Operation Definition
Correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device
Procedure Overview
Revision procedures correct a malfunctioning device already implanted in a lower joint, or reposition a device that has shifted out of place, without necessarily removing and replacing the whole implant. Examples include tightening a loosened hip component, adjusting a worn knee liner, or repositioning a dislocated joint implant back into alignment. The reason for surgery is a problem with hardware from an earlier operation rather than new injury to native tissue.
These procedures are often needed years after an initial joint replacement, as components can loosen, wear, or shift with normal use. Surgeons aim to fix the specific mechanical problem while preserving as much of the existing implant and surrounding bone as possible, since more extensive revisions carry greater surgical risk and longer recovery.
Anatomy & Axis Detail
Toe Phalangeal Joint, Right
Revision of a right toe phalangeal joint pertains to the small interphalangeal articulations of the toes, frequently the site of earlier surgery for hammertoe correction, such as an implant or fixation wire used to maintain toe alignment after arthroplasty or fusion. When a pin migrates, an implant subluxes, or a fusion fails to consolidate, the toe can drift back into a deformed or painful position, and revision surgery corrects this by repositioning, exchanging, or removing the previously placed hardware. Because toe phalangeal joints are numerous and anatomically small, precise identification of the affected toe and joint level, along with clear specification of whether the correction involves adjustment, replacement, or removal, is important for accurate documentation.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
Device: Spacer
In Medical and Surgical procedures, a Spacer is a temporary, non-articulating device left in a joint or space after a component is removed, most often an antibiotic-impregnated cement block placed during a staged joint revision to control infection while preserving space and alignment. It is not intended to move like a real joint. It differs from an Articulating Spacer, which is shaped to permit some motion during the interim period, and from a permanent Synthetic Substitute.
Coding & Documentation
Documentation needs to identify that an existing device was the target of correction, whether through repositioning, adjustment, or partial component exchange, and that the fix did not amount to a full swap of the entire prosthesis. Notes describing loosening, malposition, or component wear typically support Revision. A common error arises when a full component exchange occurs during a documented revision surgery; if the entire device is replaced, the correct root operation is Replacement, even though the surgeon may call it revision arthroplasty.
