Septic pseudarthrosis of long bones are complications that can unfortunately occur after the consolidation of a fracture and some situations present risks of superinfection, persistent infection or mechanical failure (30-40% risk of complications) that can lead to amputation.

A possible saving situation used by CRIOAC ("Centre de Référence des Infections Ostéo-Articulaires Complexes") is the use of a bone substitute impregnated with an antibiotic allowing a high local concentration of this antibiotic.

The aim of this study is to evaluate the cost of management of septic pseudarthrosis with two-stage treatment and CERAMENT® and the quality of life for this patients.

Inclusion Criteria:

• age ≥ 18 years old
• Diagnosis of septic pseudarthrosis
• septic pseudarthrosis managed by the surgical technique using the CERAMENT bone substitute combined with an autograft / allograft by the Masquelet technique OR, for the comparative cohort: septic pseudarthrosis on long bone previously managed by the masquelet method without CERAMENT®
• Medico-surgical management within the CRIOAC ("Centre de Référence des Infections Ostéo-Articulaires Complexes") of the Croix-Rousse hospital in Lyon
• Patient who was informed and did not object to participate in the study

Exclusion Criteria:

• Patient with a disability (deafness, language disorders) or whose mental or cognitive state does not allow to be informed and to express his opposition if necessary.
• Patient with a disability (deafness, language impairment) or whose mental or cognitive state does not allow to understand the questions in the quality of life questionnaire
• Patient participating in another quality of life study
