Successive complications after anterior cervical fixation: p
Pharyngoesophageal diverticulum is an uncommon complication after anterior cervical discectomy and fusion surgery.

The patient was a 48-year-old woman with two previous cervical surgeries with fixation of C4-C5 and C5-C6, the last one in 2003. Two years after surgery, she presented with arthralgia, arthritis, chills, and fluctuating rash. In 2007, she presented with dysphagia, halitosis, and sputum production. She was diagnosed with a pharyngoesophageal diverticulum with a fistula to C6 vertebra and secondary spondylitis. She was taken for open surgery with removal of screws and plates, cricopharyngeal myotomy, and esophageal repair. Streptococcus milleri grew in tissue and osteosynthetic material. She received 4 months of amoxicillin and probenecid and had a complete recovery. Since 1991, 19 similar cases have been reported with one fatality. To our knowledge, this is the first reported case of diverticulum complicated with fistula and secondary spondylitis.
