About the study
Chronic recurrent multifocal osteomyelitis, also known as chronic nonbacterial osteomyelitis (CNO), is a rare autoinflammatory bone disease. It is characterised by bone pain and swelling. CRMO/CNO occurs primarily in children and teenagers. There is a spectrum of severity with mild cases only requiring nonsteroidal anti-inflammatory drugs (NSAIDs) for disease control, compared to severe cases with serious complications such as vertebral fracture, who require multiple medications such as bisphosphonate and immunosuppressants.
Though first described over four decades ago, we still do not know how common CRMO/CNO is. Therefore, this study intends to determine the incidence of CRMO/CNO in the UK and the Republic of Ireland. We will also analyse the disease epidemiology, clinical and radiological features, how CRMO/CNO is managed currently, and two-year outcomes.
The study has now been extended to carry out surveillance for a further year.
Children and young people up to but not including the age of 16 years with a new diagnosis of possible CRMO/CNO, namely those who have the following features:
- The presence of localised bone pain, which could be single site or multiple sites
- The presence of typical radiological findings on plain X-ray (examples include: lysis, sclerosis, cortical thickening or periosteal reaction) or on MRI (examples include: bone marrow oedema on fluid sensitive sequences, or periostitis (periosteal inflammation))
- The treating clinician has determined that the clinical features are not explained by an alternative diagnosis, eg trauma, infection or neoplasm
Please report children/young people up to the age of 16 years with new diagnosis of possible CRMO/CNO in the last month in the UK and Republic of Ireland.
October 2020 to October 2022 (24 months of surveillance).
Follow-up until October 2024 (24-month follow-up).
The study is funded through the Sir Peter Tizard Bursary, two grants from Addenbrooke's Charitable Trust and a grant from the British Society of Skeletal Radiologist (BSSR)

We will collect information about children and young people diagnosed with CRMO/CNO from the doctors who are looking after them. Doctors will not provide identifying information like names and addresses, but they will provide personal information like sex, ethnic group and date of birth. The smallest amount of personal information will be used. We cannot withdraw or remove information from the study but personal information will be deleted or de-personalised when the study finishes. Cambridge University Hospitals NHS Foundation Trust will securely store this information for 20 years.
If you want access to the information in your child’s NHS records, then you should contact your child’s NHS hospital/doctor.
