Hip joint rice body bursitis combined with hip dysplasia and pelvic fracture: a case report.

Abstract

Background: Rice body formation is an uncommon, nonspecific inflammatory process. Certain clinical features, such as chronic synovitis associated with rheumatoid arthritis, tuberculous arthritis, and osteoarthritis, can induce a non-specific response that may lead to the development of rice bodies. Currently, the etiological and prognostic significance of rice bodies remains unknown. Magnetic resonance imaging (MRI) is the preferred diagnostic imaging modality for evaluating rice body formation.

Case presentation: The patient, a 44-year-old female, presented with bursitis of the hip joint and the presence of numerous rice bodies. This case is exceptionally rare and unusual as it involves a combination of hip dysplasia and pelvic fracture. The patient underwent a one-stage resection of the rice body, internal fixation of the acetabular fracture, and two-stage total hip arthroplasty, resulting in an immediate improvement in her symptoms. We reviewed the relevant literature and observed that the majority of rice bodies were predominantly found within the capsules of the shoulder and knee joints, while instances of hip joint rice body bursitis were relatively infrequent. To our knowledge, there have been no previous reports documenting a case of hip joint rice body bursitis in conjunction with hip dysplasia and pelvic fracture.

Conclusion: This paper presents the rare case of hip joint rice body bursitis combined with hip dysplasia and pelvic fracture, and is one of the highlights.
