T84: Complications of internal orthopaedic prosthetic devices, implants and grafts

T84.2: Mechanical complication of internal fixation device of other bones

Mechanical complications of internal fixation devices of other bones refer to problems that occur after an internal fixation device is surgically placed inside a bone to stabilize or realign it. These devices are often used in the treatment of fractures or orthopedic conditions that damage bone structure. Complications can arise due to movements of the device itself, unsuccessful integration into the bone, or due to forces exerted on the affected area. Patients may experience symptoms such as pain at the site of fixation, difficulty in normal movement, joint stiffness, or swelling. In more serious cases, this may result in a failure of the fracture to heal properly, a condition known as nonunion. It is not uncommon for these complications to necessitate a revision surgery to either adjust or replace the problematic device.
