Actinomycosis is rare, chronic, slowly progressive disease caused by gram-positive anaerobic organisms from the Actinomycosis family that normally colonizes the oral cavity. Actinomycotic osteomyelitis is even more rare and refractory disease because diagnosis by bacterial culture is not easy. In our case, 80-year-old man visited our clinic with a complaint of swelling and severe sinus tracts without teeth evolvement on anterior mandible. Computed tomography (CT) scan demonstrated erosive bone destruction on anterior mandible, clinically suspected actinomycotic osteomyelitis. The patient also had thoracic actinomycosis on Lt. lower lung. We could diagnosis actinomycosis by histopathologic examination. He treated by conservative surgery and long term antibiotics. After 2 year, no recurrence was seen in CT scan.

Mucormycosis is a rare, invasive fungal infection that progresses aggressively and requires prompt surgery and appropriate treatment. The number of cases of mucormycosis in coronavirus disease 2019 (COVID-19) patients has recently increased, and patients with uncontrolled diabetes mellitus are particularly at an elevated risk of infection. This report presents a case of mucormycosis-related osteomyelitis of the maxilla in a 37-year-old man with diabetes mellitus. The patient complained of severe and persistent pain in the right maxilla, accompanied by increased tooth mobility and headache. On contrast-enhanced computed tomographic images, gas-forming osteomyelitis of the right maxilla was observed. Destruction of the maxilla and palatine bone then proceeded aggressively. Sequestrectomy was performed on the right maxilla, and the histopathological diagnosis was mucormycosis. Further investigation after the first operation revealed the patient's history of COVID-19 infection.

Recently, the International Working Group on the Diabetic Foot and the Infectious Diseases Society of America divided diabetic foot disease into diabetic foot infection (DFI) and diabetic foot osteomyelitis (DFO). DFI is usually diagnosed clinically, while numerous methods exist to diagnose DFO. In this narrative review, the authors aim to summarize the updated data on the diagnosis of DFO. An extensive literature search using "diabetic foot [MeSH]" and "osteomyelitis [MeSH]" or "diagnosis" was performed using PubMed and Google Scholar in July 2023. The possibility of DFO is based on inflammatory clinical signs, including the probe-to-bone (PTB) test. Elevated inflammatory biochemical markers, especially erythrocyte sedimentation rate, are beneficial. Distinguishing abnormal findings of plain radiographs is also a first-line approach. Moreover, sophisticated modalities, including magnetic resonance imaging and nuclear medicine imaging, are helpful if doubt remains after a first-line diagnosis. Transcutaneous bone biopsy, which does not pass through the wound, is necessary to avoid contaminating the sample. This review focuses on the current diagnostic techniques for DFOs with an emphasis on the updates. To obtain the correct therapeutic results, selecting a proper option is necessary. Based on these numerous diagnosis modalities and indications, the proper choice of diagnostic tool can have favorable treatment outcomes.

Chronic osteomyelitis is an infection and inflammation of the bone or bone marrow, causing ischemia in bone marrow due to lack of blood, nutrients, and oxygen supply to the bone marrow, eventually leading to necrosis of bone marrow. A current method for treatment of chronic osteomyelitis is administration of systemic antibiotics followed by removal of the infected bone and tissues. Because infected tissue of chronic osteomyelitis is surrounded by avascular necrotic bone, supply of blood and antibiotics to the infected area is diminished. For effective treatment, high plasma concentrations of antibiotics should be provided for a prolonged period. However, long term high serum level of antibiotics may result in undesirable adverse effects. For delivery of a sufficient concentration of antibiotic to the infected area while avoiding the adverse effect, implantation of a local antibiotic delivery system is suggested. One of the implantation systems that has been utilized is antibiotic impregnated polymethyl methacrylate.

To Appreciate the value of bone scintigraphy in determination of the bony infection, we performed three phase bone scintigraphy in 34 cases of osteomyelitis of extremities prospectively. They were clinically inactive in 11 and active in 23 cases. We confirmed the active osteomyelitis by operation or aspiration within one week after scintigraphy. Perfusion, blood pool and delayed images were analyzed respectively and compared with the plain roentgenograms. All 23 active lesions showed diffusely increased perfusion in affected limbs. The areas of the increased activities on blood pool images were larger than or similar to those on delayed images in 17 cases (73.9%) with active osteomyelitis and smaller in 6 cases (26.1%). 5 of the latter 6 cases showed definite soft tissue activities on blood pool images. In inactive cases bone scintigrams were completely normal in 4 cases. Two of those were normal on plain films and remaining two showed mild focal bony sclerosis. Among 7 inactive lesions, perfusion was normal in 2 cases, diffusely increased in 4 cases and diffusely decreased in 1 case. 6 of these 7 cases showed increased activities both on blood pool and delayed images and the areas of increased activities on blood pool images didn't exceed those on delayed images. Bony sclerosis was noted on plain films in those 7 inactive lesions and the extent of the sclerosis correlated well to delayed images. Large blood pool activity was characteristics of active osteomyelitis. Normal three phase bone scintigram may indicate the time to terminate the treatment, but increased activity on perfusion and blood pool scans is not absolute indication of active lesion if the extent of the lesion on the blood pool image is smaller than that on delayed image and if no difinite soft tissue activity is noted on perfusion and blood pool images in clinically inactive patient.

