The VA (Variable Angle) Distal Radius Locking Plate is a state-of-the-art orthopedic implant system engineered for the treatment of a wide range of distal radius fractures. Its most significant feature is the variable angle locking technology, which allows surgeons to place screws at a range of angles (up to +/- 15°) from the central axis. This flexibility is invaluable for securely capturing small bone fragments and creating a stable subchondral support "raft" beneath the joint surface. The plate is anatomically contoured for a precise fit on the volar (palm-side) surface of the distal radius and features a low-profile design to minimize soft tissue and tendon irritation.

Product Description
The system allows for multi-directional screw placement, providing surgeons with the flexibility to capture and stabilize small, difficult-to-fix bone fragments in the distal metaphysis and articular surface.
The plate is specifically designed to match the complex anatomy of the distal radius, with a head width of 22mm that provides optimal support and a low-profile fit for the volar surface.
The variable-angle screws can be directed to create a "raft" of support beneath the joint surface, effectively buttressing and maintaining the reduction of intra-articular fragments.
The plate’s thin, low-profile design minimizes irritation to the surrounding soft tissues and tendons, which is crucial for reducing patient discomfort and promoting early rehabilitation.
Crafted from a high-quality titanium alloy, the implant offers exceptional strength, biocompatibility, and fatigue resistance for reliable, long-term fixation.
The VA Distal Radius Locking Plate is primarily indicated for the stable fixation of a wide range of fractures of the distal radius, including both extra-articular and intra-articular fractures.
It is an ideal solution for comminuted (multiple fragments) fractures and fractures in osteoporotic bone, where the variable angle locking technology provides superior screw purchase and stability.
The implant is also suitable for the treatment of non-unions and malunions (improperly healed fractures) of the distal radius, providing the necessary stability for corrective procedures.

The VA Distal Radius Locking Plate is a highly specialized orthopedic implant for the internal fixation of wrist fractures. The "VA" stands for Variable Angle, a revolutionary feature that allows the surgeon to change the trajectory of the locking screws within a specific range. This provides a significant advantage over traditional fixed-angle locking plates, as it enables the surgeon to precisely target and secure small bone fragments, especially in comminuted or intra-articular fractures. The plate's design, including its 22mm head width, is tailored to the specific anatomical requirements of the distal radius, making it an advanced solution for complex wrist injuries.
The primary application of the VA Distal Radius Locking Plate is for the fixation of fractures of the distal radius. These fractures are the most common in the upper extremity and often involve the joint surface. The variable angle technology is particularly valuable for intra-articular fractures, as it allows surgeons to place screws in a multi-directional pattern to support and reduce the articular fragments. This technique is often referred to as a "subchondral raft" and is critical for restoring the smooth joint surface and preventing post-traumatic arthritis. The plate is also used for extra-articular fractures, where its stability allows for early mobilization and a faster return to function.
The VA Distal Radius Locking Plate offers several key advantages. The variable angle locking technology provides unmatched surgical flexibility, allowing the surgeon to customize the screw placement to the individual fracture pattern. This leads to a more secure and stable construct, even in challenging cases. The plate's low-profile design minimizes irritation to the numerous tendons and nerves in the wrist, reducing patient discomfort and the risk of complications. The enhanced stability provided by the locking system allows for early range of motion exercises, which is essential for preventing wrist stiffness and restoring full function. This leads to a faster recovery and better overall patient outcomes.
The biomechanics of the VA Distal Radius Locking Plate are based on creating a rigid, multi-directional support platform for the distal radius. Unlike a traditional fixed-angle plate, the variable angle screws can be directed to create a scaffold-like structure that buttresses the joint surface. This "subchondral raft" prevents the collapse of articular fragments under axial load. The entire plate-screw construct acts as a single, stable unit that is highly resistant to bending, compression, and torsional forces. This superior stability allows the bone to heal in proper alignment, which is crucial for a successful long-term outcome.
The implantation of the VA Distal Radius Locking Plate is typically performed via a volar (palm-side) approach. After the surgeon reduces the fracture, the pre-contoured plate is placed on the bone's surface. Using a dedicated targeting guide, the surgeon can then select the optimal screw trajectories, angling the screws to capture specific fragments. The locking screws are then threaded into the plate, creating the rigid fixed-angle construct. The procedure is designed to be minimally invasive, with care taken to protect the surrounding tendons and nerves, and final placement is confirmed with fluoroscopy.
Following a successful VA Distal Radius Locking Plate fixation, a structured postoperative care plan is initiated. Due to the high stability of the fixed-angle construct, patients are often able to begin early range of motion exercises of the fingers and wrist within the first few days. Physical therapy is a crucial component of recovery, focusing on regaining full strength and mobility. Regular clinical and radiographic follow-up appointments are essential to monitor fracture healing and ensure the implant remains stable throughout the recovery process.
The VA Distal Radius Locking Plate is a highly effective and reliable solution for the treatment of a wide range of distal radius fractures. Its innovative variable-angle technology, combined with an anatomical design, provides surgeons with a powerful tool for achieving stable, customized fixation. By promoting high stability, anatomical reconstruction, and facilitating early patient mobility, the VA Distal Radius Locking Plate leads to excellent clinical outcomes, a faster recovery, and a restored quality of life for the patient.
The VA feature gives the surgeon the flexibility to place screws at various angles, which is crucial for securely capturing and stabilizing small, comminuted bone fragments in the distal radius. This allows for a more customized and stable fixation than a standard fixed-angle plate.
A standard locking plate has holes that only accept screws at a fixed angle. The VA plate has specially designed holes that allow for a range of screw trajectories, giving the surgeon greater control to address complex fracture patterns.
Plates are used for fractures that are unstable, severely displaced, or involve the joint surface. Surgical fixation with a plate restores the correct length and alignment of the bone, which is crucial for preventing chronic pain and arthritis.
The plate is designed to be a permanent implant. However, it can be removed once the fracture has fully healed if the patient experiences pain or irritation from the hardware.
With stable fixation from a VA locking plate, many patients can begin early range of motion exercises shortly after surgery. Full bone healing typically takes 6-12 weeks, with a complete return to normal activities and full function taking several months of rehabilitation.
