Osteomyelitis is an inflammatory disease caused by septic bacterial infection of the bone marrow, bone cortex and periosteum, mostly of hematogenous origin, but also caused by trauma or surgical infection, mostly from boils and carbuncles or other foci of septic viruses entering the bloodstream and reaching the bone tissue. The bones of the extremities are the most susceptible, and the hip joint is the most common. It is common to have recurrent attacks that seriously affect physical and mental health and work capacity. Acute osteomyelitis starts with high fever and localized pain, and when it turns into chronic osteomyelitis, there will be ulceration, pus flow, dead bone or cavity formation. Severe cases are often life-threatening, sometimes necessitating emergency amputation, resulting in lifelong disability. Differential diagnosis: Patients with this disease often present with limited bone pain, fever and discomfort suggesting osteomyelitis. Blood leukocyte counts may be normal. X-ray changes appear 3 to 4 weeks after infection. Bone destruction, soft tissue swelling, and subchondral bone plate encroachment may be seen. Narrowing of the intervertebral disc space and bone destruction with shortening of the vertebral bones are seen. If the x-ray presentation is unclear, CT examination is feasible to identify the lesioned bone and to show the formation of paravertebral abscesses. Radiological bone scan is reflected in the early stage of the lesion but cannot distinguish between infection, fracture and tumor by puncture biopsy and surgical biopsy of the intervertebral disc space or infected bone.
