Synthes 201.618 2.4mm Cortex Screw Self-Tapping 18mm

Synthes 2.4mm Cortex Screw | Self-Tapping | Cruciform Recess | 18mm | 201.618

The Synthes 201.618 is a high-precision internal fixation implant engineered for stable anchorage in dense cortical bone. As a 2.4mm diameter screw with an 18mm length, it is a foundational component of the Synthes 2.4mm Small Fragment and Hand Systems. This screw is specifically designed for procedures where anatomical space is limited, providing reliable shear strength for stabilizing fractures in the metacarpals, phalanges, or distal radius.

Constructed from 316L Surgical Stainless Steel, the 201.618 features a self-tapping distal tip with precision-machined cutting flutes. This design allows the screw to create its own thread path as it is advanced, eliminating the need for a separate tapping step and providing the surgeon with superior tactile feedback during final seating.

Technical & Clinical Advantages

• Self-Tapping Efficiency: The integrated cutting flutes at the screw tip allow for direct insertion into a pre-drilled 1.8mm pilot hole. This reduces operative time and minimizes the number of instrument passes, which is critical in delicate small-bone reconstructions.

• Cruciform Drive Engagement: The 3.5mm head features a cruciform recess, providing a self-centering interface with the screwdriver. This ensures secure engagement and precise torque transmission, reducing the risk of "cam-out" during insertion into dense cortical bone.

• Low-Profile Head Design: The small 3.5mm head diameter is designed to sit flush within Synthes 2.4mm plates or directly against the bone surface. This minimizes hardware palpability and prevents irritation of overlying tendons and soft tissues, a common concern in hand and foot surgery.

• Optimal Cortical Purchase: The 1.0mm thread pitch and 1.7mm core are engineered to maximize the "bite" in the hard outer shell of the bone. At an 18mm length, it is ideal for bicortical fixation in the metacarpals or metatarsals.

• 316L Stainless Steel Biocompatibility: Forged from vacuum-melted surgical steel, the 201.618 offers high fatigue resistance and biological inertness, facilitating early functional mobilization in 2026.

Applications

• Hand & Wrist Surgery: Fixation of metacarpal and phalangeal fractures or small bone osteotomies.

• Foot & Ankle Surgery: Stabilization of metatarsal fractures and small-fragment midfoot fusions.

• Small Fragment Trauma: Supplemental fixation for fractures of the distal radius or fibula.

• Pediatric Orthopedics: Precise fixation in pediatric long bone fractures where larger hardware is anatomically contraindicated.
