Operation Definition
Taking out or off a device from a body part
Procedure Overview
Removal procedures take out a device that was previously placed in or on a lower bone - hardware such as plates, screws, rods, pins, external fixator components, or spacers used in the pelvis, femur, tibia, fibula, patella, or foot bones. These devices are typically inserted to stabilize a fracture, hold a bone graft, or support a joint during healing, and removal happens once that purpose has been served or if the device is causing a problem.
Reasons for removal vary widely. Hardware may simply be scheduled for extraction after a fracture has healed, especially in children whose growing bones can be irritated by permanent implants. In other cases the device is removed because it has become infected, has loosened, is causing pain from irritating overlying soft tissue, or is interfering with a later procedure such as a joint replacement.
Anatomy & Axis Detail
Patella, Left
The left patella is the sesamoid bone anterior to the knee, embedded in the quadriceps tendon, and Removal here refers to taking out a previously placed device rather than excising bone or tissue. Patellar fractures and tracking disorders are frequently stabilized with tension-band wires, cannulated screws, or Kirschner wires, and these implants are removed once healing is confirmed or if they cause anterior knee pain, hardware prominence under the thin overlying skin, or irritation during kneeling. Because the patella sits directly beneath the skin with minimal soft-tissue coverage, hardware migration or symptomatic prominence is common, making elective removal a frequent outpatient procedure. Documentation should specify the type of device extracted and confirm no residual bone fragment or foreign material remains within the joint space.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Device: Internal Fixation Device
Internal fixation device is the general value for hardware such as plates, screws, or rods placed within the body to stabilize bone or joint, used when a more specific configuration is not indicated. It stands in contrast to the named subtypes - Rigid Plate, Intramedullary, Sustained Compression, and Intramedullary Limb Lengthening - which specify how the hardware achieves stabilization.
Coding & Documentation
Coders assign Removal when documentation confirms a device is being taken out and not replaced with another device during the same operative episode - if a new device goes in at the same site, the procedure is Change or a combination of Removal and another root operation such as Insertion, not Removal alone. The device type and the specific bone it was removed from both need to be identifiable from the operative note. A common error is coding Removal for hardware that is only being adjusted or repositioned rather than fully extracted, or overlooking that the removal of a device is bundled into a broader procedure when substantial additional work, like bone repair, is performed at the same site.
