Anatomic Distal Fibula Plate
There are a few different options when deciding how to operatively manage a lateral malleolar fracture. The modality most commonly utilized by orthopaedic surgeons is applying an anatomic distal fibula plate. These plates are often contoured to match the native anatomy of the distal fibula.
After reducing the fracture in the operating room, a single plate is applied to the outer surface of the fibula bone and fixed to the bone using screws. This plate helps maintain anatomic reduction of the fracture to allow the body to heal the bone over time. Although seldom, some patients may experience some irritation from these plates over time necessitating their removal down the road.
Open Reduction Internal Fixation of Distal Fibula
A single plate with multiple screws are commonly utilized for lateral malleolar fractures. Some of the basic principles of fracture fixation are as follows:
- fractures should be reduced to restore anatomic alignments
- fractures should be treated with a fixation method that provides stability
- there must be enough blood supply to allow for the body to heal the injury
- treatment should allow for early and safe mobilization of the injured area
Ankle fractures usually require additional intraoperative tests to determine ankle stability. If deemed unstable, additional screws or the use of a tightrope construct may be required to obtain ankle stability. Patients should discuss this possibility with their surgeon and how it may affect recovery.
The Zimmer Biomet A.L.P.S.® Fibula Plating System offers a distal fibular plate that combines the dense strength of titanium with a low profile manufacturing design to provide maximal stability with minimal irritation to the surrounding soft tissue. There are two distinct plate options within this set for orthopaedic surgeons to choose from:
1.) Anatomic locking plate that is pre-contoured to fit the lateral aspect of the distal fibula
2.) Composite locking plate with a flexible design to allow intra-operating contouring
Together, this set offers a wide variety of options for the surgeon to choose from depending on fracture pattern and patient-specific factors affecting surgical fixation.
