Product Description
Designed with a slim geometry to minimize the risk of irritation to the nearby tendons and nerves of the forearm, ensuring the frame stays flush with the limb.
Utilizes a reinforced bar system that resists the twisting forces of the forearm muscles, maintaining the critical "interosseous space" between the radius and ulna.
Features micro-adjustable universal joints that allow the surgeon to fine-tune the bone alignment in three dimensions after the pins are inserted.
The clamping blocks are optimized for 3.0mm, 3.5mm, and 4.0mm Schanz screws, allowing for a customized fit based on the patient's specific bone diameter.
Specifically indicated for "both-bone" forearm fractures where the bone has splintered. The provides the structural support needed to keep the bones parallel during healing.
Indicated for high-energy injuries where the skin is too damaged for internal plates. The fixator stabilizes the bone from the outside, allowing for wound care and skin grafts.
Indicated for complex injuries where a bone break is combined with a joint dislocation at the wrist or elbow. The fixator maintains the correct length to keep the joints reduced.
Indicated for cases where previous internal surgeries have failed due to infection. The provides stability while the infection is treated and the bone is cleared of bacteria.

The Ulna & Radius External Fixator is a specialized frame used to stabilize the two bones in your forearm (the radius and the ulna). Because these two bones need to twist over each other for you to turn your palm up and down, a break here is very tricky. The uses thin metal pins that go into the bone and connect to a rod on the outside of your arm. It acts as an external splint that is strong enough to hold the bones in place but light enough that you can still use your hand and move your elbow while the fracture heals.
The primary application of the is for the emergency stabilization of "both-bone" forearm fractures. It is applied to provide rigid reduction for Galeazzi fractures where the radius is broken and the wrist joint is dislocated. The fixator is utilize for the application of provisional stability in complex open forearm injuries with significant skin loss. In clinical practice, the application of 3.0mm pins is essential for providing enough grip in the small bones of a child or a small-framed adult. This system serves as a definitive application for managing forearm bone infections where internal metal plates must be removed to allow the bone to heal.
A major advantage of the TOOLMED is its low-profile clamp design, which provides a significant advantage by reducing the risk of the frame catching on clothing or hitting the other arm. The lightweight aluminum bar offers the critical advantage of superior patient comfort, a significant advantage for those who need to wear the frame for several months. The multi-axial joints provide the advantage of a "perfect reduction," a critical advantage for ensuring the radius and ulna are perfectly parallel for palm rotation. Furthermore, the serrated locking mechanism provides the advantage of a "zero-slip" frame, which is a key advantage for maintaining bone length.
Biomechanically, the is engineered to protect the "interosseous space," which is the gap between the two forearm bones. It is biomechanically designed to resist the rotational forces of the muscles that try to pull the bones together. By utilizing a high-stiffness longitudinal bar, the frame biomechanically supports the weight of the hand and wrist, taking the pressure off the fracture site. This biomechanical stability is vital for early finger motion, as it ensures that the movement of the hand does not cause micro-fractures or loosening at the pin sites in the forearm.
The surgical technique involves the percutaneous insertion of two Schanz screws into each of the broken bone segments under X-ray guidance. The longitudinal bar is then connected using the specialized forearm clamps. The surgeon performs a "traction and rotation" maneuver to ensure the bones are aligned and that the patient can still rotate their palm. The technique is finalized by tightening the high-torque bolts on the frame to make it rigid. This process is minimally invasive, meaning there are no large incisions, which helps protect the blood supply to the bone and speeds up the overall healing process.
Postoperative care for the focuses on hand function and pin cleanliness. For the facility, it is critical to assist the patient with "finger-pumping" exercises immediately after surgery to prevent swelling and stiffness. The facility must also provide a strict daily pin-cleaning routine using sterile saline to prevent superficial infections where the pins enter the skin. Patients are taught to monitor for any "clicking" sounds in the frame or redness at the pin sites. Regular X-rays ensure the bones stay in the correct position for the 8 to 12 weeks usually required for a forearm bone to heal completely.
The TOOLMED Ulna & Radius External Fixator is the ideal high-precision solution for forearm trauma. By combining a lightweight, slim design with the mechanical strength needed to preserve arm rotation and bone length, it ensures that even the most complex forearm fractures are held in perfect alignment for a successful and functional recovery.
In many cases, the is placed in a way that allows you to move your wrist and elbow. However, if your break was very close to a joint, your doctor might "span" the joint, holding it still for a few weeks to let the ligaments heal first.
The forearm has many important nerves. Our fixator is designed to allow "safe-zone" pin entry. Your surgeon will use their expertise and X-ray guidance to place the pins far away from the major nerves that control your hand and fingers.
No, the is one of our lightest frames. It is made from high-strength aluminum, so it won't feel like a heavy weight on your arm. Most patients can use a standard sling to support the arm comfortably during the day.
You will likely need to wear shirts with wide sleeves or use shirts that have buttons or snaps down the side. Many patients find that "sleeveless" shirts or modified T-shirts work best while the fixator is in place.
Once your X-rays show the bone has healed, the fixator is removed in the doctor's office. It is a very quick process that usually takes less than 10 minutes. You might feel some pressure as the pins are unscrewed, but it is generally not painful.
