Cannulated Headless Compression Screw with Double-Ended Threads

Kangli Orthopaedics manufactures this titanium alloy cannulated headless compression screw for orthopedic fixation procedures involving the foot and ankle. It features threaded sections at both ends, a smooth central shaft, and a central passage for guided insertion. The headless design provides a compact screw profile when seated.

Cannulated Design for Guided Insertion

A central cannulation extends along the screw’s longitudinal axis. This passage accommodates a guide wire during insertion and helps maintain the intended trajectory through the implant. The cannulated configuration can be incorporated into established guided screw-placement workflows.

Double-Ended Threads for Compression Fixation

Threaded sections at both ends are separated by a smooth central shaft. The two thread zones are designed to engage separate sides of a fixation interface, allowing the screw to be used for compression fixation across the selected construct.

Headless Profile for Flush Seating

The screw has no enlarged head at either end. When seated, its terminal profile remains close to the surrounding surface, making the headless configuration suitable for fixation where a prominent screw head is not selected.

Pointed and Blunt Ends for Orientation

One threaded end features a pointed terminal tip, while the opposite end has a blunt, slightly rounded or chamfered profile. These contrasting geometries distinguish the leading and trailing ends and assist with orientation during insertion.

Foot and Ankle Fixation Applications

The screw is intended for use in fixation constructs involving the foot and ankle, including:

• Cannulated compression screw fixation in the foot
• Cannulated compression screw fixation in the ankle
• Headless fixation where a flush-ended implant profile is preferred
• Double-ended threaded fixation across a bone interface

Kangli Orthopaedics lists this screw alongside the Beveled-Head Cannulated Buttress Screw System for foot and ankle fixation applications requiring a different head configuration and thread arrangement.
