CPT® Code 28576

The procedure described by CPT® Code 28576 refers to the percutaneous skeletal fixation of a dislocated talotarsal joint, which is a critical intervention for restoring proper alignment and stability to the joint. The talotarsal joint, also known as the subtalar joint, is located between the talus and the tarsal bones of the foot. Dislocation of this joint can result from trauma or injury, leading to significant pain, instability, and impaired function of the foot. The procedure involves making a small incision over the dislocated joint to allow for direct access to the affected area. Through this incision, the dislocated tarsal bones are carefully manipulated back into their correct anatomical position, a process known as reduction. To ensure that the bones are properly aligned, radiographs, or X-rays, are taken before and after the manipulation. Following the reduction, additional small incisions are made at the sites where pins or Kirschner wires will be inserted. A specialized drill is used to create a corticotomy, which is a small opening in the bone, facilitating the placement of these fixation devices. The pins or wires are then advanced through the talus and into the tarsal bone, effectively stabilizing the joint and preventing further dislocation. After the fixation devices are in place, another set of radiographs is performed to confirm that the anatomical reduction has been successfully achieved. This procedure is essential for restoring function and alleviating pain in patients with talotarsal joint dislocations.
