## Introduction
Calcaneal (heel) fractures are notorious for high rates of post-operative wound complications. The skin covering the lateral aspect of the heel is extremely thin and has a delicate blood supply. Traditional bulky plates often lead to “skin sloughing” or deep infection.
## The Low-Profile Solution
Modern calcaneal plates are designed to be as thin as possible (often less than 1.5mm) while maintaining high mechanical strength through locking technology.
* **Titanium Advantage:** Titanium allows for thinner plates that are stronger than thicker stainless steel versions.
* **Rounded Edges:** Smooth, tapered plate borders prevent the hardware from “rubbing” through the skin.
* **Anatomic Contouring:** Plates are pre-shaped to the complex lateral wall of the calcaneus, reducing the need for intraoperative adjustment that can further damage soft tissues.
## Biomechanics of Locking Fixation
Because the calcaneus is primarily cancellous bone, traditional screws often fail. Locking screws provide a fixed-angle construct that holds the “Sander鈥檚 type” articular fragments securely, preventing the joint from collapsing back into a flat-foot deformity.
## Clinical Tips for Success
* **Wait for the Skin:** Never rush calcaneal surgery. Wait until the swelling has subsided (the “wrinkle test”).
* **No-Touch Technique:** Avoid excessive retraction of the lateral skin flap.
* **Small Screws:** Use 2.7mm or 3.5mm screws to keep the hardware footprint small.
## Conclusion
By utilizing Ortholyx low-profile calcaneal locking plates, surgeons can achieve rigid fixation while significantly lowering the risk of devastating soft tissue complications in the foot.
