Variolock Locking Plate System
Variolock Variable Angle Locking Plate System by Siora Surgicals Pvt. Ltd. is an advanced locking system that is capable of addressing different fracture patterns effectively. Made of medical-grade stainless steel and titanium, the ability of variable angle locking plates to be fixed at different angles allows for better post-surgical results. Trusted by hundreds of surgeons globally, Variolock Locking Plate System has been crafted keeping patient’s comfort and surgical precision in mind.
What is a Variable Angle Locking Plate?
A variable angle locking plate is an advanced orthopedic implant designed to stabilize and fix different types of fractures including the complex intra and extra-articular ones. These variable angle volar locking plates are also ideal for osteotomies of small bones. Unlike conventional locking plates, it allows surgeons to insert screws at multiple angles, typically within a 15°–30° range. This flexibility enhances fixation, especially in complex fractures, osteoporotic bones, and anatomically challenging regions. The locking mechanism ensures a stable construct, reducing the risk of implant loosening while promoting early mobilization. These variable angle plates are widely used in trauma and reconstructive surgeries, providing superior stability and better patient outcomes.
What is a Variable Angle Screw?
A variable angle screw is a specialized orthopedic screw that can be inserted at different angles within a predefined range. Unlike traditional locking screws, which must be placed at a fixed trajectory, variable angle screws offer surgeons the flexibility to optimize screw positioning based on bone quality and fracture pattern. This adaptability improves anchorage in osteoporotic bones, enhances fixation strength, and minimizes complications such as screw pullout or implant failure.
Variolock Locking Plate System Uses
Locking plates serve many purposes. It is used for easy fracture fixation with small incisions, minimal surgical trauma also ensuring minimal bone-implant interface. Even a Variable Angle Plate does not disrupt cortical bone perfusion. These are used as a reliable solution to fracture fixing.
What is the Difference Between a Variable Plate and a Locking Plate?
Variable plate as the name suggests is a special orthopedic plate that allows screws to be fixed at different angles depending on the fracture pattern and severity. On the other hand, locking plate is a trauma plate that allows a fixed construct at a specific angle while providing good stability. Let us have detailed comparison between the two orthopedic locking plates:
| Feature | Variable Angle Locking Plate | Conventional Locking Plate |
| Screw Insertion Angle | Allow fixation at different angles | Fixed screw trajectory |
| Flexibility | Can accommodate different fracture patterns | Less adaptable |
| Bone Contact | Low reliability on bone-to-plate contact | Requires a precise fitting on the bone |
| Application | Ideal for complex fractures | Best for fractures with low complexity |
| Stability | Excellent stability in challenging cases | Good stability but less flexibility |
What is the Difference Between a Variable Compression Plate and a Variable Locking Plate?
Variable Compression Plate
A variable compression plate is designed to apply controlled compression across a fracture site, promoting faster healing. It relies on dynamic compression holes to generate compression and enhance stability.
Variable Locking Plate
In contrast, a variable locking plate focuses on rigid fixation, securing screws at various angles while minimizing micromotion. Variable angle locking plates are preferred for osteoporotic bones and multi-fragment fractures where compression may not be ideal.
