Implant Sonication versus Tissue Culture for the Diagnosis of Spinal Implant Infection.

ABSTRACT: MINI: We compared the sensitivity and specificity of peri-implant tissue culture to the vortexing-sonication technique for the diagnosis of spinal implant infection (SII). Lower thresholds of sonicate fluid culture positivity showed increased sensitivity with maintained specificity. We recommend a threshold of 20 CFU/10 mL for sonicate culture positivity for the diagnosis of SII.

Study design

This is a retrospective study comparing the diagnosis of spinal implant infection (SII) by peri-implant tissue culture to vortexing-sonication of retrieved spinal implants.

Objective

We hypothesized that vortexing-sonication would be more sensitive than peri-implant tissue culture.

Summary of background data

We previously showed implant vortexing-sonication followed by culture to
