CPT® Code 27792

The procedure described by CPT® Code 27792 pertains to the open treatment of a fracture located at the distal fibula, specifically the lateral malleolus, which is the bony prominence on the outer side of the ankle. This area is crucial for ankle stability as it articulates with the tibia at the fibular notch. A fracture in this region can lead to instability in the ankle syndesmosis, a complex structure formed by ligaments including the anterior tibiofibular ligament, interosseous ligament, and posterior fibular ligament. The surgical approach involves making a lateral incision directly over the fracture site, ensuring that the branches of the superficial peroneal and sural nerves are carefully isolated and protected during the procedure. Once the fracture site is adequately exposed and any debris is removed, the fracture is reduced, meaning the bone fragments are realigned. If necessary, internal fixation is applied, typically using a plate and screw device, to stabilize the fracture. After confirming the stability of the ankle syndesmosis, the surgical site is irrigated to prevent infection, and the incisions are subsequently closed to promote healing.
