The Hindfoot Fusion Ankle Nail is a specialized intramedullary implant engineered for arthrodesis, or surgical fusion, of the joints in the ankle and hindfoot. This system provides a robust, load-bearing internal fixation to hold the bones of the distal tibia, talus, and calcaneus in a stable, anatomical position, allowing them to fuse together into a single bone mass. Unlike fracture nails, its primary purpose is to provide long-term stability and compression to promote a high rate of successful fusion. This procedure is a definitive solution for severe arthritis, deformities, and instability, leading to significant pain relief and improved patient function.

TOOLMED
Product Description
The nail’s design features a specific bend and distal geometry to conform to the natural alignment of the tibial, talar, and calcaneal canals, which facilitates optimal placement and stability.
The system allows for powerful compression across the fusion sites, which is critical for promoting bone-to-bone contact and a high rate of successful arthrodesis.
Multiple locking screw options, including proximal and distal holes, provide superior rotational and angular stability to prevent motion at the fusion sites during the healing process.
The nail is cannulated, which allows for insertion over a guide wire to ensure accurate placement and a minimally invasive surgical technique.
Crafted from a high-quality titanium alloy, the implant offers exceptional strength and biocompatibility, designed for the long-term support required for a successful fusion.
The Hindfoot Fusion Ankle Nail is primarily indicated for patients with severe post-traumatic ankle or hindfoot arthritis that has not responded to conservative treatments.
It is used as a definitive treatment for advanced cases of Charcot neuroarthropathy of the ankle and hindfoot, providing the robust stability required for fusion in compromised bone.
The implant is suitable for salvage procedures following a failed total ankle replacement and for the correction of severe, rigid foot and ankle deformities.

The Hindfoot Fusion Ankle Nail is a specialized intramedullary implant used for arthrodesis, which is the surgical fusion of bones. This nail is specifically designed to provide stable, long-term internal fixation for the joints of the ankle and hindfoot, primarily the tibiotalar, subtalar, and calcaneocuboid joints. The goal of the procedure is to eliminate painful motion in these severely damaged joints by encouraging the bones to grow together, creating a single, stable unit and providing significant pain relief for the patient.
The primary application of the Hindfoot Fusion Ankle Nail is for the treatment of severe and chronic conditions of the ankle and hindfoot. This includes end-stage arthritis, whether from trauma, rheumatoid disease, or other degenerative conditions.
The nail is also a preferred solution for complex cases like Charcot neuroarthropathy, a progressive condition that leads to severe joint destruction, as well as for salvage procedures following a failed total ankle replacement or in cases of severe, rigid foot and ankle deformities.
The stable fixation provided by the nail is crucial for achieving high fusion rates in these challenging clinical scenarios.
The Hindfoot Fusion Ankle Nail offers several key advantages for ankle and hindfoot arthrodesis. The intramedullary position of the nail provides robust and durable fixation that is well-suited to withstand the high biomechanical loads of the lower limb. The system’s ability to provide powerful compression across the fusion sites is a critical factor for stimulating bone healing and ensuring a high rate of successful fusion.
The minimally invasive surgical approach can lead to less soft tissue damage, reduced blood loss, and a faster postoperative recovery for the patient. Unlike a joint replacement, which can wear out over time, a successful fusion is a definitive, permanent solution for pain and instability.
The nail's design ensures a strong, stable construct that can support the patient's weight during the healing process, reducing the need for extensive external bracing and allowing for a more predictable recovery.
The biomechanics of the Hindfoot Fusion Ankle Nail are centered on creating a rigid, compressive construct. Once implanted, the nail acts as a central axis of stability, preventing motion in the fused joints. The proximal and distal locking screws secure the nail to the tibia and hindfoot, resisting rotational and bending forces. The system also allows for compression, which pulls the prepared bone surfaces together. This compression is a powerful biological stimulus for bone healing and is essential for achieving a solid arthrodesis, as it minimizes the gap between the bones and promotes rapid integration.
The implantation of the Hindfoot Fusion Ankle Nail typically begins with a thorough debridement of the ankle and subtalar joints to remove cartilage and expose the bleeding bone surfaces, which is necessary to prepare for fusion. A guide wire is then inserted from the heel, through the talus and into the tibia. The medullary canal is reamed, and the nail is inserted over the wire. The surgeon then compresses the fusion sites, and locking screws are placed both proximally in the tibia and distally in the calcaneus and talus to provide multi-planar stability. The final position is confirmed with fluoroscopy.
Following a successful Hindfoot Fusion Ankle Nail procedure, patients are typically immobilized in a splint or cast and are instructed to remain non-weight-bearing for a specific period, usually several weeks. Once early healing is confirmed, a progressive weight-bearing protocol is initiated. Physical therapy is a crucial component of recovery, focusing on strengthening the surrounding muscles and regaining mobility in the unfused joints. Regular clinical and radiographic follow-up appointments are essential to monitor the progress of the bone fusion and ensure the implant remains stable.
The Hindfoot Fusion Ankle Nail is a highly effective and reliable solution for the treatment of end-stage ankle and hindfoot pathologies. By providing a robust, compressive intramedullary fixation, the system promotes a high rate of successful arthrodesis, leading to significant and lasting pain relief for patients. The nail's advanced design and streamlined surgical technique make it a preferred option for surgeons seeking a definitive and durable solution for complex foot and ankle deformities, ultimately improving patient quality of life.
A fusion nail is designed to hold bones in a fixed position to allow them to fuse together, whereas a fracture nail is designed to stabilize bone fragments to allow a fracture to heal. A fusion nail often provides compression across joints, a feature not found in most fracture nails.
Fusion is often recommended for patients who have severe deformities, significant bone loss, or an active infection, or who have high-demand activity levels. It provides a permanent, highly stable solution that eliminates pain by removing joint motion, while a joint replacement can wear out over time.
Bone fusion typically takes several months, though the time can vary depending on the patient's overall health and the complexity of the case. While some signs of fusion may be seen in a few weeks, a solid fusion can take 6-12 months to achieve.
The nail is designed to be a permanent implant; however, it can be removed once a solid fusion is confirmed if the patient experiences discomfort or irritation from the hardware.
Yes, a fusion of the ankle and hindfoot joints will eliminate motion in those specific joints. However, the goal is to relieve pain and improve stability, which can ultimately lead to better overall function and walking ability than before the surgery.
