Explore our premium range of orthopaedic surgical solutions, including spinal fixation systems, trauma plates, and high-precision instruments.
Optimizing mechanical fixation and bone-to-implant load transfer in low-density trabecular bone microarchitecture.
In modern orthopedic trauma and reconstructive surgery, cancellous bone screws are specialized medical implants designed to secure osteosynthesis devices or fragments within soft, spongy trabecular bone tissue. Unlike cortical bone, which features high density and mechanical stiffness, cancellous bone is highly porous and cellular. Consequently, achieving structural stability demands a screw design characterized by a larger outer thread diameter, a deeper thread profile, and a wider pitch. These structural configurations maximize the surface contact area, enhancing the pull-out strength and resistance of the implant under physiological loading conditions.
Zynfuse Medical Technology Co., Ltd. addresses the complexities of metaphysical and epiphyseal bone stabilization by manufacturing surgical-grade titanium alloy (Ti-6Al-4V ELI) and high-nitrogen stainless steel cancellous screws. Designed to deliver superior bio-compatibility, fatigue strength, and corrosion resistance, our products are trusted by surgeons worldwide for critical joint reconstructions, osteotomies, and fracture fixation surgeries.
Features an expanded outer-to-core diameter ratio, allowing for a substantial volume of trabecular bone to sit between the threads, drastically reducing the risk of construct shear failure.
Configured with cutting tips that evacuate bone debris during insertion, minimizing thermal necrosis and bone resorption while maintaining optimal local tissue density around the threads.
Proprietary anodization and electrochemical polishing form a uniform titanium oxide surface layer, boosting resistance against fretting corrosion and accelerating osseointegration.

Where and how our implants are utilized in reconstructive and trauma procedures.
Cannulated cancellous screws (often applied in groups of three in a triangular pattern) provide stable compression across femoral neck fractures while preserving blood supply to the femoral head.
Supports the stabilization of split-depression fractures of the tibial plateau, anchoring locking plates or washer assemblies into the spongy bone below the articular surface.
Provides strong lag compression for arthrodesis of the subtalar, talonavicular, and calcaneocuboid joints, helping promote solid bone fusion.