Purpose: Percutaneous Kirschner wire fixation is common method for hand fracture. It is simple but has risk of ascending infection through the pin and bony injury by multiple drilling. Ascending infection through pin tract is mostly superficial and can be treated with antibiotics and aseptic dressing. This is a case review of subacute osteomyelitis on phalangeal bones after Kirschner wire fixation with literature review. Methods: A 40-years-old man with distal phalangeal fracture on right second finger is presented. He went to a local clinic and had percutaneous Kirschner wire fixation under local anesthesia. He was transferred to our hospital for ulcerative wound on DIP joint at 4 weeks after operation. Radiography showed osteolytic change around medulla of middle and distal phalanges, leading to diagnosis of a subacute osteomyelitis. We treated it with amputation at the level of shaft of middle phalanx. Results: The postoperative course was uneventful. We thought several possible reasons for osteomyelitis in our case. First, it could resulted from ascending infection through the wire. Second, it could be resulted from a bony burn by repeated drilling. And bony necrosis could be a consequence of arterial insufficiency caused by 2 pin insertion. Conclusion: We suggest that a precise pinning based on accurate anatomical understanding is required for a percutaneous Kirschner wire fixation. The frequency of drilling should be minimized. Careful observation and patient education for pin site care are essential.

Purpose: To cover the exposed tendons and bones after trauma and cure the concomitant osteomyelitis in the lower extremities, gracilis muscle free flaps are frequently preferred. 32 cases of gracilis muscle free flap we had done were analysed according to the indications, specification of flap length and width, pedicle length, vessels used in the anastomosis and final healing after at least over 1 year follow up. Materials and methods: From August 1995 through November 2002, we have performed 32 cases of gracilis muscle free flap transplantation with the general microsurgical procedures in the lower extremities. Open fracture of the middle and distal tibia were 12, exposed heel 6, crushing injury in the foot 5 cases, open fracture of the ankle 4, chronic osteomyelitis of the tibia 3 and osteomyelitis of the tarsal bones 2. Tailored flap length were ranged from 16 cm to 4 cm, width were from 5cm to 4cm. Pedicle length averaged around 4 cm. Anastomosis of one artery and two veins in both of donor and recipient were performed in 17 cases and one artery and one vein in 15 cases. Results: All flaps were survived, except 2 cases. Final flap healing was satisfactory to both of the patients and microsurgeon. Conclusion: Gracilis muscle free flaps are frequently chosen to cover the exposed components and cure the osteomyelitis in the lower extremities.

Two thousand-two hundred-forty-three cases of various lesions of the oral and maxillofacial region in children under 16 years of age were reviewed. The lesions were classified by 10 groups; osteomyelitis, cysts, benign tumors, malignant tumors, fibro-osseous lesions, developmental disturbances, antral lesions, TMJ lesions, salivary gland lesions, and other lesions. The obtained results were as follows; 1. Developmental disturbances, especially cleft alveolus and palate, was the most common lesions (25.7％), followed by cysts (22.5％), antral lesions (12.7％), benign tumors (11.9％) and osteomyelitis (9.3％). 2. With the time, the incidence of osteomyelitis and malignant tumors has been decreased, but that of developmental disturbances, cysts and antral lesions has been increased. 3. The sex distribution was relatively equal for the entire series, with male predominence in cysts, malignant tumors, developmental disturbanes and salivary gland lesions and with female predominence in TMJ lesions. 4. Children with malignant tumors and osteomyelitis were somewhat younger and those with TMJ lesions were somewhat older. 5. Heading the list of each group except osteomyelitis was dentigerous cyst, odontoma, malignant lymphoma, fibrous dysplasia, cleft alveolus and palate, inflammatory change, degenerative change of condylar process, sialolithiasis and simple bone cyst respectively.

Fracture site osteomyelitis begins rarely with an acute event but rather has a subacute onset. It develops almost exclusively in the mandibular region. The treatment principles of mandibular fracture site osteomyelitis are complete removal of inflammatory tissue and drainage, rigid fixation with or without autogenous bone bone graft and specific antibiotic therapy. But hyperbaric oxygen used as a modality in the treatment of intractable osteomyelitis. In this paper, we reported that the three patients who have osteomyelitis accompying secondary in fection after mandibular fracture.

Primary sternal osteomyelitis is a rare disease. Primary sternal osteomyelitis occurring during childhood is extremely rare; therefore, only eleven cases have been reported in the English language literatures. The predisposing factors of primary sternal osteomyelitis are malnutrition, immune deficiency, intravenous injection, blunt chest trauma, and sickle cell anemia. Drainage of pus with antibiotic therapy is the treatment of choice. We report a case of primary sternal osteomyelitis occurred in a 16-year old boy, who had no predisposing factors, with review of literatures.
