Cervical spine epidural abscess: a single center analytical comparison to the literature.

STUDY DESIGN

Retrospective review of patient charts.

OBJECTIVES

Cervical spine epidural abscess (CSEA) is uncommon. In this study, characteristics of CSEA patients are described through an institutional analysis and literature review.

SETTING

University-affiliated city hospital.

METHODS

The electronic medical record was searched from 01/2001 to 01/2012. Data on presentation, comorbidities, diagnostic modalities, pathogens, treatments, and neurological recovery were collected.

RESULTS

Sixteen patients were identified with a mean age of 57.9 years (33-83). Nine were females. Common symptoms were neck/back pain (62.5%), neurological deficits (62.5%), and fever (31.3%). Comorbidities included cardiovascular disease (56.3%), renal disease (37.5%), and diabetes mellitus (37.5%). Lower levels were more likely afflicted (C5-C7). Microorganisms were commonly Staphylococcus and Streptococcus (68.8%). Eight (50.0%) received surgery (anterior [87.5%] and posterior [12.5%] cervical fusion and corpectomy [37.5%]) plus antibiotics and 8 (50.0%) were treated with antibiotics only. Patients with less comorbidities were more likely to receive surgery; more comorbidities were was associated with a poor prognosis. Eight patients (50%) made had full neurological recovery, 2 (12.5%) with had minimal recovery, 2 deaths died, and the remaining (25%) 1 was were sent to a skilled facility and 1or lost to follow-up.

CONCLUSIONS

Cervical SEA can be problematic. The vast majority do not present classically and treatment does vary. It occurs more frequently in the lower cervical levels. Though antibiotics alone may suffice, surgery is frequently employed and a multitude of techniques are at the utility of the spine surgeon. Cardiovascular comorbidities are associated with a poorer outcome. In order to improve prognosis, management considerations should include both patient factors and multidisciplinary efforts.
