What are cortical bone screws (cortex screws) used for in orthopedic surgery?

Cortical bone screws are designed with fine threads and a smaller pitch to anchor securely into dense cortical bone. They are primarily used for interfragmentary compression, plate fixation (DCP, LC-DCP), and fracture stabilization in long bones such as the femur, tibia, humerus, radius, and ulna.

What medical-grade materials are used for HCM Orthocare cortex screws?

Our cortex screws are precision-machined from biocompatible Titanium Alloy Ti6Al4V (ASTM F136 standard) and Stainless Steel 316L (ASTM F138 standard), offering high tensile strength, fatigue resistance, and exceptional biocompatibility.

Are self-tapping cortical screws available from HCM Orthocare?

Yes, we manufacture both self-tapping and non-self-tapping cortical screws. Self-tapping designs feature fluted tips that cut their own thread trajectory during insertion, reducing operative time and minimizing thermal necrosis.

What sizes and diameters of cortex screws do you manufacture?

We manufacture a comprehensive range of cortical screw diameters including 1.5mm, 2.0mm, 2.7mm, 3.5mm, and 4.5mm, with lengths ranging from 10mm to 110mm in Hex, Star/Torx drive, and recessed configurations.

Do you provide sterile packaging and regulatory compliance for export?

Yes. All screws are produced under ISO 13485 cleanroom standards, CE certified, and available in double-barrier sterile Tyvek pouch packaging or non-sterile bulk export packaging with full batch traceability.

Biomechanical Excellence & Product Features

Designed in collaboration with clinical orthopedic experts, our cortical screws feature optimized pitch and core diameter ratios to ensure maximal pull-out force and torque transmission in cortical bone structures.

Optimized Thread Profile

Features a small thread pitch and shallow thread depth tailored specifically for hard cortical bone, delivering maximum holding power and preventing micro-stripping.

Self-Tapping & Non-Self-Tapping

Available with cutting flutes for self-tapping insertion to shorten surgical procedure time, as well as conventional non-self-tapping formats for pre-tapped bone tunnels.

Medical-Grade Alloys

Fabricated from ISO-certified Ti6Al4V (ASTM F136) and Stainless Steel 316L (ASTM F138) to guarantee absolute tissue neutrality and corrosion resistance in long-term implantation.

Precision Drive Recess

Incorporates Hexagonal, Star Drive (Torx-compatible), and Cruciform socket drives to minimize driver slippage, cam-out, and screw head stripping during high-torque insertion.

Anatomical Profile & Countersinking

Low-profile, smooth spherical screw head designs prevent soft tissue irritation while facilitating flush seating into dynamic compression plates (DCP) and locking plates.

Strict Batch Traceability

100% optical inspection and dimensional verification. Each export batch carries full raw material heat traceability and laser-etched identification codes.

Clinical Applications in Orthopedic Trauma

Cortical bone screws are the workhorse fasteners in reconstructive and emergency trauma surgery. Primary operative applications include:

✔
Diaphyseal Long-Bone Fractures: Securing compression and neutralizing plates to the femur, tibia, humerus, radius, and ulna.
✔
Interfragmentary Compression (Lag Screw Technique): Inserting cortical screws across simple spiral or oblique fracture lines to generate direct bone-on-bone compression prior to plating.
✔
Pelvic & Acetabular Fixation: Anchoring specialized reconstruction plates in complex pelvic ring injuries.
✔
Osteotomy Fixation: Securing alignment osteotomies in pediatric and adult corrective extremity surgeries.

Frequently Asked Questions

Common technical and procurement questions regarding our Cortical Screws.

What is the difference between a cortex screw and a cancellous screw? +

Cortex screws feature fine threads, a smaller pitch, and a higher core-to-outer diameter ratio engineered to anchor firmly into dense cortical bone. Cancellous screws have a deeper thread depth and wider pitch designed to grip soft, porous cancellous bone tissue typical of joint epiphyses.

Which material is preferable: Titanium Ti6Al4V or Stainless Steel 316L? +

Both materials meet rigid clinical standards. Titanium Ti6Al4V offers a lower elastic modulus (closer to natural bone), lighter weight, MRI compatibility, and superior biocompatibility. Stainless Steel 316L provides higher initial rigidity, economical cost, and seamless integration with existing stainless steel plating systems.

Can cortical screws be used as lag screws? +

Yes. Partially threaded cortical screws or fully threaded cortical screws (when overdrilling the near cortex) can be inserted across a fracture line to achieve interfragmentary compression via the lag screw principle.

What are the packaging options for international buyers? +

We supply cortical screws either in double-barrier Tyvek sterile packaging ready for direct surgical use or non-sterile protective packaging designed for hospital sterilization kits and distributor stock.
