4.5MM Tapered Threaded Pins | Cortical Shaft Tapered 4.5-3.5MM



This pin features a tapered shaft that transitions from a 4.5mm diameter at the threaded end to 3.5mm at the opposite end. The design facilitates gradual insertion into cortical bone, reducing the risk of bone splitting and ensuring a snug fit. The threads are engineered to provide optimal grip within the bone, enhancing stability during the healing process.
Material Composition:
These pins are typically manufactured from:
Medical-Grade Stainless Steel (e.g., AISI 316L): Offers excellent strength, corrosion resistance, and biocompatibility.
Titanium Alloys (e.g., Ti-6Al-4V): Provide superior biocompatibility, reduced weight, and excellent corrosion resistance, making them ideal for long-term implantation.
The choice of material depends on the specific clinical requirements and surgeon preference.
- External Fixation Systems: Used as fixation elements in external fixators (monolateral or circular like Ilizarov frames). The tapered design provides strong anchorage in cortical bone, especially in pediatric or osteoporotic patients.
- Enhanced Cortical Purchase: The tapered shaft improves thread-to-bone engagement—Ø4.5 mm threads anchor in the outer cortex, while the Ø3.5 mm shaft reduces stress at the bone entry point, helping avoid microfractures or cracking.
- Fracture Stabilization: Commonly used in tibial, femoral, humeral, or radius/ulna fractures where external fixation is needed. Provides temporary or definitive stabilization for open fractures, especially when internal fixation is contraindicated.
- Deformity Correction: Used with hexapod or ring fixators (e.g., Taylor Spatial Frame) in limb lengthening or angular correction procedures. Ensures stable and controlled fixation during gradual adjustments.
- Pediatric Orthopedic Applications: Suitable for children due to smaller size and lower bone trauma risk. Tapering helps minimize pin tract infections and promotes easier insertion with better cortical grip.
- Tapered Shaft Design: The gradual reduction from 4.5 mm to 3.5 mm allows for controlled insertion and improved stress distribution within the bone.
- Enhanced Bone Purchase: The threaded section ensures strong engagement with cortical bone, providing reliable fixation.
- Reduced Insertion Trauma: The tapered design minimizes the force required for insertion, decreasing the likelihood of bone damage.
- Versatile Length Options: Available in lengths of 100 mm and 120 mm, accommodating various anatomical and procedural requirements.
- Precision Engineering: Manufactured to exacting standards to ensure consistency and reliability in surgical applications.
