Hi & Welcome. Based on the history you seem to have developed recurrent vertebral osteomyelitis of C6 (6th vertebra in the neck). The selection of antibiotic in such cases is generally determined by culture and sensitivity test results. However, Vancomycin or Daptomycin (Cubicin) are the standard first line antibiotics used to treat such infection. Other alternate effective antibiotics may include Doxycyline, Clindamycin, Rifampicin or Linezolid. The antibiotic therapy should be given for 4- 8 weeks depending upon the extent of the infection. Surgical debridement may become necessary if there is spinal instability, significant deformity, and/or neurologic deficit. Infections of the spine like C6 are extremely destructive and can lead to catastrophic neurologic deficits & paralysis (paraplegia) and death if not properly treated. Hope these answer your queries. Wishing you best of your health.
