Infection from one site can extend to adjacent structures, resulting in overlapping and often indistinguishable clinical picture. Clinical and laboratory parameters, including fever, inability to bear weight and elevated inflammatory markers are helpful in distinguishing infectious from non-infectious causes of hip pain. However, they cannot reliably differentiate the site or extent of infection. Blood and local aspirate cultures are crucial for identifying causative organisms, yet a significant proportion of cases are culture negative. Aggressive treatment is required even in culture negative cases if clinical, laboratory, and imaging findings are consistent with infection. Magnetic resonance imaging (MRI) is the modality of choice for defining the site and extent of disease, detecting multiple foci, and guiding surgical planning. Ultrasonography, although less sensitive and specific, may be helpful in settings where MRI is unavailable, especially for identifying joint effusion and guiding diagnostic aspiration.
