MRI Manifestations and Diagnostic Value of Chronic Osteomyelitis

Abstract

If chronic osteomyelitis is not treated promptly and thoroughly, the wound will not heal for a long time, and the affected limb will be dysfunctional or disabled. In severe cases, it may even require amputation. In this article, a total of 50 patients with chronic osteomyelitis who meet the inclusion criteria were selected from January 2019 to March 2020 and were divided into two groups based on patient compliance, namely, a treatment group and a control group. The results of this group of studies showed that osteomyelitis is mostly manifested as limited diffusion, showing high signal on DWI, and ADC value is significantly higher than that of normal bone area. The normal bone area did not show obvious focal abnormal signals on the conventional MRI image. The ADC value of the measured patient’s osteomyelitis area was compared with the ADC value of the normal bone area. The ADC value was significantly higher than that of the normal bone area, and the difference was statistically significant. Studies have shown that membrane induction technology is superior to the bone handling group in terms of limb function scores and results satisfaction in the treatment of chronic osteomyelitis bone defects. Membrane induction technology has a low complication rate, a small number of X-ray examinations, a short healing time, and a high functional score. However, bone handling technology has a long treatment process, long fixation time and healing time, nail channel infection, joint stiffness, nerve damage, and many other complications.

Predictive Value of Radiographic and Magnetic Resonance Imaging Characteristics on Patient Outcomes in Confirmed Acute Osteomyelitis of the Extremities

“…The results of the analysis of this single-center study with 75 consecutive cases of confirmed extremity OM demonstrate that none of the imaging characteristics assessed on MR or XR modalities are predictive of a patient's outcomes and midterm survival rates. Although studies have shown that MR is a more accurate modality for diagnosing and determining the extent of OM, 15–18 our hypothesis of predictive capability of imaging findings for patient outcomes was refuted. Radiographs, although routinely used as the initial imaging modality for OM, also exhibited no significant predictive value for prognostication of OM-related outcomes.…”

“…Alternatively, ultrasonography was an upcoming promising screening tool as it has the ability to show acute findings of extraosseous pathology and/or periosteal elevation in osteomyelitis at an earlier stage [ 8 ]. MRI is the imaging modality of choice for the diagnosis of osteomyelitis and shows marrow edema typically presents as a localized marrow abnormality of decreased signal on T1-weighted images and increased signal on T2-weighted images [ 9 ]. The most acute finding of osteomyelitis on MRI is bone marrow edema or indirect findings of osteomyelitis such as soft-tissue collections, cellulitis, and cortical bone sinus tracts.…”

“…The bone scan is useful in multifocal diseases in particular, because easy to scan the whole body. However, the gold standard tool remains tissue biopsy and culture [ 9 , 10 ].…”
