An unusual cause of lumbar discitis.
STUDY DESIGN: Case report. OBJECTIVE: To identify an unusual cause of lumbar discitis. SUMMARY OF BACKGROUND DATA: Discitis resulting from a foreign body has not been reported in the English-language literature. METHOD: A case report is reviewed identifying the presence of this foreign object (titanium), erroneously implanted into the disc space at L5-S1. Imaging studies identify the location and surrounding reaction. RESULTS: The surgical exploration of this disc revealed an inflammatory response surrounding the disc with degeneration within the disc space. CONCLUSION: If this gynecologic procedure is performed using bone anchors, care must be take to ensure that the sacrum is identified before insertion.
