Procedure Overview
Resection in the lower joints means surgically removing an entire joint or joint structure without replacing it with any device. This is less common than joint replacement, typically reserved for severe infection that has destroyed a joint, a tumor requiring removal of the joint surfaces, or a salvage option after a failed implant cannot be replaced right away. A well-known example is resection arthroplasty of the hip, sometimes called a Girdlestone procedure, where the femoral head is removed and the space fills with scar tissue.
Because no artificial joint is inserted, patients typically have a shortened limb and altered mechanics, and mobility aids or later reconstruction may follow. This trade-off is usually accepted specifically to clear infection or malignant tissue threatening the limb.
Anatomy & Axis Detail
Sacroiliac Joint, Right
The right sacroiliac joint is the small, largely immobile articulation between the sacrum and the ilium, stabilized by dense interosseous and posterior ligaments rather than a mobile capsule. Resection here removes all or a substantial portion of the articular surfaces, most often for severe degenerative sacroiliitis, infection unresponsive to debridement, chronic instability, or a tumor involving the joint. Because the joint sits deep within the pelvis adjacent to the sacral nerve roots, iliac vessels, and sciatic notch, surgeons frequently pair excision with instrumented fusion in the same operative episode, though the fusion hardware itself is coded separately from the resection. Documentation should clarify whether the procedure removed cartilage and subchondral bone alone or extended into adjacent sacral or iliac bone, since that distinction affects whether the correct root operation is truly resection rather than a more limited excision.
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.
Coding & Documentation
A coder should look for documentation that the joint or a defined structure was entirely removed and nothing was implanted in its place; if a spacer or prosthesis went in during the same operation, the case likely calls for Replacement or a combination of codes instead of Resection alone. Infection control, pathology reports for malignancy, and prior failed hardware are common clinical justifications. The most frequent error is coding Resection when an antibiotic cement spacer was actually placed, since a spacer typically reclassifies the procedure as Replacement.
