Management of Herniated Disc with Elevated WBC Count

Evaluation and Infection Workup

An elevated WBC count (>14,000 cells/mm³) or a left shift (percentage of band neutrophils >16% or total band neutrophil count >1,500 cells/mm³) warrants careful assessment for bacterial infection, with or without fever, according to the Infectious Diseases Society of America 1, 2
Leukocytosis with a WBC count >14,000 cells/mm³ has a likelihood ratio of 3.7 for detecting bacterial infection, as reported by the Infectious Diseases Society of America 1
A complete blood count with differential should be performed to evaluate the elevated WBC count, as recommended by the American Geriatrics Society 3
Consider potential sources of infection that may be causing the elevated WBC count, including urinary tract infection, respiratory infection, and discitis or vertebral osteomyelitis, according to the Infectious Diseases Society of America 1, 3, 4
Additional diagnostic tests, such as blood cultures and MRI with contrast, should be guided by clinical presentation, as suggested by the American Geriatrics Society and the American Society of Clinical Oncology 4, 5

If signs of systemic infection are present, prioritize infection workup and treatment, according to the Infectious Diseases Society of America 1, 3
If localized infection is suspected in the spine, obtain appropriate imaging and infectious disease consultation, as recommended by the American Society of Clinical Oncology 5
Treat the underlying infection with appropriate antimicrobial therapy before addressing the herniated disc, according to the Infectious Diseases Society of America 1
Avoid invasive procedures related to disc management until infection is controlled, as suggested by the American Society of Hematology 6

Avoid invasive procedures such as central venous catheterization, lumbar puncture, and surgical interventions while active infection is present, as recommended by the American Society of Hematology 6
Monitor WBC count to ensure resolution if infection was identified, according to the Infectious Diseases Society of America 1
