Product Description
The set includes specialized jigs capable of guiding screws in multiple diverging planes, which is essential for capturing small fragments in complex humeral head fractures.
Utilizes high-strength carbon fiber for targeting arms to eliminate metal interference on X-rays, allowing for perfect visualization of the screw-to-nail interface.
Equipped with specialized tactile depth gauges that allow for accurate screw length selection even in soft, cancellous metaphyseal bone, preventing joint penetration.
Features a robust, quick-locking inserter handle that provides the surgeon with exceptional control during nail advancement and rotational alignment.
The set is specifically indicated for fractures where the humeral head is severely fragmented, requiring the high-density, multi-directional locking provided by the Multi-lock system.
Equipped with specialized distal targeting sleeves indicated for fractures extending toward the elbow, allowing for stable anchorage in the distal third of the humerus.
Indicated for geriatric patients where traditional locking is insufficient; the set facilitates the placement of divergent screws that create a "web" of support within the humeral head.
Contains the specialized extraction and reaming tools necessary for revision procedures, providing the precision needed to secure new fixation in compromised bone stock.

The Multi-lock Humeral Intramedullary Nail Instrument Set is a specialized system of high-precision orthopedic tools designed to facilitate the implantation of multi-lock humeral nails. Unlike standard humeral sets, this system is optimized for "Expert" level locking, which involves placing multiple screws in various angles (multi-planar) to achieve maximum stability in the proximal and distal metaphyses. The set includes a sophisticated targeting jig, entry tools, and specialized reamers. Manufactured from medical-grade stainless steel and radiolucent materials, the set provides the necessary interface for surgeons to secure complex fractures that would otherwise require extensive plating. It acts as the mechanical foundation for building a stable, internal load-sharing construct within the humerus.
This instrument set is primarily applied in the surgical treatment of complex fractures of the proximal humerus and the humeral shaft with metaphyseal extension. It is the preferred application for patients with osteoporotic bone where standard screw fixation is likely to fail. The set is applied in both antegrade approaches (inserted through the shoulder) and retrograde approaches (inserted through the distal humerus). In clinical practice, it is utilized for 2-part, 3-part, and certain 4-part proximal humeral fractures. Its multi-planar locking capabilities are also applied in stabilizing segmental fractures and corrective osteotomies for humeral mal-unions, where rotational control is difficult to maintain with traditional nailing systems.
The primary advantage of the TOOLMED Multi-lock Instrument Set is its ability to provide extremely precise fixed-angle stabilization in complex bone geometries. The radiolucent carbon-fiber targeting arm is a significant advantage, as it allows the surgeon to visualize the humeral head and ensure locking screws do not penetrate the joint space. The ergonomic design of the inserters and drivers reduces surgical fatigue and increases tactile feedback, allowing for safer hardware placement. Additionally, the set’s modular design ensures that all components are logically organized, which speeds up the surgical workflow and reduces the margin for error. The durability of the stainless steel reamers ensures consistent, sharp cutting performance over many uses, which is critical for preventing bone necrosis.
Biomechanically, the instrument set allows for the creation of a "three-dimensional" locking construct. By guiding screws in divergent and convergent paths, the tools enable the nail to act as an internal scaffold that captures a larger volume of bone. This "multi-lock" effect significantly increases the pull-out strength of the screws and resists the varus-tilting forces typically seen in humeral head fractures. The precision-reamed canal, created by the set’s flexible reamers, ensures that the nail has optimal contact with the endosteal surface, maximizing the load-sharing potential of the implant. This mechanical stability is crucial for allowing early postoperative rehabilitation and shoulder motion.
The surgical technique begins with the selection of the correct entry point using the set's cannulated awl. The medullary canal is then prepared using the flexible reamers provided in the tray. The multi-lock nail is mounted onto the inserter handle and advanced into the humerus. The multi-planar targeting jig is then securely attached, and specialized sleeves are used to guide the drill bits in the desired planes. After drilling, the depth gauge is used to measure the screw length, and the multi-lock screws are inserted and tightened. The technique is finalized by using the set's dedicated drivers to secure the end cap, ensuring the proximal screws are locked into a single rigid unit for maximum stability.
Postoperative care for the instrument set involves rigorous decontamination and sterilization to ensure long-term precision. After each surgery, the targeting jigs and inserters must be disassembled and cleaned of all biological debris. The cannulated reamers require meticulous manual cleaning with wire brushes followed by ultrasonic cleaning. The set must be sterilized in a steam autoclave at 134°C. For the hospital, regular calibration checks of the multi-planar jigs are essential to ensure the alignment remains within tolerance. Proper maintenance of this set ensures that the high-precision targeting required for multi-lock nails is preserved, preventing surgical delays and maintaining the highest standard of patient safety.
The TOOLMED Multi-lock Humeral Intramedullary Nail Instrument Set is an indispensable tool for surgeons managing complex upper limb trauma. By providing the precision and flexibility required for multi-planar locking, this system ensures that even the most challenging humeral fractures can be stabilized with confidence, leading to better functional outcomes and faster patient recovery.
Our Multi-lock targeting jig supports up to four different screw planes proximally, allowing for divergent fixation that significantly enhances stability in fragmented humeral head fractures.
Yes, the set includes specialized targeting components and trocars designed for a retrograde approach, ensuring stable fixation even for fractures in the distal third of the humerus.
Absolutely. The carbon fiber material used in our jigs is 100% radiolucent, meaning it will not block the surgeon's view of the nail or the bone under X-ray, which is critical for accurate screw placement.
We provide a calibration gauge with the set. If misalignment is suspected, the jig can be checked on the bench before surgery. If it is damaged, we offer individual replacement arms to restore precision.
Yes, our drivers feature a precision-fit Star/Torx or Hex interface that matches our multi-lock screws exactly, ensuring high torque can be applied without damaging the screw head or the driver.
