Product Description
The screw head locks directly into the plate node, preventing any toggling or movement at the screw-plate interface, which is critical for maintaining fracture alignment under early weight-bearing.
The plate features a "pearl-and-rod" geometry that can be easily shaped to fit the unique anatomy of different animal species without compromising the integrity of the locking holes.
The scalloped design ensures point-contact with the bone, significantly reducing the risk of periosteal necrosis and promoting faster biological healing compared to traditional compression plates.
Titanium’s high fatigue strength and lower modulus of elasticity reduce "stress shielding" and minimize the implant’s profile under thin-skinned areas of the animal's limbs.
Indicated for complex scapular and proximal humeral fractures where the plate must be contoured around the joint. The head-lock mechanism provides stability in the thin bone of the scapula.
The primary choice for Triple Pelvic Osteotomy (TPO) or pelvic symphysis repairs. The fixed-angle stability is essential for maintaining the corrected pelvic orientation in active dogs.
Applied in distal femoral physeal fractures (Salter-Harris types). The locking screws provide excellent purchase in the soft cancellous bone of the epiphysis.
Specifically indicated for carpal or tarsal arthrodesis in small breeds. The reconstruction design allows the plate to bridge the joint while the locking screws prevent construct collapse during the fusion process.

The ALPS Head Lock Type is an advanced Titanium internal fixation system designed for veterinary orthopedic surgery. The "Head Lock" designation refers to the specific mechanism where the screw head threads directly into the plate node (the "pearl"). This creates a monolithic, fixed-angle construct that does not rely on bone-to-plate friction for stability. The plate is designed with a reconstruction profile—a series of nodes connected by narrower rods—allowing it to be bent and twisted to fit the complex, non-linear bone shapes found in small animals. It represents a shift from traditional compression plating to modern internal fixation, emphasizing biological preservation and mechanical rigidity.
In veterinary practice, this system is primarily applied to fractures where traditional plating is likely to fail, such as in highly comminuted (shattered) fractures, osteoporotic bone in older pets, or fractures very close to a joint. It is widely used for distal radius/ulna fractures in toy breeds, which are notorious for poor healing, and for mandibular reconstructions. The "bridging" application is common, where the plate spans the entire fracture zone to support the weight of the animal while the bone heals underneath, making it a critical tool for large-breed dogs who cannot be easily rested.
The key advantage is the "Head Lock" security. By locking the screw to the plate, the system prevents "windshield-wiper" loosening of screws, which is a common cause of failure in animal orthopedics. Additionally, the Titanium construction is highly resistant to the "cold welding" often seen in stainless steel locking systems, making removal (if necessary) much easier. The low-profile "pearl" design reduces the amount of metal under the skin, which is vital for distal limbs where soft tissue is scarce. Finally, the ability to contour the plate in three dimensions without specialty tools saves valuable time in the operating room.
Biomechanically, the Head Lock ALPS system acts as a "stress-sharing" internal fixator. The fixed-angle screws transform the plate into a rigid frame that protects the fracture site from bending and torsional forces. Because the plate is not pressed tightly against the bone, the blood supply (periosteum) remains intact, which is a major biomechanical advantage for faster callus formation. The system is engineered to provide a modulus of elasticity that is closer to natural bone than stainless steel, reducing the risk of bone atrophy due to stress shielding.
The surgeon begins by contouring the plate using ALPS-specific bending pliers to match the bone's anatomy. Once the fracture is reduced, the plate is positioned. A dedicated locking drill guide is screwed into the plate node to ensure perfect axial alignment. A pilot hole is drilled, and the locking screw is inserted. As the screw is fully seated, the threads on the screw head engage with the threads in the plate node, locking the two together. This process is repeated across the fracture gap. Post-insertion, the rigid construct allows for immediate, controlled load transfer through the plate rather than the fracture site.
Postoperative care for the veterinary patient involves controlled exercise and monitoring for 6–10 weeks. For the surgical facility, care involves the meticulous maintenance of the Head Lock instrumentation. The threaded drill guides and screwdriver tips must be inspected for wear, as damaged threads can compromise the locking mechanism. Instruments must be cleaned with enzymatic solutions and subjected to ultrasonic cleaning to remove bone fragments from the locking interfaces. The set is then steam-sterilized at 134°C. Titanium implants are strictly single-use; re-bending a plate multiple times can lead to metal fatigue and intraoperative failure.
The TOOLMED ALPS Reconstruction Locking Plate System (Head Lock Type) provides the ultimate combination of fixed-angle stability and anatomical flexibility. For the veterinary surgeon, it offers a reliable, biologically friendly solution for complex fracture management in pets of all sizes.
The Rod Lock type allows for more flexibility at the connecting rods for 3D shaping, while the Head Lock type emphasizes a high-strength threaded connection at the plate hole for maximum rigid stability.
Yes, we offer 1.6mm and 2.0mm "Mini" ALPS systems specifically designed for the delicate bone structures of cats and small toy dogs.
While a standard driver can be used, we highly recommend our torque-limiting handle to ensure the screw head is perfectly locked into the plate without over-tightening or stripping the threads.
The reconstruction design allows the plates to be cut to any length using heavy-duty cutters, or we provide pre-cut lengths ranging from 4 to 20 nodes.
Titanium forms a stable oxide layer that is more resistant to bacterial colonization than stainless steel, making it a better choice for open fractures or contaminated wound sites in animals.
