C1-C2 arthrodesis after spontaneous Propionibacterium acnes spondylodiscitis: Case report and literature analysis

Vertical Subluxation Caused by Infection Around the Odontoid Process: A Case Report

Introduction

There are few reports of cases with vertical subluxation. We report our experience of a vertical subluxation of the atlantoaxial joint caused by infection.

Case Report

A 63-year-old man had a 5-month history of neck pain. He was treated for rheumatoid arthritis by a local doctor. At admission to our hospital, he had neck pain and complained of dysphagia and hoarseness. His white blood cell count and C-reactive protein were 7200/mm3 and 4.86 mg/dL. Cervical X-ray showed atlantoaxial subluxation. Computed tomography showed osteolysis around the odontoid process, including the atlantooccipital and atlantoaxial joints, causing vertical subluxation. Magnetic resonance imaging showed spinal cord and brainstem compression and the presence of fluid. Gadolinium-enhanced magnetic resonance imaging showed enhancement around the odontoid process. We performed occipital-cervical spine fixation and C1 laminectomy. Following surgery, his symptoms completely resolved. Bone fusion was confirmed 6 months after surgery.

Conclusion

If subluxation of the upper cervical spine occurs rapidly, infection should be considered.

Destructive cervical spondylitis due to Cutibacterium acnes with synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome: A case report

Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is a spectrum of heterogeneous diseases commonly recognised by skin and osteoarticular lesions. There have been reports of some surgical cases of the progressive, destructive spondylitis associated with SAPHO syndrome, wherein the destructive spondylitis was considered to have developed due to the progression of spondylitis with SAPHO syndrome as the pathogenic bacteria were not isolated. We herein report a surgical case of destructive cervical spondylitis associated with SAPHO syndrome. A 54-year-old woman with a history of palmoplantar pustulosis suffered severe neck pain for 6 months. Radiography and computeed tomography showed sclerosed and collapsed cervical vertebrae, and the patient was referred to our hospital for further evaluation and management upon suspicion of infection or spondylitis with SAPHO syndrome. For the severe neck pain and progressive destruction of cervical vertebrae, we performed posterior fusion surgery with subsequent anterior fusion. Cutibacterium acnes (C. acnes) was isolated by enrichment culture with thioglycolate broth from both the anterior and the posterior tissue samples. We diagnosed pyogenic spondylitis secondary to C. acnes infection and administered doxycycline for 6 weeks after the first surgery. The neck pain was resolved and cervical fusion was achieved one year postoperatively. C. acnes infection could elicit destructive spondylitis. An enrichment culture should be performed to isolate the pathogenic bacteria in cases of destructive spondylitis with SAPHO syndrome.

Propionibacterium acnes causing non-contiguous, multifocal spondylodiscitis in an immunosuppressed patient

This report describes a case of a spondylodiscitis in an immunocompromised patient with an HIV infection caused by Propionibacterium acnes The patient was admitted to hospital with a sudden loss of motor function and sensation in both of the patient's legs. A biopsy taken during the first debridement operation proved to be negative for Mycobacterium tuberculosis DNA and growth, but was positive for the growth of P. acnes Following a course of antibiotic therapy and the aforementioned debridement, the patient was moved to a specialised clinic for physical therapy. The patient's condition quickly deteriorated, and the patient once again required extensive debridement. Repeated spinal surgery, antibiotics for 12 weeks and subsequent rehabilitation resulted in almost complete recovery of sensorimotor limb function.
