Product Description
The system is designed to facilitate pin insertion in the lateral "safe zones" of the humerus, significantly reducing the risk of injury to the radial nerve during frame application.
Utilizes a heavy-duty 11mm longitudinal bar that provides maximum resistance against the bending and shearing forces caused by the large muscles of the upper arm.
Equipped with micro-serrated universal joints that lock with absolute precision, ensuring that the reduction is maintained even under the weight of the forearm.
The aircraft-grade aluminum frame is hard-anodized for durability and comfort, ensuring the patient can carry the arm without excessive neck or shoulder strain.
Specifically indicated for shattered fractures of the upper arm. The provides the structural framework needed to hold the bone fragments in alignment while they bridge and heal.
Indicated for high-energy injuries with significant skin damage. The fixator stabilizes the bone from the outside, allowing surgeons to perform skin grafts and wound care without internal hardware interference.
Indicated for cases where previous internal surgeries have failed due to infection. The provides stability while the infection is treated, often used in conjunction with antibiotic beads.
Indicated for fractures very close to the shoulder or elbow. The system can be extended to span the joint, providing temporary stability for peri-articular injuries.

The Humeral Shaft External Fixator is a metal frame used to stabilize the bone in your upper arm (the humerus) after a bad break. Because the upper arm is surrounded by heavy muscles, it can be very hard to keep the bone straight with just a sling or a cast. The uses strong metal pins that go through the skin and into the bone, which are then connected to a thick rod on the outside of your arm. This creates a solid support system that holds the bone in the perfect position so it can heal correctly, even when your arm moves.
The primary application of the is for the stabilization of comminuted humeral shaft fractures. It is applied to provide immediate reduction for open upper-arm trauma where the soft tissue is too damaged for internal plates. The fixator is utilize for the application of bone alignment in polytrauma patients who need rapid "damage control" surgery. In clinical practice, the application of multi-axial clamps is essential for avoiding the radial nerve path along the humerus. This system serves as a definitive application for managing humeral non-unions, providing the high-torque stability required for slow bone healing or bone grafting.
A major advantage of the TOOLMED is its 11mm heavy-duty bar, which provides a significant advantage by resisting the powerful pull of the biceps and triceps. The modular clamp design offers the critical advantage of variable pin placement, a significant advantage for avoiding sensitive nerves. The lightweight aluminum construction provides the advantage of making the large frame comfortable for the patient to carry, which is a key advantage for daily life. Furthermore, the serrated joint interfaces provide the advantage of a "permanent lock," a critical advantage for maintaining arm length and rotation.
Biomechanically, the is engineered to handle the complex lever-arm forces of the upper extremity. It is biomechanically designed to distribute the weight of the forearm through the external frame, taking the pressure off the fracture site. By utilizing a high-stiffness longitudinal bar, the frame biomechanically neutralizes the bending and rotational forces caused by shoulder movement. This biomechanical stability is essential for "secondary healing," where the frame allows enough micro-motion to stimulate the growth of a strong bone callus without letting the bone fragments shift out of alignment.
The surgical technique begins with the percutaneous insertion of two or three Schanz screws into the top part of the humerus and two pins into the bottom part, avoiding the radial nerve. The bar is then connected using the multi-axial clamps. The surgeon performs a reduction under X-ray guidance, pulling the arm to restore its natural length. The technique is finalized by tightening the locking bolts on the frame to create a rigid construct. This minimally invasive technique is vital because it preserves the blood supply around the bone, which helps the fracture heal much faster than a large open surgery.
Postoperative care for the focuses on shoulder mobility and pin-site health. For the facility, it is critical to initiate "pendulum exercises" for the shoulder early on to prevent the joint from freezing. The facility must also supervise a strict daily cleaning routine for the pins to prevent infection where the metal enters the skin. Patients are taught to keep the arm supported in a sling when walking to reduce the weight on the shoulder. Regular X-rays ensure the humerus remains straight. Proper care ensures the fixator remains secure for the 10 to 14 weeks typically required for a humerus break to heal.
The TOOLMED Humeral Shaft External Fixator is the ultimate high-strength solution for upper arm trauma. By combining superior mechanical rigidity with a design that prioritizes nerve safety and patient comfort, it ensures that even the most complex humeral fractures are held in perfect alignment, paving the way for a successful recovery of arm strength and movement.
Most patients find it easiest to sleep on their back or on the opposite side, using pillows to prop up the arm with the fixator. Keeping the arm slightly elevated helps reduce swelling and makes the frame feel less heavy during the night.
The is designed to allow pins to be placed in "safe zones" away from the radial nerve. Your surgeon uses their anatomical knowledge and X-ray guidance to make sure the pins are safely away from any nerves or major blood vessels.
Yes, in most cases, the fixator only covers the shaft of the bone, leaving your elbow and shoulder free to move. In fact, moving your elbow and hand is very important to keep your blood flowing and prevent your muscles from getting weak.
A small amount of clear fluid is normal. However, if the fluid is yellow, smells bad, or if the skin is very red and hot, you should contact your doctor. These are signs of a minor infection that can usually be treated with cleaning or antibiotics.
No, removing the fixator is a quick procedure that can often be done in the clinic with a local anesthetic. The pins are unscrewed, and the small holes in the skin usually close up and heal within a week or two.
