Delayed surgical site infection 2 years after cervical disk arthroplasty. Case report and literature review.

Anterior cervical discectomy has a low non-mechanical complication rate. In our literature review, we found 7 cases of delayed surgical site infection. We report a case of cervical prevertebral abscess due to Propionibacterium acnes 2 years after discectomy and arthroplasty, with a beta-2-transferrin false positive test as a complementary highlighted finding. We discuss the diagnosis and etiology of this rare delayed infectious complication.
