PURPOSE: Fracture-related infections (FRIs) encompass a broad range of infections associated with bone fractures; they remain a significant clinical challenge. Here, we aimed to investigate the viability of focusing on soft-tissue management in patients suspected of chronic FRI, who exhibit no significant bony uptake on bone single photon emission computed tomography (SPECT)/computed tomography (CT) scans.
METHODS: Between January 2016 and January 2022, we managed 25 patients with chronic FRI or post-traumatic osteomyelitis using technetium 99m-methyl diphosphonate bone SPECT/CT to assess infection depth. Among them, 13 patients showing negligible bony uptake were included and categorized into two groups based on wound discharge reaching the bone/implant (Criteria 1, n = 6) or not (Criteria 2, n = 7).
RESULTS: Patients in the Criteria 1 group were treated with antibiotics and soft tissue debridement without bony procedure. The average duration of antibiotic therapy was 6.7 weeks. Treatments were individualized, including implant changes, local flaps, skin grafts, and negative pressure wound therapy. No recurrence was reported in the mean follow-up of 21.3 months. Patients in the Criteria 2 group were treated with oral antibiotics (mean duration: 5.9 weeks) and daily wound dressings. No recurrence was reported in the mean follow-up of 26.0 months, and no surgical interventions were required.
CONCLUSION: This study demonstrates the feasibility of focusing on soft-tissue management in patients with chronic FRI showing minimal bony uptake on bone SPECT/CT. Our treatment protocol avoided unnecessary surgical bone procedures, resulting in successful clinical outcomes with no recurrences.
