“…In humans that required revisional craniocervical junction surgeries, 13 of 55 (23.6%) patients required revisional surgery to remove an infected implant [ 13 ]. The use of sublaminal wires, the inclusion of the occiput in the fusion, and transoral decompression preceding posterior fixation were significantly associated with the development of an implant infection requiring surgical removal [ 13 ]. The duration between the first surgery and the revisional surgery was variable and ranged from one year to 19 years.…”

An 11-year-old male neutered Yorkshire Terrier was presented with a cervical mass that developed a draining tract. Aside from the dysphagia reported by the owner, his neurologic exam was normal. Three years prior, the patient was diagnosed with an atlantoaxial subluxation that was ventrally stabilized with polymethylmethacrylate (PMMA) and self-tapping titanium screws. There were no postoperative complications until presenting with the cervical mass and dysphagia. Computerized tomography (CT) of the cervical spine confirmed caudal migration of the PMMA and screws with an abscess surrounding the implant. A surgical explant of the PMMA and screws was performed without complication. The atlantoaxial joint remained normally aligned on postoperative radiographs. Cultures of the implant grew Streptococcus bovis. He was treated with cephalexin (22 mg/kg PO BID) for 30 days. At the time of his one-month recheck, he was swallowing normally with no neurologic deficits. He remains normal at the time of this report (17 months later). This case reports a successful explant of a chronic atlantoaxial implant infection.
