CPT® Code 27832

Open treatment of proximal tibiofibular joint dislocation, includes internal fixation, when performed, or with excision of proximal fibula

The procedure described by CPT® Code 27832 refers to the open treatment of a dislocation at the proximal tibiofibular joint. This joint is a synovial joint located at the back and side of the knee, specifically between the lateral condyle of the tibia and the head of the fibula. Synovial joints, such as the proximal tibiofibular joint, are characterized by their structure, which includes a joint cavity filled with synovial fluid, and are lined with a synovial membrane. They are also supported by ligaments and a joint capsule that provide stability. The open treatment involves making a lateral incision over the joint to access the area directly. During the procedure, the surgeon carefully identifies and dissects the overlying ligaments and tendons, ensuring the protection of the peroneal nerve, which runs close to the joint. The dislocated joint is then exposed, and the dislocation is corrected using specialized instruments. Depending on the severity of the dislocation and the condition of the surrounding structures, internal fixation may be applied to stabilize the joint, or the proximal fibula may be excised if necessary. This procedure is critical for restoring function and stability to the knee and lower leg following a dislocation injury.
