Clinical, etiological, and microbiological differences between foot and non-foot osteomyelitis.
Article in Archives of orthopaedic and trauma surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionOsteomyelitis presents with heterogeneous clinical, etiological, and microbiological characteristics depending on anatomical location. While foot osteomyelitis is commonly associated with diabetic foot infections and contiguous spread, non-foot osteomyelitis often arises from post-traumatic, hematogenous, or postoperative causes. However, direct comparative analyses between these two entities remain limited. MATERIALS AND
methodsA retrospective analysis was conducted on 202 adult patients who underwent surgical treatment for osteomyelitis between 2011 and 2026. Patients were divided into foot (n = 89) and non-foot (n = 113) osteomyelitis groups. Clinical, etiological, microbiological, and treatment-related variables were compared. Only intraoperatively obtained deep tissue and/or bone cultures were included.
resultsPatients with foot osteomyelitis were older and had a significantly higher prevalence of diabetes mellitus (49.4% vs. 5.3%, p < 0.001), which was identified as an independent predictor of foot osteomyelitis (OR 14.15, 95% CI 4.32-46.42; p < 0.001). Infections in foot osteomyelitis predominantly developed via contiguous spread (73.0%), whereas non-foot osteomyelitis showed more heterogeneous etiologies, including post-traumatic and hematogenous causes (p < 0.001). Microbiologically, Staphylococcus aureus was the most common pathogen in non-foot osteomyelitis, while foot osteomyelitis demonstrated a more diverse distribution with higher rates of polymicrobial infections. Amputation was significantly more frequent in the foot group (50.6% vs. 15.9%, p < 0.001), whereas antibiotic-loaded cement use was more common in non-foot osteomyelitis (p < 0.001).
conclusionsFoot and non-foot osteomyelitis differ significantly in clinical, etiological, and microbiological characteristics. These findings suggest that foot and non-foot osteomyelitis differ in their clinical, etiological, and microbiological characteristics and may require different diagnostic and therapeutic approaches.
