Typical clinical signs of acute osteomyelitis

Acute osteomyelitis is an inflammation of the bone caused by bacterial infection. Typical clinical signs include local pain, fever, redness, swelling and functional impairment. Early diagnosis and timely treatment are key, usually with antibiotics, surgical debridement and adjuvant therapy.

1. Local pain and swelling: The most common symptom of acute osteomyelitis is severe pain at the site of infection, often accompanied by local swelling and tenderness. The pain may worsen with activity and ease after rest. The swelling is due to the inflammatory response that causes local vasodilation and fluid exudation. In terms of treatment, the early use of broad-spectrum antibiotics such as ceftriaxone, vancomycin or clindamycin can effectively control the infection.

2. Fever and systemic symptoms: Patients often have systemic symptoms such as fever, chills, and fatigue. Fever is the body's natural response to infection, and the body temperature usually exceeds 38.5°C. The appearance of systemic symptoms indicates that the infection may have spread throughout the body. In addition to antibiotics, symptomatic treatment is also required, such as the use of antipyretic drugs such as acetaminophen or ibuprofen.

3. Functional impairment: The joints or limbs at the site of infection may have limited mobility, or even be unable to move in severe cases. Functional impairment is muscle spasms and joint stiffness caused by inflammation and pain. In terms of treatment, in addition to antibiotics, physical therapy such as hot compresses, massage, and moderate exercise can help restore function.

The treatment of acute osteomyelitis requires a combination of multiple approaches, and early diagnosis and timely treatment are crucial. Antibiotic treatment is the basis, surgical debridement is performed when necessary, and auxiliary therapies such as physical therapy and nutritional support also help recovery. Patients should strictly follow the doctor's advice and have regular checkups to ensure that the infection is completely controlled and to avoid recurrence and complications.
