ABSTRACT
Objective:
Spondylodiscitis is still a frequent pathology among neurosurgical services, and its correct treatment involves infectious, neurological and orthopedic goals. The authors describe the protocol and report the diagnostic and therapeutic results after its implementation.
Methods:
A prospective prognostic study (Level I) including patients with primary spondylodiscitis treated in the Neurosurgical Service of Cristo Redentor Hospital from January 2014 to March 2018. Demographic, spine, infectious and treatment-related variables were analyzed. The numerical variables are presented as mean and standard deviation or median and interquartile range (according to their parametricity), and are compared by the student's t-Test or Mann-Whitney U Test, respectively.
Results:
Thirty seven patients were included. The sexes were evenly distributed, with predominantly Caucasians, and a mean age of 56.89 ±15.33. Hypertension and type 2 diabetes were the most frequent comorbidities. Vertebral lumbar level was the most involved segment. Pathogens were identified in 34 cases (91%), with Staphylococcus aureus being the most prevalent, followed by Koch Bacilli. Inflammatory markers are higher in pyogenic infections at hospital admission, but lower at hospital discharge when compared to tuberculous discitis (p<0.01). Mean hospital stay was higher in the pyogenic group.
Conclusion:
The protocol described has a high diagnostic level of the pathogen, with cure of infection and satisfactory neurologic outcome in all cases. Level of Evidence I, Diagnostic Studies - Investigating a Diagnostic Test.
