Ages Eligible for Study:   18 Years to 75 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Adult patients (between 18 and 75 years) affiliated with an appropriate social security system, diagnosed as suffering from symptomatic ORN, radiologically confirmed, for which surgery is indicated
  • Presence maximum of 2 outbreaks of ORN
  • Oncological remission of the original tumor site for 1 year and for 3 years if the ORN is in the contact or close to the initial tumoral site

  • ORN symptomatic accessible to the conservation of at least one cortical mandibular basilar
  • Signed informed consent

Exclusion Criteria:

  • Oncological treatment
  • Haematologic background
  • Current bone necrosis consecutive or concurrent to taking bisphosphonates
  • Extension of ORN does not allow the retention of a mandibular rod (bicortical form)
  • Presence of fracture complicating ORN
  • Bisphosphonates during the last year
  • Contraindications to the removal of iliac or sternum bone marrow
  • Contraindication for general anesthesia
