When severe arthritis, instability, or deformity cannot be controlled with a nonsurgical approach, a surgeon may choose to fuse one or all of the three joints in the back of the foot (the talonavicular, subtalar, and calcaneocuboid). Acutrak screw technology may be advantageous for these fusions because a headless compression screw is designed to minimize soft tissue irritation.

Compression: Gained and Retained

Maintains the highest amount of retained compression after cyclic loading compared to AO and Herbert screws in cadaveric and synthetic bone material1

Acutrak technology has a wider window of compression, which is less sensitive to stripping the bone and more flexible in its placement for reaching a maximum amount of compression.

Better Resistance to Rotation

A biomechanical study regarding subtalar fusion found that using two Acutrak 2—7.5 mm screws offered better resistance to rotation in subtalar fusions than two conventional lag screws2

Higher Torsional Stiffness

The two Acutrak 2—7.5 mm screws showed higher torsional stiffness in a biomechanical test compared to that previously reported with two conventional lag screws2


Triple Arthrodesis Cadaveric Lab with Nicholas Abidi, MD
A triple arthodesis fusing the talonavicular, subtalar, and calcaneocuboid joints is performed using Large Acutrak 2 4.7 and 7.5 screws. The rationale for the use of the screws, radiographic evidence, and surgical steps are provided.

Acutrak 2 Headless Compression Screw System – 4.7 mm & 7.5 mm


The Acumed Acutrak 2 - 4.7 and 7.5 are part of the latest evolution in fully-threaded headless screw fixation. With instrumentation designed to simplify the surgical technique, the Acutrak 2 screws are composed of unique size options to fit a wide variety of applications throughout the body. Besides Triple Arthrodesis fractures, this includes:
