The Acutrak Advantage

With its introduction in 1994, Acutrak Headless Compression Screw technology revolutionized the way surgeons treat fractures, fusions, and osteotomies. Acutrak 2® introduced the next generation in fully threaded headless fixation, with larger guide wires, larger hex drivers, and a tapered end. The Acutrak 2 System is routinely used in a number of lower-extremity fracture fixations, including those featured below. Explore the Acutrak Advantage.

Features

  • Continuously Variable Thread Pitch

    The Acutrak fully threaded continuously variable thread pitch screw design provides greater compression and a larger window of compression as compared to partially threaded Herbert style screw designs.1 In addition, this feature allows a fracture or osteotomy site to lie almost anywhere along the length of the screw.

  • A Family of Options

    Available in six different families for a total of 68 different screws, addressing applications throughout the upper and lower extremities.

  • Fully Threaded

    Biomechanical studies have shown that fully threaded screws better handle the cyclic loading that may occur during healing. The Acutrak Headless Compression Screw technology has shown greater push-out strength, greater resistance to cyclic loading, and greater resistance to torsional loading when compared to differential pitch screw technology.1

  • A Heritage of Healing

    Over 1.7 million Acutrak family screws implanted since 1994, supported by more than 100 clinical and biomechanical publications.

Videos

This animated overview of the Acutrak 2 Headless Compression Screw System illustrates how the system is designed to treat fractures, fusions, and osteotomies of the upper and lower extremities.

The Acutrak and Acutrak 2 screws have revolutionized headless fixation with a uniquely patented thread pitch that varies continuously from tip to tail. Each thread engages bones faster than its trailing thread, generating gradual compression along the entire length of the screw.
