Outcomes
Primary outcome [1] 291225 0
Differences in the rates of fracture healing on computer tomorgraph (CT) scan.
Fracture healing will be defined as: any evidence of bony callous bridging (either disorganised, cloud-like or mature, remodelled bony callous) at the fracture line (at any pelvic fracture site) as judged by two independent, blinded radiologists. Where there is an initial inconsistency between the two radiologists, discussion will be held between them, until a consensus can be reached.

Cost effective of teriparatide over standard care

This will be assessed with the use of a Markov model to calculate an incremental cost-effectiveness ratio for teriparatide over standard care. The cost will be determined from the perspective of hospital utilisation (as outlined above, using DRG data) with quality adjusted life years (QALYs) saved calculated using quality of life data from the AQOL-6 instrument.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Investigators involved in the assessment of outcomes will be blinded to the group allocation. Only a research nurse and a single investigator (the investigator that will perform the education of teripartide injection and follow up) will be aware of the patient’s treatment allocation.

Allocation concealment will be performed by an unblinded investigator or the unblinded research nurse using sealed opaque envelopes. These investigators will not be involved in any of the outcome assessments.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will occur using a random number generator within Microsoft Excel, producing 40 random numbers. Patients assigned an even number will be allocated to group 1 (treatment group) and odd numbers to group 2 (standard care). Randomisation will occur on a 1:1 basis.

Efficacy
Statistical methods / analysis
Statistical analysis will be performed on an intention-to-treat basis.
Patient characteristics will be summarised and compared between the intervention and control group. The primary outcome will be analysed using Pearson’s Chi-squared (or Fisher’s exact tests, if required) as will other categorical variables. Continuous variables will be compared using t-tests (for normally distributed data) and Wilcoxon rank sum or Kruskal-Wallis (for non-parametric data).
Pre-specified subgroup analysis will occur, with each group divided into those that had had any anti-resportive osteoporotic treatment in the preceding twelve months and those with no previously anti-resportive osteoporotic treatment, or treatment greater than twelve months prior.
AQOL-6 data will be used to calculate differences in participant group utility (mean), which, along with health care cost data, will be used in Markov modelling to calculate an incremental cost-effectiveness ratio for teriparatide over standard care. Sensitivity analysis will be used to assess for the amount of uncertainy in the model.

Summary
Brief summary
Teripartide is a medication that works on cells within the bone (called osteoblasts) to help form new bone which is
approved in Australia to treat osteoporosis. A previous, but flawed study has shown some promising results with the
use of parathyroid hormone (a medication very similar to teriparatide). There is also some inconsistent evidence of
improved fracture healing after wrist fractures. Preclinical
studies in rats have also shown some evidence of faster
fracture healing.
We will perform a small, pilot, randomised trial assessing the effect of 8 weeks of teriparatide on fracture healing.
We will recruit up to 40 participants who have had a minimal trauma pelvic fracture, who would otherwise undergo conservative management, who can either selfadminister or have a carer able and willing to administer daily subcutaneous injections for 8 weeks. Each participant will be randomised to either the treatment (20 micrograms
per day of teriparatide via subcutaneous injection) or standard care (pain relief, physiotherapy).
Our primary aim is to demonstrate (assessed on computer tomography scan) that a larger proportion of participants
will have demonstrable cortical bridging (fracture healing) at the fracture site after 8 weeks of treatment. Secondary
aims will be to demonstrate improvements in pain, functional status and quality of life after 4, 8 and 16 weeks.
This study will guide us in the design of a larger, multicentre
trial, if the initial results show promise.
