Overview

The Acumed Acutrak 2 Headless Compression Screw System is the latest evolution in fully threaded headless screw fixation, with intuitive instrumentation designed to simplify the surgical technique. The Acutrak 2 System may help minimize drill depth sensitivity and offers 68 unique screw size options to fit a wide variety of applications throughout the body. The Acutrak 2 Headless Compression Screw System includes the Acutrak 2 Micro, Acutrak 2 Mini, Acutrak 2 Standard, Acutrak 2 – 4.7, Acutrak 2 – 5.5, Acutrak 2 – 7.5.

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 1.5 million Acutrak family screws implanted since 1994, supported by more than 100 clinical studies.

Acutrak 2 – 7.5

The Acutrak 2 – 7.5 is part of the latest evolution in fully-threaded headless screw fixation. With instrumentation designed to simplify the surgical technique, the Acutrak 2 – 7.5 is composed of 17 unique screw size options to fit a wide variety of applications throughout the body. Indications for the Acutrak 2 – 7.5 include: ankle arthrodesis, triple arthrodesis, talonavicular fusion, calcaneal osteotomy, subtalar fusion, TMT fusion, calcaneocuboid fusion, hindfoot arthrodesis, greater tuberosity fractures, tibial plateau fractures, and femoral condyle fractures. The Acutrak 2 – 7.5 is available in sizes from 40 mm to 120 mm and is inserted using a 4.0 mm hex driver over a .094″ guide wire.

Acutrak 2 – 5.5

The Acutrak 2 – 5.5 is part of the latest evolution in fully-threaded headless screw fixation. With instrumentation designed to simplify the surgical technique, the Acutrak 2 – 5.5 is composed of 8 unique screw size options to fit a wide variety of applications throughout the body. Indications for the Acutrak 2 – 5.5 include: Jones fractures, distal radius fractures, talus fractures, malleolar fractures, midfoot fusions, MTP fusions, greater tuberosity fractures, carpal fusions, radial styloid fractures, MCP fusions, capitellum fractures, tarsal fractures, midfoot fusions, OCD repair, and osteotomies. The Acutrak 2 – 5.5 screws are available in lengths up to 60 mm and inserted with a 3.0 mm hex driver over a .062″ guide wire.

Acutrak 2 – 4.7

The Acutrak 2 – 4.7 is part of the latest evolution in fully-threaded headless screw fixation. With instrumentation designed to simplify the surgical technique, the Acutrak 2 – 4.7 is composed of 10 unique screw size options to fit a wide variety of applications throughout the body. Indications for the Acutrak 2 – 4.7 include: Jones fractures, distal radius fractures, talus fractures, malleolar fractures, midfoot fusions, MTP fusions, greater tuberosity fractures, scaphoid fractures, and nonunions, carpal fusions, radial styloid fractures, MCP fusions, capitellum fractures, tarsal fractures, midfoot fusions, OCD repair, and osteotomies. The Acutrak 2 – 4.7 are available in lengths up to 50 mm, are inserted with a 3.0 mm hex over a .062″ guide wire and are color-coded for easy identification in the surgery room.

Acutrak 2 Standard

The Acutrak 2 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 2 Standard is extremely versatile, with a variable thread pitch and fully-threaded length that can provide excellent compression for the patient. The Acutrak 2 is indicated for: scaphoid fractures and nonunions, capitellum fractures, navicular fractures, bunionectomies, 5th metatarsal fractures, carpal fusions, and MCP fusions. Acutrak 2 Standard screws are inserted with a 2.5 mm hex driver over a .054″ guide wire.

Acutrak 2 Mini

The Acumed Acutrak 2 Mini incorporates the same design principles as the rest of the Acutrak 2 family of screws, with a smaller diameter and shorter lengths. The Acutrak 2 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 2 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 2 Mini screws are available in lengths up to 30 mm, are inserted with a 2.0 mm hex over a .045″ guide wire and are color-coded for easy identification in the surgery room.

Acutrak 2 Micro

The Acutrak 2 Micro incorporates the same design principles as the rest of the Acutrak 2 family of screws. The Acutrak 2 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 2 Micro include: radial head fractures, phalangeal fractures, carpal fractures, metacarpal head fractures, proximal pole scaphoid fractures. Acutrak 2 Micro screws are available in lengths up to 30 mm, are inserted with a 1.5 mm hex over a .035″ guide wire and are color-coded for easy identification in the surgery room.
