The Ulna & Radius Locking Plate system is specifically designed for the challenging treatment of diaphyseal (midshaft) fractures of the forearm, which often involve both the radius and the ulna. Restoring the precise length, alignment, and critical rotation of both bones is paramount for functional recovery. These plates are anatomically contoured and offered in various lengths to span the fracture site appropriately. Constructed from high-strength Titanium Alloy (Ti6Al4V ELI), the system features Locking Technology alongside combination holes. The locking function ensures high stability, particularly in comminuted patterns or poor bone quality, while the combi-holes allow for traditional compression when needed. The TOOLMED Ulna & Radius Locking Plates provide the rigid internal fixation necessary to withstand significant muscular forces and promote direct bone healing, restoring the complex mechanics of the forearm.

Product Description
Plates are pre-bent to match the natural bows (radial and ulnar) of the forearm bones, essential for accurate rotational alignment and minimizing the risk of synostosis (unwanted bone bridging).
Engineered with a low-profile cross-section and smooth edges to reduce the risk of irritation to the overlying muscles and subcutaneous tissues of the forearm.
Allows the surgeon to utilize the plate for compression (non-locking screws) for simple fracture patterns and locking screws for stable fixed-angle constructs in complex or comminuted fractures.
Made from Ti6Al4V ELI, providing high fatigue strength and biocompatibility necessary to withstand the continuous, high-intensity loads exerted by the forearm musculature.
Primary indication for open reduction and internal fixation of displaced and unstable midshaft fractures involving both the radius and the ulna.
Used individually for displaced isolated fractures, such as Nightstick fractures of the ulna or single-bone radius shaft breaks.
Indicated as the foundational fixation for the primary bone in complex fracture-dislocations where restoration of length and stability is critical.

The Ulna & Radius Locking Plate system is a set of titanium plates used to fix broken long bones in the forearm. The forearm is unique because it is composed of two bones (ulna and radius) that must rotate around each other. These plates are anatomically curved and rigidly fixed to ensure that when the bones heal, they retain their correct length and alignment, preserving the critical ability to turn the palm up and down.
These plates are primarily used for high-energy trauma that breaks the midshaft of one or both forearm bones. Restoring the integrity of the forearm is crucial because this region powers the hand and wrist. The locking plate system is essential for providing strong stability against the pull of the massive forearm muscles.
The key advantages are versatility and rigid rotational control. The combination of compression (using non-locking screws) and fixed-angle stability (using locking screws) allows the surgeon to treat diverse fracture patterns effectively. Furthermore, the anatomic contouring ensures that the radius maintains its essential bow, which is critical for full forearm rotation.
Biomechanically, these plates act as neutralization or compression plates. In comminuted fractures, the plate functions as a bridging device, resisting bending and twisting forces (torsion) to allow bone growth. The locking mechanism transforms the construct into a fixed-angle device, preventing loss of reduction even if the patient has poor bone quality.
Fixation of both bones requires two separate, precise surgical approaches to avoid damage to surrounding nerves and vessels. The surgeon first restores the bone length and rotational alignment. The plate is then applied to the tension side of the radius and the posterior or subcutaneous border of the ulna, secured with a combination of cortical and locking screws.
Rigid fixation allows for early mobilization. The primary focus of therapy is regaining the full range of forearm rotation (pronation and supination), as well as elbow and wrist motion. Immobilization is kept minimal, emphasizing a rapid transition to functional use.
The Ulna & Radius Locking Plate system provides the gold standard of care for forearm shaft fractures. By ensuring anatomical alignment and rigid titanium stability, it maximizes the likelihood of fracture healing and complete restoration of the complex rotational function of the arm.
If the radius and ulna are not fixed correctly (e.g., incorrect length or rotation), the complex mechanics that allow the forearm to twist (pronation and supination) are compromised, leading to permanent functional impairment.
Synostosis is the unwanted healing of the radius and ulna together, which permanently blocks rotation. These plates are designed to be low-profile and correctly positioned on the bone to minimize soft tissue trauma, which is a key factor in preventing this complication.
Forearm fractures in children are typically treated non-surgically or with intramedullary nailing. Plating is usually reserved for adolescents with closed growth plates or complex injuries.
No. The radius plate is specifically contoured to match the natural radial bow, and the ulna plate is straighter. They must be used on the correct corresponding bone.
For adult patients, these plates are designed to be permanent. They are only removed if they cause significant pain, soft tissue irritation, or if an infection occurs.
