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

Lower Femur, Left

The left lower femur, comprising the distal condylar and metaphyseal region above the knee, often retains plates or intramedullary devices placed for supracondylar femoral fractures or distal reconstructive procedures. Removal describes extracting this previously implanted hardware, typically indicated after fracture union, when the implant irritates surrounding soft tissue near the knee, or when infection mandates its removal. Because this area sits directly adjacent to the knee joint, popliteal neurovascular structures, and the distal quadriceps and patellar tendon attachments, extraction requires precise surgical technique to protect these structures while accessing the hardware. Documentation should specify laterality and identify the device taken out, keeping the procedure distinct from any bone resection or joint-related intervention performed in the same operative episode, which would be captured under a separate root operation.

Approach: External

External approach applies to procedures performed directly on the skin or mucous membrane, or on an accessible body surface, without any instrumentation passing through a puncture or orifice. It covers things like manual reduction of a fracture or excision of a skin lesion. It differs from Via Natural or Artificial Opening in that no internal passage is entered at all, only the exposed surface.

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.

Commonly Confused With

RevisionRevision is the most common point of confusion, since both involve existing hardware; Revision applies when a malfunctioning or displaced device is corrected or adjusted in place rather than taken out entirely.
ChangeChange is distinct because it captures removing a device and inserting a similar one through the same access site in one continuous procedure, most often for external fixation pins, rather than a permanent extraction.
ExtirpationExtirpation is unrelated in intent but sometimes confused when hardware fragments or broken screw pieces are retrieved rather than an intact device.
