Changes in marrow fat in femur and vertebrae will be quantified using CT and MRI images analysed using an image analysis software (Tomovision).
Timepoint [1] 261994 0
6 months and 18 months post-infusion
Secondary outcome [1] 265598 0

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be contacted by our fracture care coordinator. After signing the consent form, the participant will be randomised into either the treatment or the placebo group.
Medication will be prepared by a doctor not involved with study participants. The medication will be then administered by a study nurse who is unaware of the contents. Thus all study personnel with patient contact will be blinded.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer-generated random numbers in variable blocks.
Masking / blinding
Blinded (masking used)
