Materials
01 — Design features
Cannulation, thread and pitch, reconsidered
Wider cannulation
Accommodates thicker, more rigid guidewires for precise screw placement along the desired axis.
More threads for stronger fixation
Additional threads near the head ensure a stronger hold in cortical bone.
Blunt thread and tapered tip
Facilitates smooth insertion while minimizing chances of graft laceration, and enhances bone graft purchase for optimal stability.
Variable pitch
Enables faster insertion and effectively pulls the graft into place, generating higher torque as each thread carves a new path for secure fixation.
