Objectives Sickle cell disease (SCD) is associated with femoral head osteonecrosis and is treated with hip arthroplasty 18 weeks after presentation. However, there is inadequate data regarding the timing of surgical management of severe hip arthropathy. This study explores the problem of delayed diagnosis and surgical management of severe SCD hip arthropathy by comparing the clinical outcomes of patients from Nigeria, Canada and Britain. Methods This is a prospective clinical audit of the routine care of 30 adult SCD patients who underwent hip arthroplasty for femoral head osteonecrosis. The clinical data are collected from five medical centers in Britain, Canada and Nigeria and compared. Results Hip arthroplasty was delayed beyond 18 weeks in 3 of 14 Nigerian patients (21%), 7 of 10 British patients (70%) and all 6 Canadian patients (100%). The majority of Nigerian patients (79%) and only 30% of British patients had diagnostic imaging and surgical management without delay. Conclusion Inadequate physician awareness and delayed surgical management of SCD hip arthropathy can be mitigated by improving the education of physicians who manage patients with SCD. It is essential to recruit, train and support physicians with an interest in SCD. As this primarily affects young patients, it is necessary to set an international standard for the timing of surgical management of SCD hip arthropathy.
