High-Purity Titanium Constructs for Controlled Limb Lengthening
The CytroFIX® Intramedullary Lengthening Nail (Magnetic) by Cytronics (an INVAMED orthopedic division) is specifically engineered for limb-lengthening procedures in the femur (and, in some cases, the tibia). By integrating magnetic gear technology within a high-purity titanium intramedullary design, surgeons can achieve controlled, noninvasive post-operative adjustments, minimizing patient discomfort and simplifying limb distraction protocols. Magnetic Lengthening Mechanism
Features an internal magnetic gear system activated by an external remote controller.
Surgeons and patients can adjust distraction increments without invasive manipulation, fostering a precise and comfortable lengthening process.
High-Purity Titanium Construction
Fabricated from Ti-6Al-4V ELI or equivalent high-grade titanium, ensuring excellent biocompatibility and strength-to-weight ratio.
Minimizes the risk of allergic reactions and supports a stable environment for regenerating bone in distraction segments.
Intramedullary Stability & Load Sharing
The nail is placed within the medullary canal, providing robust mechanical support while the regenerate bone forms during distraction osteogenesis.
Offers alignment benefits similar to conventional intramedullary nails, with added lengthening functionality.
Precision Distraction Control
External remote controller adjusts nail length in small increments (e.g., ~0.25 mm per activation), enabling surgeons to tailor distraction rates to patient-specific protocols and healing responses.
Reduced risk of over-distraction or inconsistent gap formation, improving outcomes in limb-length discrepancies, post-traumatic deficits, and certain congenital deformities.
Versatile Clinical Indications
Indicated for limb-lengthening procedures in cases of congenital short stature, post-traumatic malunion, or nonunion with length deficits.
Potentially suitable for femoral and/or tibial applications, depending on surgeon preference, patient anatomy, and the device’s length/diameter range.
Contraindications
Active local or systemic infections, inadequate canal diameter, or severely compromised bone stock preventing stable fixation.
Certain comorbidities (e.g., severe osteoporosis, vascular insufficiency, neuromuscular disorders) may require alternative approaches or caution.
