Chronic Recurrent Multifocal Osteomyelitis (CRMO) is a rare autoinflammatory bone disease in children. Studies evaluating the quality of life of patients with CRMO are small and heterogeneous. A better understanding of the impact of the disease on the quality of life of adult patients with CRMO beginning in childhood would allow better long-term management of these patients. Our study aims are to assess the clinical and socio-professional outcomes of adult patients who started CRMO at pediatric age.

Inclusion Criteria:

• Adult Patient with a CRMO with pediatric-onset disease (> 18years)
• Patient who was informed and agreed to participate in this study

Exclusion Criteria:

• Patients with Monogenic auto-inflammatory disease associated with osteolytic bone lesions (e.g. interleukin-1 receptor antagonist deficiency)
• Patient with Majeed syndrome
• Patient without sufficient imaging data to confirm the presence of one or more inflammatory lesions
• Patients with incomplete data.
• Patients placed under legal protection, guardianship or curatorship

Adult patients with CRMO disease started at pediatric age. Patients who agreed to participate to the study (study questionnaires during a telephone interview (SF36, HAQ and questionnaire pre-established for the study)
