The Clavicle Hook Locking Plate is a unique, specialized implant designed for the surgical management of severe Acromioclavicular (AC) joint dislocations (Tossy III-VI/Rockwood III-VI) and specific distal clavicle fractures. The defining feature is the anatomically shaped hook extending from the plate, which is positioned beneath the acromion process. This hook provides the mechanical leverage necessary to temporarily reduce and hold the displaced distal clavicle and shoulder joint in place. Constructed from medical-grade Titanium Alloy (Ti6Al4V ELI), the plate features Locking Technology along the clavicular shaft, ensuring maximum stability against the pull of the trapezius muscle. The TOOLMED Hook Plate is essential for restoring the anatomical relationship between the clavicle and the acromion, facilitating ligament healing and preventing chronic shoulder instability.

Product Description
The specialized hook engages the undersurface of the acromion, allowing the surgeon to forcefully push the clavicle down and hold the AC joint in its reduced anatomical position.
The clavicular portion utilizes locking screw technology to provide rigid fixation along the distal clavicle, preventing implant migration and ensuring stability in the thin cortical bone.
The plate shaft is contoured and streamlined to minimize palpable irritation along the subcutaneous clavicle, enhancing patient comfort during the recovery phase.
Made from Ti6Al4V ELI, ensuring high strength, non-ferromagnetic properties (MRI compatibility), and excellent biological acceptance in the soft tissue environment.
Primary indication for grade III and higher Acromioclavicular joint dislocations where surgical reduction and temporary mechanical stabilization are required.
Used in specific distal clavicle fractures (Neer Type II or V) where strong ligament reconstruction or plate fixation alone may not be sufficient to maintain reduction.
Indicated for chronic AC joint instability or symptomatic non-union of the distal clavicle associated with vertical displacement.

The Clavicle Hook Locking Plate is a titanium plate with a specialized "hook" on one end. Imagine the hook fitting right under the bony shelf of your shoulder (the acromion). This device is unique because it mechanically pulls the collarbone down and holds the shoulder joint in place, which is necessary when the strong ligaments holding the joint together are completely torn.
This plate is used for serious shoulder separations (AC joint dislocations). When the ligaments are ruptured, the collarbone pops up. The Hook Plate is surgically implanted to force the bone back into place and act as a temporary synthetic ligament, allowing the body's natural ligaments time to heal or scar down in the correct, reduced position.
The primary advantage is immediate, rigid vertical stability. Unlike simple plates or wires, the hook prevents the collarbone from lifting up. The locking screws on the clavicle ensure the plate itself doesn't pull out. This combination provides a powerful hold, which allows the surgeon to reduce the severe dislocation and reliably maintain it during the crucial healing phase.
Biomechanically, the hook plate creates a lever system. The hook is the fulcrum under the acromion, and the plate screwed into the clavicle acts as the load arm. When the screws are tightened, the force pushes the clavicle down and the acromion up, restoring the correct anatomical relationship against the strong pull of the shoulder muscles.
The procedure involves an incision over the shoulder/clavicle. The surgeon reduces the displaced clavicle and slides the hook under the acromion, ensuring the hook is seated correctly. The plate is then secured to the clavicle with locking screws. Often, the hook plate is combined with suture fixation around the ligaments for a belt-and-suspender approach.
The Hook Plate is generally considered a temporary implant and is typically removed after 3 to 6 months once the torn ligaments and bone (if fractured) have fully healed. Removal is necessary because the hook can cause erosion (wearing away) of the bone underneath the acromion if left too long. Early limited motion is started, but overhead lifting is restricted until removal.
The Clavicle Hook Locking Plate is a highly effective, specialized solution for severe AC joint injuries. Its unique hook design and locking stability provide the rigid reduction needed to treat high-grade shoulder dislocations, offering patients a reliable pathway back to a stable shoulder.
Yes, the hook plate is typically removed between 3 and 6 months after the initial surgery. If left longer, the hook can cause bone erosion (osteolysis) under the acromion, leading to pain.
The hook is carefully placed in the sub-acromial space. While it is close to the rotator cuff tendons, specialized surgical techniques are used to ensure the plate is positioned correctly to avoid rubbing or damage.
No. This plate is only used for fractures very close to the AC joint (distal/lateral clavicle) or for AC joint dislocations. Mid-shaft clavicle breaks use a different, straight plating system.
The removal is a relatively simple outpatient surgery. A small incision is made, the screws are removed, and the hook plate is slid out from under the acromion. Recovery is quick, often just a few weeks.
Both standard cortical screws and locking screws (3.5mm) are typically used. The locking screws are critical for holding the plate to the thin bone of the distal clavicle.
