Hip Infection Key Advice
How sick is the patient? Run lab diagnostics to determine acuity: C-reactive protein (CRP), Erythrocyte Sedimentation Rate (ESR), Complete Blood Count (CBC), Aspirate and evaluate white blood cell count.
If it’s early onset (acute), or less than 2 weeks, open and drain infection. For most hip replacements, this will solve the infection.
If it’s late onset (chronic), more than 2 weeks, successful salvage of the implant is less likely, and explantation of all existing hardware should be considered. After completing 6 weeks of antibiotic therapy, and normalization of CRP and ESR, one may proceed with re-implantation.
