLO plates are typically color-anodized (e.g., Blue for 3.5mm, Gold for 2.7mm) to help your surgical team identify the correct sizes and orientations quickly during surgery.
No, the B-Type is anatomically pre-contoured for either the Left or Right medial tibia. You must select the specific orientation for your patient's surgery.
Titanium alloy has a higher strength-to-weight ratio and better fatigue resistance than stainless steel, meaning it is less likely to break under the repetitive stress of a 50kg dog walking.
