Various locking options are available within the nail:

Distally, the spiral blade increases surface area and enhances load distribution in the calcaneus
The 6.0 mm locking screws allow a posterior-to-anterior fixation for improved purchase in the calcaneus as well as a calcaneocuboid fusion option
The appropriate endcap provides a fixed-angle construct with the spiral blade and/or the 6.0 mm locking screw
The angulated 5.0 mm locking screw through the talus facilitates the subtalar fusion by additional fixation and provides an optional talar/navicular fusion
Proximally, the placement of the two 5.0 mm locking screws are targeted through the aiming arm, regardless of nail length
The system allows different locking orientations: Medial-to-lateral or lateral-to-medial
The dynamization slot allows optional postoperative compression

The lateral bend of the nail is designed to do the following:

Restore 3° to 5° of valgus positioning to improve patient’s gait
Avoid damage to the lateral plantar artery and nerve
