Overview

Acutrak 3 is the latest innovation in our headless compression screw technology and is comprised of 93 unique screws that include the introduction of a new 2.0mm diameter Nano screw and extensions to the existing lengths of the Micro, Mini, and Standard screws, allowing expansion on the many indications historically treated with the Acutrak 2 system.

Instrumentation

Additionally, Acutrak 3 has redesigned the instrumentation with a focus on ease of use for surgeons: all screws measure from the tail/back of a guide wire, the new screw sizer allows for implant measurements at unique angles, the drivers have a new hexalobe interface, and a parallel guide wire has been added for stability or secondary implants between 2.5 mm – 20 mm in distance.

Key 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 studies.

Acutrak 3 Standard

The Acutrak 3 Standard is designed for the fixation of small bone fractures and joint fusions, where a 3.5 mm – 4.0 mm headed screw or an equivalent-sized headless screw would otherwise be required. The Acutrak 3 Standard is extremely versatile, with a variable thread pitch and fully-threaded length that can provide excellent compression for the patient. The Acutrak 3 is indicated for: scaphoid fractures and non-unions, capitellum fractures, navicular fractures, bunionectomies, 5th metatarsal fractures, carpal fusions, and MCP fusions. Acutrak 3 Standard screws are inserted with a 2.5 mm hex driver over a .054″ guide wire.

Acutrak 3 Mini

The Acutrak 3 Mini incorporates the same design principles as the rest of the Acutrak 3 family of screws, with a smaller diameter and shorter lengths. The Acutrak 3 Mini is designed for the fixation of small bone fractures and joint fusions, where a 3.5 mm – 4.0 mm headed screw or an equivalent-sized headless screw would otherwise be required. Indications for the Acutrak 3 Mini include: scaphoid fractures and nonunions, bunionectomies, radial styloid fractures, radial head fractures, avulsion fractures, carpal fusions, MCP fusions, OCD repair, and Phalangeal fractures. Acutrak 3 Mini screws are available in lengths up to 60 mm, are inserted with a 1.1mm single or double trocar guide wire and color coded corresponding option of bone drill.

Acutrak 3 Micro

Acutrak 3 family of screws. The Acutrak 3 Micro is designed for the fixation of small bones and fracture fragments, where a 2.0 mm – 2.4 mm headed cruciform screw or an equivalent-sized headless screw would otherwise be required. Indications for the Acutrak 3 Micro include: radial head fractures, phalangeal fractures, carpal fractures, metacarpal head fractures, proximal pole scaphoid fractures. Acutrak 3 Micro screws are available in lengths up to 50 mm, are inserted with a 0.9 mm single or double trocar guide wire and color coded, corresponding option of bone drill.

Acutrak 3 Nano

The Acutrak 3 Nano incorporates the same design principles as the rest of the Acutrak 3 family of screws. The Acutrak 3 Nano is designed for the fixation of small bones and fracture fragments. Indications for Acutrak 3 Nano include: radial head fractures, phalangeal fractures, carpal fractures, metacarpal head fractures, scaphoid fractures, and DIP & PIP fusions. Acutrak 3 Nano screws are available in lengths up to 40 mm, are inserted with a 0.7 mm single or double trocar guide wire, and their corresponding, color coded options of bone drills.
