Global-standard titanium implants engineered for structural integrity, high rotational stability, and streamlined surgical fixation.

The Engineering Science Behind Intramedullary Nails

Intramedullary (IM) nailing stands as the gold standard for the internal fixation of long-bone diaphyseal fractures. By acting as a load-sharing device, IM nails align bone fragments from within the medullary canal, facilitating early weight-bearing and accelerating callusal bone healing.

Unlike rigid plate-and-screw constructs that act as load-bearing structures and can cause stress shielding, an intramedullary nail provides stable mechanical alignment while allowing controlled micro-motion. This stimulates secondary endochondral ossification. Key elements such as interlocking proximal and distal screws secure rotational alignment and length maintenance in complex comminuted or unstable fractures.

For orthopedic surgeons and clinical procurement coordinators, selecting the appropriate implant system requires strict evaluation of material purity, tensile strength, fatigue resistance, and anatomical geometries. The choice between titanium alloys and medical-grade stainless steel significantly impacts biocompatibility, elasticity matching, and post-implantation diagnostic compatibility (e.g., MRI artifacts).

Mechanical Bio-Compatibility

Constructed from Ti-6Al-4V ELI (Grade 5 ASTM F136), our intramedullary systems closely mimic the elastic modulus of cortical bone, minimizing stress shielding and maximizing corrosion resistance.

Rotational & Axial Control

Advanced multi-planar interlocking configurations provide superior torque transmission and resist axial shortening, providing optimal stabilization of metaphyseal-diaphyseal transitions.

Cannulated and Solid Variants

Offering both reamed cannulated nails for guided wire application and solid nails for unreamed techniques to match varying clinical protocols and reduce infection risks.

End-to-End Advanced Processing Flow

Every implant undergoes a precise, multi-stage production sequence inside our advanced facility to ensure absolute geometric accuracy and biomechanical stability.

China's Manufacturing Value Proposition & Global Compliance

China's medical implant manufacturing sector has evolved into a global center for high-tech machining and raw material access. Our facility integrates raw materials sourced from medical-grade titanium specialists with precision processing machinery, resulting in a competitive cost-to-quality ratio.

By conducting all operations in-house—from initial Swiss-type lathe turning and Wire EDM cutting to laser marking and sterile-barrier packaging—we cut down operational waste. This vertical integration allows Bonevia to offer B2B procurement terms that support distributors and healthcare groups worldwide without compromising on material performance.

Quality assurance is maintained by a specialized team of 35 quality control professionals. Our testing protocol spans three distinct levels:

  • Incoming Material Verification: Complete spectral analysis and mechanical tensile testing on raw bar stocks to guarantee compliance with ASTM F136 (Ti-6Al-4V ELI).
  • In-Process Control (IPC): Automatic coordinate measuring inspections and thread gauging at every active machining step.
  • Final Sterility and Physical Validation: Bioburden testing, surface roughness analysis (Ra < 0.4 μm), and fatigue testing under simulated load profiles.
Compliance Parameters Bonevia Technical Standard Clinical Relevance
Material Standard ASTM F136 / ISO 5832-3 (Ti-6Al-4V ELI) Minimized allergy risk, high fatigue life
Biocompatibility ISO 10993 Certified Zero cytotoxic responses, long-term safety
Sterility Level SAL 10-6 (EtO / Gamma Option) Prevents implant-associated osteomyelitis
Surface Quality Anodization, Ra < 0.4 μm Decreases soft-tissue attachment, speeds recovery
Precision Margin ± 0.01 mm CNC Tolerance Precise instrumentation fit, smooth locking

Elastic Nails (TENS) Pediatric Long Bones (Femur, Tibia, Forearm) Symmetrical three-point mechanical stability Frictional elasticity Avoids damage to growth plates (physeal preservation)

Pediatric Trauma & Titanium Elastic Nails (TENS)

Managing pediatric long-bone fractures demands a specialized biomechanical approach. Because children have active growth plates (physes), traditional rigid locking nails are contraindicated in patients with open growth plates due to the risk of premature physeal closure or avascular necrosis.

Our Pediatric Titanium Elastic Nails (TENS) leverage the mechanical principles of symmetric three-point fixation. By inserting two elastic titanium nails opposingly, the implants generate a balanced force system that resists bending and rotation. This construct permits micro-motion, which supports rapid periosteal callusal formation while protecting the epiphyseal plates.

Our TENS system is available in diameters from 1.5mm to 4.0mm to support varying medullary diameters. Made from Grade 5 titanium, these nails offer the necessary flexibility for retrograde or antegrade insertion while retaining structural memory and axial load stability.

Frequently Asked Questions

Technical and regulatory insights for hospital procurement officers, medical distributors, and surgical consultants.

What raw material grades are used in Bonevia intramedullary nails?
Our intramedullary nails are manufactured from Ti-6Al-4V ELI (Extra Low Interstitial) Titanium Alloy, conforming to ASTM F136 and ISO 5832-3 standards. This medical-grade alloy provides high tensile strength, excellent fatigue limits, and a lower elastic modulus than stainless steel, reducing the risk of stress shielding.
Can you provide OEM/ODM customization for specific instrumentation sets?
Yes. With an R&D team of 85 engineers, we provide OEM and ODM services. We can customize the dimensions of the intramedullary nails, modify screw hole positions, and redesign targeting instruments to fit your hospital group’s surgical preferences or regional anatomical standards.
Are the implants shipped sterile or non-sterile?
We offer both sterilized and non-sterilized configurations. Non-sterilized titanium alloy implants are double-bagged in protective packaging and must undergo autoclaving at the healthcare facility prior to surgical use. Sterilized options utilizing Ethylene Oxide (EtO) or Gamma irradiation are available upon agreement.
How does Bonevia support local registration and regulatory compliance?
We support global medical device distributors by providing standard technical dossiers, including raw material melt certificates, biocompatibility test results (ISO 10993), sterilization validation documentation, and ISO 13485 quality control certificates. This facilitates the local Ministry of Health registration processes.
What is the standard warranty and post-purchase traceability protocol?
We provide a 1-year product warranty. Each implant is marked with a traceable batch and serial code using laser engraving. This provides complete material tracking back to the original raw titanium slab, in line with ISO 13485:2016 safety guidelines.
