3.5mm Cortical Screw | Titanium & SS | Small Fragment System for Trauma Surgery

High-Performance 3.5mm Cortical Screw for Small Fragment Fixation

At OrthoPro, we are dedicated to advancing the standard of care in orthopedic trauma surgery. Our 3.5mm Cortical Screw is a fundamental element of the Small Fragment System, widely recognized as the “gold standard” for treating fractures in long bones of the upper and lower extremities. Designed for B2B clients, including hospital procurement departments and medical device distributors, our screws combine precision engineering with cost-effective manufacturing.

The OrthoPro 3.5mm cortical screw is specifically designed to provide strong fixation in cortical bone. Unlike locking screws that rely on a threaded head, this cortical screw utilizes a spherical head to allow for angling within the plate hole, facilitating fracture reduction and dynamic compression. It is frequently used as a lag screw to generate interfragmentary compression, a critical technique for primary bone healing.

Engineered for Precision and Stability

Our commitment to quality ensures that every 3.5mm cortex screw delivers consistent intraoperative performance. The design incorporates several key features to assist surgeons:

• Asymmetrical Thread Profile: The thread design is optimized to maximize surface area contact within the dense cortical bone. This deep thread profile ensures superior pull-out resistance, which is essential for maintaining reduction during the healing process.
• Self-Tapping Tip: The screw features sharp, precision-ground cutting flutes at the tip. This self-tapping capability allows the screw to cut its own thread path, eliminating the need for a separate tapping step in most bone qualities, thereby reducing surgical time.
• Spherical Head Design: The underside of the head is spherical, allowing the screw to sit flush within the holes of Dynamic Compression Plates (DCP) or Locking Compression Plates (LCP) when used in a non-locking function. This design permits screw angulation to avoid fracture lines or other implants.
• Reliable Drive Mechanism: Available with a standard 2.5mm Hexagonal recess or a Star (Torx) drive. The deep recess ensures excellent torque transmission and minimizes the risk of the screwdriver slipping (cam-out) during insertion and removal.
• Material Excellence: Manufactured from medical-grade Titanium Alloy (Ti-6Al-4V) for high strength and biocompatibility, or implant-grade Stainless Steel (316L) for rigid fixation.

Clinical Applications and Indications

The 3.5mm Cortical Screw is indicated for the fixation of fractures, osteotomies, and non-unions in small bones. It is the versatile workhorse of the operating room, commonly used in:

• Ankle Fractures: Fixation of the distal fibula (lateral malleolus) and medial malleolus.
• Upper Extremity: Fractures of the distal humerus, olecranon, and shaft of the radius and ulna.
• Clavicle and Scapula: Stabilization of collarbone fractures and shoulder girdle injuries.
• Pelvic Surgery: Specific applications in acetabular reconstruction.
• Lag Screw Technique: Used independently or through a plate to compress fracture fragments together.
