The Multi-lock Humeral Intramedullary Nail is a highly versatile and secure fixation system designed to treat a wide range of humeral fractures. It is engineered with a unique multi-locking capability, allowing surgeons to place multiple screws both proximally and distally to achieve superior stability, particularly in complex, comminuted, or osteoporotic fractures. The nail’s anatomical design and low-profile head enable a less invasive surgical approach, which can help preserve the soft tissue and blood supply of the humeral head. This robust internal fixation facilitates early functional movement and is crucial for promoting rapid healing and a successful return to a high quality of life.

Product Description
The nail’s design incorporates multiple locking screw options in both the proximal and distal ends, providing enhanced multi-planar and rotational stability for complex fracture patterns.
The nail is anatomically contoured with a slight anterior bow and a specific proximal bend to match the natural shape of the humeral canal, which simplifies insertion and provides a close, stable fit.
The nail is cannulated, which allows for insertion over a guide wire to ensure accurate placement and a minimally invasive surgical technique.
The system is compatible with a dedicated targeting guide to ensure precise and accurate placement of the distal locking screws, which is crucial for achieving stable fixation.
Crafted from a high-quality titanium alloy, the implant offers superior strength, biocompatibility, and fatigue resistance for long-term support and reliable fixation.
The Multi-lock Humeral Intramedullary Nail is primarily indicated for the stable fixation of a wide variety of humeral shaft fractures, including transverse, oblique, spiral, and comminuted fractures.
It is also used for specific fractures in the proximal and distal regions of the humerus, such as humeral neck fractures and supracondylar fractures.
The implant is suitable for the treatment of pathological fractures, impending pathological fractures, and non-unions of the humeral shaft.

The Multi-lock Humeral Intramedullary Nail is a comprehensive fixation system designed to treat fractures of the humerus. This nail is engineered with a unique multi-locking capability that allows surgeons to place multiple screws at various angles in the humeral head and shaft. This feature provides superior fixation in multiple planes, which is particularly beneficial for treating unstable or comminuted fractures by preventing angulation, shortening, and rotation of the bone fragments.
The primary application of the Multi-lock Humeral Intramedullary Nail is for the fixation of fractures of the humeral shaft. This includes simple transverse and oblique fractures, as well as more complex spiral and comminuted fracture patterns.
The nail's design and instrumentation also make it suitable for treating certain proximal humeral fractures, such as those of the surgical neck and diaphyseal fractures with extension into the articular region. It can also be used for the corrective fixation of non-unions and malunions.
Its versatility makes it a go-to choice for trauma surgeons who need a single system to address a broad spectrum of humeral fracture types.
The Multi-lock Humeral Intramedullary Nail offers several key advantages. Its multi-planar locking capability provides superior rotational and angular stability, which is crucial for achieving a successful fixation, especially in challenging fracture patterns and in osteoporotic bone. This enhanced stability can lead to faster bone healing and a reduced risk of implant failure.
The nail’s anatomical design, with its low-profile head and specific curvature, simplifies the surgical technique and can be implanted with a minimally invasive approach. This reduces soft tissue disruption, blood loss, and postoperative pain, allowing for a quicker recovery.
The robust material and design ensure the implant can withstand the forces of early functional movement, which is vital for restoring joint function and getting the patient back to their daily activities quickly.
The biomechanics of the Multi-lock Humeral Intramedullary Nail are centered on providing an internal load-sharing construct that resists angulation and rotation. The nail’s position within the medullary canal of the humerus allows it to support the physiological loads of the arm, reducing stress on the locking screws. The multi-locking feature, with screws placed in various planes, prevents the fracture fragments from collapsing or rotating. This creates a highly stable environment for healing and allows for early, safe range of motion exercises.
The implantation of the Multi-lock Humeral Intramedullary Nail is typically performed via an antegrade (from the shoulder) or retrograde (from the elbow) approach, depending on the fracture location. A small incision is made, and the medullary canal is reamed to the appropriate diameter. The nail is then inserted, and its final position is confirmed with fluoroscopy. Both proximal and distal locking screws are then placed through a dedicated targeting guide to secure the nail and complete the fixation.
This technique is designed to be efficient and precise, minimizing surgical trauma and ensuring accurate implant placement.
The multi-lock feature allows the surgeon to choose the most stable configuration for the specific fracture, optimizing the fixation.
Following a successful Multi-lock Humeral Intramedullary Nail fixation, a structured postoperative care plan is initiated. Due to the inherent stability of the implant, patients are often able to begin early, controlled range of motion exercises to prevent joint stiffness and promote healing. This early mobilization is a key benefit for restoring upper limb function.
Physical therapy is a crucial component of recovery, focusing on regaining muscle strength and full joint mobility.
Regular clinical and radiographic follow-up appointments are essential to monitor fracture healing and ensure the implant remains stable throughout the recovery process, preventing any potential complications.
The Multi-lock Humeral Intramedullary Nail is a highly versatile and effective solution for the treatment of a broad range of humeral fractures. Its anatomical design and comprehensive multi-locking options provide surgeons with the tools to achieve stable, customized fixation. By supporting a minimally invasive surgical technique and promoting early patient mobility, the Multi-lock Humeral Intramedullary Nail leads to excellent clinical outcomes, a faster recovery, and an improved quality of life for the patient.
The multi-lock design allows for superior rotational and angular stability, which is crucial for treating unstable or comminuted fractures of the humerus and for ensuring a stable fixation in osteoporotic bone.
This nail is anatomically designed specifically for the humerus, with a smaller diameter and a different curvature to fit the upper arm bone. The locking options are also tailored to the fracture patterns commonly seen in the humerus.
Yes, the Multi-lock Humeral Intramedullary Nail can be used for fractures of the proximal humerus and certain distal humeral fractures, in addition to shaft fractures, due to its versatile design and locking options.
Yes, the nail is cannulated, which allows for precise insertion over a guide wire and supports a minimally invasive surgical technique.
The nail is designed to be a permanent implant; however, it can be removed once the fracture has fully healed if clinically indicated, such as in cases of implant-related pain or irritation.
