Two-stage Treatment of Large Bone Defects With Cerament® G and Cerament® V Plus Auto and/or Allograft Using the Masquelet Technique as Salvage Therapy After Bone Resection in Patients With Septic Pseudarthrosis

Study Overview
=================
Brief Summary
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Cost evaluation | Estimation of the cost of care from the point of view of the hospital This estimation will be measured at the end of patient follow-up (usually between 12 and 24 months after antibiotic therapy disruption) | 24 months maximum |
