The Herbert screw, a revolutionary design in small bone osteosynthesis, functions as a headless, cannulated compression mechanism specifically configured to achieve rigid internal fixation without prominent hardware interfaces. Structurally, the Herbert screw utilizes two distinct threaded regions with contrasting thread pitches. The distal thread features a wider pitch to facilitate faster progression through the distant cortical or cancellous bone fragment, while the proximal thread possesses a narrower pitch.
As the screw is advanced across the fracture line, the variance in rotational travel speeds between the two threaded portions mechanically draws the bony fragments together. This establishes a controlled compression force directly corresponding to the pitch differential:
Compression Force (F) ∝ (Pitch_distal - Pitch_proximal) * N_rotations
This headless design allows the screw to be countersunk completely beneath the articular cartilage, protecting nearby soft tissue and tendons from frictional damage, which is critical in intra-articular applications such as scaphoid fractures (Herbert Classification Type B and C) and capitellum fractures.
In the European Union and other globally harmonized regulatory jurisdictions, Herbert screws are categorized as Class IIb active/implantable medical devices (under Regulation (EU) 2017/745, commonly known as the MDR). Securing CE certification requires a comprehensive assessment of the technical documentation, biological safety evaluation according to ISO 10993 series, and rigorous quality system maintenance conforming to ISO 13485:2016 standards.
With an advanced, dedicated production facility covering approximately 320㎡, Bonevia leverages highly specialized micro-machining cells, sterile cleanrooms, and automated processing lines. The company maintains an annual export revenue of USD 8–15 million, backed by 6 years of export operations and over 10 years of overall orthopedic industry engineering experience.
We support healthcare providers, clinics, and distributors worldwide, managing a complex distribution ecosystem with more than 850 raw material and logistics partners. This ensures stable raw material supply chains, consistent batch quality, and reliable product delivery to markets in Europe, Southeast Asia, the Middle East, and South America.
To meet shifting clinical demands, our development department—consisting of 85 R&D engineers—introduced 120 new product designs in the past year alone. This capability enables us to provide flexible OEM and ODM customization services for surgical instrument sets and implant geometries.
Our facility utilizes state-of-the-art machinery and rigorous quality control steps to produce high-precision orthopedic implants. Below is the step-by-step manufacturing and inspection flow:
Modern medical procurement departments face pressure to optimize orthopedics budgets while maintaining strict patient safety standards. Navigating MDR requirements, customs protocols, and varying sterilization certificates requires working with suppliers who understand local regulatory environments.
Bonevia supports global sourcing agents by providing transparent material data sheets, batch traceability certificates, and sterilization validations (e.g., Gamma radiation or EO gas compliance) to simplify the importation process.
Operating within major industrial orthopedics clusters in China, Bonevia integrates local precision tooling capabilities, automated manufacturing, and direct sourcing of raw materials. This setup helps reduce lead times for custom orders.
By combining automated CNC processing with an efficient logistics network of 850 partners, we balance cost efficiency with reliable product quality, ensuring quick fulfillment for high-volume orders.
Every surgical market has specific requirements regarding instrument layouts and screw lengths. Our R&D team of 85 engineers collaborates with surgeons and distributors to design customized kits.
Whether you need customized implant geometries, private-label branding (OEM), or modified surgical instruments (ODM), we manage the entire project from CAD modeling to test verification and production.
Our quality assurance program is managed by a team of 35 QA specialists who supervise three main inspection phases:
Herbert Screws are utilized across multiple surgical disciplines where stable compression and a headless profile are critical for joint mobility:
Scaphoid fractures represent the most common carpal bone injuries. The retrograde or anterograde insertion of a cannulated Herbert screw over a guide wire achieves stable fixation across the fracture gap. This compression stimulates bone healing, helping to prevent osteonecrosis of the proximal pole while allowing early range-of-motion therapy.
Displaced fractures of the capitellum or radial head require anatomical reduction and flat, sub-chondral fixation. Because the Herbert screw head sits completely below the articular surface, it does not impinge on the radial head or distal humerus during elbow flexion and extension, helping to preserve joint function.
In distal interphalangeal (DIP) joint arthrodesis and distal metatarsal osteotomies, the micro-screw design provides stable compression in small bone areas. This structural stability minimizes hardware prominence issues beneath the thin skin margins of the foot.
The orthopedic industry is adopting advanced surface treatments, bio-absorbable materials, and digital manufacturing workflows to improve long-term clinical outcomes:
Applying anodic oxidation or calcium phosphate coatings onto titanium implants helps enhance early bone integration, reducing the risk of screw migration or loosening in patients with poor bone quality.
Developing bio-absorbable magnesium alloy compression screws offers initial structural stability before the implant gradually degrades, eliminating the need for a second hardware removal surgery.
Integrating CAD modeling with metal 3D printing allows manufacturers to produce implants with porous structures that match the patient's anatomy, supporting natural bone ingrowth.
