Abstract
We wished to determine the frequency and significance of cold bone defect on granulocytes labelled with technetium-99-m-hexamethylpropyleneamine oxime (99mTc-HMPAO-PMN) in non-spinal bone infection. Cold bone defect was investigated as part of a retrospective review during a 2-y period. Patients who had possible osteoarticular infection underwent bone scintigraphy combined with 99mTc-HMPAO-PMN for diagnosis and follow-up. Osteomyelitis was confirmed by isolation of the responsible pathogen. Among 210 patients who had possible infection, 17 (8%) demonstrated a cold bone defect. The site of cold bone defect was for all patients the hip. All 17 patients had proven bacterial orthopaedic hardware-related infection. The single causative micro-organism was staphylococcus. Whatever the outcome, cold bone defect was constant regardless of follow-up equal to or longer than 18 months. These data suggest that this uncommon scintigraphic pattern is an indication of an infectious process similar to increased uptake.
