Imaging insights into inflammatory and infective arthritis of the hip joint

A diverse array of inflammatory conditions can impact the hip joint, including septic arthritis, crystal arthropathies, and the involvement of the hip joint in the context of inflammatory polyarthritis. Given the significant overlap in clinical presentations and the complexities associated with physical examinations and laboratory investigations, imaging emerges as a critical tool for accurate diagnosis. It aids in detecting subclinical disease, evaluating disease activity, and informing therapeutic decisions. This article aims to offer a comprehensive overview of the prevalent inflammatory and infectious arthritis affecting the hip joint. It will detail specific imaging modalities and elucidate the integral role of radiologists in this diagnostic process. Furthermore, the discussion will present a methodical approach to assessing patients with inflammatory hip pain, addressing potential conditions that may mimic inflammatory and infectious arthritis of the hip joint.
