Clavicle fractures present very different fixation challenges depending on fracture location, fragment size, bone quality and the involvement of the coracoclavicular and acromioclavicular structures. The Medartis APTUS Clavicle System 2.8 approaches these challenges with a comprehensive portfolio of anatomically designed plates for midshaft, lateral and lateral-to-midshaft clavicle fixation.

Rather than relying on a single plate concept for different fracture patterns, the system provides dedicated superior, anterior and lateral fixation options, including solutions for complex and revision cases. Plate contours are developed using CT data, with low-profile designs, rounded edges and fracture-specific geometries intended to reduce the need for intraoperative plate bending.

APTUS Clavicle Hook Plate 2.8 — Rethinking the Hook Plate

The APTUS Clavicle Hook Plate 2.8 introduces an anatomy-first approach to hook plate fixation.

Traditional hook plate positioning can require compromise between plate position on the clavicle and placement of the hook beneath the acromion. The new Medartis concept reconsiders the relationship between the plate and hook to provide greater flexibility in positioning according to individual anatomy.

With multiple hook configurations, the surgeon can select a construct that better accommodates the anatomical situation while allowing a very lateral plate position. The concept is designed to help avoid unnecessary intrusion into the AC joint capsule and to preserve the AC joint as much as possible.

The result is not simply another hook plate, but a system designed around anatomical positioning and surgical flexibility.

Superior-Anterior Fixation — Stability in Two Planes

For selected fracture configurations, the clavicle portfolio incorporates superior-anterior plate concepts, creating fixation across two planes rather than relying exclusively on a traditional single-plane construct.

This orthogonal approach provides additional possibilities for fragment capture and construct stability, particularly where fracture morphology makes conventional screw positioning difficult.

The same principle can be seen in the APTUS Superior Lateral Plate, where dedicated anterior-to-posterior screw options complement superior fixation. Medartis biomechanical research on unstable lateral clavicle fractures demonstrated significantly higher ultimate load to failure when additional AP locking screws were incorporated compared with the plate-only construct.

More Options for Complex and Revision Cases

Complex clavicle reconstruction may require fixation extending well beyond the immediate fracture or non-union zone. Long superior-lateral plate configurations provide multiple screw-positioning possibilities on both sides of the reconstruction, offering another option for difficult fracture patterns, malunions, non-unions and revision surgery.

Across the portfolio, the objective is to provide the surgeon with the appropriate plate according to the indication, fracture location and required fixation strategy rather than forcing different clinical situations into one plate design.

Designed as a Complete Clavicle Platform

APTUS Clavicle System 2.8 combines its plate portfolio with Medartis fixation technologies:

• TriLock multidirectional locking allows screws to pivot freely by ±15° in all directions, providing flexibility in screw trajectory and fragment fixation.

• TriLock PLUS combines angular-stable locking and compression within the same screw hole.

• 2.8 mm screw platform provides a uniform screw diameter across the system.

• HexaDrive self-holding screw technology facilitates screw pick-up and handling.

• Preangled screw trajectories and drill guide blocks support controlled screw positioning in anatomically demanding areas.

• CC suture fixation options are integrated into selected superior lateral plates when additional coracoclavicular stabilization is required.

From straightforward fractures to demanding reconstruction

The expanded APTUS Clavicle portfolio reflects a broader approach to clavicle fixation: anatomy-specific plates, multidirectional fixation and dedicated solutions for different fracture configurations.

From midshaft and distal clavicle fractures to hook plate indications, complex patterns and revision surgery, the system provides surgeons with more options to match the construct to the anatomy — rather than adapting the anatomy to the implant.
