title: Bilateral Total Hip Arthroplasty in a Rare Case of Multicentric Reticulohistiocytosis.
abstract: Multicentric reticulohistiocytosis (MRH) is a rare systemic disease, which commonly manifests as muco-cutaneous papulonodules and inflammatory erosive polyarthropathy. In this research, we report the clinical manifestations and management of a rare case of MRH with destructive arthropathy of bilateral hip joints and arthritis mutilans presenting with characteristic deformities. Disabling hip arthropathy that occurs secondary to MRH can be successfully managed with bilateral total hip arthroplasty (THA). Osteopenia and acetabular bone defects must be anticipated during THA. This case is reported due to its rare occurrence and because little literature has been published regarding THA in such patients.
